  Synthesis and Structure−Activity Relationships of 6,7-Disubstituted 4-Anilinoquinoline-3-carbonitriles. The Design of an Orally Active, Irreversible Inhibitor of the Tyrosine Kinase Activity of the Epidermal Growth Factor Receptor (EGFR) and the Human Epidermal Growth Factor Receptor-2 (HER-2)

  摘要：

  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.

  A series of new 6-substituted-4-(3-bromophenylamino)quinazoline derivatives that may function as irreversible inhibitors of epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor (HER-2) tyrosine kinases have been prepared. These inhibitors have, at the C-6 position, butynamide, crotonamide, and methacrylamide Michael acceptors bearing water-solublilizing substituents. These

  已经制备了一系列新的6-取代的4-（3-溴苯基氨基）喹唑啉衍生物，其可以用作表皮生长因子受体（EGFR）和人表皮生长因子受体（HER-2）酪氨酸激酶的不可逆抑制剂。这些抑制剂在C-6位具有带有水溶性增溶取代基的丁炔酰胺，巴豆酰胺和甲基丙烯酰胺迈克尔受体。这些化合物是通过将6-氨基-4-（3-溴苯基氨基）喹唑啉与不饱和酰氯或混合酸酐酰化而制备的。我们显示，由于迈克尔加成的分子内催化和/或质子化碱性基团的诱导作用，将碱性官能团附接到迈克尔受体上导致更大的反应性。加上改善的水溶性，产生具有增强的生物学特性的化合物。我们目前分子模型和实验证据，这些抑制剂与目标酶共价相互作用。一种化合物16a在裸鼠的人表皮样癌（A431）异种移植模型中显示具有出色的口服活性。
