  • Patent number: 6768007
    Abstract: 3′,4′-di-O-camphanoyl-(+)-cis-khellactone analogs according to the present invention have been found to have anti-HIV activity. The compounds of the present invention have the following formula: or a pharmaceutically acceptable salt, ester or prodrug thereof, wherein R1, R2, R3, R4, X, and Z are set in the specification. The invention is also directed to pharmaceuticals compositions comprising one or more compounds of Formula I, optionally further comprising one or more anti-viral agents or immunostimulating agents. Further, the invention is directed to the use of compounds of Formula I for the inhibition of a retroviral infection in cells or tissue of an animal, for the treatment of a patient suffering from a retroviral-related pathology, for the prevention of transmission of HIV infection from an HIV infected pregnant woman to a fetus, and for the prevention of transmission of HIV infection during sexual intercourse.

  • Publication number: 20030104473
    Abstract: The present invention provides common ligand mimics that act as common ligands for a receptor family. The present invention also provides bi-ligands containing these common ligand mimics. Bi-ligands of the invention provide enhanced affinity and/or selectivity of ligand binding to a receptor or receptor family through the synergistic action of the common ligand mimic and specificity ligand that compose the bi-ligand. The present invention also provides combinatorial libraries containing the common ligand mimics and bi-ligands of the invention. Further, the present invention provides methods for manufacturing the common ligand mimics and bi-ligands of the invention and methods for assaying the combinatorial libraries of the invention.
