  • RADIOLABELED SUGARS FOR IMAGING OF FUNGAL INFECTIONS
    Publication number: 20220273829
    Abstract: Disclosed herein are compounds having a structure according to Formula I and optionally Formula IV. The compounds may be radiolabeled compounds useful for diagnosis and/or imaging fungal infections. In such embodiments, at least one substituent is a radionuclide, such as 18F. Also disclosed are precursor compounds according to Formula I and/or IV that are useful for making the radiolabeled compounds. In such embodiments, the precursor compound comprises at least one leaving group suitable for introducing a radionuclide, such as 18F, at a desired position. Also disclosed are methods for making and using the compounds, including embodiments of a method for imaging and/or diagnosing a fungal infection in a subject.
