Endocannabinoids are endogenous polyunsaturated fatty acids involved in a multitude of health and disease processes. Recently, several lines of evidence suggest the presence of a novel non-CB1/CB2 anandamide receptor in endothelial cells. Thus, we synthesized two types of photoaffinity probes that contain either an arylazide group or a diazirin moiety, together with a fluorescent analogue. The key steps rely on selective hydrogenation of skipped tetrayne backbones and on copper-mediated cross-coupling reactions between diynic precursors. Three synthetic routes were investigated. In biological functional assays, we found that both the arylazide and the fluorescent probes induced robust increases in matrix metalloprotease activity and produced positive angiogenic responses in in vitro endothelial cell tube formation assays. Irradiation of the arylazide probe nicely enhanced this effect in both HUVEC and CBI-KO HUVEC. These results suggest that the arylazide and the fluorescent probes can be used to identify "non-C131/CB2 anandamide receptor" from endothelial cells.

One aspect of this disclosure relates generally to lipid compounds that exert diverse effects in the endocannabinoid system, such as regulating CB1 and CB2 receptor or moderating other bio-macromolecules within the endocannabinoid system. Some of the compounds showed improved receptor binding affinity, and/or improved receptor subtype selectivity, and improved bio-stability. Some of the compounds exhibit activities to regulate the enzymes that moderate the bio-disposal of endogenous cannabinoids, such as the fatty acid amide hydrolase (FAAH). Some of the compounds exhibit activities to inhibit the anandamide transporter. Other aspects of the invention are pharmaceutical preparations employing these ligands and methods of administering therapeutically effective amounts of the preparations to provide a physiological effect.

A potential photoreactive analog of anandamide was synthesized via selective hydrogenation of a skipped tetrayne intermediate. This compound might be a useful tool to search for new cannabinoid receptors.
