GSK583 | RIP2 kinase inhibitor

GSK583 (1346547-00-9) 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 RIP3 kinase (IC₅₀ = 5 nM) but is inactive against RIP3 in cellular assays due to a very low K_M,ATP. GSK583 blocks NOD2 signaling by interfering with XIAP-RIP2 binding resulting in decreased cytokine and chemokine production.^1,2
