  • Device and process for nucleophilic fluorination
    Patent number: 7482498
    Abstract: The invention relates to a device and a process for nucleophilic fluorination of a substance, especially for synthesis of an 18F-labeled substance for examination using a positron emission tomograph. The device comprises an anion exchange device (102) for extraction of [18F]fluoride ions by means of adsorption from a target fluid, whereby the anion exchange device (102) can be charged via a supply device (101) with the target fluid; and a measurement device (104) with a measurement chamber (103) for measuring initial radioactivity of the [18F]fluoride ions, the anion exchange device (102) being arranged at least partially in the measurement chamber (103) of the measurement device (104).

  • Radiopharmaceuticals for diagnosing Alzheimer's disease
    Patent number: 6872381
    Abstract: This invention is directed to the use of radiopharmaceuticals in diagnosing Alzheimer's disease. In particular the radiopharmaceuticals of the invention are able to pass through the blood-brain barrier and bind to the CCR1 receptor present in brain tissue of patients having Alzheimer's disease.

  • Radiopharmaceuticals for diagnosing Alzheimer's disease
    Patent number: 6676926
    Abstract: The compounds of formulas (I) and (II) are radiopharmaceuticals that bind to the CCR1 receptor and are able to pass through the blood-brain barrier, and are therefore useful in diagnosing Alzheimer's disease, preferably at an early stage of the disease, wherein X1, X2, R1, R2, R3, R4 and R5 are as defined herein.
