Acyl-CoA synthetase inhibitor. Analog of polyunsaturated fatty acid. Potent inhibitor of long-chain fatty acyl CoA synthetase. Selectively inhibits arachidonoyl-CoA synthetase in intact cells and the nonspecific acyl-CoA synthetase in cell sonicates IC50=3.6-8.7µM. Inhibits neutrophil functions. Blocks β-cell apoptosis induced by fatty acids (lipoapoptosis) and synthesis of triglycerides, diglycerides and cholesterol esters. Potent vasodilator.
