Catalog Number: 2976
Chemical Name: 5-(4-Chlorophenyl)-N-(3,5-dimethoxyphenyl)-2-furancarboxamide
Biological Activity
Selective blocker of NaV1.8 channels (IC50 values are 8, 2450, 6740, 7340 and 7380 nM for hNaV1.8, hNaV1.3, hNaV1.7, hNaV1.5 and hNaV1.2 channels respectively). Shows no significant activity against TRPV1, P2X2/3, CaV2.2 and KCNQ2/3 channels. Antinociceptive; potently attenuates mechanical allodynia in two models of neuropathic pain following i.p. administration.

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?
