Catalog Number: 2132
Alternate Names: DAN 2163
Chemical Name: 4-Amino-N-[(1-ethyl-2-pyrrolidinyl)methyl]-5-(ethylsulfonyl)-2-benzamide
Biological Activity
Potent, selective dopamine D2 and D3 receptor antagonist. Ki values are 2.8 and 3.2 nM respectively for human D2 and D3 and > 1000 nM for human D1, D4 and D5 receptors. Shows selectivity for presynaptic dopamine autoreceptors at low doses and blocks postsynaptic D2/D3 receptors at higher doses. Preferentially interacts with limbic D2-like receptors in vivo. Atypical antipsychotic/antischizophrenic agent with limited extrapyrimidal side effects and a profile distinct from that of haloperidol and remoxipride.

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?
