体外研究 (In Vitro) | Peficitinib hydrobromide (0-100 nM; 3 days) inhibits IL-2-induced T cell proliferation in a concentration-dependent manner[1]. Peficitinib hydrobromide (10-1000 nM) inhibits IL-2-induced STAT5 phosphorylation in a concentration-dependent manner with a mean IC50of 124 nM in rat whole blood, and inhibits STAT5 phosphorylation with a mean IC50of 127 nM in human lymphocytes[1].
Cell Proliferation Assay[1] 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 IC50of 10 nM. |

体内研究 (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 ED50value 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. |
