  • 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: 11057855
    Abstract: The present invention relates to a method of detecting an access address of a physical channel in a Bluetooth signal to which channel coding is applied, the method including: performing initial signal processing in a unit of a specific length in a preamble section of a Bluetooth signal; and performing channel decoding in the specific length for a preamble part remained after the initial signal processing, wherein the specific length is a bit pattern length of a bitstream which is repeated in the preamble section or a length of a bitstream input for channel decoding. According to the present invention, channel decoding is performed in a unit of a bit pattern length of an access address from the remaining preamble part, and thus detection of the access address is available even though a start point of the access address is not provided.
