  Synthesis and biological evaluation of 4-arylcoumarins as potential anti-Alzheimer’s disease agents

  摘要：

  Alzheimer's disease (AD) is a progressive neurological degenerative disease that has complex pathogenesis. A variety of studies in humans indicate that several enzymes inhibitors can be useful in the treatment of AD, including acetylcholinesterase (AchE), butyrylcholinesterase (BuChE) and monoamine oxidase (MAO). Various substituted 4-arylcoumarin derivatives were synthesised, and their activity in vitro were investigated, including AChE/BuChE inhibitory activity, MAO inhibitory activity, and antioxidant activity. Most of the compounds were found to exhibit high inhibitory activity, and individual compounds have extremely excellent activities. Therefore 4-arylcoumarins provides an idea for drugs design for the development of therapeutic or preventive agents for AD.

  Various substituted neoflavonoid derivatives were synthesized using sulfated montmorillonite K-10 as a catalyst. This method is environmental friendly, sustainable and economical, convenient in isolation and purification processes, with little byproducts, using earth-abundant catalysts and has relatively high yield. Those neoflavonoid derivatives were screened for antioxidant, a-glucosidase inhibitory

  使用硫酸化的蒙脱石K-10作为催化剂合成了各种取代的新类黄酮衍生物。该方法是环境友好的，可持续的和经济的，使用丰富的地球催化剂，在分离和纯化过程中方便，副产物少，副产物少。筛选那些新类黄酮衍生物的抗氧化剂，α-葡萄糖苷酶抑制作用，醛糖还原酶2（ALR2）抑制作用和晚期糖基化终产物形成抑制作用。大多数化合物显示出显着的抗氧化剂和先进的糖基化终产物（AGE）形成抑制活性。有趣的是，在30种化合物中，8k和8l被发现比标准药物槲皮素具有更高的ALR2抑制活性。药理研究表明，具有相邻7,8-二羟基基团的新黄酮类化合物在抑制ALR2方面更有效。抗糖尿病活性研究表明，化合物8l和8m在体内与标准药物glibenclamide等效。总之，目标化合物81提供了用于开发糖尿病和糖尿病并发症的治疗剂或预防剂的潜在药物设计概念。
