Catalog Number: 2507
Chemical Name: (αR)-α-Cyclopentyl-α-hydroxy-N-[1-(4-methyl-3-pentenyl)-4-piperidinyl]benzeneacetamide fumarate
Biological Activity
Potent M3 muscarinic receptor antagonist that displays ~ 120-fold selectivity over M2 receptors (Ki values are 4.2, 19 and 490 nM for human M3, M1 and M2 receptors respectively). Exhibits > 250-fold bronchial selectivity; inhibits ACh-induced bronchoconstriction but not ACh-induced bradycardia (KB values are 3.3 and 170 nM for rat trachea M3 and rat right atria M2 receptors respectively).

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?
