<unk> , also known as megestrol 3β,17α-diacetate, as well as 3β-dihydro-6-dehydro-6-methyl-17α-hydroxyprogesterone diacetate or as 3β,17α-diacetoxy-6-methylpregna-4,6-dien-20-one, is a synthetic pregnane steroid and a derivative of progesterone and 17α-hydroxyprogesterone. It is very close to megestrol acetate (6-dehydro-6-methyl-17α-acetoxyprogesterone) in structure, except that there is a hydroxyl group with an acetate ester attached at the C3 position instead of a ketone. A closely related medication is cymegesolate (also known as megestrol 3β-cypionate 17α-acetate), which, in contrast, has not been marketed.
