DETAILS

Selleck Chemicals - S1304

Research Area: Cancer
Biological Activity:
Megestrol Acetate is a synthetic progesteronal agent with an IC50 of 260 μM for the inhibition of HegG2. It inhibits the growth of HepG2 cells in vitro in dose- and time-dependent manners. Megestrol is a progesterone derivative with antineoplastic properties used in the treatment of advanced carcinoma of the breast and endometrium. When given in relatively high doses, Megestrol can substantially increase appetite in most individuals, even those with advanced cancer. It is also used to boost appetite in individuals with other cancers or HIV/AIDS. [1][2][3]References on Megestrol Acetate[] Clin Cancer Res, 2004, 10:5226-5232
