Catalog Number: 2718
Alternate Names: HTS 466284
Chemical Name: 4-[3-(2-Pyridinyl)-1H-pyrazol-4-yl]-quinoline
Biological Activity
Selective inhibitor of TGF-β type-I receptor (TGF-β RI, TGFR-I, TβR-I, ALK-5) (IC50 values are 59, 400 and 1400 nM for TGR-β RI, TGF-β RII and MLK-7K respectively). Inhibits TGF-β-dependent luciferase production in mink lung cells (p3TP lux) and growth in mouse fibroblasts (NIH 3T3) (IC50 values are 47 and 89 nM respectively). Suppresses invasion of MDA-MB-231 breast cancer cells in a matrigel invasion assay.

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?
