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.
