Ki: 6 nM for BCL-2 TR-FRET

A-1331852 is a potent and selective inhibitor of BCL-XL.

Apoptosis is reported to be regulated by a family of closely related proteins exemplified by B cell lymphoma protein 2 (BCL-2), which is the first discovered family member. BCL-2 family proteins are divided by one to four BCL-2 homology motifs and can be further subdivided into pro- and antiapoptotic subsets.

In vitro: A-1331852 was identified as a potent BCL-XL inhibitor demonstrating cellular activity 10- to 50-fold more potent than its analog A-1155463 and the previouly reported BCL-XL inhibitor, navitoclax, respectively. Moreover, A-1331852 could selectively disrupt BCL-XL–BIM complexes and induce the apoptosis hallmarks in BCL-XL–dependent Molt-4 cells with median IC50 values in the low nanomolar range but did not affect MEF cells without BAK or BAX [1].

In vivo: Previous animal study found that A-1331852 could demonstrate antitumor efficacy in the Molt-4 xenograft model, such as tumor regressions as a single agent. In addition, in the NCI-H1963.FP5 xenograft model of SCLC, it was found that A-1331852 combined with venetoclax was able to recapitulate the efficacy of navitoclax [1].

Clinical trial: Up to now, A-1331852 is still in the preclinical development stage.
