摘要： The present invention relates to the the cell-based production of bacterial nonulosonates and their biosynthetic precursors. Specifically, the present invention provides recombinant cells for the production of pseudaminic acid, legionaminic acid, UDP-2,4-diacetamido-2,4,6-trideoxy-□-L-altropyranose, and UDP-2,4-diacetamido-2,4,6-trideoxy-□-D-glucopyranose. Methods for producing the sugars are also provided.

摘要： 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.

摘要： N. gonorrhoeae has become resistant to almost every conventional antibiotic. Described herein is the use of CMP-nonulosonate analogues to counter gonococcal complement evasion. The nonulosonate sugar is incorporated into the lipooligosaccharide of the N. gonorrhoeae which in turn reduces the serum resistance of the bacteria. This provides a novel therapeutic strategy against the global threat of multi-drug resistant gonorrhea.
