Catalog Number: 4518
Chemical Name: N-(3-Ethoxyphenyl)-4-(1-pyrrolidinyl)-3-(trifluoromethyl)benzamide
Biological Activity
Trace amine 1 (TA1) receptor antagonist/inverse agonist; exhibits a higher potency at the mouse TA1 receptor than the rat and human TA1 receptors (IC50 values are 27.5, 4539 and 7487 nM, respectively). Blocks the TA1 receptor-mediated activation of an inwardly rectifying K+ current, which increases the firing frequency of dopamine (DA) neurons in the ventral tegmental area. Increases DA potency at the D2 receptor. Also displays inverse agonism, reducing basal cAMP levels in vitro (IC50 = 19 nM).

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?
