What is 16-Dehydropregnenolone acetate (979-02-2) used for?

16-Dehydropregnenolone Acetate is used in the preparation of pregnane derivatives and its glycosides as potential anticancer agents. A stereoselective total synthesis of naturally occurring 20-epi cholanic acid derivatives has been realized, starting from readily available 16-dehydropregnenolone acetate. Novel sulphur derivatives have been synthesized for the first time from 16-Dehydropregnenolone acetate (16-DPA) by adopting thia-Michael addition reaction yielding 2-[(3β-acetoxy) pregn–5-ene-20-one −16 –thio] propanoic acid, 2-[(3β-acetoxy) pregn–5-ene-20-one–16–thio] ethanoic acid, 3β-acetoxy 16α-(2-hydroxyethylthio)-pregn-5-ene-20-one and 3β-acetoxy-16β-(2-amino phenylthio)-pregn-5-ene-20-one.
