Application

Avasimibe has been used as an inhibitor of acyl-coenzyme A: cholesterol acyltransferase (ACAT) in Huh7.5.1 cells for testing its combination with direct-acting antivirals (DAAs) and to test its effect on lipid droplet accumulation in acidosis-adapted cancer cells. It may be used as an inhibitor of ACAT to assess cholesterol esterification in Trypanosoma cruzi.

Biochem/physiol Actions

Avasimibe (CI-1011) is an orally bioavailable Acyl-CoA:Cholesterol O-Acyltransferase (ACAT) inhibitor. It was originally developed as an antilepic drug, and was shown to significantly reduce plasma total triglyceride and VLDL-cholesterol, but later clinical trials were disappointing. ACAT has also been investigated as a potential therapeutic target for Alzheimer′s disease. Recent studies have looked at the effects of avasimibe in reducing amyloid pathology by limiting generation and increasing clearance of diffusible amyloid-beta (Abeta).

It is now recognized that atherosclerosis complications are related to the unstable character of the plaque rather than its volume. Vulnerable plaques often contain a large lipid core, a reduced content of smooth muscle cells, and accumulation of inflammatory cells.

Previously, we have shown, in vivo, that the acyl coenzyme A: cholesterol acyltransferase (ACAT) inhibitor avasimibe decreases hepatic apolipoprotein (apo) B secretion into plasma. To test the hypothesis that avasimibe modulates postprandial triglyceride-rich lipoprotein (TRL) metabolism in vivo, an oral

Avasimibe (also known as CI-1011 or PD-148515) is a selective acyl-coenzyme A:cholesterol O-acyltransferase (ACAT) inhibitory lipid-regulating agent under development by Pfizer (formerly Parke-Davis) for the potential treatment of hyperlipidemia and atherosclerosis. The compound is currently undergoing phase III clinical trials

Inhibition of the acyl coenzyme A:cholesterol acyltransferase (ACAT) enzyme may prevent excess accumulation of cholesteryl esters in macrophages. The ACAT inhibitor avasimibe was shown to reduce experimental atherosclerosis. This study was designed to investigate the effects of avasimibe on human

We assessed vascular changes during atherosclerosis regression. Compensatory enlargement of coronary arteries accommodates plaque burden during atherosclerosis development. Lipid-lowering therapy has altered the natural history of coronary atherosclerosis, but the arterial changes that occur during disease regression need to be
