GtoPdb Ligand ID: 7135

Synonyms: amfebutamone | BW-323 | Wellbutrin® | Zyban®
Approved drug
bupropion is an approved drug (FDA (1985))
Compound class: Synthetic organic
Comment: The approval status for use of this drug was submitted for re-evaluation by the European Medicines Agency in 2002, following public health concerns around serious adverse reactions associated with its use. These included depression, suicidal thoughts, suicide, seizures, undesirable cardiovascular effects, and angioedema. EU Member States regulatory authorities agreed to keep the product under regular review.
Marketed formulations usually contain bupropion hydrochloride (PubChem CID 62884).

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 Chemistry Development Kit (CDK) (Willighagen EL et al. Journal of Cheminformatics vol. 9:33. 2017, doi:10.1186/s13321-017-0220-4; https://cdk.github.io/). 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
Bupropion is used to aid smoking cessation (in combination with motivational support) in nicotine-dependent patients. Some countries authorise use for additional indications eg major depressive disorder in the US and Canada and seasonal affective disorder in Canada.
In September 2014 the US FDA approved Contrave® (bupropion and naloxone), a fixed-mixture medication, to be used in conjunction with reduced-calorie intake and physical activity, as a treatment for chronic weight management.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
The mode of action of bupirion in smoking cessation is not completely understood., but appears to involve inhibition of serotonin and dopamine reuptake.
