    glycosyl fluorides using sulfur(VI) hexafluoride as an inexpensive and safe fluorinating agent and 4,4′-dimethoxybenzophenone as a readily available organic photocatalyst. This mild method was employed to generate 16 different glycosyl fluorides, including the substrates with acid and base labile functionalities, in yields of 43%–97%, and it was applied in continuous flow to accomplish fluorination on an

  • Synthesis of an Isostere of an O-Linked Glycopeptide

    日期:2004.9.1
    route for the synthesis of an electrophilic, carbocyclic galactose equivalent from D-galactose is described. The strategy utilizes ring-closing metathesis with Grubbs's second-generation catalyst as the key step. The galactose-derived electrophile reacted in an S(N)2 fashion with N-Boc-cysteine methyl ester to provide an alpha-galactosylserine isostere. The method was extended to the synthesis of a glycopeptide

    orientation of the anomeric glycosidic bond of CCL-34 resulted in a complete loss of activity (β-CCL34). Surprisingly, a change in configuration of the anomeric glycosidic bond in a glucosyl glycolipid is tolerable (CCL-34-S14). Another noteworthy observation is that the activity of a L-fucosyl derived glycolipid (CCL-34-S13) was comparable to that of CCL-34. In sum, this study determines the structural
    通过改变α-GalCer衍生的前导化合物(CCL-34)的脂链长度和糖结构,合理设计了一系列新的不含磷酸基的单糖基糖脂,带有两个脂链),这是一种有效的TLR4激动剂。在稳定表达人TLR4,MD2和CD14(293-hTLR4 / MD2-CD14)的HEK293细胞系中测量了包含60个成员的具有不同脂质链长度的化合物的基于半乳糖基丝氨酸的合成文库的NF-κB活性。结果表明,脂胺和脂肪酸激活TLR4的最佳碳链长度分别为10-11和12。对包含具有各种糖基部分和固定脂链长度的化合物的20元合成基于糖基丝氨酸的脂质文库的评估表明,CCL-34中的半乳糖部分可以被取代葡萄糖而不会丧失活性(CCL-34-S3和CCL-34-S16)。改变CCL-34的异头糖苷键的方向导致活性完全丧失(β-CCL34)。令人惊讶地,糖基糖脂中的异头糖苷键的构型变化是可忍受的(CCL-34-S14)。另一个值得注意的发
  • The Palladium-Catalyzed Glycosylation of Halotropones

    日期:2023.1.20
    A range of mono- and disaccharides, including glucose derivative 10, has been cleanly coupled, in the presence of a Pd catalyst, with various halogenated and structurally distinctive tropones, including “parent” compound 11, to afford the corresponding α- and β-anomeric forms of the tropolone glycosides, e.g., 12 and 13, respectively. Varying the ligand used influences the anomer distribution significantly

  • Synthesis and Assessment of Globotriose–Chitosan Conjugate, a Novel Inhibitor of Shiga Toxins Produced by <i>Escherichia coli</i>
    作者:Xuebing Li、Peixing Wu、Shuihong Cheng、Xun Lv
    DOI:10.1021/jm201570s
    日期:2012.3.22
    Shiga toxin (Stx)-producing Escherichia coli (STEC) causes diarrhea and colitis in humans that can develop into a life-threatening hemolytic uremic syndrome (HUS). Developing efficient means of controlling STEC diseases, for which no drugs or vaccines are currently available, remains a high priority. We report here the construction and development of chitosan conjugates bearing the Stx ligand trisaccharide globotriose to demonstrate their potential as STEC disease treatment agents. The synthesis was accomplished by grafting a globotriose derivative containing an aldehyde-functionalized aglycone to chitosan amino groups. The obtained globotriose-chitosan conjugate bound with high affinity to Stx and efficiently neutralized its toxicity on Vero cells. Moreover, Six levels in the gut of infected mice receiving oral doses of the conjugate were greatly diminished, enabling the mice to resist a fatal STEC challenge. The conjugate appears to function as a Stx adsorbent in the gut, preventing toxin entry into the bloodstream and consequent development of HUS. As such, the conjugate could act as a novel agent against STEC disease.
