  • Publication number: 20170319720
    Abstract: A method for preparing a radiopharmaceutical and, specifically, a method for preparing an organic fluoride-aliphatic compound usable as a radiopharmaceutical, a method for purifying the prepared organic fluoride-aliphatic compound, and a method for preparing a radiopharmaceutical by using a cassette comprising a backdraft preventing reaction container. A method for preparing an organic fluorinated aliphatic compound includes allowing a fluorine salt to react with a leaving group-containing aliphatic compound by using a multifunctional solvent represented by the following Chemical Formula 1 to obtain an aliphatic compound labeled with [18F] fluoride substituting for the leaving group. The organic fluoride-aliphatic compound can be prepared and purified through even a simple process at high yield, high efficiency, and high purity, and the radiopharmaceutical can be safely prepared without damage to a synthetic apparatus.

  • Patent number: 9133143
    Abstract: The present invention relates to (3-fluoro-2-hydroxy)propyl-functionalized aryl derivatives or to the pharmaceutically acceptable salt thereof, to a method for preparing same, and to a pharmaceutical composition containing same as active ingredients for the diagnosis or treatment of neurodegenerative brain diseases. The aryl derivatives of the present invention are (3-fluoro-2-hydroxy)propyl-functionalized to increase the polarity thereof, and therefore the drugs containing the aryl derivatives can easily permeate into the cerebrovascular membrane, thus increasing the effectiveness of the drugs. As the aryl derivatives of the present invention strongly bind to ?-amyloid, the aryl derivatives, when labeled with radioisotope, can be used as a diagnostic agent for non-invasively diagnosing early Alzheimer's disease.

  • Publication number: 20150045548
    Abstract: The present invention relates to a method for labelling fluorine-18, which is a radioisotope, and more specifically, to a method for labelling a [18F]fluoride in a method for preparing an organic [18F]fluoro compound by reacting an alkyl halide or an alkyl sulfonate with a [18F]fluoride, wherein a [18F]fluoride supported on a quaternary alkyl ammonium polymer support is eluted using a solution containing a metal salt or a quaternary ammonium salt with an adjusted pH, and a base is not additionally used. The present invention enables a labeling reaction without an additional base after precisely reflecting the concentration of a base absolutely necessary for the nucleophilic substitution of a [18F]fluoride or eluting a [18F]fluoride using a [18F]fluoride eluent with an adjusted pH, thereby stably obtaining a [18F]fluoride-labelled compound in a high yield, and is thus useful for production of fluorine-18-labelled radioactive medical supplies.

  • Patent number: 8497260
    Abstract: 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 ?-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 R1-R4, 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 ?-amyloid peptide binding compound, generation of malignant high-molecular weight ?-amyloid deposits is minimized. Accordingly, the pharmaceutical composition can be used as a therapeutic agent of degenerative brain disease such as Alzheimer's disease.
