Description: |
Peficitinib is an oral JAK inhibitor, with IC50s of 3.9, 5.0, 0.7 and 4.8 nM for JAK1, JAK2, JAK3 and Tyk2, respectively. |
In Vivo: |
Peficitinib (20 mg/kg, p.o.) suppresses IL-2-induced STAT5 phosphorylation by 78% in the rat model of adjuvant-induced arthritis (AIA). Peficitinib potently inhibits the increase in paw volume (≥1 mg/kg) with an ED50 of 2.7 mg/kg, significantly reduces the bone destruction score (≥10 mg/kg) and almost fully ameliorates both paw swelling and bone destruction scores (30 mg/kg)[1]. |
In Vitro: |
Peficitinib is an oral JAK inhibitor, with IC50s of 3.9, 5.0, 0.7 and 4.8 nM for JAK1, JAK2, JAK3 and Tyk2, respectively. Peficitinib inhibits IL-2-induced T cell proliferation with an IC50 of 10 nM. Peficitinib also suppresses the IL-2-induced STAT5 phosphorylation in rat and human whole blood, with mean IC50s of 124 nM and 127 nM, respectively[1]. |
