the best lead for trifunctional inhibition against MAO A (0.34 μM), MAO B (0.26 μM), and AChE (52 μM), while 32 exhibited a lead for selective MAO A (0.12 μM) inhibition coupled to AChE (48 μM) inhibition. Computational analysis revealed that the malononitrile group can find an advantageous position with the aromatic cleft and FAD of MAO A or MAO B. However, the total binding energy can be handicapped
基于具有腈基的氨基杂环的单胺氧化酶(MAO)抑制特性,我们进行了系统的探索,以发现具有双重MAO和AChE抑制活性以及Aβ抗聚集特性的新型腈。合成并评估了83种含腈化合物,其中13种是新化合物。体外筛选显示,一种新化合物31对MAO A(0.34μM),MAO B(0.26μM)和AChE(52μM)的三功能抑制作用表现出最好的铅,而32表现出选择性MAO A(0.12μM)抑制与AChE(48μM)抑制耦合的先导。计算分析表明,丙二腈基团可以在MAO A或MAO B的芳族裂隙和FAD上找到有利的位置。但是,总的结合能可能会因配体分子扭曲和随后的破坏而造成的内部损失而受阻。共轭(MAO B中的32与共轭31相比)。共轭对于AChE以及丙二腈的亲水特性也很重要,丙二腈使该基团与水性环境紧密接触,见83。尽管31和32对Aβ1–42有影响该化合物非常弱,对63和65以及对新化合物75的影响表明
