Small molecule tyrosine kinase inhibitors (TKIs) targeting at epidermal growth factor receptor (EGFR) in recent years have made great progress in the treatment of advanced non-small cell cancer (NSCLC). Although as the first-line treatment for sensitizing EGFR mutation-positive metastatic NSCLC, gefitinib has also behaved quite a lot of side effect and EGFR tolerance. Herein, a novel series of 7-bromo-1
近年来,针对表皮生长因子受体(EGFR)的小分子酪氨酸激酶抑制剂(TKIs)在晚期非小细胞癌(NSCLC)的治疗中取得了巨大进展。尽管作为增敏EGFR突变阳性转移性NSCLC的一线治疗药物,吉非替尼还具有相当多的副作用和EGFR耐受性。本文设计合成了一系列新型的7-溴-1,4-二氢噻吩并[3',2':5,6]硫代吡喃并[4,3-c]吡唑-3-羧酰胺衍生物,并对其抑制作用进行了筛选。 3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四氮唑比色法检测EGFR高表达的人肺腺癌细胞系A549和人大细胞肺癌细胞NCI-H460的活性。计算出的IC 50值已报告。化合物8H展示了最有效的抑制活性(IC 50 = 9.57±2.20微摩尔大号-1为A549和IC 50 = 13.04±1.21微摩尔大号-1为NCI-H460),与阳性对照吉非替尼(IC 50 = 8.58 ±1.65微摩尔大号-1为A549和IC
