PK68 is a potent and selective type II inhibitor of receptor-interacting kinase 1 (RIPK1) with an IC50 of ~90 nM, displays inhibition of RIPK1-dependent necroptosis. PK68 powerfully ameliorates TNF-induced systemic inflammatory response syndrome, and with great potential for use in the treatment of inflammatory disorders and cancer metastasis[1]. IC50: ~ 90 nM (RIPK1)[1]
