Catalog Number: 3650
Chemical Name: N-(1-Naphthalenylcarbonyl)-4-nitro-L-phenylalanine methyl ester
Biological Activity
Potent and selective CCR3 antagonist (IC50 = 4 nM). Displays > 2500-fold selectivity over C5aR, LTD4, CCR7, CXCR1 and CXCR2 receptors. Inhibits eotaxin-, eotaxin-2- and MCP-4-induced Ca2+ mobilization (IC50 values are 38, 35 and 20 nM respectively) and inhibits eotaxin-, eotaxin-2- and MCP-4-induced eosinophil chemotaxis with similar potencies.

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?
