Eight tridentate bipyrazole derivatives with different side arms have been prepared in one step and with good yields. The products were screened for their cytotoxic activity against three tumor cell lines—human breast cancer cell line MDA-MB231, human prostate cancer cell line PC3, and human colorectal cell line LoVo, by use of colorimetric MTT assay. Structure–activity relationships reflected the effect of substituted drugs. Among this series, two compounds had remarkable in-vitro antiproliferative activity against the LoVo cell line with IC50 values ranging from 2.6 to 2.7 μg ml−1. All the compounds had suitable drug-like characteristics according to Lipinski’s rule.
通过一步法合成且产率良好的八个具有不同侧臂的三齿双吡唑衍生物。利用MTT比色法测定产物对三类肿瘤细胞系的细胞毒活性——人乳腺癌细胞系MDA-MB-231、人前列腺癌细胞系PC3和人结直肠癌细胞系LoVo。结构-活性关系反映了取代药物的影响。在该系列中,有两种化合物对LoVo细胞系显示出显著的体外抗增殖活性,IC50值分别为2.6至2.7 μg ml−1。根据Lipinski规则,所有化合物都具有适合药物的特征。
