with the anilinoquinazoline epidermal growth factor receptor (EGFR) irreversibleinhibitor [(11)C]-ML03 demonstrated a rapid metabolism of the tracer, which led to its low in vivo accumulation in EGFR overexpressing tumors. To enhance tumor uptake, the chemical structure of the compound was modified, and four new groups of EGFRinhibitors with a wide range of chemical reactivities were synthesized.
labeled inhibitor [(11)C]-ML03 suggested that more chemically stable inhibitors, labeled with a longer-lived radioisotope, could be better candidates for molecular imaging of epidermal growth factor receptor (EGFR) positive tumors. On the basis of this hypothesis we synthesized three new irreversible tyrosine kinase (TK) inhibitors with various chemical reactivities. The three new inhibitors were successfully
