abstract：:We investigated the inhibition of human cholinesterases by galanthamine, an alkaloid of the common snowdrop (galanthus nivalis). In vitro, the compound showed potent enzyme inhibition and 50-fold selectivity for acetylcholinesterase (EC 3.1.1.7) as opposed to butyrylcholinesterase (EC 3.1.1.8). There was no difference...
