Compound class: Peptide or derivative
Comment: AUNP-12 is a small branched peptide inhibitor of the PD-1/PD-L1 pathway that was developed by Aurigene Discovery Technologies and is claimed in their patent WO2011161699A3 [1]. It interacts with PD-1 and prevents binding of both PD-L1 and PD-L2 [3]. It is composed of two linked peptide chains (sequence 1 SNTSESFKFRVTQLAPKAQIKE and sequence 2 SNTSESF), with a total of 29 amino acids. Peptidic antagonists of PD-1 binding by PD-L1/L2 such as AUNP-12 are being developed with the aim of overcoming the pharmacokinetic, manufacture and useage limitations of the current monoclonal antibody PD-1 pathway inhibitors, as well as reducing some of their severe immune-related adverse events [2].

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

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.

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.
