  • TRITERPENE SAPONINS, METHODS OF SYNTHESIS AND USES THEREOF
    Publication number: 20230131867
    Abstract: The present invention relates to triterpene glycoside saponin-derived adjuvants, syntheses thereof, intermediates thereto, and uses thereof. QS-7 is a potent immuno-adjuvant that is significantly less toxic than QS-21, a related saponin that is currently the favored adjuvant in anticancer and antiviral vaccines. Tedious isolation and purification protocols have hindered the clinical development of QS-7. A novel semi-synthetic method is provided wherein a hydrolyzed prosapogenin mixture is used to synthesize QS-7, QS-21, and related analogs, greatly facilitating access to QS-7 and QS-21 analogs for preclinical and clinical evaluation.
    Type: Application
    Filed: September 19, 2022
    Publication date: April 27, 2023
    Inventors: David GIN, Michelle ADAMS, Kai DENG, Philip LIVINGSTON, Govindaswami RAGUPATHI, Eric CHEA, Alberto FERNANDEZ-TEJADA, Lars Ulrik NORDSTROEM, William WALKOWICZ, Jeffrey GARDNER, Derek TAN
