Description
In Vitro
M40 (1 μM) displaces [mono[125IJodo-Tyr26]galanin from binding sites in the hippocampus, hypothalamus, and spinal cord. M40 has a lower affinity than galanin for all membranes. The IC50 values are 6 nM in the hippocampus, 15 nM in the hypothalamus, 12 nM in the spinal cord, and 3 nM in the insulinoma cells. M40 (1 μM) completely blocks 125I-labeled galanin-binding sites[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. .
In Vivo
M40 (2-8 nmol, intraventricular or intrahippocampal, single dose) exhibits antagonist efficacy against galanin on memory tasks in sprague-dawley rats models, exhibits potency in alleviating the cognitive deficits associated with Alzheimer's disease[2].
