Catalog Number: 2255
Alternate Names: Zaldaride maleate
Chemical Name: 1,3-Dihydro-1-[1-[(4-methyl-4H,6H-pyrrolo[1,2-a][4,1]benzoxazepin-4-yl)methyl]-4-piperidinyl]-2H-benzimidazol-2-one maleate
Biological Activity
Calmodulin antagonist; inhibits calmodulin-stimulated cAMP phosphodiesterase activity with an IC50 of 3.3 nM. Also prevents estrogen-induced transcription activation by ER, reversibly blocks voltage-activated Na+, Ca2+ and K+ currents in PC12 cells and inhibits nAChR.

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?
