Guvacine
Guvacine is a alpha,beta-unsaturated monocarboxylic acid that is nicotinic acid which has been hydrogenated at the 1-2 and 5-6 positions of the pyridine ring. It has a role as a plant metabolite and a GABA reuptake inhibitor. It is a beta-amino acid, a tetrahydropyridine, an alpha,beta-unsaturated monocarboxylic acid, a pyridine alkaloid and a secondary amino compound. Guvacine is a pyridine alkaloid found in the Areca nut (also known as the Betel nut). It is an experimental drug with no approved indication. Experimental studies are still being investigated to determine all of the physiological effects and mechanisms of action of guvacine. Currently it has been determined that guvacine is a specific GABA reuptake inhibitor with no significant affinity at GABA receptors.
