Catalog Number: 0589
Chemical Name: 2-(4-Morpholinethyl) 1-phenylcyclohexanecarboxylate hydrochloride
Biological Activity
High affinity, selective σ1 agonist (Ki values are 2.2 and 13091 nM for σ1 and σ2 receptors respectively). Selective over PCP receptors (IC50 > 100000 nM) and several other receptor systems. Produces antiamnesic and antitussive effects in vivo. Also exhibits protective effects in PC6.3 cells expressing mutant huntingtin by activating NF-κB signaling.

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?
