GtoPdb Ligand ID: 9196

Synonyms: BI-1482694 | Example 1 [US20130116213] | HM-61713 | HM61713
Approved drug
olmutinib is an approved drug (South Korea (2016))
Compound class: Synthetic organic
Comment: Olmutinib from Hanmi Pharmaceutical, approved in South Korea for lung cancer, targets mutant epidermal growth factor receptor (EGFR) selectively over wild-type. It is reported as an oral, third-generation EGFR tyrosine kinase inhibitor (binding covalently), however there is no published, peer-reviewed data to confirm this. The potential for using third-generation EGFR inhibitors in EGFR-mutated non-small lung cancer is reviewed by Russo et al. (2017) [7]. Olmutinib is claimed in patent WO2011162515 [1]. Full text descriptions and structure images are available in US20130116213 [3], where it is identified as Example 1 (N-(3-(2-(4-(4-methylpiperazin-1-yl)phenylamino)thieno[3,2-d]pyrimidin-4-yloxy)phenyl)acrylamide). Note we updated this entry in Nov 2016 with the removal of the incorrect synonyms HM-71224 and LY3337641 which refer to a blinded Hanmi BTK inhibitor [4].

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
No technical papers have yet appeared (Nov 2016) but the Hanmi patent [1] includes binned IC50 data for 150 analogues. Olmutinib is recorded as having <50nM for inhibition of EGFR with L858R/T790M mutation, two other mutations and 100-1000nM for wild type EGFR . In these biochemical assays olmutinib was more selective for the mutant EGFR than erlotinib. Inhibition data for cancer cell lines is also provided, with GI50 values of <50nM vs. cells with DelE746_A750 or L858R/T790M EGFR mutations, and >1000nM for cells with wild type EGFR.
