    摘要:
    香豆素具有芳香基团并表现出丰富的活性,例如抗氧化、预防哮喘和防腐作用。此外,香豆素衍生物通常具有良好的溶解性、低细胞毒性和优异的细胞渗透性。在我们的研究中,我们合成了桥连甲基他克林(BMT)化合物,其具有经典的他克林(THA)药效团结构。基于活性亚结构拼接原理,我们将BMT作为引物化合物,并通过将香豆素引入BMT中合成了香豆素-BMT杂交物。在这项工作中,我们合成了21种新的BMT和香豆素的杂交物,并评估了它们对AChE的抑制活性。所有获得的化合物均表现出优越的抑制活性。化合物8b是最活跃的化合物,其Ki值为49.2 nM,高于加兰他敏(GAL)但低于THA。分子对接的结果表明,化合物8b的最高结合自由能为-40.43 kcal/mol,这与计算的Ki值呈现相同的趋势。

    The present invention relate to a novel silane coupling agent and a medical and/or dental curable composition comprising the same. It is an object of the present invention to provide a novel silane coupling agent that imparts high affinity to a radical polymerizable monomer, thereby imparting high mechanical strength, flexibility and durability when used for a medical and/or dental curable composition, and an inorganic filler surface-treated with the novel silane coupling agent and a novel medical and/or dental curable composition. A silane coupling agent including repeating units such as a urethane bond and polyethylene glycol (ether bond) at a specific position is used.

    Hydrobromic acid was found to be a unique catalyst in CC bond‐forming reactions with ketene dithioacetals. Distinctly different from other acids (including Lewis and Brønsted acids), the remarkable catalytic performance of hydrobromic acid in catalytic amounts was observed in the “acid”‐catalyzed reactions of readily available functionalized ketene dithioacetals 1 with various electrophiles.
