    Abstract:
    Anandamide (AEA) presents the four double bonds in the cis configuration, deriving from the arachidonic acid moiety. In the context of an antisense strategy based on the double bond configuration, all-trans AEA (t-AEA) was synthesized in high yield starting from all-trans methyl arachidonate and ethanolamine in the presence of KCN. t-AEA was assayed on rabbit platelet aggregation, obtaining effect only at high concentrations (>10(-4) M) after an also concentration-dependent lag phase. At lower concentrations it inhibited PAF-induced rabbit platelet aggregation with an IC(50)=4.6 x 10(-6) M. In contrast to anandamide, the activation of platelets was not due to the conversion of t-AEA to trans arachidonic acid, as ascertained by negative results with FAAH inhibitors. However, t-AEA was found to be a substrate for fatty acid amide hydrolase (FAAH), the enzyme that cleaves anandamide and regulates in vivo the magnitude and duration of the signaling induced by this lipid messenger.
