A-1155463（Cat No.:I000937） is a potent and selective inhibitor of B-cell lymphoma-extra large (BCL-XL), which plays a key role in regulating apoptosis or programmed cell death. The drug binds to BCL-XL with high affinity at the picomolar level and exhibits more than 1000 times weaker binding affinity to BCL-2, BCL-W (Ki=19nM), and MCL-1 (Ki>440nM). The selective inhibition of BCL-XL by A-1155463 induces apoptosis in cancer cells and has shown promising anti-tumor activity in preclinical studies.
