  • Patent number: 10538486
    Abstract: The present invention relates to a hydroxamic acid-based contrast agent containing an isotope of fluorine, which comprises a compound having a structure of Formula (III): wherein R1 represents radioactive fluorine-18 (18F) or isotope fluorine-19 (19F), and R2 represents hydroxyamine —(NH)OH. The hydroxamic acid-based contrast agent containing an isotope of fluorine provided in the present invention has the capability of selectively inhibiting histone deacetylase (HDAC) subtypes 8/6/3, and specifically targets to the focus of spinocerebellar ataxia with over-activation of HDAC. By labeling with the radioisotope fluorine-18, a positron emission tomography (PET) image is obtained with the hydroxamic acid-based contrast agent containing radioisotope fluorine-18, whereby spinocerebellar ataxia is effectively detected.

  • Patent number: 10117956
    Abstract: The present invention is related to a radiolabeled active targeting pharmaceutical composition, including: a bioconjugate and a radionuclide, wherein the bioconjugate includes a biomolecule and a metal nanoparticle, wherein the biomolecule has an affinity for receptors on the surface of a cell membrane and is selected from the group consisting of a peptide and a protein. The present invention further provides a method for evaluating a thermal adjuvant therapy for tumors and a kit thereof. The above-mentioned pharmaceutical composition is applied to evaluate a tumor accumulation time, so as to establish the optimal policy for a radiofrequency- or laser-induced thermal adjuvant therapy for tumors.
