Eleven glycosyl coumarylthiazole derivatives are synthesized by cyclization and condensation of glycosyl thiourea with 3-bromoacetyl coumarins in ethanol. The reaction conditions are optimized and good yields of products (80%–95%) are obtained. The structures of all new products were confirmed by IR, 1H and 13C NMR, and by HRMS (electrospray ionization). The in vitro acetylcholinesterase (AChE) inhibitory
通过糖基硫脲与3-溴乙酰基香豆素在乙醇中的环化和缩合反应,合成了11种糖基香豆基噻唑衍生物。优化了反应条件,并获得了良好的收率(80%–95%)。所有新产品的结构均通过IR,1 H和13 C NMR以及HRMS(电喷雾电离)确定。在体外乙酰胆碱酯酶抑制这些新化合物的活性由Ellman氏方法进行测试。其中,N-(2-乙酰氨基-3,4,6-三-O-乙酰基-2-脱氧-β - D-吡喃吡喃糖基)-4-(6-硝基香豆基)-1,3-噻唑-2-胺在体外显示出最佳活性AChE抑制率为58%,IC 50值为12±0.38μg/ mL。
