The present invention relates to the technical field of
molecular imaging probes, and particularly relates to a
molecular imaging probe labeling precursor targeting the DDR1
receptor, a probe thereof, and a preparation method and application thereof. The
molecular imaging probe labeling precursor targeting the DDR1
receptor provided by the present invention reacts with a
radionuclide to generate a molecular imaging probe targeting the DDR1
receptor, which has a strong receptor
binding force with the DDR1 receptor, can accurately locate the DDR1 receptor
in vivo, has excellent
in vivo targeting performance, and realizes the purpose of tumor molecular imaging through
nuclear medicine imaging. Compared with the
radioactive tracer [68Ga]Ga-SDUHYX01, the molecular imaging probe [68Ga]Ga-SDUHYX04 optimizes the molecular structure, reduces the
lipophilicity, adjusts the
metabolic pathway of the molecular imaging probe, thereby making the tumor-to-liver ratio of the molecular imaging probe higher, and also showing excellent imaging effects at 60 minutes.
