EGFR的过表达通常与晚期疾病和不良预后有关。在某些癌症中,Src与EGFR协同作用以促进增殖,存活,侵袭和转移。针对EGFR和Src的双靶标药物的开发具有针对这些癌症的治疗优势。基于分子对接和我们先前的研究,我们合理地设计了一系列新的氮杂ac啶衍生物作为有效的EGFR和Src双重抑制剂。大多数合成的氮杂ac啶对K562和A549细胞显示出良好的抗增殖活性。代表性化合物13b对K562和A549细胞显示nM IC 50值,并在10μM下以33.53%的抑制率抑制EGFR,在1μM下以72.12%的抑制率抑制Src。此外,复合13b可以抑制EGFR,p-EGFR,Src和p-Src的表达。此外,13b有效抑制肿瘤细胞的侵袭并诱导癌细胞凋亡。我们的研究表明,可将氮杂ac啶支架开发为新型的多靶点激酶抑制剂,用于癌症治疗。

Abstract An amide-assisted arene nitration is presented, and both mono- and dinitration of protected anilines could be effected by using NaNO2 and NaNO3 as the mono- and bisnitrating agents, respectively. This divergent synthesis is transition-metal- and acid-free, and features a broad substrate scope, low cost, and ortho–para selectivity. Graphical Abstract

oquinazoline derivatives bearing diarylamide moiety were designed, synthesized and evaluated as potent inhibitors of VEGFR-2kinase. Their in vitro antiproliferation activities against two human cancer cell lines Hep-G2 and MCF-7 have also been determined. Among them, compound 14b exhibited the most potent inhibitory activity against VEGFR-2 with IC50 value of 0.016 ± 0.002 µM and it showed the most
