Biochem/physiol Actions

16-Dehydropregnenolone acetate (DPA) is synthesized from steroids sapogenin, diosgenin and solasodine. 16-Dehydropregnenolone acetate (DPA) is a crucial intermediate for the synthesis of steroid hormones-based drugs. It is an antagonist for farnesoid X receptor (FXR) and modulates cholesterol metabolism. It is considered as a potential antihyperlipidemic agent. Chemically synthesized steroid derivatives from DPA have cytotoxic features and could serve as potential anticancer agents.
