GtoPdb Ligand ID: 963

Synonyms: (±)-amisulpride | Barhemsys®
Approved drug
amisulpride is an approved drug
Compound class: Synthetic organic
Comment: The approved drug amisulpride is a racemic mixture of (+)-amisulpride and (-)-amisulpride. The structure shown here does not specify stereochemistry and represents the mixture. The links to external resources in the table above all match the INN-assigned compound amisulpride without stereochemistry specified. Alternative stereoisomers are represented by CID 5746246 and CID 3055076.

The INN-assigned compound sultopride has a similar but distinct structure to amisulpride; however the nomenclature for these two compounds is sometimes used interchangeably on other resources.

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the CDK toolkit. All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Summary of Clinical Use Click here for help
This drug is an atypical antipsychotic used to treat psychosis in schizophrenia and manic episodes of bipolar disorder. However, there is no information regarding approval for use of this drug for these indications on the US FDA or European Medicines Agency websites. Other national approval agencies may have granted marketing authorisation for use in these conditions.

In February 2020 the FDA granted approval for amisulpride injection (Barhemsys) to be used to help prevent postoperative nausea and vomiting.
Amisulpride causes dose- and concentration-dependent QT prolongation, so caution is advised for patients with pre-existing medical conditions or who are taking other medications, that are known to prolong the QT interval. Avoid use of amisulpride in patients with congenital long QT syndrome or who are taking droperidol.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Amisulpride is primarily an antagonist of the dopamine D2 and D3 receptors.
