GtoPdb Ligand ID: 9018

Synonyms: NCX 4016 | NCX4016 | nitric oxide-releasing aspirin | nitroaspirin
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: NCX-4016 is an inhibitor which supports generation of reactive oxygen species (ROS) that modify CCL2 levels, disabling T cell chemotaxis. It is expected that this type of action will have anti-inflammatory, antiproliferative, and cytoprotective activity [1]. NCX-4016 is a NO-NSAID type compound (nitric oxide-donating NSAID), a hybrid nitrate conjugated to an NSAID, in this case aspirin. This type of compound was designed to exploit the gastroprotective properties of NO bioactivity, to combat the gastrotoxicity which compromises NSAID use [2].

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
NCX-4016 reached Phase 2 clinical trial in patients with type 2 diabetes and early nephropathy (NCT00157508, terminated) and those with peripheral arterial occlusive disease (PAOD; NCT01256775, completed but not progressed). Despite showing positive results in pre-clinical testing [2] , these effects in colorectal cancer were not replicated in a Phase 1 trial (NCT01256775).
