Biological Activity

Description Skepinone-L (CBS3830) is a selective p38α-MAPK inhibitor with IC50 of 5 nM.
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]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
