Abstract
Conjugate vaccines have been the most successful way to prevent and control deadly bacterial infections; however their production is complex and tedious. The manufacturing process of these large molecules consists of a biological production and extraction of polysaccharide antigen and protein carrier and its chemical conjugation. Herein a simplified manufacturing process is described where the conjugate vaccine is completely produced in bacterial cells. The polysaccharide antigen and the protein carrier are expressed recombinantly in E. coli cells and linked covalently by an enzymatic process. This novel biological production system leads to improved products and opens up the possibility to develop a wide variety of novel vaccines.
Keywords: Bacterial vaccines, bioconjugates, chemical conjugation, conjugate vaccines, glycosylation, production of glycoconjugates in E. coli.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
