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].
SM-164 Hydrochloride is a cell-permeable Smac mimetic compound. SM-164 binds to XIAP protein containing both the BIR2 and BIR3 domains(IC50 value of 1.39 nM) and functions as an extremely potent antagonist of XIAP.
SNIPER(ABL)-039, conjugating Dasatinib (ABL inhibitor) to LCL161 derivative (IAP ligand) with a linker, induces the reduction of BCR-ABL protein with a DC50 of 10 nM. IC50s are 0.54 nM, 10 nM, 12 nM, and 50 nM for ABL, cIAP1, cIAP2, XIAP, respectively[1].
