Catalog Number: 3221
Chemical Name: 1,1'-(1,12-Dodecanediyl)bis[3-methylpyridinium] dibromide
Biological Activity
Orthosteric neuronal nicotinic acetylcholine receptor (nAChR) antagonist (IC50 values are 0.17, 0.25, 0.4, 4.8, 6.5, 8.2, 20 and 34 μM at α3β4, α1β1εδ, α3β4β3, α6β4β3, α7, α4β2, α3β2β3 and α6/3β2β3 receptors respectively). Attenuates nicotine-evoked dopamine release from the ventral tegmental area in vivo (IC50 = 0.2 nM) and reduces nicotine self-administration in rats. Brain penetrant.

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?
