Catalog Number: 5866
Chemical Name: (-)-3-[3-Bromo-4-[(2,4-difluorophenyl)methoxy]-6-methyl-2-oxo-1(2H)-pyridinyl]-N,4-dimethylbenzamide
Biological Activity
Potent and selective p38α/β inhibitor (IC50 values are 26 and 102 nM, respectively). Exhibits >100-fold selectivity for p38α/β over 71 other kinases, enzymes and GPCRs, including p38γ, p38δ, JNK and ERK2. Inhibits LPS-induced TNFα production in U937 monocytes in vitro. Suppresses acute and chronic inflammatory responses in rat models of arthritis. Orally active.

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?
