Abstract
Anandamide (Figure 1a) (arachidonyl ethanolamide, AEA), (5Z,8Z,11Z,14Z)โNโ(2โhydroxyethyl)โ5,8,11,14โEicosatetraenamide, is an endogenous cannabinoid ligand possessing important biological activity. The conformation of AEA in its native receptor binding environment is particularly of interest for pharmaceutical research and biochemistry in general. Here we report a novel synthetic pathway, which selectively introduces ^15^N and ^13^C isotopes into the anandamide molecule. This isotopically labeled AEA can be studied conformationally in its native binding condition via solid state NMR. These synthetic procedures can also be adapted to produce radioactive ligands for receptor binding assays and other structural studies. Copyright ยฉ 2002 John Wiley & Sons, Ltd.
