Alisol B 23-acetate (23-Acetylalismol B), a natural triterpenoid, produces protective effects against EE-induced cholestasis, due to FXR-mediated gene regulation. IC50 Value: Target: Anti-hepatotoxic natural product. In vitro: Alisol-B 23-acetate has an effect on FXR activation in a dose-dependent manner using luciferase reporter assay in HepG2 cells [3]. In vivo: In alisol B 23-acetate-treated mice, the changes in transporters and enzymes, as well as ameliorative liver histology were abrogated by FXR antagonist guggulsterone [1]. Alisol B 23-acetate treatment in a dose-dependent manner resulted in protection against hepatotoxicity induced by CCl4via FXR activation. Through FXR activation, alisol B 23-acetate promoted hepatocyte proliferation via an induction in hepatic levels of FoxM1b, Cyclin D1 and Cyclin B1. Alisol B 23-acetate also reduced hepatic bile acids through a decrease in hepatic uptake transporter Ntcp, bile acid synthetic enzymes Cyp7a1, Cyp8b1, and an increase in efflux transporter Bsep, Mrp2 expression. In addition, alisol B 23-acetate induced the expression of STAT3 phosphorylation, and STAT3 target genes Bcl-xl and SOCS3, resulting in decreased hepatocyte apoptosis [2].
