this research work is to prepare readily soluble synthetic analogues of naturally occurring 3-O-flavonol glycosides and then investigate the influence of various substituents on biological properties of synthetic compounds. In this context, a series of varyingly substituted 3-O-flavonol glycosides have been designed, synthesized and characterized efficiently. The structures of synthetic molecules were
这项研究工作的主要目的是制备天然存在的3- O-黄酮醇糖苷的易溶合成类似物,然后研究各种取代基对合成化合物生物学特性的影响。在这种情况下,已经有效地设计,合成和表征了一系列不同取代的3- O-黄酮醇糖苷。红外,1 H,13 C NMR和ESI-MS光谱技术明确证实了合成分子的结构。还通过X射线衍射分析来分析化合物22的结构。对所有合成化合物(21 – 30)进行了体外评估对胆碱酯酶的抑制潜力。结果表明,大多数衍生物是乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BChE)的有效抑制剂,IC 50值的程度不同。为了探索它们与AChE和BChE酶活性口袋的结合行为,分子对接研究进一步鼓励了实验结果。实验和理论结果是相互平行的。
