Manivannan Ethirajan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Cyanine dye compound and preparation method therefor, and dual-function agent for photodynamic therapy and preparation method therefor
    Patent number: 9821062
    Abstract: Disclosed are a cyanine dye compound and a preparation method therefor, and a dual-function agent for photodynamic therapy and a preparation method therefor. The provided cyanine dye compound is connected to multiple markers, which improves the accuracy of combination of dye and tumor cells, effectively reduces the background value, and avoids excessive residues in the liver. The provided cyanine dye compound is conjugated with the photosensitizer at 2?? position, so that tumor highly absorbs the conjugates.
    Type: Grant
    Filed: February 6, 2013
    Date of Patent: November 21, 2017
    Assignee: ZHEJIANG HISUN PHARMACEUTICAL CO., LTD.
    Inventors: Ravindra K. Pandey, Nayan Patel, Manivannan Ethirajan, Hua Bai, Zhenliang Chen
