GtoPdb Ligand ID: 10056

Synonyms: OLT-1177 | OLT1177
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Dapansutrile (OLT1177) acts as a NLRP3 inflammasome inhibitor. It is a clinical candidate that is being developed by Olatec Therapeutics. Inhibition of the NLRP3 inflammasome reduces maturation of the pro-inflammatory, disease-associated cytokines IL-1β and IL-18 [3]. Immunoprecipitation and FRET analysis indicates that OLT1177 inhibits inflammasome oligomerization by blocking NLRP3-ASC, and NLRP3-caspase-1 interaction, but may also directly target NLRP3 (as assessed by inhibition of recombinant NLRP3 ATPase activity by dapansutrile) [3].

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.
