Catalog Number: 5161
Chemical Name: 3-(Diphenylphosphinothioyl)-2-methyl-1-[(2E)-3-phenyl-2-propen-1-yl]imidazo[1,2-a]pyridinium bromide
Biological Activity
Potent neuropeptide S receptor (NPSR) antagonist (pA2 = 9.98). Inhibits neuropeptide S-induced ERK phosphorylation over cAMP responses and calcium responses (IC50 values are 9.3, 22.1 and 36.5 nM, respectively). Appears to modulate addictive behavior in vivo. Displays no activity against vasopressin V1B receptors. Brain penetrant.

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?
