Catalog Number: 0644
Chemical Name: N-Cyclohexyl-4-(imidazol-4-yl)-1-piperidinecarbothioamide
Biological Activity
Potent histamine H3 and H4 antagonist/inverse agonist. Ki values are 25 and 27 nM for human recombinant H3 and H4 receptors respectively. Blocks eosinophil shape change (IC50 = 1.4 μM) and chemotaxis (IC50 = 519 nM) induced by histamine. Freely crosses the blood-brain barrier. Also available as part of the Histamine H3 Receptor Tocriset™.

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?
