Approved drug
triptorelin is an approved drug (FDA (2001))
Compound class: Peptide or derivative
Comment: As is the case with many peptide molecules, there is some ambiguity as to the stereochemistry of triptorelin, therefore the chemical structure shown here may vary slightly from that displayed on the resources linked to from the table above. The marketed formulations contain triptorelin pamoate (PubChem CID 25074469) or triptorelin acetate (PubChem CID 25080282).

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
Extended-release formulations containing triptorelin pamoate are approved for the treatment of various indications including advanced stage prostate cancer, endometriosis, uterine fibroids and GnRH-dependent central precocious puberty (CPP), and are also used in in vitro fertilization programs. TriptodurTM is an extended-release formulation administered at 6 month intervals for CPP.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Triptorelin is a peptide agonist analogue of gonadotropin-releasing hormone (GnRH). When given continuously triptorelin down-regulates GnRH receptor activity, thereby inhibiting the release of the gonadotrophins, LH and FSH. This results in a marked reduction of testicular (and ovarian) steroidogenesis.
