Ten fused heterocyclic derivatives bearing the 2,6-di(subsituted phenyl)thiazolo[3,2-b]-1,2,4-triazoles as central rings were synthesized and structures of the compounds were established by analytical and spectral data using FTIR, EI-MS, 1H NMR and 13C NMR techniques. In vitro inhibitory activities of synthesized compounds on α-amylase, α-glucosidase and α-burylcholinesterase (α-BuChE) were evaluated
合成了以2,6-二(取代苯基)噻唑并[3,2-b] -1,2,4-三唑为中心环的十个稠合杂环衍生物,并通过FTIR分析和光谱数据确定了化合物的结构,EI-MS,1H NMR和13C NMR技术。使用纯化的酶分析方法评估了合成化合物对α-淀粉酶,α-葡萄糖苷酶和α-苯甲胆碱酯酶(α-BuChE)的体外抑制活性。化合物5c表现出强大的选择性α-淀粉酶抑制活性(IC50 =1.1μmol/ g)。与作为阳性参照的阿卡波糖(IC50 =4.7μmol/ g)相比,5g表现出对α-葡萄糖苷酶的优异抑制作用(IC50 =1.2μmol/ g)。发现化合物5i是针对α-BuChE的最有效衍生物,IC50为1.5μmol/ g,与(4.7μmol/ g)阳性对照得到的值相当(即 加兰他敏氢溴酸盐)。合成化合物的分子对接进入人类胰腺α-淀粉酶,肠麦芽糖酶-葡糖淀粉酶和神经元α-丁酰胆碱酯酶的结合位点,可以阐
