Background

2-fluoropalmitic acid inhibits sphingosine biosynthesis and long-chain acyl-CoA synthetase [1]. The length of the carbon chain of the fatty acid species defines the substrate specificity for the different acyl-CoA synthetases (ACS).

Mammalian long-chain acyl-CoA synthetases (ACSL) activate fatty acids with chain lengths of 12 to 20 carbon atoms. The long-chain acyl-CoA synthetase mRNA is expressed virtually in heart, liver, and epididymal adipose tissues and, to a much lesser extent, in brain, small intestine, and lung [2].

Palmitic acid was a selective cytotoxic substance extracted from the marine algal. At concentrations ranging from 12.5 to 50 μg/ml, palmitic acid showed selective cytotoxicity to human leukemic cells, but no cytotoxicity to normal HDF cells. Palmitic acid (50 μg/ml) induced apoptosis in the human leukemic cell line MOLT-4. Palmitic acid also showed in vivo antitumor activity in mice [3]. 2-fluoropalmitic acid showed an inhibitory effect on sphingosine biosynthesis and long-chain acyl-CoA synthetase with an IC50 value of 0.2 mM [1].
