GtoPdb Ligand ID: 7896

Synonyms: 19-IIIa [3] | Debio 0827 [1] | Debio-0827
Compound class: Synthetic organic
Comment: PL37 is an investigational, orally available, dual pro-drug inhibitor of neprilysin (a.k.a. neutral endopeptidase or NEP; MME) and aminopeptidase N (APN; ANPEP) [3]. NEP and APN are enkephalin catabolising enzymes (or enkephalinases). Dual ENKephalinase inhibitors such as this one have been ascribed the acronym DENK inhibitor (or DENKi).
PL37 is the non-stereo enantiomer of compound 15 in patent US8247609 [4]. Such dual inhibitors are suggested as a novel mechanism for the control of central and peripheral pain [5], via inhibition of enzymatic degradation of endogenous enkephalins. Such agents could replace the use of opiate analgesics.

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.
