权利人:UNIV MANITOBA
摘要:The present invention generally relates to tetrahydropyranyl-derivatized amino acids, their syntheses and their incorporation into peptides and peptidomimetics. The tetrahydropyran moiety constrains the side chain of an amino acid, thereby providing a molecule that may act as a sugar- or amino acid-mimetic as well as a scaffold for combinatorial synthesis.

标题:Process for the preparation of protected mono-sugar and oligo-sugar halides
发明人：ERNST BEAT
权利人:CIBA GEIGY CORP
摘要:The reaction of protected monosaccharides or oligosaccharides or protected monosaccharide and oligosaccharide derivatives containing an anomeric hydroxyl group with secondary α-haloenamines affords high yields of protected glycosyl halides, which are valuable intermediates for the introduction of sugar groups in the synthesis of oligosaccharides, glycolipids or glycopeptides.

标题:Catalytic polymerization and depolymerization of 1,6-anhydrosugars
发明人：NIU JIA; WU LIANQIAN
权利人:THE TRUSTEES OF BOSTON COLLEGE
摘要:Methods for controlled synthesis and chemical recycling of stereoregular polysaccharides via polymerization of biomass-derived anhydrosugars are provided. The anhydrosugars react with an initiator in the presence of a synergy of a catalyst and the initiator providing the polysaccharides with high chain end fidelity and an excellent molecular weight distribution in a controlled manner, which allows for the preparation of polymeric systems with well-defined architectures. The polysaccharides obtained by such methods can be substantially converted to the start monomers in the present of a catalyst and can be used for biomedicine.

标题:Colchicine neoglycosides and methods for their synthesis and use

摘要:Colchicine neoglycosides, method for their synthesis and methods for their use are disclosed. The invention provides analogs of colchicine glycosylated to include a sugar moiety on a colchicine scaffold that is generally unglycosylated in nature. The colchicine neoglycosides disclosed herein are shown to have cytotoxic effects equivalent to at least the known cytotoxins paclitaxel and doxorubicin. Further, the neoglycosides disclosed according to the invention have physiologic effects not previously recognized in the alkaloid family that includes colchicine but recognized in other cytotoxic drug families such as the taxanes which act by stabilizing tubulin formation.
