effects with IC50 values ranging from 9.01 to 32.39 µM. The most potent was identified as 8-amino-10-(4-bromophenyl)-5‑hydroxy-4-methyl-2-oxo-2,10-dihydropyrano[2,3-f]chromeno-9-carbonitrile. In silico studies using human recombinant acetylcholinesterase (PDB: 4EY7) showed important proximities between the NH2 group of this compound and E202 in AChE, between W86 and the OH-5 group, between W86 and the aromatic
阿尔茨海默病是世界上最普遍的神经退行性疾病之一。到目前为止,用于控制这种疾病的药物已被开发用于靶向乙酰胆碱酯酶 (AChE)。为了确定可以有效抑制这种酶的新药效团,针对 AChE 评估了属于查尔酮、吡喃色素、色烯、吡喃并吡唑和二氢吡啶的 72 种化合物库。其中 19 种化合物是新报道的,在测试的化合物中,有 7 种带有吡喃色素骨架的化合物显示出抑制作用,IC 50值范围为 9.01 至 32.39 µM。最有效的是 8-amino-10-(4-bromophenyl)-5-hydroxy-4-methyl-2-oxo-2,10-dihydropyrano[2,3- f ]chromeno-9-carbonitrile。计算机使用人重组乙酰胆碱酯酶 (PDB: 4EY7) 的研究表明,该化合物的 NH 2基团与 AChE 中的 E202 之间、W86 和 OH-5 基团之间、W86 和芳香族双环系统之间具有重要的接近性(π-π
