COA Handling Instructions

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

Description

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

In Vitro

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

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
