Patents by Inventor Michael F. Summers

Michael F. Summers 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: 8318419
    Abstract: The present invention provides for testing methods to determine an effective testing agent that affects the activity of the HIV Gag protein at the plasma membrane of a cell, and specifically, effecting changes in the structural conformation of at least one fatty acid of PI(4,5)P2, a member of a family of differentially phosphorylated phosphatidylinositides, wherein inhibition of the extension of such fatty acid into the MA domain of the Gag protein reduces binding of Gag to the plasma membrane, thereby inhibiting virus particle assembly and subsequent replication of the HIV virus.
    Type: Grant
    Filed: July 18, 2008
    Date of Patent: November 27, 2012
    Assignee: University of Maryland, Baltimore County
    Inventors: Michael F. Summers, Jamil S. Saad

  • Patent number: 7361459
    Abstract: Methods for evaluating the antiviral activity of test compounds are provided. Further aspects of the methods involve the retroviral capsid protein of HIV-1. In another aspect, methods of reducing mortality associated with AIDS with a compound that binds to the apical cleft near the C-terminal end of the N-terminal domain of the HIV-1 capsid protein are provided. Derivatives of CAP-1, CAP-2, CAP-3, CAP-4, CAP-5, CAP-6 and CAP-7 are described that bind to the apical cleft of the N-terminal domain of the HIV-1 capsid protein and inhibit proper assembly of the core particle.

  • Patent number: 7183300
    Abstract: Substituted aryl aminomethyl thiazole ureas and analogues thereof that act as inhibitors of viral capsid formation, including HIV capsid formation, are provided here. Generally the virus capsid formation inhibitors described herein are compounds of Formula I wherein the variables A, R1, R2, R3, R4, X, Y, Z, A5, A6, A7, R8, R9, R12, and R13 are defined herein. Pharmaceutical compositions comprising such compounds and methods of treating animals infected with a virus having a capsid protein are provided herein. Methods of using such compounds to treat human patients infected with an HIV virus and reducing the mortality of AIDS are also provided herein.
