Tyrosine kinase inhibitors (TKIs) have achieved substantial clinical effects for cancer treatment while causing a number of adverse effects. Since hypoxia is an intrinsic difference between solid tumor and healthy tissues, one strategy to overcome the adverse effects of TKIs is to enhance the specificity of anti-tumor activity by selectively targeting hypoxic region of tumors. Herein, we designed and synthesized
酪氨酸激酶抑制剂(TKIs)在治疗癌症方面已经取得了可观的临床效果,同时引起了许多不利影响。由于缺氧是实体肿瘤和健康组织之间的固有差异,因此克服TKI不利影响的一种策略是通过选择性靶向肿瘤的缺氧区域来增强抗肿瘤活性的特异性。本文中,我们通过将3-硝基-1,2,4-三唑基团引入vandetanib的侧链上并修饰了苯胺部分,设计并合成了一系列新型的4-苯胺基喹唑啉衍生物。铅化合物10a和10g对EGFR和VEGFR-2激酶显示出有效的抑制活性。而且,与vandetanib相比,这两种化合物显示出在缺氧条件下增强了对A549和H446细胞的抗增殖活性,并显着下调了VEGF基因的表达。体内研究证实,与vandetanib相比,10a和10g不仅抑制了BALB / c-nu小鼠A549异种移植物中的肿瘤生长,而且还显着降低了与体重减轻相关的毒性。这些结果表明,EGFR / VEGFR-2双重抑制剂1
