    Assignee: Glyconix Corporation
    Inventor: Brian Keith Shull
  • Patent number: 6720307
    Abstract: Novel analogs of fusidic acid are described with one or more carbohydrate units attached. Certain glycosylated analogs of fusidic acid have enhanced solubility properties in diluents or excipient of choice as compared to unmodified fusidic acid. Certain glycosylated analogs may be employed as chemotherapeutic agents and particular analogs may be useful for fighting anti-microbial infections.

  • Patent number: 5932709
    Abstract: The present invention relates to chemotherapeutic agents, and more particularly, to novel analogs of camptothecin. The camptothecin analogs display increased solubility through the hydrophilicity of added non-ionic sugar substituents. In accordance with the present invention, a member from the class of novel camptothecin analogs is to be delivered in vivo as a chemotherapeutic agent to fight cancer growth in the body.
