The hydrolysis of anandamide has been studied in mouse splenocytes using tritiated anandamide analogs labeled in the acyl- or ethanolamide parts of the molecule. [3H]Anandamide undergoes rapid (t(1/2) = 2.5 min) uptake and hydrolysis, yielding ethanolamine and arachidonic acid. The anandamide hydrolysis in splenocytes is sensitive to inhibition by phenylmethylsulfonyl fluoride, and it is assumed that the observed activity is due to fatty acid amide hydrolase, which inactivates anandamide in central and peripheral tissues. Eicosapentaenoic acid ethanolamide and the 15-hydroxy-derivative of anandamide are shown to be amidohydrolase substrates as well. The fatty acids derived from hydrolytic cleavage of acylethanolamines undergo rapid oxidation by splenocyte lipoxygenase, yielding the corresponding 12-hydroxy-derivatives. Oxygenated ethanolamide derivatives were not found. The data suggest that polyenoic fatty acid ethanolamides are metabolic precursors of eicosanoids in splenocytes and that amide bond hydrolysis is the key point in switching of biological activity spectra between endocannabinoids and oxylipins.
