- Synthetic endogenous cannabinoids analogues and uses thereof
-
The present invention relates to a compound of the general formula (I) which is a non-hydrolysable analogue of endogenous cannabinoids, which are found to be more potent therapeutic agents as they are more stable, for example, to hydrolytic cleavage in the gastrointestinal tract. The cannabinoid analogues of the invention have a therapeutic value. Therefore, pharmaceutical compositions comprising as active ingredient a therapeutically effective amount of at least one compound of the invention may be prepared. Such compositions may be used as anti-inflammatory, anti-asthmatic, analgetic, hypotensive, antiemetic or anti-spasmodic compositions, and as compositions for treating and/or preventing glaucoma or migraine, or as compositions for relieving symptoms of multiple sclerosis and mood stimulating compositions.

- Synthesis and biological activities of 2- arachidonoylglycerol, an endogenous cannabinoid receptor ligand, and its metabolically stable ether-linked analogues
-
We synthesized 2-arachidonoylglycerol (1), an endogenous cannabinoid receptor ligand, and its metabolically stable ether- linked analogues. Compound 1 was synthesized from 1,3- benzylideneglycerol (6) and arachidonic acid in the presence of N,N'-dicyclohexylcarbodiimide and 4-dimethylaminopyridine followed by treatment with boric acid and trimethyl borate. An ether-linked analogue of 2-arachidonoylglycerol (2) was synthesized from 6 and 5,8,11,14-eicosatetraenyl iodide (9). The ether-linked analogues of 2-palmitoylglycerol (4) and 2- oleoyglycerol (5) were synthesized from 6 and hexadecyl iodide (12) and 9-octadecenyl iodide (14), respectively. We confirmed that 1 stimulates NG108-15 cells to induce rapid transient elevation of the intracellular free Ca2+ concentrations through a CB1 receptor-dependent mechanism. Noticeably, 2 exhibited appreciable agonistic activity, although its activity was significantly lower than that of 1. Compound 2 would be a useful tool in exploring the physiological significance of 1, because this compound is resistant to hydrolyzing enzymes in contrast to 1. On the other hand, the ether-linked analogues of either 4 or 5 failed to act as a CB1 receptor agonist. Compounds 4 and 5 would also be valuable as control molecules in experiments where 2 is employed.
