Synthesis and structure elucidation of potential 6-oxygenated metabolites of (22R)-6α, 9α-difluoro-11β, 21-dihydroxy-16α, 17α-propylmethylenedioxypregn-4-ene-3, …
(22R)-6α, 9α-Difluoro-11β, 21-dihydroxy-16α, 17α-propylmethylenedioxypregn-4-ene-3, 20- dione (rofleponide) is a synthetic glucocorticosteroid with high affinity for the rat thymus glucocorticoid receptor and a very high biotransformation rate demonstrated through incubation with a human liver S9 subcellular fraction. Because oxidation in the 6-position is an important metabolic pathway of glucocorticosteroids, the potential 6β-hydroxy and 6- ...
