Abstract
Abstract Ethyl 2{5(4-chlorophenyl)pentyl}oxiran-2-carboxylate (POCA) is a new hypoglycaemic compound. The POCA-CoA ester strongly inhibits β-oxidation at carnitine palmitoyltransferase I. Chronic administration of POCA to rats decreases plasma concentrations of cholesterol and triacylglycerol and increases the number of hepatic peroxisomes similarly to hypolipidaemic drugs related to clofibrate. Peroxisomal fractions from rats fed a diet containing 0.2% of POCA for 4 weeks were prepared on self-generated Percoll gradients. POCA induced a 4-fold increase in catalase activity and peroxisomal β-oxidation, agreeing with the morphological data. The increase in peroxisomal β-oxidation caused by POCA feeding does not prevent accumulation of lipid following the inhibition of mitochondrial β-oxidation.
