Avasimibe (CI 1011) is a potent ACAT (Acyl-CoA:cholesterol acyltransferase) inhibitor. Avasimibe inhibits both ACAT1 and ACAT2 isoforms. Avasimibe was in development by Parke-Davis (now Pfizer) in the US for the treatment of atherosclerosis and hyperlipidaemia. Avasimibe was in phase III studies and more than 1300 patients had been treated for up to one year, however, in October 2003, Pfizer announced that development had been discontinued.

Eflucimibe is a new and potent Acyl coenzyme A:cholesterol acyltransferases inhibitor. Eflucimibe effectively decreased plasma cholesterol in cholesterol-fed animals. In animal models, drug restores normolipodemia in endogenous hypercholesterolemic rabbits and prevents the progression of atherosclerosis by decreasing the number of macrophages in the foam cells. Eflucimibe has been in phase II clinical trials for the treatment of atherosclerosis and hyperlipidemia. However, this research has been discontinued.

Folipastatin is a depsone metabolite first isolated from Aspergillus unguis by researchers at Sankyo, Japan in 1992 as an inhibitor of phospholipase A2. Folipastatin also possesses moderate antibiotic activity as against Gram positive bacteria. It is a component of a mixture of unguinol-related metabolites produced by A. unguis and A. nidulins patented as growth promotants in livestock. More recently, folipastatin was reported as an inhibitor of sterol O-acyltransferase (SOAT) 1 and 2 iso-enzymes in cell-based and enzyme assays.
