Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Lonodelestat is a modified cyclic peptide (macrolide) that acts as a selective inhibitor of human neutrophil elastase (hNE). It is being developed by Santhera Pharmaceuticals, under license from its originator Polyphor. In April 2020 Santhera announced a COVID-19 collaboration, in which non-clinical research will be conducted by Cold Spring Harbor Laboratory (CSHL) to further validate hNE as a target and assess lonodelestat as a potential agent for treating COVID-19-related acute respiratory distress syndrome (ARDS).

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.

Immunopharmacology Comments
Neutrophil elastase activity is associated with inflammation in the lungs, and its effects are damaging to lung tissue. Inhibiting neutrophil elastase function may minimise tissue destruction and decrease airway inflammation in diseases that are characterised by predominantly neutrophil-mediated inflammation.
