产品介绍

产品描述

25S-Inokosterone and 25R-inokosterone exhibit potent inhibition (80-95% at ) against TNF-expression levels in A23187 plus phorbol-myrisrate acetate-induced RBL-2H3 cells, they have excellent anti-atopy activity, thus they could be used to a large range of functional anti-atopy cosmetics.

体外活性

Three compounds were isolated from the subfraction 5 through the repeated prep- high performance liquid chromatography column chromatography. According to the results of physico-chemical and spectroscopic data including NMR and MS, the chemical structures of the compounds were determined as ecdysterone (1), 25S-inokosterone (2), and 25R-Inokosterone (3). Three phytoecdysones were showed weak inhibitory activity for thymus and activation-regulated chemokine expression levels in tumor necrosis factor (TNF)-α± plus IFN-γ induced HaCaT cells, respectively. However, those compounds 1-3 were exhibited the most potent inhibition (80??95% at 200 μg/mL) against TNF-α± expression levels in A23187 plus phorbol-myrisrate acetate-induced RBL-2H3 cells.
