LC3B recruiter 2 (34R) is an LC3B recruiter and a component of the autophagy-lysosome pathway degradation system ( ATTEC, Autophagy-Tethering Compounds), which directly binds to LC3B. LC3B recruiter 2 binds to CDK9 inhibitor SNS-032 through a linker, forming an ATTEC that targets the degradation of the CDK9 and Cyclin T1 complex (with inhibitory effects on both). Therefore, LC3B recruiter 2 exerts activity through the LC3B-dependent autophagy-lysosome pathway, interfering with the cell cycle of cancer cells, thus exhibiting antitumor activity [1].
