Catalog Number: 3678
Chemical Name: (3aS*,4R*,9bR*)-4-(6-Bromo-1,3-benzodioxol-5-yl)-3a,4,5,9b-3H-cyclopenta[c]quinoline
Biological Activity
High affinity and selective GPER receptor antagonist (Ki = 20 nM) that displays no affinity for ERα and ERβ at concentrations up to 10 μM. Inhibits agonist-induced calcium mobilization in vitro (EC50 of ~185 nM) and antagonizes the antidepressive and renoprotective effects of estrogen 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?
