4μ8C is a selective inhibitor of IRE1α ribonuclease (RNase) activity (IC50 = 60 nM). Blocks substrate access to the active site of IRE1α. Inactivates IRE1α-mediated mRNA degradation. Displays no effect on the IRE1α-related endoribonuclease RNase L.
4mu8C is also offered as part of the Tocriscreen 2.0 Max. Find out more about compound libraries available from Tocris.
