  • Patent number: 9676818
    Abstract: The present disclosure is directed to a novel class of toll-like receptor 2-agonistic (TLR2) lipopeptide compounds having specific structures, and synthetic methods of making the compounds. These compounds provide high potency of agonistic activities with human, other than murine, TLR2, and are useful as vaccine adjuvants. Vaccines are perhaps one of the most successful medical interventions against infectious disease.
