  • Patent number: 11931431
    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.

  • Patent number: 11306091
    Abstract: The present invention relates to a process for producing an organofluoro compound including [18F]fluorine, and by using a solvent represented by Formula 1 in nucleophilic fluorination reaction, an organofluoro compound may be prepared at a high yield. In addition, since the solvent has very excellent solubility for a precursor compound, the solvent is suitable for the automated synthesis of 18F-labeled radiopharmaceuticals.

  • Publication number: 20190202820
    Abstract: The present invention relates to a process for producing an organic fluoro compound containing [18F]fluorine. The method of the present invention for producing the organic fluoro compound is not only advantageous for producing the organic fluoro compound with high yield by using the solvent represented by formula 1 for nucleophilic fluorination reaction but also suitable for automatic synthesis of 18F-labeled radiopharmaceuticals due to the excellent solubility of the precursor compound in the solvent.

  • Patent number: 8943612
    Abstract: A sanitary finger cap including: an insertion portion having a generally cylindrical shape and adapted to be fitted to a third knuckle of a finger connected to the center of a hand or to a portion of a second knuckle of the finger; and a grasping portion connected with one side of the insertion portion as a unitary body, in a shape of a general corn or pyramid in such a manner as to become small in thickness as it goes toward the other side thereof, and adapted to be fitted to a first knuckle as the end portion of the finger or to the second knuckle of the finger so as to grasp food thereon.
