3INQ, 3IO8, 3IO9 - PubMed Abstract: 
Antagonists of anti-apoptotic Bcl-2 family members hold promise as cancer therapeutics. Apoptosis is triggered when a peptide containing a BH3 motif or a small molecule BH3 peptidomimetic, such as ABT 737, binds to the relevant Bcl-2 family members. ABT-737 is an antagonist of Bcl-2, Bcl-x(L), and Bcl-w but not of Mcl-1 ...
