Treating Mental Diseases, Inflammation and Pain with Anandamides 

Anandamide (N-arachidonoylethanolamine) is thought to act as an endogenous cannabinoid neurotransmitter in vertebrate nervous systems. It binds to and activates cannabinoid receptors and simulates many distinctive effects typical of plant-derived or synthetic cannabinoid drugs. 

Biochemical evidence indicates that anandamide is produced in and released from neurons in an activity-dependent manner. Further, as expected of a signalling molecule, anandamide is short-lived its life-span is limited by uptake into neural cells and by enzymatic hydrolysis. Anandamide hydrolysis is catalyzed by the enzyme anandamide amidohydrolase, which converts anandamide to yield two inactive metabolites, arachidonate and ethanolamine. 

Anandamide amidohydrolase is likely to play an important role in the physiological degradation of anandamide. Three lines of evidence support this possibility. First, anandamide amidohydrolase is highly selective. Second, anandamide amidohydrolase is discretely distributed in the central nervous system, where its localization parallels that of cannabinoid receptors. 

Therefore, inhibition of anandamide amidohydrolase to increase the accumulation of anandamide at its sites of action is desirable as a potential therapeutic approach for the treatment or prevention of disorders such as mental diseases, inflammation and pain, including treatment or prevention of schizophrenia, mood disorders, anorexia, multiple sclerosis, spasticity and glaucoma.
