azaacridine derivatives as potent EGFR and Src dual inhibitors. Most of the synthesized azaacridines displayed good antiproliferative activity against K562 and A549 cells. The representative compound 13b showed nM IC50 values against K562 and A549 cells, and inhibited EGFR at inhibition rate of 33.53% at 10 μM and Src at inhibition rate of 72.12% at 1 μM. Furthermore, compound 13b could inhibit the expression
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。
