Synonyms: INNO-406 | Lyn-IN-1 | NS-187
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.✖

|Summary of Clinical Use|
|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|
|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) . 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 . The inhibitory effect of bafetinib on these kinases may decrease cellular proliferation and induce apoptosis in tumor cells driven by their overexpression .|
