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.

PSMA-targeted radiopharmaceutical for diagnosing and treating prostate cancer

The present invention relates to a process for producing an organofluoro compound including [F]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 ofF-labeled radiopharmaceuticals.

The present invention relates to a method for synthesizing a radiopharmaceutical using a cartridge, which makes it possible to carry out several steps of reaction required for synthesizing a radiopharmaceutical in the cartridge filled with a polymer. A method for synthesizing a radiopharmaceutical according to the present invention enables each step's reaction to be carried out with the solution confined in the cartridge so as not to flow out, thus being simplified compared to the conventional methods for synthesizing radiopharmaceuticals, and expediting the synthesis thereof.

This invention relates to novel precursors suitable forF radiolabeling of glutamate derivatives, methods for preparing such compounds and its intermediates, compositions comprising such compounds, kits comprising such compounds or compositions and methods forF radiolabeling of glutamate derivatives wherein the obtainedF radiolabeled glutamate derivatives are suitable for diagnostic imaging by Positron Emission Tomography (PET) of proliferative diseases e.g. tumor in mammals.

2-arylbenzothiophene derivatives or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition for the diagnosis or treatment of degenerative brain disease containing the same as an active ingredient. Since the 2-arylbenzothiophene derivatives of Formula 1 have a relatively high binding affinity for &#x3b2;-amyloid, they can be used as diagnostic reagents for diagnosing Alzheimer's disease at an early stage by non-invasive techniques when they are labeled with radioisotopes: wherein R-R, V, W, X, Y and Z are as defined in the Detailed Descript of the specification. Further, when the pharmaceutical composition containing the 2-arylbenzothiophene derivative binds with a low-molecular weight &#x3b2;-amyloid peptide binding compound, generation of malignant high-molecular weight &#x3b2;-amyloid deposits is minimized. Accordingly, the pharmaceutical composition can be used as a therapeutic agent of degenerative brain disease such as Alzheimer's disease.

The present invention relates to a method for preparation of organofluoro compounds containing radioactive isotope fluorine-18. More particularly, the present invention relates to a method for preparation of primary or secondary organofluoro compound by reacting fluorine salt containing radioactive isotope fluorine-18 with primary or secondary alkyl halide or primary or secondary alkyl sulfonate in the presence of alcohol of Chemical Formula 1 as a solvent to obtain high yield of organofluoro compound. Synthesis reaction according to the present invention may be carried out under mild condition to give high yield of the organofluoro compounds and the reaction time is decreased, and thereby is suitable for the mass production of the organofluoro compounds.
