A series of novel ligustrazine-chalcone hybrids were synthesized and evaluated for their in vitro and in vivo antitumor activities. The results showed that most of these compounds exhibited significant in vitro cytotoxicity against MDA-MB-231, MCF-7, A549 and HepG2 cell lines with IC50 values as low as sub-micromole. Among them, compounds 6c and 6f possessed better comprehensive characteristics for
合成了一系列新的川芎嗪-查尔酮杂化物,并评估了它们的体外和体内抗肿瘤活性。结果表明,这些化合物中的大多数对 MDA-MB-231、MCF-7、A549 和 HepG2 细胞系表现出显着的体外细胞毒性,IC 50值低至亚微摩尔。其中,化合物6c和6f对MDA-MB-231 (IC 50 : 6c , 1.60±0.21μM; 6f , 1.67±1.25 μM)和MCF-7 (IC 50 : 6c , 1.41±0.23μM;6f, 1.54±0.30 μM)。它们还以浓度和时间依赖性方式对上述两种细胞系显示出有效的集落形成抑制能力,以及通过伤口愈合试验以浓度依赖性方式显着抑制此类细胞系迁移的能力。值得注意的是,化合物6c能以浓度依赖性方式显着诱导MDA-MB-231细胞凋亡,抑制MDA-MB-231细胞生长周期的转变, 阻断细胞生长周期在G0/G1期。此外,化合物6c 的体内抗增殖试验在 TNBC
