Physical Properties and Characterization

2.2.1 Structural formula

A representative structure for CT-2103 is shown in Figure 1. CT-2103 is a random condensation product of acid and paclitaxel.

The structure shown is illustrative of a fragment of the molecule, but specific conjugation sites are not implied. On average, there are approximately 10.4 non-conjugated monomer (m) glutamic acid units per paclitaxel conjugate glutamic acid units (n).
