Gene Information

human ... DHCR24(1718) , EBP(10682)

Application

Triparanol has been used to inhibit cholesterol biosynthesis in lipid rafts1. Triparanol has also been used as a 3β-hydroxysterol-Δ24-reductase inhibitor to study its effect on delayed-rectifier potassium current (Iks) channels2.

Biochem/physiol Actions

Triparanol is known to repress Hedgehog signaling in cancer cells and can also inhibit tumor growth3.
Desmosterol Delta24 (D24) reductase inhibitor.

Preparation Note

Triparanol is soluble in DMSO at 20 mg/ml and is also soluble in alcohol. It is slightly soluble in olive oil and is insoluble in water.

The tetracyclic sterol precursors, cyclolaudenol, cycloartenol and lanosterol, inhibit efficiently the tetrahymanol biosynthesis in the ciliate Tetrahymena pyriformis, as reported earlier for cholesterol and other sterols. The prokaryotic bacteriohopanetetrols have little effect, and diplopterol, another hopanoid, as well as the

The relationships between the cholesterol content of the diet, plasma cholesterol concentration, cholesterol absorption, and cholesterol synthesis (measured indirectly by desmosterol suppression technique) are explored in groups of high- and low-responding rhesus monkeys fed diets containing 0.02, 0.15 and 0.75

Paramecium requires oleic acid for growth and can grow in media containing no other fatty acids. In the present study, we have shown that this ciliate utilized oleate mainly as a carbon and energy source, even though this fatty acid

We showed previously that 3 distal inhibitors of cholesterol synthesis are highly teratogenic in rats. AY 9944 and BM 15766 inhibit 7-dehydrocholesterol reductase, which catalyzes the last step of cholesterol synthesis, and triparanol inhibits Delta(24)-dehydrocholesterol reductase, which catalyzes the last
