Abstract:
:Tyrosine kinases often play pivotal roles in the pathogenesis of cancer and are good candidates for therapeutic intervention and targeted molecular imaging. The precursor synthesis, radiosynthesis, and biological characterization of a fluorine-18 analog of dasatinib, a multitargeted kinase inhibitor, are reported. Compound 5 potently inhibits Abl, Src, and Kit kinases and inhibits K562 and M07e/p210bcr-abl human leukemic cell growth. Using positron emission tomography, we visualized K562 tumor xenografts in mice with [18F]-5.
