The National Cancer Institute''s Laboratory of Cell Biology is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize bodipy conjugated tyrosine kinase inhibitors that are currently used in the clinic for the treatment of CML or gastric cancers. We are also interested in evaluating third generation tyrosine kinase inhibitor derivatives as modulators of ABC drug transporters to improve the efficiency of chemotherapy in animal (mouse) model system. In addition, we can identify possible pharmacokinetic interactions of the novel kinase inhibitors with ABC drug transporters.
Investigators at the National Institutes of Health have produced a fluorescently labeled derivative of the clinically-approved, tyrosine kinase inhibitor (TKI) nilotinib (Tasigna) for use in research. This was accomplished by conjugating the fluorescent dye BODIPY-FL to nilotinib.
The TKI imatinib (Gleevec) is the first targeted therapeutic developed and is used as first line treatment of Philadelphia chromosome-positive (Ph+) cancers like chronic myeloid leukemia (CML). Although imatinib is highly effective, after continued use the cancer cells frequently become resistant to the drug. Nilotinib is a second generation TKI developed to overcome imatinib resistance, but eventually it can also result in drug resistance.
The fluorescent nilotinib conjugate was developed to study the mechanism by which cancer cells become resistant to nilotinib and better understand its cytotoxic effects.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
