Catalog Number: 4963
Chemical Name: 2-(7-Fluoropyrrolo[1,2-a]quinoxalin-4-yl) 2-pyrazinecarboxylic acid hydrazide hydrochloride
Biological Activity
Inhibitor of gp130 (IC50 = 0.72 μM); blocks cytokine-triggered gp130 signaling. Induces gp130 phosphorylation and down regulates gp130 glycosylation; also abrogates STAT3 phosphorylation, nuclear translocation and inhibits the expression of downstream target genes. Delays tumor growth in a mouse xenograft model of human ovarian cancer. Orally active.

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?
