    摘要:
    已证明丙酸芳基酯的氨解和碱水解是通过正常的亲核取代机理进行的。母体丙烯酸酯不会发生“扩展的” E 1cB水解机理,涉及氢氧根离子侵蚀β碳,然后从所得碳负离子中排出酚酸根离子。由于氰基对中间碳负离子的稳定作用,2-氰基-3-(4-甲氧基苯基)丙酸酯的水解具有“扩展的” E 1cB机理。

    铜绿假单胞菌 半亲和性低亲和力凝集素LecA竞争性结合测定的开发和优化†
    摘要:
    革兰氏阴性菌铜绿假单胞菌的感染导致免疫受损的患者和囊性纤维化患者的高死亡率。病原体可以从浮游生物转变为生物膜,从而保护自己免受抗生素治疗并宿主免疫防御以建立慢性感染。细菌蛋白LecA,一种C型凝集素,是一种致病因子,是生物膜形成不可或缺的组成部分。LecA及其碳水化合物配体的抑制作用导致生物膜质量降低,这可能是治疗的潜在致命弱点。在这里,我们报告与LecA的荧光偏振为基础的竞争性结合测定法的发展和优化,用于筛选潜在的抑制剂。由于D的亲和力低对于LecA-半乳糖,优化荧光配体以减少测定中的蛋白质消耗。使用一组已知的LecA抑制剂验证了该测定,并获得了与已知K d值高度吻合的IC 50值。最后,我们采用了优化的检测方法来筛选合成的硫代半乳糖苷和天然血型抗原的集合,并报告它们的结构-活性关系。此外,我们评估了LecA的多价荧光测定探针,并报告了其在抑制测定中的适用性。

  • Diazepinium perchlorate: a neutral catalyst for mild, solvent-free acetylation of carbohydrates and other substances
    作者:Santosh Kumar Giri、Rajesh Gour、K. P. Ravindranathan Kartha
    DOI:10.1039/c6ra28882k
    日期:——
    protecting groups such as TBDMS/TBDPS/Tr ethers and isopropylidene/benzylidene acetals present on a substrate unaffected. Regioselective hydroxyl protection in partially protected carbohydrate derivatives/polyhydroxylic compounds was possible and was proved to be a convenient time-saving alternative to the conventional synthesis of such compounds. Easy preparation of the catalyst, mild reaction conditions
    二氮杂嗪,一种具有优异稳定性的基本中性的有机盐,已被发现非常适用于游离的以及部分保护的糖,醇和其他醇以及胺的乙酰化。高氯酸二氮杂pin鎓催化的乙酰化反应温和,无有机和无溶剂,并且不影响底物上存在的对酸敏感的保护基团,例如TBDMS / TBDPS / Tr醚和异亚丙基/亚苄基乙缩醛。在部分受保护的碳水化合物生物/多羟基化合物中进行区域选择性羟基保护是可行的,并被证明是常规合成此类化合物的一种省时的简便方法。容易制备催化剂,温和的反应条件和对环境有益的方案是该反应的显着特征。苯酚苯硫酚的乙酰化反应所获得的结果可以通过DFT计算获得的局部亲核指数来合理化。

    Experimental evidence is provided for p-methylbenzyl-D-galactonoamidine to function as a true transition state analog for the enzymatic hydrolysis of aryl-β-D-galactopyranosides by β-galactosidase (A. oryzae). The compound exhibits inhibition constants in the low nanomolar concentration range (12–56 nM) for a selection of substrates. Along these lines, a streamlined synthetic method based on phase-transfer
