Etomoxir
Description
Etomoxir (Eto; 2[6(4-chlorophenoxy)hexyl]oxirane-2-carboxylate) is an irreversible inhibitor of carnitine palmitoyltransferase-1 (CPT-1) on the outer face of the inner mitochondrial membrane. Eto inhibits the transport of the long-chain fatty acids from the cytosol into the mitochondrial matrix, thereby blocking the formation of acyl carnitines in the cytosol, leading finally to inhibition of the fatty acid oxidation. Of note, in contrast to long-chain fatty acids, the transport of short- and medium chain fatty acids is carnitine-independent. The commercially available white compound is soluble in water.
