Patents by Inventor Erin T. Pelkey

Erin T. Pelkey 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).

  • Guanidinium transport reagents and conjugates
    Patent number: 7169814
    Abstract: Transport reagents and conjugates of therapeutic agents linked to transport reagents are described. In particular, the transport reagents have a plurality of guanidinium moieties that are either contiguous or spaced along a backbone, but are sufficiently removed from the backbone via tethers, to allow their interaction with a cell or tissue surface, leading to uptake of the therapeutic agent.
    Type: Grant
    Filed: December 11, 2002
    Date of Patent: January 30, 2007
    Assignees: The Board of Trustees of the Leland Stanford Junior University, Cellgate, Inc.
    Inventors: Jonathan B. Rothbard, Paul A. Wender, Kanaka Pattabiraman, Erin T. Pelkey, Theodore C. Jessop
  • Bi-directional synthesis of oligoguanidine transport agents
    Patent number: 7067698
    Abstract: Synthesis routes that can be adapted to large scale synthesis of oligoguanidine compounds such as oligoarginine compounds are described which use a perguanidinylation step to convert a group of ?-amino groups to the corresponding guanidinyl groups. These compounds find utility as transport agents. Modified oligoguanidine compounds are also described.
    Type: Grant
    Filed: August 2, 2002
