Catalog Number: 4458
Chemical Name: N-(1,3-Diphenyl-1H-pyrazolo-5-yl)-4-nitrobenzamide
Biological Activity
Potent allosteric potentiator at the rat mGlu5 receptor (EC50 = 9 nM); binds to the MPEP (Cat. No. 1212) allosteric site (Ki app = 244 nM). Selective for mGlu5 over mGlu1 and mGlu2 receptors (EC50 values are 557 nM and 1.51 μM for mGlu1 and mGlu2 respectively). Potentiates both DHPG-induced LTP and threshold θ-burst stimulation (TBS)-induced LTP in rat hippocampal slices. Analog of CDPPB (Cat. No. 3235).

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?
