GtoPdb Ligand ID: 9609

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: This is the most potent compound developed via a pharmacophore and docking-based virtual screening campaign aimed at the discovery of small molecule inhibitors of the IL-15/IL-15R interaction [2]. Specifically, the investigators were searching for compounds that inhibit IL-15 binding to the IL-2Rβ subunit which together with the γ subunit, forms the signal transducing component of the IL-15R complex. Although the compound was found to be non-selective for IL-15 over IL-2, as a first in vitro SAR study it provides crucial information on the key binding interactions of IL-15 with its IL-2Rβ binding site, that will be useful for futher compound optimisation.

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.
