Results And Dicussion

Candida ntolischiana 35M5N mutant screening Following incubation with the mutagenic agent (MNNG) for 45 min at 37 C and seven enrichment cycles, the resulting cells were inoculated on agar plates containing cellobiose (5 g 1) and 2-deoxyglucose (1.2 g 1). Several colonies were detected, isolated after 5-day incubation period and identified as Candida molischiana. One colony was selected and the growth curve of this strain on the mineral medium (+ cellobiose, 5g l) was compared to that of the wild type. The doubling time of the mutant was shorter (3.5 h) than that of the wild type (5 h). The mutation was stable for other 50 generations 6 . Analysis of B-glucosidase activity of the mutant strain during its growth on mineral medium (+ cellobiose. 5g 1) showed that its specific activity at the end of the log phase was identical to that of the wild type (1.4 ratio). This Candida molischiana 35M5N mutant is thus not a hyperproducer. However, table 1 shows the ratio of the exocellular...

Stereopreference Of Lipases

Figure 3 shows the effect of substrate solubilisation on the stereopreference of a lipase from Candida rugosa. Three different systems were used for the dispersion of the labeled alkyldiacylglycerols in water, namely albumin, alkylsulfobetain micelles, or ethanol. Indicated are the relative enzyme activities towards the s -l and sn-3 acyl enantiomers of the fluorescent lipid represented by filled and empty bars, respectively. Figure 3. Effect of substrate solubilisation on stereoselectivity of a lipase from Candida rugosa. Substrates were 1-acyl and 3-acyl enantiomers of fluorogenic alkyldiacylglycerols solubilised in water in the presence of albumin (complex), ethanol, or alkylsulfobetain (micelles).

Methods

The yeast strains Candida molischiana 35 5 and 35M5N 6 , Candida entomophila 7 , Zygosaccharomyces bailii 8 were isolated in our laboratory. The others strains come from culture collection. The basal culture medium was G medium to which carbon sources were added to a final concentration of 0.5 (w v). The cultures were incubated at 28 C in Erlenmeyer flasks filled to one tenth of their volume. Growth was monitored by measuring the absorbance at 420 nm. The cultures were incubated at 28 C and shaken (80 oscillations per min, 8 cm amplitude).

Phenyl and 2 heterocyclylethylazoles

1,2-Diaryl-1(1H-imidazol-1-yl)ethanes 2.28 are active against a number of Candida species. 2.176, 2.177 1,3-Bis(1,2,4-triazol-1-yl)propane derivatives such as 2.32 are claimed for their strong antimycotic action against Candida kidney infection of mice. 2.203, 2.204 A parenteral formulation has been developed. 2.205

XHalogeno and xydihalogenoalkyl1Hazoles

2-Halogenoalkyl-1-azolylalkanes can be prepared from the azole, an aldehyde and sul-furyl chloride, and have been claimed as fungicides. 2.206, 2.207, 2.208 1-Fluoro-1-azolyl-2,2-diarylethanes show inhibition of Staphylococcus aureus and Candida albicans . 2.209 Compounds related to 2.34 incorporate a second azole ring in place of the per-fluoroalkyl group and inhibit Candida albicans infection in mice. 2.219, 2.220, 2.221, 2.222, 2.223

ASubstituted 12hydroxyalkyl1Hazoles

They can also be prepared by addition of aldehydes RCHO to These compounds with Az 1-pyrazolyl, Im or Tr have been claimed as fungicides. 3.043, 3.044, 3.045 . For example, one derivative with Az Tr and R 2,4-Cl2C6H3 controls barley net blotch, broad bean grey mold leaf spot, bean powdery mildew and grape downy mildew. 3.041 Other compounds with R 4-ClC6H4 are weakly active against Candida albicans and with Az Tri, moderately active against Candida sp. (C. glabrata, C. tropicalis, C. guil-lermondii, C. krusei, C. parapsilosis, C. lipolytica). 3.046 Another similar substance with Az Tr, R 4-(bromophenoxy)-2-chlorophenyl controls Venturia inaequalis and Erysiphe graminis. 3.047

[2Halogenophenylmethyloxyalkyl1Himidazoles the econazolemiconazole family

The 5-sulfosalicylates of econazole and miconazole show improved activity against vulvovaginal candidiasis, Trichomonas vaginalis, and Gram-negative bacteria compared with the usual nitrates, which is explained by the their higher lipo-philic character. 3.466, 3.467, 3.468, 3.469, 3.470 The usefulness of miconazole has been critically reviewed. 3.504 It is still generally used against dermatophytic infections of the skin, tinea versicolor, cutaneous and vaginal candidiasis. 3.505 There is scattered evidence of its activity against Propionibact. acnes, 3.506, 3.507 subconjunctival candidal keratitis, 3.508, 3.509 palatal and oral candidiasis, 3.510, 3.511 Neisseria gonorrhoeae, 3.512 and its use as an antiperspi-rant. 3.513 Of rarer microbial pathogens, miconazole inhibits Candida endophthalmi-tis, 3.514 Helicobacter pylori, 3.515 Malassezia furfur, 3.516 Mucor ramosissimus, 3.517 Plasmodium falciparum, 3.518 Rhizoctonia sp., Paecilomyces lilacinus and Fusarium solani. 3.519 Econazole...

Other Fungal Infections

Candida albicans,152 Coccidioides immitis,153 Histoplasma capsulatum154 and mucormycosis155 may all produce meningoencephalitis. Aspergillus fumigatus156 produces brain abscesses in immunocompromised hosts. Since cultures for fungi are frequently negative, brain biopsy may be needed to reveal pseudohyphae, yeasts and filaments. Despite anti-fungal treatment, recurrence is frequent. Severe infections may require surgical debridement.

The Mitochondrial Genome 411 Introduction

Although most of the organisms examined have circular mtDNAs, occasionally the discovery of linear mitochondrial DNAs is claimed. Initially dismissed as artifact, or as a very rare exception to the circular genomes expected from a prokaryotic ancestor, the number of such examples has grown over the past few decades. Diverse organisms from among the ciliata (for example, Paramecium aurelia), the algae (Chlamydomonas reinhadtii), the fungi (Candida, Pichia, and Williopsis species), and oomycetes are represented in a recent review of this subject 11 . An even more radical view gaining acceptance is that at least in plants and fungi (including Saccha-romyces cerevisiae) the major form of mtDNA in vivo is linear 11 . The physical size of these linear mtDNAs is in the 30-60 kb range. Several criteria have been defined by investigators to distinguish true linear mtDNAs from linear concatomeric molecules arising from rolling circle mechanisms of DNA replication and other mechanisms. The most...

[2Alkoxy or alkyHhioethenyl1Maoles

In vitro activity with or without serum against a number of pathogenic fungi is considerably higher than that of clotrimazole or miconazole and similar to that of bifonazole. 3.633 It is especially active against Candida glabrata, Trichophyton, Microsporum, Aspergillus and Fonsecaea spp. 3.623, 3.630 Clinical experience demonstrated neticonazole as a safe and effective treatment of mycoses like tri-chophytosis, candidiasis, and different types of tinea. 3.631 Topical formulations with reduced skin irritation have been claimed. 3.634

Case Study Iii Triazolopyridazines 241 Origin of the Triazolopyridazine Lead

High-throughput screening of our compound collection using the fluorescence polarization assay provided approximately 30 reproducible and interesting hits. Of these, amino pyrimidine 4 was most potent (IC50 58 pM). NMR binding studies confirmed that 4 interfered with FtsZ binding by binding to ZipA in the solvent-exposed cavity used to bind FtsZ and an x-ray structure of the complex of 4 with ZipA was subsequently obtained and used to guide further development of this series. Unfortunately, follow-up testing of 4 showed nonspecific toxicity toward both bacteria and eukaryotes (represented by Candida albicans). Additionally, amine-substituted pyrimidines are heavily covered in the patent literature in the context of kinase inhibition, antitumor, and antiviral activity and designing analogs that fell outside of prior claims would be extremely challenging. It was thought that a search of the structures of compounds in Wyeth's corporate compound collection using a shape-based...

Dihydroxyalkyl1Hazoles and their ethers

Best compounds 3.107 in the therapy of subacute systemic murine candidiasis agree in Az Tr, R' H and R 4-F-C6H4- 3.865 in some series R triazol-1-ylmethyl is favored. 3.873 candidiasis and Aspergillus fumigatus infection of mice and display topical efficacy against Trichophyton metagrophytes infection of guinea pigs. Their fungicidal value has been demonstrated in their inhibition of Puccinia recondita and P. gra-minis on wheat, Erysiphe graminis, Fusarium, Pyrenophora teres and Cochliobo-lus sativus on barley, Botrytis cinerea on paprika, Sphaerotheca fuliginea on cucumber, Pyricularia oryzae on rice, and venturia inaequalis. Some also show plant growth-regulating properties. Optical resolution has been achieved by chromatographic separation of the d-(+)-camphor-10-sulfonates. 3.879, 3.880 Pure enantiomers, (-)-S-form 3.108B, Bay R 2302, and (+)-R-form 3.108C, Bay R 2303 have been synthesized. From these, Bay R 2302 is much more active against Candida albicans, Torulopsis gla-brata...

Copper Imidazole Derivatives Complexes

Chelating donor ligands as N,N'-1,10-phenanthroline (phen) are potent in vitro inhibitors of the growth of Candida albicans, a commensal of the human body considered to be an important fungal pathogen which is often fatal in immuno-compromised patients.55,56 Phen itself and its metal complexes represent a novel set of highly active anti-fungal agents whose mode of action is significantly different from that of the state-of-the-art polyene and azole prescription. Additionally, benzimidazole and many of its derivatives exhibit a variety of biological actions, including anti-bacterial, -viral, -cancer and -fungal activity.57

Apnea Of Preterm Infants

Seasonal allergic rhinitis (hay fever) is caused by deposition of allergens on the nasal mucosa, resulting in an immediate hypersensitivity reaction. This reaction usually is not accompanied by asthma because the allergenic particles are too large to be inhaled into the lower airways (e.g., pollens). Treatment for allergic rhinitis is similar to that for asthma. Topical glucocorticoids, including beclomethasone (beconase), mometasone (nasonex), budesonide (rhinocort), flunisolide (nasarel), fluticasone (flonase), and triamcinolone (nasacort), can be highly effective with minimal side effects, particularly if treatment is instituted immediately prior to the allergy season. Topical glucocorticoids can be administered twice daily (beclomethasone and flunisolide) or even once daily (budesonide, mometasone, fluticasone, and triamcinolone). Cromolyn usually requires dosing three to six times daily for full effects. Rare instances of local candidiasis have been reported with glucocorticoids...

Management of anal fissures

Anal and perianal pruritus, soreness, and excoriation are best treated by application of bland ointments and suppositories (section 1.7.1). These conditions occur commonly in patients suffering from haemorrhoids, fistulas, and proctitis. Cleansing with attention to any minor faecal soiling, adjustment of the diet to avoid hard stools, the use of bulk-forming materials such as bran (section 1.6.1) and a high residue diet are helpful. In proctitis these measures may supplement treatment with corticosteroids or sulfasalazine (see section 1.5). When necessary, topical preparations containing local anaesthetics (section 1.7.1) or corticosteroids (section 1.7.2) are used, provided perianal thrush has been excluded. Perianal thrush is treated with a topical antifungal preparation (section 13.10.2).

Inoculate portions of soya-bean casein digest medium with a small number (not more than 100 CFU) of the following micro-organisms, using a separate portion of medium for each of the following species of micro-organism Aspergillus niger, Bacillus subtilis, Candida albicans. Incubate for not more than 3 days in the case of bacteria and not more than 5 days in the case of fungi.

Azol1ylmethylketones

Azolylmethyl-ketones of the title structure 4.01 have been claimed as antimycotics for their inhibition of Candida albicans, Trichophyton tonsurans and T rubrum, and as fungicides which control Erysiphe graminis on wheat, E. graminis sp. hordei and tritici on barley, E. cichoracearum on cucumber, Podosphaera leucotricha on apple leaves, Piricularia oryzae on rice plants, Venturia inaequalis and Uncinula necator. 4.001, 4.002, 4.003, 4.004, 4.005, 4.006, 4.007, 4.008, 4.009, 4.010, 4.011, 4.012, 4.013, 4.014, 4.015, 4.016, 4.017, 4.018

Colocalization Of Interacting Gene Pairs On A Genome

If gene clusters are under some functional constraint, the physical links on a genome must have been conserved during evolution. Interestingly, co-expressed gene pairs in S. cerevisiae are conserved in Candida albicans (Huynen et al., 2001 Lercher et al., 2002). In addition, there are fewer breakpoints within co-expressed gene clusters in both human and mouse than expected (Singer et al., 2005). These results indicate that co-expressed gene clusters have been conserved during evolution. Makino and McLysaght examined whether interacting gene clusters on a human genome are conserved in other vertebrate genomes by comparative genomics (Makino & McLysaght, 2008). They investigated both orthologs of genes in each gene cluster and their genomic locations on 13 chordate genomes derived from the Ensembl database. The interacting gene clusters are significantly more conserved across vertebrate genomes than other pairs of genes located within 1 Mbp in the human genome (Makino & McLysaght,...

Azol1yl2hydroxyalkanxones

Title 1-(azol-1-yl)-2-hydroxyalkan-3-ones 4.28 inhibit in vivo dermatophytes, Candida albicans and act as fungicides e.g. against Cochliobolus sativus, and Sphaerotheca fuli-ginea on cucumbers. 4.153, 4.154, 4.155 Thirteen out of 76 of these compounds have demonstrated interesting in vitro antimicrobial activity and excellent therapeutic effect on subacute systemic murine candidiasis. 4.155 After additional tests against guinea pig dermatophy-tosis, compound 4.29 remained as optimum with a demonstrated superiority over ketoconazole.

Azolylalkyl nitriles with further reactive groups on the alkyl

Title compounds 4.66 represent antimycotics with high in vivo activity, after p.o. doses, against systemic Candida albicans and Aspergillus fumigatus infections in mice. Some samples (e. g. R Pr) are comparable with fluconazole. 4.275, 4.276, 4.277, 4.278, 4.279, 4.280, 4.281, 4.282, 4.283, 4.284, 4.285 Another series 4.68, also with high activity against systemic candidiasis in mice, carries two further substituents on the alkyl. 4.287

Role of IDO in the Defense Against Infectious Pathogens

One of the most simple and ancient host defense against pathogens is the depletion of nutrients, such as iron-chelating proteins. The kynurenine pathway, by depleting Trp, can locally impair the growth of microbes. Soon after the discovery of IDO, it was observed that this enzyme is notably induced in mouse lung after an intraperitoneal administration of bacterial LPS 91 , leading to Trp degradation and increased plasma kynurenine levels 92 . IFN-7 inhibits IDO-dependent growth of group B streptococci 93 , intracellular pathogens (e.g., Chlamydia psittaci, Leishmania donovani, and Toxoplasma gondii) 94, 97 , and viruses (e.g., cytomegalovirus or Herpes Simplex Virus) 95, 96 . This effect is mediated by increased Trp degradation, and inhibition could be reversed by the addition of Trp excess. Infection with Candida albicans produces an IFN-7-dependent IDO induction in DCs and polymorphonuclear neutrophils that inhibits fungi growth, and in this case the antioxidant properties of IDO...

Differential Diagnoses

Like AFP and AO, BMS is a diagnosis of exclusion. Burning pain symptoms in the oral mucosa can be caused by systemic or local conditions, including anemia, vitamin B, folic acid, or iron deficiency, untreated diabetes, hormonal disturbances (menopausal complaints, estrogen deficiency), oral candidiasis, hyposalivation, Sjogren's syndrome, oral lichen planus, or systemic lupus.136,142 Furthermore, burning symptoms can be a side effect to some medications such as angiotensin-converting enzyme (ACE) inhibitors and also allergy to dental materials, dentures, toothpaste, etc., must be considered and excluded before a BMS diagnosis can be given.136,142

Azol1ylalkylamines with a further substituent on the alkyl and their derivatives

Most title compounds of the optimal form 5.09 which carry hydroxyl at Ca or Cp and amino at Cg, Cg , have been claimed as antimycotics, showing protective action against a mouse systemic Candida albicans infection. 5.010, 5.041, 5.042, 5.043, 5.044, 5.045, 5.046, 5.047, 5.048, 5.049 Some of these compounds are superior to fluconazole by a factor of 5 to 10. 5.050 The highest activity against systemic Candida infection of mice rests in the (2R,3R)-configuration. 5.051 The (-)-stereomer of 5.10A is superior to fluconazole and equivalent to Sch-42427 in the rat model of vaginal candidiasis. 5.050 The amino nitrogen of the title compounds can also be part of a piperi-dine, 5.052, 5.053 a piperazine, 5.054, 5.055 or a morpholine ring. 5.056 High antimycotic activity against Candida albicans and fungicidal action against Pyre-nophora teres on barley and Uromyces appendiculatus on bean has been demonstrated. Inhibition of tumor cells has also been detected. 5.053 Series 5.14 of the title...

Azol1ylalkylketon2oximes

Title compounds 5.31 have been claimed as bactericides which inhibit Staph. aureus, antimycotics against Candida albicans, and fungicides which control Podosphaera leu-cotricha on apple seedlings, Cercospora spp., and Erysiphe graminis on wheat. 5.146, 5.147, 5.148, 5.149, 5.150, 5.151, 5.152, 5.153, 5.154 Some papers report on variation of R by 5-chlorothienyl-2-methyl and by x-halogen-(benzo b thienyl-2- or 3-methyl- yielding substances 5.32 which inhibit in vitro Candida albicans, Cryptococcus neoformans and Aspergillus spp. 5.155, 5.156

Biochemistry of medically relevant toxins Native toxins

Ricin toxin (RT), the heterodimeric 65 kDa glycoprotein produced in the seeds of castor bean plants or Ricinus communis, is composed of two functionally distinct polypeptides linked by a disulfide bond a 33 kDa B-chain ricin toxin B-chain (RTB) disulfide linked to a 32kDa A-chain ricin toxin A-chain (RTA) . Both chains have a high mannose content, and the A-chain contains fucose (Vitetta et al., 1987). The A- and B-chains of the toxin remain disulfide-bonded, and this bond can be cleaved intracellularly, thereby preserving cytoxicity (Vitetta et al., 1987). Ricin intoxication of eukaryotic cells involves sequentially, (a) RTB binding to -galactosyl pyranoside groups on cell-surface glycoproteins, (b) internalization by endocytosis, (c) transfer to the Golgi, (d) routing to a critical organelle, possibly the endoplasmic reticulum, (e) disulfide bond reduction with release of RTA, (f) translocation of RTA to the cytosol, and (g) catalytic inactivation of protein synthesis. Hence, the...

X1HAzol1ylmethylisoxazolidines and isoxazolines 6121 31HAzol1ylmethylisoxazolidines

In the group of ci's-imidazolylmethyl-derivatives, optimization of R for in vitro activities against Trichophyton rubrum, Candida albicans and especially Aspergillus fumigatus with ketoconazole as standard, substituents n-C6H13, 4-CH3C6H4SCH2-, 6.048 4-ClC6H4-, 4-ClC6H40CH2-, 6.004 and in one case also trans-CH CHC6H5 6.030 have been found optimal. Of aromatic halogen, 2-Cl and 2,6-Cl2 substitution result in similar activity than 4-Cl. Their antifungal activity in vitro against Candida, Aspergillus and dermatophy-tes ranks 6.05A > C > D > ketoconazole > > B (> indicates that activity is better than) however, against two strains of C. albicans causing rat candidial vaginitis, the ranking is ketoconazole > B > D > C > A, which contrasts to the in vivo efficacy of ketoconazole > D > > A. 6.042 While 1,2,4-triazole derivatives have been generally inferior to their imidazole analogs, the in vivo efficacy of B is superior to its imidazole analog A. In using three...

Yeast Copperiron Link

Iron uptake into S. cerevisiae involves several different assimilatory pathways depending on the chemical source of iron and its concentration. In general, all of the pathways require reduction of Fe3+ to Fe2+ by one or more products of the FRE1-FRE7 genes (14,26). Under iron-limiting conditions, high-affinity uptake is mediated by the inducible Fet3p Ftr1p complex in the plasma membrane (1,14,27). Fet3p is a multicopper oxidase (28) whose active sites are related to multicopper oxidases such as laccase, ascorbate oxidase, and ceruloplasmin. Fet3p functions to oxidize Fe2+ to Fe3+ at the cell surface Fe3+ is then delivered from Fet3p to the associated Fe3+ permease, Ftr1p, for transport into the cell (14,27). Highly related pathways operate in other fungi. In Schizosaccharomyces pombe, Frp1 is related to the Fre reductases, and Fio1 Fip1 forms an iron-uptake complex related to Fet3p Ftr1p (29). The fungal pathogen Candida albicans also uses a similar pathway, involving a...

Azol1ylmethyl4benzoyl morpholines and morpholin2ones

Efficacy against the vaginal infection of the rat by Candida albicans, murine coccidiomycosis, histoplasmosis and cryptococcosis has demonstrated superiority of these compounds over fluconazole and itraconazole. However, 6.14 substances lack pronounced activity against murine aspergillosis. 6.057, 6.103 Of two morpholin-2-one analogs 6.15A and B, UR-9728 in spite of little in vitro antifungal activity has demonstrated higher efficacy against experimental systemic candidiasis and C. cryptoformans infection than itraconazole, and similar efficacy than Sch 42427 (see section 3.11.4). 6.104

Genetic Pathways To Improved Drug Therapy

Since human cells and tissues are composed of complex networks comprising redundant, convergent, and divergent signaling pathways, a systems biology framework that entails identification of combinations of small molecules that perturb signaling pathways in desirable ways would appear to offer a reasonable approach to drug discovery. Borisy and colleagues have brought these issues into sharper focus by devising a high-throughput screening method for identifying effective combinations of therapeutic compounds.49 Borisy's method incorporates both an experimental strategy and analytical methods to determine whether a beneficial interaction occurs between compounds. The application of this method to screen approximately 120,000 different two-component combinations of drugs for unexpected synergist interactions attributable to signaling networks within and between cells has yielded some promising results. Among these, they identified (1) a fungistatic (fluconazole) and a urinary analgesic...

X[11HAzol1ylyhydroxy andor ketoalkyl 13dioxacycloalkanes and derivatives

The cis form of a compound with biphenyl for Rs and C6H4COOCH2- as 4-sub-stituent shows superior in vitro inhibition of Candida albicans compared with bifonazole and ketoconazole. 6.128 Isomeric structures with biphenyl R' provided development candidates 6.20A, R-31000 59364-79-3 and doconazole. 6.080

Thioanalogs of x1Hazol1ylalkyl dioxacycloalkanes and their derivatives

4-(1H-Azol-1-yl)methyl-1,3-oxathianes like 6.28 or -oxathiolanes show superior efficacy in the Candida albicans-infected mouse model. 6.153 2-(1H-Triazol-1-yl)methyl-1,4-oxathiane 6.29 displays better efficacy against systemic candidiasis in mice than fluconazole. 6.103, 6.154

Atrophy - topical estrogen vaginal cream, oral hormone replacement therapy Diet modification Low-oxalate diet with calcium citrate 400 mg p.o. t.i.d.

Electron Transport In Other Organisms

Generalizations about yeasts should be taken with a grain of salt there are many different species of yeasts, and some of them do appear to have a conventional complex I . The identification is based on several criteria. The detection of rotenone-sen-sitivity is suggestive the isolation of large complexes ( 700 kDa) is more convincing. Finally, sequencing the mitochondrial DNAs from several of these species has revealed the presence of ORFs with obvious homology to the mitochondrial genes for complex I (ND1, ND2, , ND6, ) found in many organisms. A subdivision of yeast species into strictly aerobic yeasts and facultatively fermenting yeasts may relate to the capacity for complex I formation. The presence of a complex I-like activity has so far been deduced for the yeasts Candida pinus, Cryptococcus albidud, Rhodotorula minuta, Trichosporon beigelii, Candida parapsilosis, Pichia guilliermondii, Clavis-pora lusitaniae, Hansenulapolymorpha, and others 122,123 .

Itraconazole Resistance safety and side effects

This has given rise to a pessimistic view on long-term azole therapy of muscosal candidiasis for these patients. 6.304 Immunocompromized cancer and transplantation patients can be protected from fungal infection by itracona-zole. 6.305, 6.306 In the clinical trials discussed above, 2 3.5 of the patients report minor side effects such as nausea, pyrosis, mild gastrointestinal intolerance and headache in the treatment of skin dermatoses, pytriasis versicolor and vaginal candidiasis. Their incidence increases to about 8 in the treatment of systemic mycoses, caused by longer treatment, by the character of the disease, and by elevated liver enzymes. 6.274, 6.313

AaDisubstituted 12hydroxyalkyl1Hazoles

A QSAR study has been reported of 2-alkyl, -alkenyl, and 1-imidazole with antifungal activity against Candida spp., Aspergillus, and dermatophytes at ideal lipohilicities (log P0) for each group of fungi. 3.060 This is interpreted as a consequence of membrane perturbation of the fungus by the ionized and or non-ionized imidazole compound, possibly via inhibition of membrane-bound enzymes. Compound 3.16A displays good activity against A. fumigatus and is more effective than fluconazole against systemic candidiasis in mice. 3.072, 3.073, 3.074 Further compounds 3.13 with R halogenoalkyl inhibit Candida infection in mice, protect wheat against Puzinia graminis, and control Piricularia oryccae and Erysiphe graminis hordei on barley. 3.080, 3.081, 3.082, 3.083, 3.084 Other substances 3.13 with R cyclopropylalkyl or halogenocyclopropyl also inhibit Candida albicans infection in mice. 3.085,3.086,3.087 Their control of Erysiphe graminis tritici on wheat is enhanced by alkoxylates....

Biological Activity Glycolipids

Glycolipids are the most common group of biosurfactants of which the most effective regarding surface active properties are the trehalose lipids obtained from Mycobacterium and related bacteria, the rhamnolipids obtained from Pseudomonas sp. and the sophorolipids obtained from yeasts. Otto and coworkers12 described the production of sophorose lipids using deproteinized whey concentrate as substrate by a two-stage process. Several antimicrobial, immunological and neurological properties have been attributed to mannosylerythritol lipid (MEL), a yeast glycolipid biosurfactant, produced from vegetable oils by Candida strains.62,84 Kitamoto et al53 showed that MEL exhibits antimicrobial activity particularly against Gram-positive bacteria. Isoda et al54 investigated the biological activities of seven extracellular microbial glycolipids including MEL-A, MEL-B, polyol lipid, rhamnolipid, sophorose lipid and succinoyl trehalose lipid STL-1 and STL-3. Except for rhamnolipid, all the other...

O Cationic Surfactants

How Surfactants Work

tolyl oxy ethoxy ethyl ammonium chloride (Diaparene) is a mixture of methylated derivatives of methylbenzethonium chloride. It is used specifically for the treatment of diaper rash in infants, caused by the yeast Candida albicans, which produces ammonia. The agent is also used as a general antiseptic. Its properties are virtually identical to those of ben-zethonium chloride.

Immunomodulatory Activity of Fungal Algae and Lichenderived Polysaccharides

Complement Receptor Neutrophil

Among the group of botanical polysaccharides, fungal-derived polysaccharides are the best-known and one of the most powerful immune stimulants. The reason may be that these types of polysaccharides are also constituents of cell walls of certain pathogenic microorganisms such as Pneumocystis carinii, Cryptococcus neoformans, Aspergillus fumigatus, Histoplasma capsulatum and Candida albicans. It has recently been recognised that the initial interaction between fungi and the innate immune system is via binding between fungal-specific chemical signatures and pattern recognition receptors on mononuclear phagocytes. Fungal pattern-associated molecular patterns are restricted to complex carbohydrates in the cell wall, including phospholipomannan, P-glucans and chitin. These patterns bind specifically to two classes of pattern recognition receptors in phagocyte membranes, Toll-like receptors (TLR) and C-lectin-like receptors, through which they initiate signalling responses that culminate in...

Echinocanadins And Pneumocanadins

LY 303366 is a pentyloxyterphenyl side chain derivative of echinocanadin B that was discovered at Eli Lilly. It was licensed for parenteral use in 2000. Studies have shown that the MICs of LY 303366 against Candida spp. range from 0.08 to 5.12 g mL, and similar activity was obtained against Aspergillus spp. Studies show highly potent activity of the compound in animal models of disseminated candidiasis, pulmonary aspergillosis, and esophageal candidiasis. demonstrate good in vitro and in vivo activity against Candida spp. and c. neoformans clinical isolates.

Identification and Characterization of FET3

Other yeasts, aside from S. pombe and S. cerevisiae, show an oxidase permease-based iron-transport system. A ferroxidase was shown to be essential for iron transport in Candida albicans as deletion of the C. albicans FET3 prevents high-affinity iron transport (26,27). In one study, it was reported that the C. albicansfet3-deletion strain grew poorly in infected mice, suggesting that the FET3 gene may be a virulence factor (27). It is curious that the C. albicans FET3 when expressed in a S. cerevisiaefet3-deletion strain complements the low-iron growth defect (26). This result suggests that C. abicans Fet3p can form a complex with S. cerevisiae Ftrlp, whereas the FET3 homolog of S. pombe, fio1+, cannot. Biochemical studies have shown that P. pastoris also expresses a ferroxidase similar Fet3p (19). It may well be that a ferroxidase permease iron-transport system is common among yeasts.

Why C-6 Deoxy Tetracyclines Are More Stable

The tetracyclines have the broadest spectrum of activity of any known antibacterial agents. They are active against a wide range of Gram-positive and Gram-negative bacteria, spirochetes, mycoplasma, rickettsiae, and chlamydiae. Their potential indications are, therefore, numerous. Their bacterio-static action, however, is a disadvantage in the treatment of life-threatening infections such as septicemia, endocarditis, and meningitis the aminoglycosides and or cephalosporins usually are preferred for Gram-negative and the penicillins for Gram-positive infections. Because of incomplete absorption and their effectiveness against the natural bacterial flora of the intestine, tetracyclines may induce superinfections caused by the pathogenic yeast Candida albicans. Resistance to tetracyclines among both Gram-positive and Gram-negative bacteria is relatively common. Superinfections caused by resistant S. aureus and P. aeruginosa have resulted from the use of these agents over time. Parenteral...

Azol1ylalkanealdehyde orketon oximes with further substituents on the alkyl

A methoxymethyl-oxim ether 5.40B is superior to fluconazole after p.o. administration to infected mice by a factor of ca. 12 against Candida albicans and of > 3.3 against Aspergillus fumigatus. 5.179 in the Candida albicans infection model of the mouse, though the plasma half-life is only 2 hours. 5.182, 5.183, 5.184 These appear superior to fluconazole and itraconazole against systemic asper-gillosis in mice and vaginal candidiasis in immunosuppressed mice.

Dynamic Resolution Processes

The integration of a catalyzed kinetic enantiomer resolution and concurrent racemization is known as a dynamic kinetic resolution (DKR). This asymmetric transformation can provide a theoretical 100 yield without any requirement for enantiomer separation. Enzymes have been used most commonly as the resolving catalysts and precious metals as the racemizing catalysts. Most examples involve racemic secondary alcohols, but an increasing number of chiral amine enzyme DKRs are being reported. Reetz, in 1996, first reported the DKR of rac-2-methylbenzylamine using Candida antarctica lipase B and vinyl acetate with palladium on carbon as the racemization catalyst 20 . The reaction was carried out at 50 C over 8 days to give the (S)-amide in 99 ee and 64 yield. Rather surpris-

Heteroarylmethyl and heteroarylmethylenazoles

3-(1H-Imidazolylmethyl)-indoles 2.24 inhibit Cryptococcus neoformans (the cause of fatal meningitis in humans) and Candida pseudotropicalis. 2.130, 2.131 inhibit C. albicans, C. tropicalis and C. stellastoida, and vaginal yeast infection of hamsters. 2.132, 2.133, 2.135, 2.161 Optimal compounds 2.25 with Az Im W, Y, Z H X Cl have been compared with rotamer forms of miconazole. 2.134 2.26A and 2.26B constitute a new class of azolyl fungicides, with main activity against Cryptococcus neoformans, and some also against Candida pseudotropicalis and Geotrichum candi-dum. 2.135, 2.136, 2.137, 2.138, 2.139, 2.140, 2.141 zole is superior to a similar preparation of miconazole in hamsters suffering from vaginal Candida albicans infection. 2.142 shows remarkable activity against Candida krusei. 2.143

Hydroxy3thioalkyl1Hazole derivatives

SM-4470 is endowed with very high antifungal activity. It is twice as active as ketoconazole in the p.o. treatment of systemic candidal infection in mice. 3.910 Its efficacy in curing candidal vaginitis compared with ketoconazole is twice that in mice and equal to that in rats and guinea pigs. The preparation of 3.115A, genaconazole 120924-80-3 and closely related compounds is subject of numerous applications and papers. 3.911, 3.912, 3.913, 3.914, 3.915, 3.916, 3.917, 3.918, 3.919, 3.920, 3.921 14C-Labeled genaconazole has also been synthesized. 3.922 Special efforts have been directed to receive pure enantiomers. 3.906, 3.909, 3.914, 3.915, 3.916, 3.918, 3.919, 3.920, 3.923, 3.924, 3.925, 3.926, 3.927, 3.928 The in vitro activity of the (2R,3R)-enantiomer Sch-42427,115B 121650-83-7 against Candida albicans is larger by a factor of 500 and against A. fumigatus by a factor of ca. 130 than that of the (2S,3S)-enantiomer. 3.921, 3.929 The superiority of Sch-42427 in the prophylactic...

Azol1ylalkylketon hydrazones and semicarbazones

Title compounds 5.42 with Az pyrrol-1-yl, have been disclosed as antimycotics with in vitro inhibition of a large group of Candida spp. 5.192 The antifungal activities of the (E)- and (Z)-stereomers are quite similar. 5.195, 5.196 Control of the Candida albicans infection of the mouse after oral doses surpasses that of ketoconazole.

Alkenyl and alkinyl1Hazoles and their halogen derivatives

In general, Z-isomers are more potent against Candida and E-isomers more active against Trichophyton rubrum, but agent GBR-14206, 2.36A 123414-70-0 stands out with optimum activities against both species. 2.238 An injectable emulsion of 2.36B has been sucessful in the treatment of mice infected with Candida albicans. 2.239 The hydrochloride of its monochlorderi-vate 88607-90-3 inhibits Drechslera sorokiniana on barley seeds. 2.240) The medicinal chemistry of compounds 2.38 is covered by a full paper. 2.267 Optimal substituents against Trichophyton mentagrophytes, T. rubrum and Candida albicans are R, R' H, Me R C6H5CH2, 4-ClC6H4CH2, 3-ClC6H4CH2, 3,4-Cl2C6H5CH2, and 2-Chlorthienyl-3-methyl- and R' H, 5-Cl, and 3,5-Cl2. Replacing imidazole by 1,2,4-triazole lowers antimicrobial activity. The same group of compounds has been investigated by computer automated structure correlations (CASE) and QSA methods. Good correlations have been achieved for activities against Candida albicans and...

Mannosylerythritol Lipids

This glycolipid biosurfactant consists of a sugar called mannosylerythritol and are synthesized by yeast like Candida antarctica24,25 and Candida sp. SY 16.26 The fatty acid component of bio-surfactant was determined to be hexanoic, dodecanoic, tetradecanoic or tetradecenoic acids.26 Mannosylerythritol lipids synthesized by Candida sp. SY 1626 lowered the surface tension of

Structure Of Zygmosterol

Purine And Pyrimidine Structure

Additional imidazoles have since been introduced into clinical use (Fig. 7-10). Butaconazole has been marketed primarily in vulvovaginal anticandidal cream. Tioconazole, where the benzylic phenyl ring has been isosterically exchanged with chlorinated thiophene, has been introduced as a topical product (England) against Candida and dermatophytes bifonazole has been marketed in Germany for several years against topical dermatophyte infections including tinea versicolor. Its structure is not only simpler than most active imidazoles, but it is also unique as it is devoid of any aryl halogen atoms (Fig. 7-10). Although also a relatively simple-structured imidazole drug, clocanazole nevertheless seems to have the necessary features for treatment of topical human dermatomycoses. Fluconazole has the unique structural features of triazole rings (instead of imidazole) and predictably effectiveness-enhancing fluorine atoms on the only benzene ring in the molecule. It is currently utilized in...

Amyotrophic Lateral Sclerosis

Sod1 Regulation Mrna

A role for Cu,Zn-SOD in the free-radical theory of senescence was provided by the shortened lifespan of Drosophila with a mutational defect in Cu,Zn-SOD, and by Candida elegans, which had only half the normal complement of SOD (142,143). Mice lacking SOD exhibited a shortened life-span (144) but appeared normal while young and were less able to recover from axonal injury (133). A lack of Mn-SOD imposed more serious consequences by shortening the life-span and exhibiting faulty mitochondrial activities in several tissues, especially the heart (145,146). Thus, Mn-SOD may play a more critical role than Cu,Zn-SOD in antioxidant defense mechanisms under normal physiological conditions (147). This is supported by the findings that mice lacking Mn-SOD die at very young age (145,146).

Azolyl1hydroxyalkan2one ethers 4511 11HImidazolylphenoxyalkan2ones

Climbazole inhibits Aspergillus, Penicillium, Candida and Poecilomyces fungi on household apparel, which recommends its use as household fungicide. 4.115 It is also useful as a component part of anti-dandruff shampoos, 4.116 and in dental mouthwashes to combat gingivitis and periodontitis. 4.117

Azol1ylalkylnitriles

Some nitriles are part of the claims for the corresponding carboxylic acid derivatives in section 4.11.1. Trimellitic acid salts of the title compounds have been prepared. 4.220, 4.228 These nitriles, after p.o. doses, protect mice infected with Candida albicans. They also control Puccinia recondita and Erysiphe graminis on wheat seeds, Pyri-

Examples where introduction of ferrocene has resulted in a loss or no change in activity

The 2,4-diflurophenyl ring of fluconazole is replaced by a ferrocene ring in the ferrocene-fluconazole analogue 4.22 The replacement was expected to enhance the permeability of 4 into Candida (yeast) cells. In this case, a role was hypothesized for the metal ion. Reports have shown that the growth of Candida is dependent on iron iron deprivation suppressed growth while iron overload had the opposite effect. However, fluconazole showed an increase in its candidacidal activity in the presence of an iron overload.23 This led to the hypothesis that the inclusion of iron (in the form of ferrocene) in the flucona-zole molecule might be an effective way of enhancing its activity against clinically important resistant Candida species. This was not found to be the case. When evaluated in vitro against several species, the ferrocene analogue actually promoted the growth of Candida. When given in a 1 1 combination with fluconazole, the anti-candidacidal activity of the latter was suppressed. The...

Diphenylmethyl1Himidazoles

Compound 2.48 which is not only related to bifonazole, but also to naftifine, shows high activity against Candida strains. 2.303 For the indications given above, formulation is very important for bifonazole and lombazole. 2.319, 2.320, 2.321, 2.322, 2.323, 2.324, 2.325, 2.326, 2.327, 2.328, 2.329, 2.330 Bifonazole is characterized by a rather low solubility in water compared to other standard azole antimycotics. On complexing with b-cyclodextrin, solubility increases about 160-fold. Though the resultant complex appears to have lost activity against the common test organisms, addition of b-cyclodextrin to the aqueous phase of a galenic preparation (especially one with carbapol 1 ), increases the inhibition zone size 2-to3-fold for Candida albicans, A. niger, S. cerevisiae and T. cutaneum. It seems that addition of the dextrin may result in a better release of the drug from its preparations. 2.331 The best example (Az Im, n 1, R, R', R Cl R Cl, R' CH3) displays activity against Candida...

Aryloxyalkyloxy1alkenyl1Hazoles

Title compounds, which might also be regarded as 2-(1H-azol-1-yl)vinyl-ethers, have been discovered by first extending the -OCH2- substructure of econazole 3.48A to -X(CH2)n X'- with X, X' O, S and n 1 to 4, hoping to increase solubility in water. The first series of products culminated in a substance 3.79 with higher i.v. antimycotic activity than the standard, much lower toxicity in mice, and better curative action in the treatment of vaginal candidiasis in rats. 3.636 The (Z)-stereostructure of omoconazole has been confirmed by NMR and X-ray analysis. 3.641 The corresponding (E)-isomer shows a much lower antimyco-tic potency and a much higher toxicity. The drug displays superior in vitro activity against C. albicans, C. neoformans, Torulopsis candida, Trichophyton mentagrophytes and A. fumigatus compared with that of democonazole (see below) and 3.79. In its action against A. fumigatus, pronounced superiority to miconazole and ketoconazole has been demonstrated. 3.642 Omoconazole...

Itraconazole Preclinical and clinical results

In vitro and in vivo antifungal activities of itraconazole are poorly correlated. In a series of 36 related compounds, in vivo tests with ketoconazole as standard show six substances clearly superior against vaginal candidiasis in rats, and eight substances clearly superior against microsporosis in guinea pigs. 6.220 Itraconazole has been compared systematically with ketoconazole. 6.252 In vitro superiority of itraconazole against fluconazole-resistant isolates of Candida spp. and clinical isolates from patients with pulmonary aspergillosis have been demonstrated recently, 6.255, 6.256 as well as against many experimental mycoses. 6.257, 6.258 Itraconazole is 100-fold more active against Aspergillus strains, 6.259, 6.260 and 10-fold more active against Pityrosporum ovale than ketoconazole. 6.261 extremely well. 6.274, 6.275, 6.276, 6.277, 6.278, 6.314 For the invasive form, itraconazole is a useful alternative for amphotericin B. 6.279, 6.280 Chronic, endocardial and cerebral forms...

Biomedical and Therapeutic Applications of Biosurfactants

As discussed above a broad range of chemical structures have been attributed to biosurfactants.1-2,4-5 Some of these biosurfactants were described for their potential as biological active compounds and applicability in the medical field. Therefore, they are a suitable alternative to synthetic medicines and antimicrobial agents and may be used as safe and effective therapeutic agents.21,25 Recently, there has been an increasing interest in the effect of biosurfactants on human and animal cells and cell lines.28,42,83 Lipopeptides produced by Bacillus subtilis36 and Bacillus licheniformis,19,49-51 mannosylerythritol lipids produced by Candida antartica53 and rhamnolipids produced by Pseudomonas aeruginosa,33-34 have been shown to have antimicrobial activities.

Azolylalkenyl nitriles with N and Ssubstituents on the alkenyl

Lanoconazole is qualified as outstanding inhibitor of Trichophyton spp., Aspergillus spp., Penicillium spp., Malassezia furfur and M. pachydermatis and Tinea versicolor with superiority to bifonazole. It shows a high curative effect against tinea corporis and tinea pedis. 4.305 Secondary resistance is not easily developed by dermatophytes. 4.310 Recent clinical isolates and stock cultures of Candida albicans have the same sensitivity against lanconazole. 4.311

Azolylalkyl carboxylic acids esters and amides with one or two further substituents on the alkyl

Title compounds 4.63 have been claimed as antimycotics, which protect mice against the lethality of Candida albicans infection, and fungicides and also show plant growth control. 4.256, 4.269, 4.270, 4.271, 4.272 In these series, compound 4.64, UK 51,486 has been discussed in a study to elucidate the problematic correlation between in vitro potency and in vivo efficacy of antimycotics. This agent resembles fluconazole more closely than ketoconazole in MIC values, pharmacokinetics, and efficacy in vaginal and systemic candidiasis models. 4.271, 4.273

AAzol1ylmethylallylalcohols and their derivatives

These have been claimed as medicinal and agricultural antifungals. 3.709, 3.710, 3.711, 3.712, 3.713, 3.714, 3.715, 3.716, 3.717, 3.718, 3.719, 3.720, 3.721, 3.722, 3.723, 3.726b Some of these compounds show a high in vivo activity against Candida albicans, Aspergillus niger and A. fumigatus infections of When given p.o., both substances are active against Aspergillus and Candida infections in animals. DuP-860, in comparison with itraconazole and fluconazole, generally shows superior activity in vitro against Candida albicans, C. tropicalis, C. parapsilosis, C. lusitaniae, C. guilliermondi, C. glabrata, Cryptococcus neoformans, and Aspergillus spp. Pharmacokinetic characteristics include moderate t1 2 values in experimental animals compared with those of fluconazole. 3.724 DuP 860 has been discontinued from active development. 3.726

Oral sideeffects of drugs

The oral mucosa is particularly vulnerable to ulceration in patients treated with cytotoxic drugs, e.g. metho-trexate. Other drugs capable of causing oral ulceration include captopril (and other ACE inhibitors), gold, nicorandil, NSAIDs, pancreatin, penicillamine, pro-guanil, and protease inhibitors. Erythema multiforme or Stevens-Johnson syndrome may follow the use of a wide range of drugs including antibacterials, antiretrovirals, sulfonamide derivatives, and anticonvulsants the oral mucosa may be extensively ulcerated, with characteristic target lesions on the skin. Oral lesions of toxic epidermal necrolysis have been reported with a similar range of drugs. Lichenoid eruptions are associated with ACE inhibitors, NSAIDs, methyldopa, chloroquine, oral anti-diabetics, thiazide diuretics, and gold. Candidiasis can complicate treatment with antibac-terials and immunosuppressants and is an occasional side-effect of corticosteroid inhalers, see also p. 185.

Aryl1Hazoles

1-(2-Hydroxyphenyl)-pyrroles are potent inhibitors of Candida albicans, Cryp-tococcus neoformans and Aspergillus fumigatus. 2.061 1-Phenylimidazole hydrochloride is devoid of antibacterial activity. 2.064 1-Carboxyalkylphenyl-imidazole-3-oxides have antiviral activities. 2.065 1,4-Diphenyl-imidazoles 2.08 show activity against a large number of Candida albicans strains. 2.066, 2.067 has high activity against a number of Candida albicans strains and Gram-negative bacteria. 2.068

Defective medicines

The most common effect that drugs have on the salivary glands is to reduce flow (xerostomia). Patients with a persistently dry mouth may have poor oral hygiene they are at an increased risk of dental caries and oral infections (particularly candidiasis). Many drugs have been implicated in xerostomia, particularly antimuscarinics (anticholinergics), antidepressants (including tricyclic antidepressants, and selective serotonin re-uptake inhibitors), alpha-blockers, antihistamines, antipsy-chotics, baclofen, bupropion, clonidine, 5HT, agonists, opioids, and tizanidine. Excessive use of diuretics can also result in xerostomia. Some drugs (e.g. clozapine, neostigmine) can increase saliva production but this is rarely a problem unless the patient has associated difficulty in swallowing.

Test Organisms

Use cultures of the following microorganisms1 Candida albicans (ATCC No. 10231), Aspergillus niger (ATCC No. 16404), Escherichia coli (ATCC No. 8739), Pseudomonas aeruginosa (ATCC No. 9027), and Staphylococcus aureus (ATCC No. 6538). The viable microorganisms used in the test must not be more than five passages removed from the original ATCC culture. For purposes of the test, one passage is defined as the transfer of organisms from an established culture to fresh medium. All transfers are counted. In the case of organisms maintained by seed-lot techniques, each cycle of freezing, thawing, and revival in fresh medium is taken as one transfer. A seed-stock technique should be used for long-term storage of cultures. Cultures received from the ATCC should be resuscitated according to directions. If grown in broth, the cells are pelleted by centrifugation. Resuspend in 1 20th the volume of fresh maintenance broth, and add an equal volume of 20 (v v in water) sterile glycerol. Cells grown...

Bromoditerpenes

Diethyl ether extracts of seaweeds Cystoseira mediterranea, Entero-morpha linza, Ulva rigida, Gracilaria gracilis, and Ectocarpus siliculosus are isolated from the Urla coast (Turkey showed effective results against all test organisms such as Candida sp., Enterococcus faecalis, S. aureus, Streptococcus epidermidis, Pseudomonas aeruginosa, and Escherichia coli). Fresh weights of algal extracted using the diethyl ether showed the strong broad spectrum antibiotic activity against the tested bacterial strains moreover they have shown the more activity against the Gram positive, which was more when compared to the Gram-negative bacteria (Tuney et al., 2006).

Sterility

Inoculate portions of Alternative Fluid Thioglycollate Medium with a small number (not more than 100 cfu) of Clostridium sporogenes.4- Inoculate portions of Soybean-Casein Digest Medium with a small number (not more than 100 cfu) of the following microorganisms, using a separate portion of medium for each of the following species of microorganism Aspergillus niger, Bacillus subtilis, and Candida albicans. Incubate for not more than 3 days in the case of bacteria and not more than 5 days in the case of fungi.

Therapeutic Uses

The usual dose of C-AMB is 0.5-0.6 mg kg, administered in 5 glucose over 4 hours. Candida esophagitis in adults responds to 0.15-0.2 mg kg daily. Rapidly progressive mucormycosis or invasive aspergillosis is treated with doses of 1-1.2 mg kg daily until progression is arrested. ABCD is approved for patients with invasive aspergillosis who are not responding to or are unable to tolerate C-AMB. Ambisome is approved for empiric therapy of neutopenic patients not responding to appropriate antibacterial agents and for salvage therapy of aspergillosis, cryptococcosis, and candidiasis. ABLC is approved for salvage therapy of deep mycoses.

Flucytosine

Resistance arising during therapy (secondary resistance) is an important cause of therapeutic failure when flucytosine is used alone for cryptococcosis and candidiasis it can result from loss of the permease necessary for cytosine transport or decreased activity of UPRTase or cytosine deaminase (Figure 48-2).

Vaginal Application

Vaginal creams, suppositories, and tablets for vaginal candidiasis are all used once daily for 1-7 days, preferably at bedtime to facilitate retention. None is useful in trichomoniasis. Most vaginal creams are administered in 5-g amounts. Three vaginal formulations clotrimazole tablets, miconazole suppositories, and terconazole cream come in both low- and high-dose preparations. A shorter duration of therapy is recommended for the higher doses. These preparations are administered for 3-7 days. Approximately 3-10 of the vaginal dose is absorbed. Although some imidazoles are teratogenic in rodents, no teratogenic effects in humans have been attributed to the vaginal use of imidazoles or triazoles. The most common side effect is vaginal burning or itching. A male sexual partner may experience mild penile irritation. Cross-allergenicity among these compounds is presumed to exist.

Examination

Vaginal pH, whiff test, and microscopic examination of vaginal secretions with potassium hydroxide (KOH) and normal saline can help evaluate for vaginitis and estrogen deficiency. Vaginal fluid may be cultured for Candida (as microscopic evaluation may reveal can-didias is in only 50 percent of cases).192 Acetowhite changes or lesions should be biopsied to evaluate for an underlying dermatosis or infectious or neoplastic process.

Oral Ulcers

Ulcers in the mouth can be a cause of severe recurrent pain. The various ulcers can be grouped as recurrent oral aphthae, acute herpetic gingival stomatitis, acute candidiasis, and acute necrotizing ulcerative gingivitis. Aphthous ulcer is recurrent, stress induced, and painful. Diagnosis is clinical. A large aphthous ulcer is designated a major aphthous and heals by scarring.

Toxicology

Infectious diseases of the skin, eyelids, conjunctivae, and lacrimal excretory system are encountered regularly in clinical practice. Periocular skin infections are divided into preseptal and post-septal or orbital cellulitis. Depending on the clinical setting (i.e., preceding trauma, sinusitis, age of patient, relative immunocompromised state), oral or parenteral antibiotics are administered. Dacryoadenitis, an infection of the lacrimal gland, is most common in children and young adults. It may be bacterial (typically Staphylococcus aureus, Streptococcus species) or viral (most commonly seen in mumps, infectious mononucleosis, influenza, and herpes zoster). In infants and children, the disease usually is unilateral and secondary to an obstruction of the nasolacrimal duct. In adults, dacryocystitis and canalicular infections may be caused by S. aureus, Streptococcus species, Diphtheroids, Candida species, and Actinomyces israelii. Any discharge from the lacrimal sac should be sent for...

Aspects

Good absorption of an oral dose of ketoconazole requires sufficiently low gastric pH to dissolve in the gastric juice, 6.341 though in vitro the disintegration time of ketoconazole tablets does not change between pH 2 and pH 6. 6.342 An acidic beverage, like Coca-Cola, significantly increases the absorption of the drug. 6.343 Suprisingly, optimal cellular uptake of ketoconazole by Candida albicans occurs

Antifungals

Screening a peptide collection against Candida albicans (Ca) and Cryptococcus neoformansa (Cn), the hexapeptide His-D-Trp-D-Phe-Phe-D-Phe-Lys-NH2 (compound 8) was identified as a hit with IC50 29.6 pM and MIC 6.81 pM, respectively. For this study it was decided to keep the D-amino acids at their original positions (2, 3, and 5) vary only the remaining 1, 4, and 6 positions pool the libraries and screen them as mixtures (9).

Amphotericin B

The oral suspension is intended for the treatment of oral and pharyngeal candidiasis. The patient should swish the suspension in his or her mouth and swallow it. The suspension has a very bad taste, so compliance may be a problem. A slowly developing resistance to amphotericin B has been described. This is believed to relate to alterations in the fungal cell membrane. Nystatin is not absorbed systemically when administered by the oral route. It is nearly insoluble under all conditions. It is also too toxic to be administered parenterally. Hence, it is used only as a topical agent. Nystatin is a valuable agent for the treatment of local and gastrointestinal monilial infections caused by C. albicans and other Candida species. For the treatment of cutaneous and mucocutaneous candidiasis, it is supplied as a cream, an ointment, and a powder. Vaginal tablets are available for the control of vaginal candidiasis. Oral tablets and troches are used in the treatment of...

Azoles

Such antifungal compounds, with Ar1 pyrrol-3-yl, 2.53 have been found to be as potent as ketoconazole, and half as potent as bifonazole against Candida albi-cans. 2.337 With Ar2 thienyl, derivatives 2.54A and 5.54B have been claimed as useful antimycotics with demonstrated in vitro inhibition of Candida albicans comparable to the standards. 2.341 From these series, optimal compounds becliconazole 2.56A, 112893-26-3 and agent 2.56B 111790-32-0 display pronounced in vitro antifungal activity against Candida, Trichophyton, and Microsporum genera and against non-dermatophytes like Aspergillus and Penicillium spp. their toxicity to Torulopsis glabrata, Rhodo-torula spp. and Cryptococcus neoformans surpasses that of the standards. 2.351, 2.352 Finally, compounds 2.52 with Ar2 isoquinol-1-yl have resulted in an optimal example with a 4-benzylphenyl for Ar1, displaying half the activity of the standards against Candida albicans strains. 2.357 Replacing phenyl B by pyrrol-3-yl, with phenyl C...

Related structures include compounds 2.17 with good activities against Streptococcus faecalis, Trichophyton mentagrophytes, Aspergillus niger, Candida albicans and Microsporum lanosum. 2.107 In a series of 1-(x-benzylamino- and benzylidenamino)benzyl-imidazoles 2.18, the nitro-substituent has proved optimal for activity against a large number of Candida strains. 2.108, 2.109 Triazolylmethyl-benzeneamines inhibit Aspergillus flavus, A. parasiticus and Fusarium solani, 2.121 but show low activity against Candida albicans, Penicil-lum spp. and Microsporum gypseum when compared to their imidazole analogs 2.18. Degradation in soil of 1-benzyl-1,2,4-triazoles has been investigated for similar compounds with F, Cl, CF3, methoxy and butyl as aromatic substituents. Decomposition increases with moisture and temperature as expected, and is fastest without an aromatic substituent. 2.122 Compounds 2.21 show virucidal activity. 2.123

Polyenes

The polyenes have no activity against bacteria, rickettsia, or viruses, but they are highly potent, broad-spectrum anti-fungal agents. They do have activity against certain protozoa, such as Leishmania spp. They are effective against pathogenic yeasts, molds, and dermatophytes. Low concentrations of the polyenes in vitro will inhibit Candida spp., Coccidioides immitis, Cryptococcus neoformans, H. capsu-latum, Blastomyces dermatitidis, Mucor mucedo, Aspergillus fumigatus, Cephalosporium spp., and Fusarium spp.

Trityl1Himidazoles

It combines good skin penetration with broad-spectrum activity against dermatophytes, yeasts, 2.367 Aspergillus, Malassezia furfur, and inhibits Corynebacte-rium minutissimum, Staphylococci, Streptococci which all may accompany myco-tic infections. In the treatment of tinea infections and cutaneous candidiasis of skin and mucous membranes such as vaginal candidiasis, clotrimazole can be used as a single dose. 2.366 An account of the investigators has summarized the ideas and hypotheses along which optimization of structure was achived. 2.318 Curing rates of Candida infection of the mouse after systemic application are connected with

O Antifungal Agents

The discovery that some infectious diseases could be attributed to fungi actually preceded the pioneering work of Pasteur and Koch with pathogenic bacteria by several years. Two microbiologists, Schonlein and Gruby, studied the fungus Trichophyton schoenleinii in 1839. In that same year, Langenbeck reported the yeastlike microorganism responsible for thrush (C. albicans). Gruby isolated the fungus responsible for favus on potato slices, rubbed it on the head of a child, and produced the disease. Hence, he fulfilled Koch's postulates 40 years before they were formulated.17 In spite of its earlier beginnings, medical mycology was quickly overshadowed by bacteriology, and it has only recently begun to receive the serious attention that it deserves. This is perhaps attributable to the relatively benign nature of the common mycoses, the rarity of the most serious ones, and the need for a morphological basis for differential identification of these structurally complex forms. seated...

Nystatin

Nystatin (mycostatin, nilstat, others) is used only for candidiasis and is supplied in preparations intended for cutaneous, vaginal, or oral administration for this purpose. infections of the nails and hyperkeratinized or crusted skin lesions do not respond. Topical preparations include ointments, creams, and powders, each containing 100,000 units per gram. Powders are preferred for moist lesions and are applied two or three times a day. imadazoles or triazoles are more effective agents than nystatin for vaginal candidiasis. An oral suspension that contains 100,000 units per mL of nystatin is given four times a day. Premature and low-birth-weight neonates should receive 1 mL of this preparation, infants 2 mL, and children or adults 4-6 mL per dose. Older children and adults should be instructed to swish the drug around the mouth and then swallow. Nystatin suspension is usually effective for oral can-didiasis of the immunocompetent host. Other than the bitter taste and occasional...

Terconazole

Its mechanism of action is similar to that of the imidazoles. The 80-mg vaginal suppository is inserted at bedtime for 3 days, while the 0.4 vaginal cream is used for 7 days and the 0.8 cream for 3 days. Clinical efficacy and patient acceptance of both preparations are at least as good as for clotrimazole in patients with vaginal candidiasis. Tioconazole (vagistat 1, others) is an imidazole that is marketed for treatment of Candida vulvovaginitis. A single 4.6-g dose of ointment (300 mg) is given at bedtime. Ciclopirox olamine (loprox) has broad-spectrum antifungal activity. It is fungicidal to C. albicans, E. floccosum, M. canis, T. mentagrophytes, and T. rubrum. It also inhibits the growth of Malassezia furfur. After application to the skin, it penetrates through the epidermis into the dermis, but even under occlusion, < 1.5 is absorbed into the systemic circulation. Because the t122 is short, 1.7 hours, no systemic accumulation occurs. The drug penetrates into hair follicles and...

Antifungal Agents

Fungal and yeast infections in man occur mostly on the skin. A few serious infections occur internally such as Aspergillosis in the lung (farmer's lung) and oral thrush and vaginitis, which are caused by a yeast Candida albicans. Fungal infections of the skin include athlete's foot, infections of the nails and ringworm in the scalp, which arise from Microsporum and Trichophyton species. Some fungi are serious plant pathogens and spoilage organisms on foodstuffs. Apart from the damage that they do to the plant, some of their metabolites, for example, the aflatoxins and the trichothecenes, are the cause of serious diseases in man.
