Uses and applications

What the substance is used for, by industry and function

Pharmacology

Colestolone is an antilipidemic agent based on the carbon skeleton of cholesterol. Colestolone targets sterol regulatory element binding protein (SREBP) which reduces the transcription of the 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR) gene, the rate-limiting enzyme in the sterol pathway. Colestolone is also metabolized by cells into polar sterols, which are known to inhibit HMGCR enzymatic activity.
