• 产品描述： SB-242235 is a potent and selective p38 MAP kinase inhibitor, with an IC50 of 1.0　μM in primary human chondrocytes

• 靶点： IC50: 1.0　μM (p38 MAPK, primary human chondrocytes);p38MAPK; Autophagy

• 体外研究：
  SB 242235 (0-10　μM) dose-dependently inhibits the activation of MAPKAP K2 with an IC50 of 1.0 μM in human chondrocytes stimulated with IL-1β. SB 242235 inhibits intracellular p38 activity, MAPKAP K2 was then isolated from these cells and assayed using HSP27 as a substrate. Western Blot Analysis Cell Line: Human chondrocytes Concentration: 0 μM,0.01 μM,0.1 μM,1 μM,10　μM Incubation Time: 15 minutes Result: Dose-dependently inhibited the activation of MAPKAP K2 with an IC50 of 1.0 μM.

• 体内研究：
  SB242235 (100 mg/kg; p.o.) abolishes MAP-KAPK-2 activity and HSP27 phosphorylation. SB242235 inhibits expression of the pro-inflammatory cytokines interleukin (IL)-6 and KC (murine IL-8) and COX-2. SB-242235 is demonstrated non-linear elimination kinetics that manifested as a decrease in clearance with increasing dose and apparent oral bioavailability > 100% at high oral doses in rat and monkey. Animal Model: Female SKH-1 hairless mice (4–6 weeks) Dosage: 100 mg/kg Administration: Oral administered, 30 minutes prior to ultraviolet B (UVB) irradiation Result: Abolished MAP-KAPK-2 activity and heat shock protein 27 (HSP27) phosphorylation.
