We report on the efficient synthesis of linear trehalose diesters (TDEs) and iso-branched TDEs (maradolipids or iso-TDEs) and their ability to activate bone marrow-derived macrophages (BMDMs) as determined by cytokine (IL-1β IL-12, IL-6, IL-10) and chemokine (MIP-2) production. Both classes of TDEs were found to activate BMDMs in a Mincle-dependent manner, with longer-chain (≥C18) lipids leading to a robust inflammatory response. On the whole, the iso-branched TDEs led to greater cytokine production and a faster immune response when compared to their linear counterparts. Moreover, C12-TDE and iso-C12-TDE elicited the production of MIP-2 by BMDMs, thereby providing the first example of TDEs with a chain length of ≤ C12 leading to a Mincle-dependent immune response and one that is less inflammatory in nature.

Sulfobacin A (1), B (2), and flavocristamide A (3), new sulfonolipids isolated from Chryseobacterium sp. were synthesized stereoselectively by starting from L-cysteine.

An adjuvant formulation includes a monophosphoryl Lipid A (MPLA) analogue, a Pam3CSK4 analogue, or a muramyldipeptide (MDP) analogue, or combinations thereof. The adjuvant may be formulated in soluble form or in a nanoparticle, such as polylactic glycolic acid nanoparticles. A vaccine formulation comprises the adjuvant formulation and an immunogen. Methods of vaccinating an animal include delivering the vaccine formulation to the animal.
