IC50: 1.0 μM (p38 MAPK, primary human chondrocytes)
SB 242235 (0-10 μM) dose-dependently inhibits the activation of MAPKAP K2 with an IC
50
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.

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. |
