Catalog Number: 2327
Alternate Names: (S)-(-)-WIN 55,212
Chemical Name: [(3S)-2,3-Dihydro-5-methyl-3-(4-morpholinylmethyl)pyrrolo[1,2,3-de]-1,4-benzoxazin-6-yl]-1-naphthalenyl-methanone monomethanesulfonate
Biological Activity
Novel, low potency CB2 receptor silent antagonist and CB1 receptor partial inverse agonist. Competitively antagonizes effects of CP 55,940 (pA2 = 6.1) and SR 144528 (pEC50 = 5.3) at CB2 receptors and acts as a partial inverse agonist at CB1 receptors (pIC50 = 5.5). Displays modest activity at human melatonin MT1 and muscarinic M4 receptors, but is selective over several other GPCRs.

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?
