GtoPdb Ligand ID: 10884

Synonyms: AZP-531 | AZP531 | Cyclo(des-acyl ghrelin(6-13)) | Des-acyl ghrelin
Compound class: Peptide
Comment: Livoletide (AZP-531) is a first-in-class analogue of unacylated ghrelin (UAG) [2]. The exact mechanism of action is still unclear. When UAG is co-administered with ghrelin it is reported to act either as a functional antagonist or is acting via another receptor [2,4]. Other studies suggest that UAG is a full agonist [3].

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.
