Two series of novel tricyclic oxazine and oxazepine fused quinazolines have been designed, synthesized and evaluated for their inhibitory activity against EGFR and HER2. Structure-activity relationship (SAR) of these compounds was discussed. From the SAR studies, we found that intramolecular cyclization which possessed a functional Michael acceptor group can enhance the antitumor activities. Compounds
已经设计,合成和评估了两个系列的新颖的三环恶嗪和奥氮平稠合的喹唑啉对EGFR和HER2的抑制活性。讨论了这些化合物的构效关系(SAR)。从SAR研究中,我们发现具有功能性Michael受体基团的分子内环化可以增强抗肿瘤活性。化合物1e和1h被鉴定为先导化合物,其对EGFR和HER2的有效抑制作用是批准的拉帕替尼药物的近3-4倍。这些化合物令人满意的理化性质也得到了ACD实验室的支持。此处提出的结果将促进新型EGFR和HER2双重抑制剂的开发。
