Peficitinib hydrobromide Chemical Properties,Usage,Production

Uses

Peficitinib (ASP015K) hydrobromide 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[1].

Mechanism of action

Peficitinib hydrobromide potently inhibits the JAK-STAT pathway and blocks the signaling of pro-inflammatory cytokines such as IL-6 and IFN-γ. It has the strongest inhibitory activity against JAK3 (IC₅₀ = 0.7 nM), while also taking into account other subtypes (JAK1/2/Tyk2 IC₅₀ 3.9–5.0 nM).

Synthesis

Synthesis of Peficitinib hydrobromide

in vivo

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^[1].

Animal Model:	Seven-weeks-old female Lewis rats, adjuvant-induced arthritis (AIA) model^[1]
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.

IC 50

JAK3: 0.7 nM (IC₅₀); JAK1: 3.9 nM (IC₅₀); Tyk2: 4.8 nM (IC₅₀); JAK2: 5 nM (IC₅₀)
