ABT-737

The family of Bcl-2 proteins plays pivotal roles in either promoting or preventing apoptosis. Bcl-2 family members contain one or more of four characteristic Bcl-2 homology (BH) domains, which are crucial for function. For example, anti-apoptotic Bcl-2 family proteins prevent death signaling by heterodimerizing with pro-death proteins at their BH3 domains. ABT-737 is a potent, cell-permeable mimetic of BH3 domains that avidly binds Bcl-2, Bcl-xL, and Bcl-W (Ki death proteins, leading to apoptosis. ABT-737, alone, can induce regression of some tumors in some xenograft mouse models of cancer. It shows synergy with diverse therapeutics and radiation to trigger apoptosis in cancer cells and xenografts.Formal Name: 4-[4-[(4'-chloro[1,1'-biphenyl]-2-yl)methyl]-1-piperazinyl]-N-[[4-[[(1R)-3-(dimethylamino)-1-[(phenylthio)methyl]propyl]amino]-3-nitrophenyl]sulfonyl]-benzamide.
