The initial transfer of a complex glycan in protein N-glycosylation is catalyzed by oligosaccharyltransferase (OST), which is generally a multisubunit membrane protein complex in the endoplasmic reticulum but a single-subunit enzyme (ssOST) in some protists. To investigate the reaction mechanism of ssOST, we recombinantly expressed, purified and characterized the STT3A protein from Trypanosoma brucei (TbSTT3A). We analyzed the in vitro activity of TbSTT3A by synthesizing fluorescently labeled acceptor peptides as well as lipid-linked oligosaccharide (LLO) analogs containing a chitobiose moiety coupled to oligoprenyl carriers of distinct lengths (C10, C15, C20 and C25) and with different double bond stereochemistry. We found that in addition to proline, charged residues at the +1 position of the sequon inhibited glycan transfer. An acidic residue at the -2 position significantly increased catalytic turnover but was not essential, in contrast to the bacterial OST. While all synthetic LLO analogs were processed by TbSTT3A, the length of the polyprenyl tail, but not the stereochemistry of the double bonds, determined their apparent affinity. We also synthesized phosphonate analogs of the LLOs, which were found to be competitive inhibitors of the reaction, although with lower apparent affinity to TbSTT3A than the active pyrophosphate analogs.

In a document type is Article, introducing its new discovery.

Recent years have witnessed a growing interest in the development of new methods for linking sugars to peptides or proteins because natural glycopeptides or neoglycoconjugates with well defined chemical structures are very important tools to study diverse biological phenomena. Herein we report a novel, one-pot, three-component process for the synthesis of peptide-urea conjugates incorporating a hexafluorovaline or an aspartic acid alkyl ester residue under very mild conditions and high yields. The reaction has been exploited for the synthesis of a wide array of structurally diverse peptide-sugar conjugates through a regiospecific four-component, one-pot sequential domino process, by generating the reacting sugar-carbodiimides in situ from readily accessible starting materials.

To examine the versatility of the trans-bisglycoconjugation architecture for 5,10,15,20-tetrakis(pentafluorophenyl) porphyrin (TFPP) derivative-based photodynamic therapy (PDT), 25 porphyrin derivatives bearing D-glucopyranose moieties were prepared, and their in vitro photocytotoxicities were examined. trans-Bisglycoconjugated TFPP derivatives exerted the best photocytotoxicity among TFPP derivatives in the same category, regardless of the central metal ion and the type of glycoconjugation. trans-Bisglycoconjugated free-base TFPP bearing beta-D-glucopyranosylthio groups (trans- H22 SGlc) was found to be the most potent photosensitizer, not only in HeLa cells (EC50 < 5 nM), but also in highly metastatic cancer cell lines such as B16-BL6 melanoma cells (EC50 < 10 nM). UVvis and dynamic light-scattering measurements suggested that trans- bisglycoconjugated TFPP derivatives formed relatively large J-aggregates in an aqueous solution. trans-Bisglycoconjugated TFPP derivatives exhibited greater uptake by HeLa cells than those with different glycoconjugation patterns, with the exception of Zn(II) complexes. trans-Bisglycoconjugated TFPP derivatives efficiently generated hydrogen peroxide and hydroxyl radical by a type I photoreaction, while no significant differences were found in the efficiency of singlet oxygen generation by a type II photoreaction. These unique characteristics of transbisglycoconjugated TFPP derivatives support the conclusion that trans-bisglycoconjugation is a highly efficient and robust architecture for TFPP-based PDT development.

Various 2-pyridyl 1-thioglycosides, important synthetic intermediates and enzyme inhibitors in sugar chemistry, have been synthesized directly from the corresponding unprotected sugars in good yields by using 2-chloro-1,3- dimethylimidazolinium chloride (DMC) as dehydrative condensing agent. The reaction proceeds in aqueous media without using any protecting groups, affording 2-pyridyl 1-thioglycosides with beta-configuration selectively. According to the present method, not only unprotected monosaccharides but also unprotected oligosaccharides, such as cello-oligosaccharides, chito-oligo-saccharides, malto-oligosaccharides, and glucosamine oligomers, can be converted to the corresponding 2-pyridylthio derivatives, which would greatly expand the utility of aryl 1-thioglycosides in sugar chemistry.
