Two series of novel tricyclic oxazine and oxazepine fused quinazolines have been designed and synthesized. The in vitro antitumor effect of the title compounds was screened on N87, A431, H1975, BT474 and Calu-3 cell lines. Compared to gefitinib and erlotinib, compounds 1a-1h were found to demonstrate more potent antitumor activities. Several derivatives could counteract EGF-induced phosphorylation
设计并合成了两个系列的新型三环恶嗪和奥氮平稠合的喹唑啉。在N87,A431,H1975,BT474和Calu-3细胞系上筛选了标题化合物的体外抗肿瘤作用。与吉非替尼和厄洛替尼相比,发现化合物1a-1h具有更强的抗肿瘤活性。几种衍生物可以抵消EGF诱导的细胞中EGFR的磷酸化,其效力与参考化合物相当。选择化合物1a-1f,1h用于进一步评估EGFR和HER2的体外激酶抑制活性。化合物1c-1f,1h有效抑制EGFR和HER2的体外激酶活性,其功效与吉非替尼和厄洛替尼相似。
