Biological Activity

Description MKC8866 (IRE1-IN-8866), a salicylaldehyde analog, is a specific IRE1α RNase inhibitor with IC50 of 0.29 μM for human IRE1α in vitro.
Targets
hIRE1α [1]
(Cell-free assay)
0.29 μM
In vitro

MKC8866 is optimized and refined from a family of IRE1α-specific endoribonuclease inhibitors obtained from a chemical library screen. MKC8866 effectively represses IRE1α-mediated XBP1 splicing in PCa cells and has favorable pharmacokinetic and pharmacodynamic properties.[1]
In vivo

MKC8866 is an IRE1α RNase-specific inhibitor molecule that displays significant therapeutic activity in various preclinical models of PCa in vivo. MKC8866 synergizes with clinical PCa drugs in vivo.[1]
