GtoPdb Ligand ID: 10645

Synonyms: GS-0976 | GS-ACC | ND 630 [4] | ND-630 | NDI-010976
Compound class: Synthetic organic
Comment: Firsocostat (GS-0976) is a liver-directed acetyl-CoA carboxylase (ACC) inhibitor [2]. It was initially identified by Nimbus Therapeutics [3], and is being developed by Gilead as an antilipemic agent for potential to treat non-alcoholic steatohepatitis (NASH) [1]. Firsocostat is an allosteric inhibitor that binds to the ACC biotin carboxylase dimerization site, rather than to the previously targeted carboxyltransferase domain. The firsocostat-ACC interaction mimics the physiological inhibition of ACC by AMPK.

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.

Bioactivity Comments
In the mouse model of NASH (MC4R knockout) pharmacological inhibition of ACC1/2 by firsocostat (GS-0976) improves hepatic lipid metabolism and ameliorates steatosis and hepatic fibrosis [6]. This effect is also observed in human clinical trial patients [5]. ACC1 and ACC2 are both inhibited by firsocostat. GS-0976-mediated ACC inhibition is highly specific for ACC; no effect on the activity of 101 enzymes, receptors, growth factors, transporters, and ion channels in the Ricerca DrugMatrix screening panel was detected [3]. Since the allosteric binding site for firsocostat is not present (conserved) in other mammalian carboxylases it does not inhibit these mechanistically related enzymes.
