Galanthamine HBr | Acetylcholinesterase inhibitor

Galanthamine HBr (1953-04-4) is a long-acting, centrally active acetylcholinesterase inhibitor, IC50 = 410 nM1. Allosteric potentiator at neuronal nicotinic ACh receptors2. Prevents β-amyloid-induced apoptosis in SH-SY5Y and bovine chromaffin cells3. Galanthamine HBr is a clinically useful agent for symptomatic relief of Alzheimer's disease but fails to prevent progression of the disease4,5.
