A series of bis-pyrazole derivatives were designed and synthesized, and their antitumor effects in vitro and in vivo were investigated. Several compounds displayed good antiproliferative activity with IC50 values in low-micromolar range against three human cancer cell lines in vitro, superior to 5-FU. The most potent compound 10M selectively inhibited human hepatocellular carcinoma cells but not non-tumor
一系列双-吡唑衍生物的设计和合成,并且它们的抗肿瘤作用在体外和体内进行了研究。几种化合物在体外对三种人类癌细胞系均表现出良好的抗增殖活性,其IC 50值在低微摩尔范围内,优于5-FU。最有效的化合物10M在体外选择性抑制人肝癌细胞,但不抑制非肿瘤肝细胞增殖,并通过以浓度依赖性方式裂解PARP和caspase-3来显着触发SMMC-7721细胞凋亡。进一步的研究表明,强效活性对细胞生长具有抑制和凋亡诱导作用。10M与DNA损伤和p53信号通路的激活有关。此外,10M表现出对小鼠的低急性毒性,并且在体内对肝癌肿瘤具有显着的生长抑制作用。
