Catalog Number: 3060
Chemical Name: 9-(Dimethylamino)-3-(hexahydro-1H-azepin-1-yl)pyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4(3H)-one
Biological Activity
Potent, non-competitive mGlu1 receptor antagonist that displays 34-fold selectivity over mGlu5 (IC50 values are 10 and 342 nM respectively). Displays no significant activity at a range of other GPCRs, ion channels and transporters. Exhibits analgesic effects; decreases mechanical allodynia in models of neuropathic pain. Also impairs cognitive function.

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?
