Biological Activity

Description Skepinone-L (CBS3830) is a selective p38α-MAPK inhibitor with IC50 of 5 nM.
Targets
p38α [1]
5 nM
In vitro Skepinone-L shows concentration-dependent inhibition of HSP27 (Ser82) phosphorylation through the p38 MAPK pathway with a cellular IC50 of approximately 25 nM, and also reduces concentrations of TNF-α, IL-1β and IL-10, regulated by p38 MAPK, with IC50 ranging from 30 to 50 nM . [1] Skepinone-L (1 μM) abrogates the phosphorylation of platelet p38 MAPK substrate Hsp27 activated by stimulation with CRP, thrombin or thromboxane A2 analogue U-46619, and impairs platelet secretion and aggregation. [2]
In vivo In vivo, skepinone-L inhibits Gal/ LPS-induced TNF-α release by 77%. [1]
