    Abstract: A synthetic charged glycolipid is described comprising a sulfated saccharide group covalently linked to the tree sn-1 hydroxyl group of the glycerol backbone of an archaeal core lipid via a beta linkage. The synthetic charged glycolipids include compounds of formula I wherein n is 0 or 1; R is hydrogen or hydroxyl; and Y is hydrogen or a sulfate group, at least one Y being a sulfate group; and including pharmaceutically acceptable salts thereof. The sulfated glycolipid produces stable archaeosomes at a mol % ratio of from 100:0 to 30:70 (sulfated glycolipid: uncharged glycolipid) and which induce a protective immune response, including CD8+ and CD4+ T cell responses. Archaeosomes comprising the sulfated glycolipids described have desirable adjuvant properties, particularly when mixed with uncharged glycolipid at a mol % ratio of about 50:50.

    Abstract: The present invention relates to synthesis of novel higher oligomers and process of preparing the same. In particular the present invention relates to the chemical synthesis of oligomers of Neisseria meningitidis serogroup X (‘hereinafter Men-X), more particularly tetramer. The present invention provides Men-X capsular oligomers obtained from synthetic pathway using purified saccharides of specific chain length and provides said novel oligomers as candidates for the development of conjugate vaccine against bacterial meningitis caused due to Men-X infections.
