Catalog Number: 4079
Chemical Name: 5-Chloro-N-(2-chloro-4-nitrophenyl)-2-hydroxybenzamide
Biological Activity
Inhibitor of the STAT3 signaling pathway; inhibits the activation, nuclear translocation and transactivation of STAT3. Displays selectivity for STAT3 over STAT1, STAT5, JAK1, JAK2 and Src kinases. Inhibits the transcription of STAT3 target genes and induces cell growth inhibition, apoptosis and cell cycle arrest of cancer cells with constitutively active STAT3. Also reversibly inhibits mTORC1 signaling and stimulates autophagy in vitro; displays antineoplastic effects in acute myelogenous leukemia (AML) stem cells.

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?
