inhibitor 86 (EKB-569). Three synthetic routes were used to prepare these compounds. They were prepared mostly by acylation of 6-amino-4-(arylamino)quinoline-3-carbonitriles with unsaturated acid chlorides or by amination of 4-chloro-6-(crotonamido)quinoline-3-carbonitriles with monocyclic or bicyclic anilines. The third route was developed to prepare a key intermediate, 6-acetamido-4-chloroquinoline-3-carbonitrile
一系列新的6,7-二取代的4-(芳基氨基)喹啉-3-甲腈衍生物可作为人类表皮生长因子受体2(HER-2)和表皮生长因子受体(EGFR)激酶的不可逆抑制剂发挥作用。准备好了。与我们的EGFR激酶抑制剂86(EKB-569)相比,这些化合物表现出增强的抑制HER-2激酶和HER-2阳性细胞生长的活性。使用三种合成途径来制备这些化合物。它们的制备主要是通过6-氨基-4-(芳基氨基)喹啉-3-腈与不饱和酰氯的酰化作用或通过4-氯-6-(巴豆酰胺基)喹啉-3-腈与单环或双环苯胺的胺化而制备的。开发了第三条路线来制备关键中间体,即6-乙酰氨基-4-氯喹啉-3-腈,该中间体涉及更安全的环化步骤。我们显示,在4-(芳基氨基)环的对位上附加一个大的亲脂基团会导致抑制HER-2激酶的效力提高。我们还显示了在迈克尔受体末端的碱性二烷基氨基对于活性的重要性,这归因于迈克尔加成的分子内催化作用。这与改善的水溶性一起
