GSK583

GSK583 is a highly selective and potent inhibitor of RIP2 kinase, IC50 = 5 nM human and IC50 = 2 nM rat.1 It also potently Inhibits isolated RPI3 kinase (IC50 = 5 nM) but is inactive against RIP3 in cellular assays due to a very low KM, ATP. GSK583 blocks NOD2 signaling by interfering with XIAP-RIP2 binding resulting in decreased cytokine and chemokine production.1,2
