Catalog Number: 3439
Chemical Name: 1-Hexadecyl-2-methyl-3-(phenylmethyl)-1H-imidazolium iodide
Biological Activity
Eukaryotic elongation factor 2 (eEF-2) kinase (CaMK III) inhibitor (IC50 = 60 nM) that displays 125-fold, > 1300-fold and > 1500-fold selectivity over PKC, PKA and CaMK II respectively. Decreases the viability of a variety of cancer cell lines (IC50 values are 0.7 - 4.8 μM) and blocks G1/S cell cycle progression. Shown to induce eEF-2 phosphorylation in cancer cells. Also an effective antibacterial agent; inhibits histidine protein kinase in vitro (IC50 = 6.6 μM) and in vivo.

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?
