Description

Biochem/physiol Actions

BIR domain-targeting degrader of inhibitor of apoptosis proteins (IAPs) cIAP1/2 and XIAP.



CST626 is a degrader of cellular inhibitor of apoptosis (IAP) proteins (cIAP1/cIAP2/XIAP DC50 post 16h = 2.4/6.2/0.7 nM with >99% degradation observed post 3h treatment at 100 nM; MM1S cells) that effectively reduces the viability of hematological cancer cultures, including MM (IC50 post 96h = 8.5 nM/NCI-H929, 1.14µM/JJN3, 2.54 µM/RPMI-8826), AML (IC50 post 96h = 2.1 nM/MOLM13, 420 nM/K562, 1.17 µM/HEL) and DLBCL (IC50 post 96h = 1.6 nM/SUDHL6, 460 nM/DB, 1.69 µM/SUDHL4). CST626 is composed of a von Hippel-Lindau (VHL) ligand VH032 derivative linked to a monovalent Smac (DIABLO) AVPI motif-based IAP BIR domain-targeting ligand.
