MedKoo CAT#: 406841

CAS#: 1430844-80-6

Description: A-1331852 is a potent and BCL-XL-selective inhibitor. BCL-XL is the major antiapoptotic survival protein and may be a novel therapeutic target in CML. BCL-XL-selective inhibitors have the potential to enhance the efficacy of docetaxel in solid tumors and avoid the exacerbation of neutropenia observed with navitoclax. A-1331852 may have potential as improved cancer therapeutics.
