GtoPdb Ligand ID: 7739

Synonyms: AF802 | Alecensa® | CH5424802
Approved drug PDB Ligand
alectinib is an approved drug (FDA (2015), EMA (2017), Japan (unknown))
Compound class: Synthetic organic
Comment: Alectinib is a second generation ALK inhibitor. It was developed to inhibit the expression of the mutated ALK gene that causes growth of some non-small cell lung cancers, in patients whose cancer has become resistant to the older ALK inhibitor, crizotinib [2,5]. However, additional mutations may develop which confer alecitinib resistance [1]. Cells harbouring these novel mutations are reported to be sensitive to ceritinib and other next-generation ALK tyrosine kinase inhibitors [1]. The identification of the mechanisms by which acquired tumour resistance occurs highlights the importance of being able to use the correct drug for the correct patient to maximise the clinical benefit [4]
The design and synthesis of alectinib (CH5424802) is described in [2].

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.
