SNIPER(BRD)-1 is a chemical compound composed of a derivative of the IAP antagonist LCL-161 and the BET inhibitor (+)-JQ-1, linked together. It promotes the degradation of BRD4 through the ubiquitin-proteasome pathway and effectively degrades cIAP1, cIAP2, and XIAP with IC50 values of 6.8 nM, 17 nM, and 49nM, respectively[1].
XIAP BIR2/BIR2-3 Inhibitor-3 functions as a dual inhibitor targeting both BIR2 and BIR2-3 domains, exhibiting potent activity with IC50 values below 1 nM. This compound is utilized in cancer research [1].
