VA06
VA06 is a derivative of QS-21 (HY-101092A) that retains potent adjuvant activity while significantly reducing toxicity. VA06 self-assembles into flexible worm-like micelles with continuously elongated nanostructures and enhanced drug-loading encapsulation capacity. VA06 induces antigen-specific antibody production, enhances the secretion of TNF-α, IFN-γ and IL-2 in CD4+ and CD8+ T cells, and promotes the expression of immune-related and antiviral-related genes in mature dendritic cells. VA06 does not require liposome formulation, which simplifies production and storage processes. VA06 can be used in the research of varicella-zoster virus infection and Mycobacterium tuberculosis infection.

Biological Activity
VA06 (0.5 mM; 1 min) in PBS solvent self-assembles into flexible wormlike micelles with continuous, elongated nanostructures[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
The VA06+MPL (BST02) formulation (5 μg VA06 + 5 μg MPL per dose; subcutaneous injection; administered on day 0 and day 14) induces robust VZV-gE-specific humoral and cellular immune responses in female C57BL/6J mice[1].
VA06 (5 μg per mouse; intramuscular injection; single administration) exhibits excellent in vivo muscle tolerance in male rats, with no reactogenicity detected[1].
