Galantamine

Galantamine is an alkaloid that has been found in Galanthus and has acetylcholinesterase (AChE) inhibitory and nicotinic acetylcholine receptor (nAChR) potentiating activities. It selectively inhibits AChE over butyrylcholinesterase (BChE, IC50s = 636 and 8,404 nM, respectively). Galantamine (0.5 µM) potentiates ACh-induced currents in HEK293 cells expressing human alpha4beta2 subunit-containing nAChRs. In vivo, galantamine (1.3 mg/kg per day) decreases escape latency and path length in the Morris water maze in the APP23 transgenic mouse model of Alzheimer's disease. Formulations containing galantamine have been used in the treatment of Alzheimer's disease.Formal Name: (4aS,6R,8aS)-4a,5,9,10,11,12-hexahydro-3-methoxy-11-methyl-6H-benzofuro[3a,3,2-ef][2]benzazepin-6-ol.
