Catalog Number: 2079
Chemical Name: (S)-1-(2-Amino-2-carboxyethyl)-3-(2-carboxybenzyl)pyrimidine-2,4-dione
Biological Activity
Potent and selective GLUK5 (GluR5)-subunit containing kainate receptor antagonist (apparent KD = 402 nM); active enantiomer of UBP 296 (Cat. No. 2078). Displays ~ 260-fold selectivity over AMPA receptors, ~ 90-fold selectivity over recombinant human GLUK6- and GLUK2-containing kainate receptors and has little or no action at NMDA or group I mGlu receptors. Selectively blocks kainate receptor-mediated LTP induction in rat hippocampal mossy fibers. Also protects against soman-induced seizures and neuronal degeneration for up to 30 days when administered one hour after soman exposure.

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?
