Hemisynthesis and preliminary evaluation of novel endocannabinoid analogues
摘要:
Three new endocannabinoid analogues in which amide moiety was replaced either by oxomethylene group or ester moiety with simultaneous substitution of both alpha-hydrogens with methyl groups were synthesized and their abilities to interact with CB1-receptor and FAAH were investigated.

Potent inhibitors of fatty acid amide hydrolase (FAAH) are constructed having Ki's below 200 pM and activities 102-103 times more potent than the corresponding trifluoromethyl ketones. The potent inhibitors combine several features, viz.: 1.) an &agr;-keto heterocylic head group; 2.) a hydrocarbon linkage unit employing an optimal C12-C8 chain length; and 3.) a phenyl or other &pgr;-unsaturation corresponding to the arachidonyl &Dgr;8.9/&Dgr;11.12 and/or oleyl &Dgr;9.10 positions. A preferred &agr;-keto heterocylic head group is &agr;-keto N4 oxazolopyridine, with incorporation of a second weakly basic nitrogen. Fatty acid amide hydrolase is an enzyme responsible for the degradation of oleamide (an endogenous sleep-inducing lipid) and anandamide (an endogenous ligand for cannabinoid receptors).
