It had been reported that some dioxygenated rings fusing with the quinazoline scaffold could lead to new EGFR inhibitors. Based on this, several kinds of oxygenated alkane quinazoline derivatives were synthetized and evaluated as EGFR inhibitors. Their antiproliferative activities were tested against four cancer cell lines: A431, MCF-7, A549, and B16-F10. Most derivatives could counteract EGF-induced
据报道,一些与喹唑啉支架融合的双加氧环可能会导致新的EGFR抑制剂。基于此,合成了几种氧化的烷烃喹唑啉衍生物,并评价其为EGFR抑制剂。测试了它们对四种癌细胞系的抗增殖活性:A431,MCF-7,A549和B16-F10。大多数衍生物可以抵消EGF诱导的EGFR磷酸化,其效价与参考化合物厄洛替尼相当。稠合的双加氧环的大小对于生物活性至关重要,并且七原子环衍生物19在酶促测定和细胞测定中均显示出强大的体外抑制活性。
