Abstract: The present invention relates to a pharmaceutical composition for diagnosing and treating prostate cancer, capable of targeting PSMA, and a compound provided by one aspect of the present invention has a glutamine-urea-lysine compound to which a radioactive metal-coupled chelator is structurally coupled and to which an aryl group that can additionally bind to PSMA protein is coupled. Coupling between the glutamine-urea-lysine compound and the chelator includes a polar spacer so as to serve the role of reducing in vivo nonspecific coupling and exhibit an effect of being rapidly removed from vital organs, but not from prostate cancer. These characteristics lower the radiation exposure, which is caused by a therapeutic radioisotope-coupled compound, to normal tissue and organs, and thus reduce side effects. In addition, a compound that contains a phenyl group having a coupling force with albumin has an increased residence time in the blood, thereby becoming more accumulated in prostate cancer.
