  • Megestrol Acetate is a synthetic progesteronal agent with an IC50 of 260 μM for the inhibition of HegG2.Target: Progesterone ReceptorMegestrol acetate, also known as 17α-acetoxy-6-dehydro-6-methylprogesterone, and sometimes abbreviated as MGA or MA, is a steroidal progestin and progesterone derivative (specifically, a 17-hydroxylated progesterone) with predominantly progestational and antigonadotropic effects. Megestrol acetate is a good candidate for muscle wasting treatment and future studies addressed at the interaction between the drug and protein turnover in human skeletal muscle should be performed.
