Catalog Number: 5281
Alternate Names: XBD173
Chemical Name: N-Ethyl-7,8-dihydro-7-methyl-8-oxo-2-phenyl-N-(phenylmethyl)-9H-purine-9-acetamide
Biological Activity
Ligand of translocator protein (TSPO, peripheral benzodiazepine receptor). Exhibits high affinity for TSPO in rat whole brain (Ki = 0.297 nM), and high potency against human and rat glial TSPO (IC50 values are 2.73 and 3.04 nM respectively). Displays no noticeable binding to a number of other receptors, transporters or ion channels. Also displays anxiolytic and antidepressant effects in rodent models, without inducing benzodiazepine-like adverse effects.

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?
