Biological Activity for AT 101

AT 101 is a R-(-)-enantiomer of gossypol (Cat. No. 1964). Mimics the BH3 domains of Bcl-2, Bcl-XL and Mcl-1. Disrupts heterodimerization of Bcl-2 with proapoptotic family members. Induces apoptosis in vitro through activation of caspase-9; cytotoxic to multiple myeloma and drug-resistant cell lines. Delays onset of androgen-independent growth of VCaP prostate cancer xenografts in vivo.
