ABT-737 is a novel and potent inhibitor of B-cell lymphoma 2 (BCL-2) family proteins, which are critical for cell survival and overexpressed in many tumor cells, with high affinity towards BCL-XL, BCL-2, and BCL-w but no affinity towards less homologous proteins, such as BCL-B, MCL-1, and A1. ABT-737 has shown single-agent activity against lymphoma and small-cell lung cancer as well as substantial antimyeloma activity both in vitro and in vivo. In recent studies, acute myeloid leukemia blast, origenitor, and stem cells are effectively killed by ABT-737 with normal hematopoietic cells intact. The disruption of the BCL-2/BAX complex and BAK-dependent but BIM-independent activation of the intrinsic apoptotic pathway could also be induced by ABT-737.
