GtoPdb Ligand ID: 10476

Synonyms: BAY 57-9352 | Bay-57-9352 | BAY-579352 | BAY579352 | example 14 [WO2001023375A2]
Compound class: Synthetic organic
Comment: Telatinib (BAY-579352) is an orally available VEGFR2/3 and PDGFRβ receptor tyrosine kinase inhibitor that exhibits potent anti-angiogenic activity which translates to anti-tumour efficacy in vitro and in vivo. The chemical structure of telatinib is claimed in Bayer's patent WO2001023375A2 (as example 14) [1].

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.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the CDK toolkit. All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

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.

Bioactivity Comments
Telatinib is not directly active against tumour cells, but is antiproliferative vs. HUVEC cells in vitro, which indicates a purely antiangiogenic mechanism of action. A J Med Chem article by Musumeci et al. provides IC50 values for telatinib vs. VEGFR2 and VEGFR3 (6 and 4 nM respectively) but the source of these values is unclear [5]. The VEGFR2 IC50 of 6 nM in Lee et al. (2010) was estimated in a virtual screening study, and was not validated in an in vitro follow-up experiment [3]. As an alternative we provide an IC50 from Bayer's patent.
