Catalog Number: 3249
Chemical Name: cis-(±)-1-Amino-3-phosphonocyclopentane carboxylic acid
Biological Activity
Group III mGlu receptor agonist that exhibits higher potency at mGlu4 than mGlu8 (EC50 values are 49 and 124 μM respectively) with no activity at mGlu7. Selectively inhibits synaptic activity in the lateral perforant pathway (IC50 values are 130 and 1859 μM in the lateral and medial perforant pathways respectively). Conformationally restrained analog of L-AP4 (Cat No. 0103).

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?
