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.

Acetates of 3beta-hydroxy-3'-methyl-1'(N)-acylandrost-5-eno[16,17-d]pyrazolines bearing monothiooxamide acyl groups were synthesized during the study of approaches to the synthesis of 3'-methylandrosteno[16,17-d]azoles, promising biologically active analogues of 20-keto pregnenanes, and their properties were investigated. The cyclization of delta16-20-thiooxamidohydrazones to the corresponding heterocycles was
