MedChemExpress - Model Larsucosterol sodium - 1174047-40-5

Larsucosterol (DUR-928) sodium, a cholesterol metabolite, is a potent liver X receptor (LXR) antagonist. Larsucosterol sodium as a potent endogenous regulator decreases lipogenesis. Larsucosterol sodium inhibits the cholesterol biosynthesis via decreasing mRNA levels and inhibiting the activation of SREBP-1[1][2][3].

Description：Larsucosterol (DUR-928) sodium, a cholesterol metabolite, is a potent liver X receptor (LXR) antagonist. Larsucosterol sodium as a potent endogenous regulator decreases lipogenesis. Larsucosterol sodium inhibits the cholesterol biosynthesis via decreasing mRNA levels and inhibiting the activation of SREBP-1.

In Vitro：Larsucosterol (DUR-928; 0-25 μM; 8 h; HepG2 cells) sodium inhibits cholesterol biosynthesis by decreasing HMG-CoA reductase mRNA levels and decreases free [14C] cholesterol in a dose-dependent manner[1]. Larsucosterol (0-25 μM; 6 h; HepG2 cells) sodium inhibits HMG-CoA reductase expression by inhibition of both SREBP1 activation and expression in hepatocytes[1]. Larsucosterol (0-50 μM; 48 h) sodium increases cell proliferation and decreases apoptosis in macrophages[2]. Larsucosterol (0-25 μM; 48 h; macrophages) sodium inhibits activation of liver oxysterol receptor LXRα[2].

In Vivo：Larsucosterol (DUR-928; 25 mg/kg; i.p.; twice in 14 hours; C57BL/6J mice with nonalcoholic fatty liver diseases (NAFLD) model) sodium reduces serum lipid levels in mice fed a high-fat diet[3]. Larsucosterol (25 mg/kg; i.p.; twice in 14 hours; C57BL/6J mice with nonalcoholic fatty liver diseases (NAFLD) model) sodium suppressed the expression of the genes and inhibits ABCA1 expressionde. Larsucosterolcreases nuclear SREBP-1 Protein levels and cytoplasmic FAS and ACC1 protein levels in liver tissue[3]. Larsucosterol (25 mg/kg; i.p.; once every 3 days for 6 weeks; C57BL/6J mice with nonalcoholic fatty liver diseases (NAFLD) model) sodium protects the liver from injury by suppressing hepatic inflammation[3].
