  • Synthesis and biological activity of bicyclic ABA analogs
    Patent number: 8969249
    Abstract: Bicyclic abscisic acid (ABA) analogs of Formula (I) and (II) and the process for their production are disclosed. The bicyclic ABA analogs include the structural elements and functional groups of the parent molecule that are required for activity, and have an aromatic ring fused to the ring replacing the vinyl methyl group of absicisie acid. Methods for using the bicyclic ABA analogs to inhibit cell growth and seed germination are also disclosed.
    Type: Grant
    Filed: May 10, 2005
    Date of Patent: March 3, 2015
    Assignee: National Research Council of Canada
