Abstract
Streptococcus pneumoniae is the leading source of life-endangering diseases like pneumonia, septicemia, and meningitis, as well as a major cause of death in children under 5 years old in developing countries. At least 98 serotypes of S. pneumoniae can be distinguished based on their structurally distinct capsular polysaccharides (CPS). Currently available CPS-based pneumococcal vaccines contain serotypes most frequently associated with invasive pneumococcal diseases. The polysaccharides used in commercial conjugate-vaccines are isolated from bacteria cultures comprising many laborious and operationally challenging steps followed by depolymerization of long polysaccharides into small fragments and their conjugation to the carrier protein. The medicinal chemistry approach for glycoconjugate vaccine development offers an exciting alternative to CPS isolation for a broad range of different glycan antigens. Glycan arrays containing well-defined synthetic glycans of CPS fragments and repeating units are used as a platform for the high-throughput screening of various serum samples and identification of protective glycotopes for vaccine candidates.
