Catalog Number: 3621
Chemical Name: (S)-1-(2-Amino-2-carboxyethyl)-3-(2-carboxy-thiophene-3-yl-methyl)-5-methylpyrimidine-2,4-dione
Biological Activity
GLUK5 kainate receptor antagonist (IC50 = 130 nM); also blocks recombinant homomeric GLUK7 receptors. Displays 12,700-fold selectivity for GLUK5 over GLUK6. Exhibits no activity at mGlu group I or NMDA receptors at concentrations of up to 10 μM. Apparent KD value is 18 ± 4 nM for depression of kainate responses on the dorsal root.

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?
