Skepinone-L
Cat No.
CEI-1528
Description
Skepinone-L is a selective inhibitor of p38 mitogen-activated protein kinase (MAPK) and TNF-α with IC50 values of 5 nM and 40 nM, respectively.
Product Overview
Skepinone-L is a selective inhibitor of p38 mitogen-activated protein kinase (MAPK) with IC50 value of 5 nM. P38 MAPKs are a class of MAPK which are responsive for stress stimuli, such as heat shock and osmotic shock. They are involved in cell differentiation and apoptosis. Skepinone-L is a ATP-competitive inhibitor of p38 MAPK. For in vitro test, the phosphory¬lation of heat shock protein 27 (HSP27) of the p38 MAPK pathway can be used as a marker to assess the activity of p38 MAPK. When HeLa cells were treated with anisomycin, skepinone-L showed dose-dependent inhibition of HSP27 phosphorylation with a cellular IC50-25 nM, which confirmed the inhibition of p38 MAPK. Additionally, in peripheral blood mononuclear cells (hPBMCs), treatment of skepinone-L resulted in the reduction of p38 MAPK downstream effectors including TNF-α, IL-1β and IL-10.In mouse model, oral administration of skepinone-L resulted in very high level of skepinone-L which was 240 nM and higher than the human whole-blood IC50 value of skepinone. Therefore, it resulted in the inhibition of TNF-α by 77% via the inhibition of upstream p38 MAPK. Thus, it demonstrated the pre¬eminent pharmacodynamic properties of skepinone-L.
