Series of novel alizarin and phosphoryl amino acid scaffold (4a–4d, 8a–8d) were synthesized and evaluated for the suppression of cancer cell proliferation in vitro against MGC-803, HepG2, T24, NCI-H460, and SK-OV-3 cell lines by standard 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay compared with commercial anticancer drug doxorubicin. Interestingly, all newly synthesized
合成了一系列新型茜素和磷酸氨基酸支架(4a – 4d,8a – 8d),并评估了其在体外对MGC-803,HepG2,T24,NCI-H460和SK-OV-3癌细胞增殖的抑制作用。通过标准3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四氮唑(MTT)分析与商业抗癌药阿霉素进行比较。有趣的是,与茜素相比,所有新合成的化合物均表现出相对较高的细胞毒性,而对人正常肝细胞系HL-7702细胞的毒性却较低。特别是化合物8d对带有IC 50的SK-OV-3细胞表现出最佳的细胞毒性7.09 µM,比药物阿霉素稍差。代表性化合物8d在SK-OV-3细胞中的细胞凋亡诱导活性表明,该化合物的抗癌活性取决于通过调节Bcl-2家族成员,激活caspase-9和caspase-3的癌细胞凋亡。细胞周期分析证实,化合物8d主要在G2期阻滞SK-OV-3细胞。此外,进行了分子对接研究,将化合物8d定位于端粒
