  • Photocleavable cobalt-nitrosyl complex and nitric oxide carrier containing the same
    Patent number: 11351260
    Abstract: The present invention relates to a cobalt-nitrosyl complex having photocleavable ligands. The cobalt-nitrosyl complex provided in one aspect of the present invention is adept in the delivery of NO, with exquisite temporal control using light, without gene editing. In addition, the complex provided in one aspect of the present invention is excellent in biocompatibility because it is chemically stable, non-toxic at cell level, and non-perturbative in cellular environments.
    Type: Grant
    Filed: May 8, 2020
    Date of Patent: June 7, 2022
    Assignee: DAEGU GYEONGBUK INSTITUTE OF SCIENCE AND TECHNOLOGY
    Inventors: Jaeheung Cho, Daeha Seo, Jisu Choe

  • Method of converting a nitrile functional group into a hydroxamic functional group by using a peroxocobalt complex at room temperature and normal pressure
    Patent number: 10399928
    Abstract: The method of the present invention for converting a nitrile functional group into a hydroxamic acid functional group can be easily performed at room temperature and under normal pressure by using a peroxocobalt complex. The final hydroxamic acid functional group produced through the intermediate Hydroximatocobalt (III) compound or the derivative comprising the same has been known to be able to inhibit the growth of cancer cells, so that the conversion method of the present invention can be applied to the preparation of a pro-drug for anticancer treatment.
