Biological Activity

Description Galanthamine is an AChE inhibitor with IC50 of 0.35 μM, exhibits 50-fold selectivity against butyryl-cholinesterase.
Targets
AChE [1]
0.35 μM
In vitro
In vitro Galanthamine has been demonstrated to have an IC50 of 14 nM and 15 nM on AChE in post-mortem human brain frontal cortex and the hippocampus region. Red-cell cholinesterase activity in blood samples from the neurosurgery patients is 10 times more strongly inhibited by Galanthamine in brain tissue samples. [1] Galanthamine (1 μM) activates single channels with conductance's of 18 and 30 pS in outside-out patches excised from dexamethasone mouse fibroblasts (M10 cells). [2] Galanthamine acts as noncompetitive nicotinic receptor agonists' on clonal rat pheochromocytoma (PC12) cells. Galanthamine (50 μM) activates single-channel currents in outside-out patches excised from clonal PC12 cells. [3]
In Vivo
In vivo Galantamine significantly increases the number of living pyramidal neurons after ischemia-reperfusion injury. Galantamine significantly reduces TUNEL, active caspase-3, and SOD-2 immunoreactivity. The nicotinic antagonist mecamylamine blockes the protective effects of galantamine. The neuroprotective effects of galantamine are preserved even when first administered at 3 hours postischemia. [4]
Animal Research Animal Models Gerbils
Dosages 10 mg/kg
Administration S.c. twice a day or 3 or 6 hours after ischemia and at subsequent 12-hours intervals until sacrifice

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
