A series of novel 7‐alkoxyl substituted indolizinoquinoline‐5,12‐dione derivatives were synthesized. The cholinesterase inhibition assays indicated that most synthesized compounds exhibited good activity for acetylcholinesterase (AChE) and high selectivity index of AChE over butyrylcholinesterase (BuChE). Compound 12b exhibited the most potent AChE inhibitory activity with an IC50 value of 0.068 µM
合成了一系列新型 7-烷氧基取代的 indolizinoquinoline-5,12-dione 衍生物。胆碱酯酶抑制试验表明,大多数合成的化合物对乙酰胆碱酯酶 (AChE) 表现出良好的活性,并且 AChE 对丁酰胆碱酯酶 (BuChE) 的选择性指数较高。化合物 12b 表现出最有效的 AChE 抑制活性,IC50 值为 0.068 µM,选择性指数最高为 144。AChE 的动力学研究表明这些 indolizinoquinoline-5,12-dione 衍生物存在混合类型的抑制模式。分子对接研究表明,化合物 12b 可以与 AChE 的催化活性位点和外周阴离子位点结合。
