PRT062607 (P505-15) acetate is an orally available Syk inhibitor (IC50: 1 nM) that inhibits inflammation and induction Apoptosis.[1][2].
PRT062607 acetate also has significant activity against multiple kinases, with IC50s of 81 nM (Fgr), 88 nM (MLK1), 123 nM (Yes), 139 nM (Flt3), 166 nM (PAK5), 192 nM (Lyn), 244 nM (cSRC), 249 nM (Lck), 108 nM (Pyk), 415 nM (FAK), 1.05 nM (ZAP-70)[1].PRT062607 acetate (0.01-2 μM; 3 d) inhibits Phosphorylation of ERK(Y204), AKT(S473) and SYK(Y352) in Ramos cells, and inhibition of BLNK Tyr84 phosphorylation[1][2].PRT062607 acetate (2 μM; 24 h) in SU-DHL6 cells Induces apoptosis in human whole blood[1].In human whole blood, P505-15 can effectively inhibit B cell antigen receptor-mediated B cell signaling and activation (IC50: 0.27 and 0.28 μM) and Fc receptor 1-mediated induced basophil degranulation (IC50: 0.15 μM)[2].
PRT062607 acetate produced dose-dependent anti-inflammatory activity in two rodent models of rheumatoid arthritis.
