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

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

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.

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
