Description
Tamatinib, also known as R-406, is a potent inhibitor of Syk with IC50 of 41 nM. R406 impairs platelet activation and monocyte tissue factor expression triggered by heparin-PF4 complex directed antibodies. R406 blocks fc receptor signaling and reduces immune complex-mediated inflammation. R406 inhibited phosphorylation of Syk substrate linker for activation of T cells in mast cells and B-cell linker protein/SLP65 in B cells. R406 bound to the ATP binding pocket of Syk and inhibited its kinase activity as an ATP-competitive inhibitor (K(i) = 30 nM). R406 blocked Syk-dependent FcR-mediated activation of monocytes/macrophages and neutrophils and BCR-mediated activation of B lymphocytes. (last updated: 6/29/2016)
