Catalog Number: 2387
Chemical Name: 4-[[6-Methoxy-2-(4-methoxyphenyl)-3-benzofuranyl]carbonyl]benzonitrile
Biological Activity
Potent CB1 receptor antagonist/inverse agonist (Ki = 141 nM) with greater than 70-fold selectivity over CB2 receptors (Ki > 10 μM). Structurally dissimilar from SR 141716A and AM 251. Shows weak binding to both 5-HT2 (Ki = 6.4 μM) and muscarinic receptors (Ki = 2.1 μM).

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?
