FIGURE 59-4 Structure and nomenclature of corticosteroid products and selected synthetic derivatives. The structure of hydrocortisone is represented in two dimensions. The steroid ring system is not completely planar and the orientation of the groups attached to the steroid rings is an important determinant of the biological activity. The methyl groups at C18 and C19 and the hydroxyl group at C11 project upward (forward in the two-dimensional representation and shown by a solid line connecting the atoms) and are designated fi. The hydroxyl at C17 projects below the plane (behind in the two-dimensional representation, and represented by the dashed line connecting the atoms) and is designated a.
