  • Method of preparing a taxol derivative
    Patent number: 6911549
    Abstract: This invention provides 7-deoxy-taxol analogs of Formula I: The compounds of Formula I (including II and III) are useful for the same cancers for which taxol has been shown active, including human ovarian cancer, breast cancer, and malignant melanoma as well as lung cancer, gastric cancer, colon cancer, head and neck cancer, and leukemia.
    Type: Grant
    Filed: December 13, 1993
    Date of Patent: June 28, 2005
    Inventors: Jackson B. Hester, Jr., Roy A. Johnson, Robert C. Kelly, Eldon G. Nidy, Harvey I. Skulnick

  • 1-(Substituted-hydrocarbyl)-di- and trihalopyrazoles
    Patent number: 4089672
    Abstract: Certain new 1-(substituted-hydrocarbyl)-di- and trihalopyrazoles have been synthesized. They possess herbicidal and plant growth regulatory activity. The hydrocarbyl group, i.e., alkylene or alkenylene group at the 1-nitrogen of the pyrazole nucleus has either a carboxyl group, an hydroxymethyl group, an hydroxymethyl lower-alkanoate group a carboxylic lower-alkyl ester group a cyano group or a carboxylic amide group. The new compounds are prepared and isolated by conventional chemical reactions and procedures. An improved reaction for making the new carboxylic acids is described. Weed control methods and compositions for herbicidal use are also described.
    Type: Grant
    Filed: January 23, 1976
    Date of Patent: May 16, 1978
    Assignee: The Upjohn Company
    Inventors: Gabriel Kornis, Eldon G. Nidy, Henry J. Vostral, Arnolds Steinhards, deceased
