Abstract
A number of MS- and natural-saponin-based vaccine adjuvant candidates have been prepared. The MS derivatives were prepared by incorporating a terminal-functionalized side chain into the C3 glucuronic acid unit of the natural saponins MS I and II through amide formation reaction; and the QS analogs were prepared via multi-step organic synthesis. These unnatural saponins showed significantly different immunostimulant activity profiles, suggesting that the structure of side chain, triterpenoid core, and oligosaccharide domain together orchestrate each saponin's characteristic potentiation of immune responses.
