17-Alpha-Alkylated Steroids

Meaning

17-Alpha-Alkylated Steroids are a class of synthetic anabolic-androgenic steroids ($text{AAS}$) characterized by a specific chemical modification at the $text{C}17alpha$ position of the steroid nucleus. This structural change is intentionally introduced to enable oral administration and prevent the compound’s immediate deactivation by the liver. They are pharmacologically designed for increased bioavailability, but this modification carries significant clinical implications.
