Quillaja Saponin Variants with Central Glycosidic Linkage Modifications Exhibit Distinct Conformations and Adjuvant Activities.
Immunological adjuvants such as the saponin natural product QS-21 help stimulate the immune response to co-administered antigens and have become increasingly important in the development of prophylactic and therapeutic vaccines. However, clinical use of QS21 is encumbered by chemical instability, dose-limiting toxicity, and low-yielding purification from the natural source. Previous studies of ...
متن کاملAlginate Microsphere as a Delivery System and Adjuvant for Autoclaved Leishmania major and Quillaja Saponin: Preparation and Characterization
The goal of this study was to prepare and characterize alginate microspheres as an antigen delivery system and adjuvant for immunization against leishmaniasis. Microspheres encapsulated with autoclaved Leishmania major (ALM) and Quillaja saponin (QS) were prepared by an emulsification technique and characterized for size, encapsulation efficiency and release profile of encapsulate...
متن کاملPreparation and characterization of PLGA nanospheres loaded with inactivated influenza virus, CpG-ODN and Quillaja saponin
Objective(s): The purpose of this study was preparation and evaluation of PLGA nanospheres containing the influenza virus and different adjuvants, Quillaja saponin (QS) and CpG-ODN. Materials and Methods: Nanospheres were prepared using the double emulsion-solvent evaporation method. The morphological and physicochemical properties were studied by scanning electron microscopy...
متن کاملVersatile strategy for the divergent synthesis of linear oligosaccharide domain variants of Quillaja saponin vaccine adjuvants.
We describe a new, versatile synthetic approach to Quillaja saponin variants based on the natural product immunoadjuvant QS-21. This modular, divergent strategy provides efficient access to linear oligosaccharide domain variants with modified sugars and regiochemistries. This new synthetic approach opens the door to the rapid generation of diverse analogues to identify novel saponin adjuvants w...
متن کاملEvaluation of the anti-inflammatory activities of Quillaja saponaria Mol. saponin extract in mice
OBJECTIVE Quillaja saponaria bark contains a high percentage of triterpene saponins and has been used for centuries as antiinflammatory and analgesic agent in Chilean folk medicine. In the Present study the anti-inflammatory activities of the aqueous extract of commercially partially purified saponin from Quillaja saponaria Mol. in in vivo animal models. METHODS & MATERIALS Aqueous extract of...
