Catalog Number: 4818
Chemical Name: 1-(4-Fluorobenzoyl)-3-[[(6-methoxy-2-naphthalenyl)oxy]methyl]-3-azetidinecarboxylic acid
Biological Activity
Potent EP2 receptor antagonist (IC50 = 16 nM for human EP2 receptors). Displays over 2000-fold selectivity for EP2 receptors over EP1, EP3, EP4, DP1 amd CRTH2 receptors; exhibits <30% binding at a diverse panel of GPCRs and ion channels at a concentration of 10 μM. Inhibits PGE2-induced increases in intracellular cAMP; reverses PGE2-invoked relaxation of mouse trachea (IC50 = 2.7 nM).

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?
