Venkatesh Tekumalla 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: 9737551
    Abstract: The present invention is a method and compound for treating specific cancerous cell lines. The invention treats liver cancer by directing a cancer-fighting drug into the liver hepatoportal circuit. The cancer-fighting drug is attached to a naturally produced molecule which functions primarily in the hepatoportal circuit and has organotropism for the hepatoportal circuit.
    Type: Grant
    Filed: February 7, 2017
    Date of Patent: August 22, 2017
    Assignee: North American Biomedical Research Center USA, Inc.

  • Patent number: 7754694
    Abstract: The present invention provides pyrrolo[2,1-c][1,4]benzodiazepine-glycoside prodrug of general formula 1a-b, useful as selective anticancer agents. The present invention also provides a process for the preparation of pyrrolo[2,1-c][1,4]benzodiazepine-glycoside prodrugs of general formula 1a-b. This invention also provides activation of these prodrugs by E.coli ? galactosidase and envisaged that these molecules are toxic to human cancer cell lines in the presence of the enzyme E.coli ?-galactosidase. The prodrugs 1a and 1b were also found to be toxic to human cancer HepG2 cells even in the absence of the E.coli ?-galactosidase. The toxic effect of the molecules when activated was similar to that of the parent molecules 6a and 6b, respectively.
