Their chemical structures were confirmed by 1H NMR, LCMS, IR and elemental analysis. The antiproliferative effect of the compounds were evaluated in vitro using the MTT colorimetric method against one normal cell line (NF-103 skin fibroblast cells) and four humancancercelllines (MCF-7 breast carcinoma cell line, HepG-2 hepatocellular carcinoma cell line, HeLa cervix carcinoma cell line and HT-29
为了探索与哌嗪骨架有关的抗增殖作用,合成了几种1-苯甲酰基哌嗪衍生物8(a - d),9(a - d)和10(a - h)。哌嗪N末端官能团的变化导致形成三组化合物,分别带有磺酰基,酰胺和硫脲。通过1 H NMR,LCMS,IR和元素分析确认了它们的化学结构。在体外评估了化合物的抗增殖作用使用MTT比色法针对一种正常细胞系(NF-103皮肤成纤维细胞)和四种人类癌细胞系(MCF-7乳腺癌细胞系,HepG-2肝细胞癌细胞系,HeLa宫颈癌细胞系和HT-29)结肠癌细胞系)持续24小时。在这一系列中,四种化合物对所有四种细胞系均表现出令人感兴趣的生长抑制作用。
