Catalog Number: 5061
Chemical Name: N-[(3-Hydroxyphenyl)methyl]-N'-[4-(4-pyridinyl)-2-thiazolyl]urea dihydrochloride
Biological Activity
Potent and selective ROCK inhibitor (IC50 values are 6.2 and 14.5 nM for ROCK2 and ROCK1 respectively); suppresses phosphorylation of ROCK substrates MLC-2 and MYPT-1 in human cancer cells, but has no effect on the phosphorylation levels of Akt, MEK, and S6 kinase. Displays anti-invasive and antitumor activities in breast cancer 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?
