Catalog Number: 3115
Chemical Name: 2-Bromo-4-[(6,7-dimethoxy-4-quinazolinyl)amino]phenol
Biological Activity
JAK3 inhibitor (IC50 = 1.8 μM) that displays no activity at JAK1 or JAK2. Inhibits STAT1 activation, iNOS expression and NO production in macrophages in vitro. Also inhibits other common kinases including EGFR (IC50 = 4 nM), Src, Abl, VEGFR, MAPK and PI 3-K and induces apoptosis in human glioblastoma cell lines (IC50 = 158 μM). Induces differentiation of neural progenitor 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?
