A series of novel pyrano[3,2-a]phenazine derivatives (1a-1r and 2a-2q), designed as hybrid molecules of phenazine and pyran pharmocophores, were facilely synthesized in two steps with 77-93% overall yields in this study. Cytotoxic evaluation indicates that many compounds exhibited cytotoxicity against HCT116, MCF7, HepG2 and A549 cancer cell lines in vitro, in which compounds 1c, 1i, 2e, and 2l were
在本研究中,分两步轻松合成了一系列新颖的吡喃并[3,2-a]吩嗪衍生物(1a-1r和2a-2q),它们是吩嗪和吡喃药物色谱的杂交分子,总产率为77-93% 。细胞毒性评估表明,许多化合物在体外均表现出对HCT116,MCF7,HepG2和A549癌细胞的细胞毒性,其中化合物1c,1i,2e和2l被发现对HepG2癌细胞具有优异的抗增殖活性。因此,确定了四种化合物在体内皮下植入的异种移植小鼠(H22H8D8细胞)的抑制作用以及体外拓扑异构酶I和IIα的抑制活性(HepG2细胞)。显着地,化合物1i在体内和体外均显示出比阳性对照药物更有效的作用。进一步针对体外HepG2细胞的机制研究表明,化合物1i上调p53和p21的表达,从而抑制cyclin B和CDK1的表达,并使HepG2细胞停滞在G2 / M期。同时,用化合物1i处理后,Bax / Bcl-2比例显着增加,细胞色素C从线粒体释放到细胞
