S55746（Cat No.:I019789）, also known as S 055746 or BCL201 is a novel BCL-2-specific inhibitor that is taken orally and demonstrates high activity. It has a Ki (inhibition constant) of 1.3 nM, indicating strong binding affinity. While it exhibits weak affinity for Bcl-XL and no significant binding for MCL-1 and BFL-1 (BCL2A1/A1), S55746 is highly selective for BCL-2, with a selectivity range of 70-400 times greater compared to BCL-XL.
