A series of novel 1,2,3-triazole-linked isosteviol derivatives were designed and synthesized via Huisgen-click reaction. Their cytotoxicities in vitro against HCT-116 and JEKO-1 cells were screened. The preliminary bioassays indicated that most of the title compounds exhibited noteworthy cytotoxic activities. Particularly, the compound 10b revealed the most potent inhibitory activities against HCT-116

生物测定表明,大多数标题化合物表现出值得注意的细胞毒活性。特别地,化合物10b显示出对HCT-116细胞最有效的抑制活性,IC50值为2.987±0.098μM,优于阳性对照
顺铂的(3.906±0.261μM)。基于这些
生物活性数据,进行了全息图定量结构-活性关系(HQ
SAR),并获得了具有良好预测能力(r2 = 0.848,q2 = 0.544和R2pred = 0.982)的统计可靠模型。此外,
