Catalog Number: 1027
Chemical Name: N-Phenyl-7-(hydroxyimino)cyclopropa[b]chromen-1a-carboxamide
Biological Activity
Group I metabotropic glutamate receptor antagonist (IC50 ~ 3 μM); 67 times more potent than (S)-4-carboxyphenylglycine (Cat. No. 0323). Also a positive allosteric modulator for mGlu4a; potentiates L-AP4-mediated inhibition of striatopallidal synaptic transmission in vitro. Displays antiParkinsonian effects in rats in vivo.

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?
