Galantamine-d3 is intended for use as an internal standard for the quantification of galantamine by GC- or LC-MS. Galantamine is an alkaloid originally isolated from the bulbs and flowers of Galanthus that inhibits acetylcholinesterase (AChE; IC50 = 636 nM).1 It reverses growth inhibition and inhibits apoptosis, autophagic flux, and production of reactive oxygen species (ROS) induced by amyloid-β (Aβ) in neuronally differentiated PC12 cells.2 Galantamine prevents soman toxicity and inhibits acetylcholinesterase in cynomolgus macaques (ED50s = 590 and 362 μg/kg, respectively).3 It also decreases escape latency in the Morris water maze and the total hippocampal area of Aβ plaques in an APP/PS1 transgenic mouse model of Alzheimer's disease.4
