GtoPdb Ligand ID: 7906

Synonyms: INNO-406 | Lyn-IN-1 | NS-187
PDB Ligand Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Bafetinib is a second-generation, dual Lyn/Abl kinase inhibitor [1,6] with therapeutic.potential for the treatment of imatinib-resistant or -intolerant B-cell chronic lymphocytic leukemia (CLL), and prostate cancer. Data indicate that bafetinib crosses the blood-brain-barrier, reaching therapeutic concentration, so the drug's potential for treatment of brain tumours is also under investigation.

Note that we have mapped the chemical structure using the updated CAS registry number stipulated in INN proposed list 101 (2009) to the CID specified here, but the name maps to four other CIDs in PubChem.

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.

Summary of Clinical Use Click here for help
Bafetinib has been assessed in two completed Phase 2 clinical trials for hormone-refractory prostate cancer (NCT01215799) and relapsed or refractory B-cell chronic lymphocytic leukemia (CLL; NCT01144260).
Both the US FDA and EMA have granted bafetinib orphan drug status for the treatment of Philadelphia chromosome-positive CML.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Bafetinib specifically binds to and inhibits the Bcr/Abl fusion protein tyrosine kinase, an abnormal enzyme produced by Philadelphia chromosomal translocation associated with chronic myeloid leukemia (CML) [5]. It also inhibits the Src-family member Lyn tyrosine kinase, upregulated in imatinib-resistant CML cells and in a variety of solid cancer cell types [4]. The inhibitory effect of bafetinib on these kinases may decrease cellular proliferation and induce apoptosis in tumor cells driven by their overexpression [2].
