Catalog Number: 5671
Chemical Name: 6-Chloro-3-[[[(2,3-dichlorophenyl)amino]carbonyl]amino]-2-hydroxybenzenesulfonamide
Biological Activity
Potent CXCR2 antagonist (IC50 = 7.7 nM). Exhibits 285-fold selectivity for CXCR2 over CXCR1. Reduces leukocyte numbers in synovial fluid in acute and chronic rabbit arthritis models. Also reduces synovial fluid eicosanoid and cytokine levels in a rabbit chronic arthritis model. Inhibits proliferation of AML cells lines in vitro.

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?
