Abstract: 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.

Abstract: Covalently lipidated oligonucleotides comprising the CpG dinucleotide unit, or an analogue thereof, may be used as immunostimulatory agents to protect against a disease caused by a cancer cell or a pathogen, either alone or in conjunction with immunogens and/or non-immunological agents. Lipidated oligonucleotides with special backbones, lipidated oligonucleotides with fewer than eight nucleotides, and lipidated oligonucleotides comprising a plurality of CpG dinucleotide-containing segments connected by a long internucleoside linkage are of particular interest. These compounds are also novel per se.

Abstract: New synthetic Lipid-A analogs based on monosaccharide (1) and disaccharide (2) derivatives were designed and prepared in the present invention. Both structures (1) and (2) incorporate novel lipid structures (3) and (4) that are not found in nature. Also, novel disaccharide Lipid-A structures (2) that incorporate novel contingents of uniform lipids and where R1, R4 and R5 are the same substitution group of structure (III) were synthesized. Liposome formulations containing totally synthetic components such as synthetic Lipid-A and synthetic lipopeptide derived from tumor-associated MUC1 mucin are described along with their therapeutic utility. Comparative test results of immunostimulating properties and toxicity of Lipid-A analogs (1) and (2) are included.

Abstract: A glycolipopeptide comprising at least one disease-associated epitope, and characterized by at least one lipidated interior amino acid or by the presence of a MUC1 epitope, may be used in a vaccine, preferably in conjunction with a liposome.
