AS1940477 - CAS 928344-12-1

AS1940477 is p38 MAPK inhibitor. AS1940477 inhibited the enzymatic activity of recombinant p38α and β isoforms but showed no effect against other 100 protein kinases including p38γ and δ isoforms. In human peripheral blood mononuclear cells, AS1940477 inhibited lipopolysaccharide (LPS) - or phytohemagglutinin A (PHA) -induced production of proinflammatory cytokines, including TNFα, IL-1β, and IL-6 at low concentrations (LPS/TNFα, IC (50) =0.45n M; PHA/TNFα, IC (50) =0.40 nM) . In addition, equivalent concentrations of AS1940477 that inhibited cytokine production also inhibited TNFα- and IL-1 β-induced production of IL-6, PGE (2), and MMP-3 in human synovial stromal cells. AS1940477 was also found to potently inhibit TNF production in whole blood (IC (50) =12 nM) and effectively inhibited TNFα production induced by systemically administered LPS in rats at less than 0.1mg/kg (ED (50) =0.053 mg/kg) with an anti-inflammatory effect lasting for 20h after oral administration.
