Catalog Number: 0493
Alternate Names: RG-50810, Tyrphostin A23
Chemical Name: [(3,4-Dihydroxyphenyl)methylene]-propenedinitrile
Biological Activity
Inhibitor of epidermal growth factor receptor (EGFR) and platelet-derived growth factor receptor (PDGFR) kinase (IC50 values are 35 and 25 μM respectively). Inhibits EGF-stimulated cell proliferation. Also acts as a mitochondrial uncoupler that alters phosphorylation-dependent cell signaling.

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?
