GtoPdb Ligand ID: 8290

Synonyms: NMS-E628 | Rozlytrek® | RXDX-101
Approved drug PDB Ligand
entrectinib is an approved drug (Japan and FDA (2019), EMA (2020))
Compound class: Synthetic organic
Comment: Entrectinib is an oral, brain penetrant, receptor tyrosine kinase (RTK) inhibitor that targets solid tumours that harbour activating alterations in NTRK1, NTRK2, NTRK3 (the Trk family RTKs), ROS1 or ALK [6]. NTRK1 fusion proteins are becoming recognised as oncogenic-drivers in NSCLC [3], so the ability of the compound to target these and ALK- and ROS1-rearrangements suggests it has the potential to become a useful oncology agent.
More recently entrectinib has been shown to inhibit NLRP3 inflammasome assembly and activation via a direct interaction with NIMA related kinase 7 (NEK7) that disrupts the NLRP3-NEK7 interaction [5]. This discovery suggests a role for entrectinib as an intervention for inflammasome-related diseases.

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 Chemistry Development Kit (CDK) (Willighagen EL et al. Journal of Cheminformatics vol. 9:33. 2017, doi:10.1186/s13321-017-0220-4; https://cdk.github.io/). 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
Thus far in vitro and in vivo activity has only been reported in meeting abstracts (see references 71-73 in [2], or generated via PubChem Bioassay. PubChem Bioassay results report Ki values of 1nM (ALK), 1.58nM (TrkA, NTRK1), 2.51nM (TrkB, NTRK2) and 1.58nM (TrkC, NTRK3).
Entrectinib inhibits IL-1β formation (a proxy for NLRP3 inflammasome activation) by ~95% (at 10μ M in vitro [5].
