Definition

A radioconjugate composed of a derivative of the multi-targeted kinase inhibitor dasatinib conjugated to the radioisotope fluorine F 18, with potential imaging activity during positron emission tomography (PET). Upon administration of fluorine F 18 dasatinib, dasatinib targets and binds to Bcr/Abl, SRC-family protein-tyrosine kinases, c-Kit and platelet-derived growth factor receptor (PDGFR). Upon binding, the fluorine F 18 moiety allows PET imaging of tumor cells and can be used as a tracer for the biodistribution of dasatinib.
