Peficitinib

Research use only, not for human use.

Peficitinib (ASP-015K, JNJ-54781532) is a potent JAK inhibitor with IC50s of 3.9 and 0.7 nM for JAK1 and JAK3 respectively; inhibits IL-2-dependent T cell proliferation in vitro and STAT5 phosphorylation in vitro and ex vivo.

Peficitinib (ASP-015K, JNJ-54781532) is a potent JAK inhibitor with IC50s of 3.9 and 0.7 nM for JAK1 and JAK3 respectively; inhibits IL-2-dependent T cell proliferation in vitro and STAT5 phosphorylation in vitro and ex vivo; dose-dependently suppresses bone destruction and paw swelling in an adjuvant-induced arthritis model in rats; orally bioactive.Rheumatoid Arthritis Phase 3 Clinical.

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. Cell Proliferation Assay Cell Line:Splenocytes from male Lewis rats Concentration:0-100 nM Incubation Time:3 days Result:Inhibited IL-2-induced T cell proliferation in a concentration-dependent manner with an IC50 of 10 nM.

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.
