Description | Galanthamine hydrobromide (Galantamine hydrobromide), a long-acting and centrally active AChE inhibitor (IC50:410 nM), is an allosteric potentiator at neuronal nicotinic ACh receptors. |
Targets&IC50 | AChE:410 nM |
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 | 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] |
