This is a list of corticosteroids (glucocorticoids and mineralocorticoids) or derivatives of cortisol (hydrocortisone). Most esters of these corticosteroids are not included in this list; for esters, see here instead. The most common structural modifications in synthetic corticosteroids include 1(2)-dehydrogenation, 6α-, 9α-, 16α-, and 16β-substitution (with a halogen or methyl group), 16α,17α-acetonidation, and 17α- and 21-esterification.
