Abstract
Avian pathogenic Escherichia coli O1 (APEC O1) is a pathogenic bacterium that causes significant economic losses in the poultry industry and raises concerns about zoonotic infections. The development of effective vaccines against APEC O1 is essential due to antibiotic resistance and the potential for severe symptoms in both chickens and humans. In this context, we have been focusing on the O1A, O1B, and O1C antigen structures derived from E. coli O1 lipopolysaccharide (LPS). In this study, the first synthesis of the pentasaccharide repeating units of the O1B and O1C antigens was successfully achieved. The synthesis and immunological evaluation of their conjugates with bovine serum albumin (BSA) were conducted. Only the O1A-pentasaccharide structure is a glycotope candidate for APEC O1. Keyhole limpet hemocyanin (KLH)–O1A-pentasaccharide conjugate was also synthesized, and its immunogenicity was evaluated by the ELISA assay. The efficient production of antibodies capable of binding to both APEC O1 LPS and the O1A-pentasaccharide structure was observed, indicating that O1A-pentasaccharide is a promising vaccine candidate against APEC O1.
Regioselective and Stereospecific β‐Arabinofuranosylation by Boron‐Mediated Aglycon Delivery

　View Summary

Regio- and stereoselective formation of the 1,2-cis-furanosidic linkage has been in great demand for efficient synthesis of biologically active natural glycosides. In this study, we developed a regioselective and β-stereospecific d-/l-arabinofuranosylation promoted by a boronic acid catalyst under mild conditions. The glycosylations proceeded smoothly for a variety of diols, triols, and unprotected sugar acceptors to give the corresponding β-arabinofuranosides (β-Arbf) in high yields with complete β-stereoselectivity and high regioselectivity. The regioselectivity was completely reversed depending on the optical isomerism of the donor used and was predictable a priori using predictive models. Mechanistic studies based on DFT calculations revealed that the present glycosylation occurs through a highly dissociative concerted SNi mechanism. The usefulness of the glycosylation method was demonstrated by the chemical synthesis of trisaccharide structures of arabinogalactan fragments.

　View Summary

Highly stereoselective synthesis of 1,2-cis glycosides remains a challenging task due to the lack of reliable neighboring group participation (NGP) from the 2-O-acyl functionality in the glycosyl donor. In this context, our group recently developed highly 1,2-cis-stereoselective glycosylation methods, named boron-mediated aglycon delivery (BMAD), using organoboron reagents and 1,2-anhydroglycosyl donors. In this mini-review article, we introduce the BMAD methods and their applications to the synthesis of biologically active natural products and complex glycosides reported since our mini-review article published in this journal in 2017.

　View Summary

Several agents, that target-selectively photo-degrade certain disease-related proteins and oligosaccharides, were designed and synthesized. Furthermore, it was found the agents thus developed work not only in test tube but also in disease-related cells. From these studies, a new approach for the design of light-activated and molecular-targeted medicines has been established.
