Patents by Inventor Isaac C. Chan-Kai

Isaac C. Chan-Kai 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).

  • Polyketides and antibiotics
    Patent number: 7022825
    Abstract: Facile methods for preparing diketide and triketide thioesters are disclosed. The resulting thioesters may be used as intermediates in the synthesis of desired polyketides, and may contain functional groups which ultimately reside in side chains on the resulting polyketide and thus can be used further to manipulate the polyketide so as form derivatives. The polyketides produced may also be tailored by glycosylation, hydroxylation and the like. New polyketides and their derivatives and tailored forms are thereby produced.
    Type: Grant
    Filed: August 8, 2002
    Date of Patent: April 4, 2006
    Assignee: Kosan Biosciences, Inc.
    Inventors: Gary Ashley, Isaac C. Chan-Kai, Mark A. Burlingame
