Patents by Inventor Duy Hua

Duy Hua 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).

  • Patent number: 9850520
    Abstract: An electrochemical method for measuring the activity of enzymes using nanoelectrode arrays fabricated with vertically aligned carbon nanofibers. Short peptide substrates specific to disease-related enzymes are covalently attached to the exposed nanofiber tips. A redox moiety, such as ferrocene, can be linked at the distal end of the nanofibers. Contact of the arrays with a biological sample containing one or more target enzymes results in cleavage of the peptides and changes the redox signal of the redox moiety indicating the presence of the target enzymes.
    Type: Grant
    Filed: June 30, 2014
    Date of Patent: December 26, 2017
    Assignee: Kansas State University Research Foundation
    Inventors: Jun Li, Duy Hua, Lateef Uddin Syed, Allan Prior, Luxi Swisher
  • Patent number: 9474759
    Abstract: Antiviral protease inhibitors, including peptidyl aldehydes, peptidyl ?-ketoamides, peptidyl bisulfate salts, and peptidyl heterocycles, are disclosed, along with related antiviral compounds, and methods of using the same to treat or prevent viral infection and disease. The compounds possess broad-spectrum activity against viruses that belong to the picornavirus-like supercluster, which include important human and animal pathogens including noroviruses, enteroviruses, poliovirus, foot-and-mouth disease virus, hepatitis A virus, human rhinovirus (cause of common cold), human coronavirus (another cause of common cold), transmissible gastroenteritis virus, murine hepatitis virus, feline infectious peritonitis virus, and severe acute respiratory syndrome coronavirus.

  • Publication number: 20080039528
    Abstract: Techniques for the chelation or ejection of Zn2+ from zinc finger peptides are disclosed, which can be useful in the treatment or control of viruses and viral diseases and malaria. The invention comprises contacting a zinc finger peptide with an effective amount of a bishydroxamic acid or salt thereof, either in vivo or in vitro.

  • Patent number: 6828450
    Abstract: This invention provides analogs of triptycene which are useful as anticancer drugs, as well as for other uses. The potency of these compounds is in a similar magnitude as daunomycin, a currently used anticancer drug. Each compound of the invention produces one or more desired effects (blocking nucleoside transport, inhibiting nucleic acid or protein syntheses, decreasing the proliferation and viability of cancer cells, inducing DNA fragmentation or retaining their effectiveness against multidrug-resistant tumor cells).
