生物活性

製品説明 Ritlecitinib (PF-06651600) is a potent and irreversible JAK3-selective inhibitor with an IC50 of 33.1 nM but without activity (IC50 > 10 000 nM) against JAK1, JAK2, and TYK2.
in vitro Ritlecitinib (PF-06651600), a newly discovered potent JAK3-selective inhibitor, is highly efficacious at inhibiting γc cytokine signaling, which is dependent on both JAK1 and JAK3. In vitro, it inhibits Th1 and Th17 cell differentiation and function. In total lymphocytes in human whole blood, this compound inhibits the phosphorylation of STAT5 elicited by IL-2, IL-4, IL-7, and IL-15 with IC50 values of 244, 340, 407, and 266 nM, respectively, and it inhibits the phosphorylation of STAT3 elicited by IL-21 with an IC50 of 355 nM[1].
in vivo In vivo, Ritlecitinib (PF-06651600) reduces disease pathology in rat adjuvant-induced arthritis as well as in mouse experimental autoimmune encephalomyelitis models. It has suitable pharmacokinetics and pharmacodynamics properties for preclinical and clinical evaluations. Human pharmacokinetics of this compound are predicted to show approximate values of blood clearance of 5.6 mL/min/kg, a steady state volume of distribution of 1.3 L/kg, oral bioavailability of 90%, and a systemic half-life of 2 h[1].
