    摘要: Disclosed are immunogenic conjugates and therapeutic compositions that include such immunogenic conjugates. Also disclosed are methods of treating and/or inhibiting an Shigella sonnei infection. The disclosed immunogenic conjugates have the general structure: Pr—Sr—O—N═C-Kdo-OS wherein Pr is a carrier protein, Sr is an optional spacer moiety, Kdo is an 3-deoxy-D-manno-octulosonic acid or a derivative thereof, and OS is an oligosaccharide or polysaccharide obtained from S. sonnei. In specific examples, the immunogenic conjugates include the core oligosaccharide obtained from S. sonnei having the structure: wherein R is between 1 and 10 disaccharide repeat units. In specific examples, the disaccharide repeat unit included in the immunogenic conjugate has the structure: α-L-AltNAcA-3-β-FucNAc4N-4-.

    摘要: Methods for making an immunogenic conjugate that includes a hapten or an antigen covalently linked to a carrier. The methods include reacting a first agent with a dihydrazide resulting in a hydrazine-modified first agent, wherein the first agent is a hapten, an antigen or a carrier; reacting a second agent with a benzaldehyde compound resulting in a benzaldehyde-modified second agent, wherein the second agent is a hapten, an antigen or a carrier, provided that the first agent or the second agent is a carrier; and reacting the hydrazine-modified first agent with the benzaldehyde-modified second agent resulting in an immunogenic conjugate comprising a hapten or an antigen covalently linked to a carrier via a hydrazone linkage.
