Catalog Number: 3350
Chemical Name: 1-[2-[4-(6-Fluoro-1H-indol-3-yl)-3,6-dihydro-1(2H)-pyridinyl]ethyl]-3,4-dihydro-3-(1-methylethyl)-6-(methylsulfonyl)-1H-2,1,3-benzothiadiazine-2,2-dioxide
Biological Activity
Dual 5-HT1B/1D receptor antagonist (pKB values are 9.05 and 8.98 respectively) and 5-HT re-uptake inhibitor (pIC50 = 8.48). Potently antagonizes terminal autoreceptor activity in vitro and increases extracellular 5-HT levels above those evoked by fluoxetine (Cat. No. 0927) in vivo. Also acts as an antagonist at 5-HT2A and 5-HT2B receptors (pKi values are 7.29 and 7.35 respectively).

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?
