GtoPdb Ligand ID: 8523

Synonyms: cyclo[1-6]CRPRLCHKGPMPF
Compound class: Peptide or derivative
Comment: MM07, is a cyclic peptide agonist of the apelin receptor that is more stable than the endogenous apelin peptide. It acts as a biased agonist at the apelin receptor, that can preferentially stimulate the G protein pathway. It was hypothesised that this biased action could translate to improved efficacy in vitro by selectively stimulating vasodilatation and inotropic actions, whilst avoiding activation of detrimental β-arrestin-dependent pathways.

We generated the HELM annotation and SMILES for MM07 using HELM Editor v1.4 (from Pistoia Alliance).

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.
