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

Biologische Aktivität
Larsucosterol (DUR-928; 0-25 μM; 8 h; HepG2 cells) 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) inhibits HMG-CoA reductase expression by inhibition of both SREBP1 activation and expression in hepatocytes[1].
Larsucosterol (0-50 μM; 48 h) increases cell proliferation and decreases apoptosis in macrophages[2].
Larsucosterol (0-25 μM; 48 h; macrophages) inhibits activation of liver oxysterol receptor LXRα[2].

Larsucosterol (25 mg/kg; i.p.; twice in 14 hours; C57BL/6J mice with nonalcoholic fatty liver diseases (NAFLD) model) 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) protects the liver from injury by suppressing hepatic inflammation[3].
