AS2444697 is effective in both adjuvant induced arthritis (ED50 2.7 mg/kg, twice daily, orally) and collagen induced arthritis (ED50 1.6 mg/kg, twice daily, orally) disease models in rats. Good bioavailability was observed in pharmacokinetic studies of rats (F% 50) and dogs (F% 78) [1].
AS2444697 (0.3-3 mg/kg) significantly increased the levels of IL-1 β, IL-6, TNF - α, MCP-1, and aminotransferase (ALT and AST) in the plasma of LPS/GalN treated mice. A single dose of AS2444697 (0.3-3 mg/kg) dose dependently reduced plasma levels of all these parameters, and these effects were most significant at doses of 1 mg/kg or higher [2].
After oral administration of AS2444697 (3 mg/kg) to 5/6 Nx rats, the concentration of the unchanged drug in plasma and tissues (liver and kidney) reached its peak at 1 hour and gradually decreased, with a terminal half-life of 2.7-2.9 hours [2].
