Galanthamine HBr

Research use only, not for human use.

Galanthamine hydrobromide is a long-acting, centrally active acetylcholinesterase(AChE) inhibitor (IC50 = 410 nM) and allosteric potentiator at neuronal nicotinic ACh receptors.

Galanthamine hydrobromide is a long-acting, centrally active acetylcholinesterase(AChE) inhibitor (IC50 = 410 nM) and allosteric potentiator at neuronal nicotinic ACh receptors.(In Vitro):Galanthamine hydrobromide is 53-fold selectivity for AChE over butyrylcholinesterase.Galanthamine hydrobromide (25-1000 μM) inhibits both Aβ 1-40 (50 μM) and Aβ 1-42 (50 μM) aggregation.Galanthamine hydrobromide (25-1000 μM) protects against Aβ(1-40) and Aβ(1-42) toxicity in SH-SY5Y cells.Galanthamine hydrobromide also dramatically reduces Aβ(1-40)-induced cellular apoptosis.(In Vivo):Galanthamine hydrobromide (1.25-2.5 mg/kg; i.p. ) reduces cognitive deficits in APP23 mice.Galanthamine hydrobromide (10 mg/kg; i.g.) displays short elimination half-life of approximately 2 h in wild-type mice.
