生物活性:
Peficitinib (ASP015K) is an orally active JAK inhibitor, with IC50s of 3.9, 5.0, 0.7 and 4.8 nM for JAK1, JAK2, JAK3 and Tyk2, respectively.

体内研究:
Peficitinib hydrobromide (1-30 mg/kg; p.o.; once daily for 24 days) shows dose-dependent efficacy both in prophylactic and therapeutic dosing regimens in an adjuvant-induced arthritis rat model.Animal Model:Seven-weeks-old female Lewis rats, adjuvant-induced arthritis (AIA) model
Dosage:1, 3, 10, and 30 mg/kg
Administration:Oral administration, once daily for 24 days
Result:Significantly inhibited the increase in paw volume at doses of 1 mg/kg or greater with an ED50 value of 2.7 mg/kg (95% confidence interval: 1.5–4.2 mg/kg). Significantly reduced the bone destruction score at 10 mg/kg or greater and almost fully ameliorated both paw swelling and bone destruction scores at 30 mg/kg.

体外研究:
Peficitinib hydrobromide (0-100 nM; 3 days) inhibits IL-2-induced T cell proliferation in a concentration-dependent manner.?Peficitinib hydrobromide (10-1000 nM) inhibits IL-2-induced STAT5 phosphorylation in a concentration-dependent manner with a mean IC50 of 124 nM in rat whole blood, and inhibits STAT5 phosphorylation with a mean IC50 of 127 nM in human lymphocytes.
