GtoPdb Ligand ID: 2055

Synonyms: DRG-0115 | Mycapssa® | Sandostatin® | SMS 201,995
Approved drug
octreotide is an approved drug (FDA (1988), EMA (2022))
Compound class: Peptide
Comment: Octreotide is a somatostatin mimetic.
As with many peptide molecules there is ambiguity around representations of the stereochemistry of octreotide. The chemical structure shown here does not specifiy stereochemistry and so may differ from representations on other chemical information resources in the Database Links table.

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.

Summary of Clinical Use Click here for help
Octreotide is used for the treatment of growth hormone producing tumours and pituitary tumours secreting thyroid stimulating hormone, and is used in nuclear medicine imaging of somatostatin receptor-expressing neuroendocrine tumours. In June 2020, an octreotide biosimilar (Mycapssa®, Amryt Pharmaceuticals) was FDA approved as long-term maintenance treatment for acromegaly patients who have responded to and tolerated treatment with octreotide or lanreotide. An equivalent approval for Mycapssa® was issued by the EMA in 2022.
