Anagestone

Anagestone (INN), also known as 17α-hydroxy-6α-methylpregn-4-en-20-one, is a steroidal progestin that was never marketed.

An acylated derivative, anagestone acetate, was formerly used clinically as a pharmaceutical drug.

While anagestone is sometimes used as a synonym for anagestone acetate, what is almost always being referred to is actually anagestone acetate and not anagestone.
