GtoPdb Ligand ID: 11502

Synonyms: Emovit® | ICI-58,834 | ICI-58834 | Qelbree®
Approved drug
viloxazine is an approved drug (FDA (2021))
Compound class: Synthetic organic
Comment: Viloxazine was originally described as a selective norepinephrine reuptake inhibitor (NRI), principally based on its ability to potentiate noradrenergic effects. It also modulates 5-HT (serotonin) activity, via antagonistic activity at 5-HT2B and agonistic activity at 5-HT2C receptors, and it increases extracellular 5-HT levels in the prefrontal cortex (PFC) [4]. Viloxazine's chemical structure is different from conventional tri- or tetra-cyclic antidepressants. The INN stipulates a racemic mixture of enantiomers. We show the structure without specified stereochemistry to represent the mixture. The hydrocholride salt (SPN-812) was progressed by Supernus Pharmaceuticals for attention deficit hyperactivity disorder (ADHD) in children and adults.

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
Viloxazine was used in some European countries as an antidepressant, but it was withdrawn from the market in the early 2000s. The FDA approved extended release viloxazine hydrochloride (Qelbree) as a treatment for ADHD in April 2021 [1]. This is indicated for 6-17 year old children.
