assay, the derivatives were not as active as the positive control galantamine, but a general better activity was shown from the aromatic compounds. The best results were for 10, with 41.9% of inhibition (concentration of 150 μg/mL), and 9 with 31.6%. Docking analysis of compound 10 showed hydrogen bonds with residues Ser200 and His440 in the AChE catalytic gorge. All synthesized derivatives 2–15 presented
由于阿尔茨海默氏病(AD)是多因素疾病,因此应使用针对多种关键途径的药物来解决。一系列脂族(的2 - 8)和芳族(9 - 15)依达拉奉衍生物的合成,其特征在于,并用1,1-二苯基-2-苦基苯肼(DPPH)和2,2'-连氮基-双作为抗氧化剂评价-(3-乙基苯并噻唑啉-6-磺酸盐)(ABTS· +)测定法,以及乙酰胆碱酯酶(AChE)抑制剂。在两种抗氧化剂测定中,即使起始化合物依达拉奉具有更高的活性,最佳衍生物为5,其50%有效浓度(EC 50)分别为0.0301和0.8106 mM,然后为3(EC0.1920 mM和3.5311 mM中的50)。在AChE抑制试验中,衍生物的活性不如阳性对照加兰他敏,但芳香族化合物的活性通常更高。最佳结果为10,抑制率为41.9%(浓度为150μg/ mL),9为31.6%。化合物10的对接分析显示AChE催化峡谷中的残基Ser200和His440具有氢键。所有合成衍生物2
