Bioactivity Comments
PF-06650833 inhibits TLR7/8 agonist R848-induced TNFα production in human peripheral blood mononuclear cells with an IC50 of 2nM [1]. Further preclinical results detailing the pharmacokinetic and ADME profiles of PF-06650833 are reported in [1]. In a kinome selectivity profile 200nM PF-06650833 completely inhibited IRAK4 activity, and inhibited the additional kinases IRAK1, MNK2, LRRK2, CLK4, and CK1γ1 by > 70%. In a more physiologically relevant screen, other than IRAK4, 200nM PF-06650833 inhibited only CK1γ2, IRAK3/M, PIPK2C, and CK1δ/ε by > 50%.
