Employing a structure-based strategy, we have designed a new class of potent small-molecule inhibitors of the anti-apoptotic proteins Bcl-2 and Bcl-xL. An initial lead compound with a new scaffold was designed based upon the crystal structure of Bcl-xL and FDA-approved drugs and was found to have an affinity of 100 μM to both Bcl-2 and Bcl-xL. Linking this weak lead to another weak-affinity fragment derived from Abbott's ABT-737 led to an improvement of the binding affinity by a factor of >10,000. Further optimization ultimately yielded compounds with subnanomolar binding affinities to both Bcl-2 and Bcl-xL and potent cellular activity. The best compound (21) binds to Bcl-xL and Bcl-2 with Ki < 1 nM, inhibits cell growth in the H146 and H1417 small-cell lung cancer cell lines with IC50 values of 60–90 nM and induces robust cell death in the H146 cancer cell line at 30–100 nM.
