Catalog Number: 2555
Chemical Name: 1-(4-Aminophenyl)-3-methylcarbamyl-4-methyl-3,4-dihydro-7,8-methylenedioxy-5H-2,3-benzodiazepine hydrochloride
Biological Activity
Non-competitive AMPA and kainate receptor antagonist. Analog of GYKI 52466 (Cat. No. 1454). Prolongs the survival time after MgCl2- induced global cerebral ischemia. Exhibits anticonvulsant activity. Also blocks GluK3 homomeric receptors (IC50 = 63 μM) and GluK2b(R)/GluK3 heteroreceptors (IC50 = 32 μM) at high concentrations.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
