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].
BRD PHOTAC-I-3 is a photoswitchable BET bromodomain degrader (PHOTAC, PHOtochemically TArgeting Chimera). BRD PHOTAC-I-3 comprises a ligand for an E3 ligase, a photoswitch, and the BET bromodomain targeting ligand (+)-JQ1. Exhibits cytotoxicity and degrades BRD4, BRD3 and to a lesser extent BRD2 in lymphoblast cells upon irradiation with 390 nm light, but not in the dark.
