In this work, a wide range of novel pyrazolo[4′,3′:5,6]pyrano[2,3‐b]quinolin‐5‐amines were synthesized as tacrine analogs. At first, reaction of 3‐methyl‐1‐phenyl‐1H‐pyrazol‐5(4H)‐one, aromatic aldehydes, and malononitrile gave 6‐amino‐4‐aryl‐3‐methyl‐1‐phenyl‐1,4‐dihydropyrano[2,3‐c]pyrazole‐5‐carbonitriles. Then, reaction of the latter compounds with cyclohexanone led to the formation of the title
在这项工作中,大范围的新的吡唑[4',3':5,6]吡喃并[2,3- b ]喹啉-5-胺合成为他克林的类似物。首先,将3-甲基-1-苯基-1 H-吡唑-5(4 H)-1 ,芳族醛和丙二腈反应,得到6-氨基-4-芳基-3-甲基-1-苯基-1, 4-二氢吡喃并[2,3- c ]吡唑-5-腈。然后,后一种化合物与环己酮反应导致标题化合物的形成。此外,还评估了它们的体外乙酰胆碱酯酶和丁酰胆碱酯酶抑制活性。有趣的是,与卡巴拉汀相比,它们中的大多数都具有良好的抑制活性。
