Galectin-3 Precipitates as a Pentamer with Synthetic Multivalent Carbohydrates and Forms Heterogeneous Cross-linked Complexes
Nisar Ahmad,Hans J. Gabius,Sabine André,Herbert Kaltner,Subramanian Sabesan,René Roy,Bingcan Liu,Frank P. Macaluso,C. Fred Brewer +8 more
TL;DR: Galectin-3 is unique among the Galectin family of animal lectins in its biological activities and structure as mentioned in this paper, it possesses anti-apoptotic activity and its kinetics of precipitation are fast, on the order of seconds.
Journal ArticleDOI

TL;DR: The large-scale synthesis, pharmaceutical development, and clinical evaluation of a conjugate vaccine composed of a synthetic capsular polysaccharide antigen of Haemophilus influenzae type b (Hib) demonstrate that access to synthetic complex carbohydrate–based vaccines is feasible and provides a basis for further development of similar approaches for other human pathogens.
Book ChapterDOI
Design and creativity in synthesis of multivalent neoglycoconjugates.
Yoann M. Chabre,René Roy +1 more
TL;DR: This chapter briefly surveys the concept of multivalency involved in carbohydrate–protein interactions and discusses in regard to recent steps undertaken in glycobiology toward identification of lead candidates using microarrays and modern analytical tools.
Journal ArticleDOI
Syntheses and some applications of chemically defined multivalent glycoconjugates.
TL;DR: The synthesis of other neoglycoconjugates with various shapes, valencies, and conformations has reached considerable levels of sophistication and holds promise as a new tool for glycobiology and biomedical applications as mentioned in this paper.
Journal ArticleDOI
Inhibition of viral adhesion and infection by sialic-acid-conjugated dendritic polymers.
Jon D. Reuter,Andrzej Myc,Michael M. Hayes,Zhonghong Gan,René Roy,Dujie Qin,Rui Yin,Lars T. Piehler,Roseita Esfand,Donald A. Tomalia,James R. Baker +10 more
TL;DR: Significant (p < 0.001) dose-dependent reduction of influenza infection in mammalian cells by polymeric inhibitors is demonstrated, the first such demonstration for multivalent SA inhibitors.
