PDB Ligand
Compound class: Synthetic organic
Comment: TAK-580 (MLN2480) is an investigational pan-RAF kinase inhibitor that was developed for anti-tumour potential against solid tumours, including gliomas, and common adult RAF mutant tumours (harbouring BRAF and CRAF fusions and mutations) that metastasise to the brain. It has been optimised for CNS penetration [2]. The chemical structure is claimed as example 10Da in patent US20090036419A1 [1]. Day One Biopharmaceuticals licensed this inhibitor from Sunesis Pharma in 2019, at which point it was re-named DAY101. The chemical structure of TAK-580 is identical to that which was submitted to the WHO for the INN tovorafenib (proposed INN list 126, Jan 2022).

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
TAK-580 functions as an effective inhibitor of BRAFV600E and KIAA1549:BRAF, a truncation/fusion BRAF oncoprotein which is active as a dimer and drives the most common form of pediatric low-grade astrocytomas [2]. It has low potency towards wild type BRAF, but is more potent against the kinase activities of BRAFV600E (IC50 248 nM) and KIAA1549:BRAF (IC50 190 nM).
