Abstract

A series of of 6,7-disubstituted-4-anilinoquinoline-3-carbonitrile derivatives that function as irreversible inhibitors of EGFR and HER-2 kinases have been prepared. These inhibitors have, at the 6-position, butynamide, crotonamide, and methacrylamide Michael acceptors bearing water-solublilizing substituents. These compounds were prepared by acylation of 6-amino-4-(arylamino)quinoline-3-carbonitriles with unsaturated acid chlorides or mixed anhydrides. We performed competitive reactivity studies showing that attaching a dialkylamino group onto the end of the Michael acceptor results in compounds with greater reactivity due to intramolecular catalysis of the Michael addition. This, along with improved water-solubility results in compounds with enhanced biological properties. We present molecular modeling results consistent with the proposed mechanism of inhibition. One compound, 5 (EKB-569), which shows excellent oral in vivo activity, was selected for further studies and is currently in phase I clinical trials for the treatment of cancer.

摘要

已制备出一系列6,7-二取代-4-苯胺基喹啉-3-腈衍生物,它们作为表皮生长因子受体(EGFR)和人表皮生长因子受体2(HER-2)激酶的不可逆抑制剂发挥作用。这些抑制剂在6位含有带有水溶性取代基的丁炔酰胺、巴豆酰胺和甲基丙烯酰胺迈克尔受体。这些化合物是通过6-氨基-4-(芳基氨基)喹啉-3-腈与不饱和酰氯或混合酸酐的酰化反应制备的。我们进行了竞争反应性研究,结果表明,由于迈克尔加成的分子内催化作用,在迈克尔受体末端连接二烷基氨基会导致化合物具有更高的反应性。这与改善的水溶性一起,使得化合物具有增强的生物学特性。我们给出了与所提出的抑制机制一致的分子模拟结果。一种表现出优异口服体内活性的化合物5(EKB-569)被选作进一步研究对象,目前正处于治疗癌症的I期临床试验阶段。
