GtoPdb Ligand ID: 5484

Synonyms: (S)-pregabalin | CI 1008 | Lyrica® | Nervalin® | PD 144723
Approved drug
pregabalin is an approved drug (FDA and EMA (2004))
Compound class: Synthetic organic
Comment: Pregabalin is a gabapentinoid class anti-seizure medication. Chemically, it is a 3-isobutyl derivative of the inhibitory neurotransmitter γ-aminobutyric acid (GABA), but it appears to function as a modulator of voltage-gated calcium channels, rather than a GABA receptor agonist.

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
Used to treat generalised anxiety disorder (GAD) and in the management of neuropathic pain associated with diabetic peripheral neuropathy or spinal chord injury, and post herpetic neuralgia. Also used in the management of fibromyalgia and as an adjunctive therapy for partial onset seizures.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Like gabapentin, pregabalin likely acts, at least in part, via inhibition of the α2δ subunit (CACNA2D1, P54289) of the VGCC. Some evidence exists to support the hypothesis that compounds such as pregabalin and gabapentin don't actually block presynaptic calcium channels, but rather exert an inhibitory effect on the re-cycling of the channels from endosomal pools back to the plasma membrane via interaction with intracellular δ subunits [1].
