Catalog Number: 3863
Alternate Names: CP 99219
Chemical Name: 7-[(1α,5α,6α)-6-Amino-3-azabicyclo[3.1.0]hex-3-yl]-1-(2,4-difluorophenyl)-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid mesylate
Biological Activity
Fluoroquinolone antibiotic. Inhibits bacterial DNA topoisomerase IV and DNA gyrase and forms a stable quinolone-DNA complex with these enzymes which reversibly inhibits DNA synthesis. Displays potent activity against gram-positive and gram-negative bacteria. Increases the production of mitochondrial NO in immortalized hepatocytes; also increases mitochondrial Ca2+. Inhibits Panx-1 (IC50 ~ 4μM).

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?
