    脑膜炎奈瑟菌A型荚膜多糖二聚亚基膦类似物的合成
    摘要:
    连接其荚膜多糖的 N-乙酰甘露糖胺重复单元的磷酸二酯桥的化学不稳定性极大地阻碍了针对 A 型脑膜炎奈瑟菌的糖缀合物疫苗的开发。我们描述了膦二糖 α-D-Man-pNAc-[1 →CH 2 -P(O)(O - )→6]-β-D-ManpNAc-(I →O) (CH 2 ) 3 的首次合成NH 2 作为相应磷酸桥二糖的稳定类似物。关键的膦酸酯键是在光信条件下通过单糖结构单元的缩合获得的。此外,目标化合物的受保护前体经过适当设计以允许进一步延伸和合成更高的低聚物。

    Synthesis and High-Throughput Screening of N-Acetyl-β-hexosaminidase Inhibitor Libraries Targeting Osteoarthritis
    摘要:
    C1 Nitrogen iminocyclitols are potent inhibitors of N-acetyl-beta-hexosaminidases. Given hexosaminidases' important roles in osteoarthritis, we developed two straightforward and efficient syntheses of C1 nitrogen iminocyclitols from two readily available starting materials, D-mannosamine hydrochloride and the microbial oxidation product of fructose. A diversity-oriented synthetic strategy was then performed by coupling these core structures with various aldehydes, carboxylic acids, and alkynes to generate three separate libraries. High-throughput screening of the generated libraries with human N-acetyl-beta-hexosaminidases produced only moderate inhibitory activities. However, the synthetic approach and screening strategy for these compounds will be applied to develop new potent inhibitors of human N-acetyl-beta-hexosaminidases, particularly when combined with the structural information of these enzymes.

    glycosyl diethyl phosphites and 4,6-O-benzylidene-protected galactosyl diethyl phosphite each reacted with a variety of acceptor alcohols in the presence of a stoichiometric amount of Tf2NH in CH2Cl2 at −78 °C to afford the corresponding β-glycosides in good to high yields with complete stereoselectivity. Some experiments provided strong evidence that the corresponding oxazolinium ions are not responsible
