    亲水,有力和选择性7取代的2-氨基喹啉作为改进的人类神经元一氧化氮合酶抑制剂。
    摘要:
    神经元型一氧化氮合酶(nNOS)是开发抗神经退行性药物的目标。大多数的nNOS抑制剂模仿升-精氨酸,生物利用度差。2-氨基喹啉显示出作为生物可利用的nNOS抑制剂的前景,但遭受人类nNOS抑制作用低,相对于人类eNOS的选择性低以及与其他CNS靶标的显着结合。我们的目标是通过(a)截短原始支架或(b)引入亲水基团以中断亲脂性,混杂的药效团并促进与人nNOS特异性His342的相互作用来提高人nNOS的效力和选择性,并减少脱靶结合。我们合成了截短的和极性的2-氨基喹啉衍生物,并针对重组NOS酶对其进行了测定。尽管苯胺和吡啶衍生物与His342相互作用,但苄腈赋予大鼠和人nNOS最佳的抑制作用。在氰基附近引入疏水性取代基和氨基喹啉甲基化都大大改善了同工型的选择性。最重要的是,这些修饰保留了Caco-2的通透性并减少了脱靶CNS的结合。
