synthetic compounds with interesting biological activities. Inspired by their structural feature, a total of 49 1,3-diaryl propane-based polyphenols were designed and synthesized through Claisen rearrangement reaction. New compounds were initially assessed for their anti-proliferative activities against various cancer cell lines (PC-3, U87MG, U251, HCT116) at a concentration of 50 μM, and the results
白藜芦醇、和厚朴酚、去甲二氢愈创木酸等多酚广泛存在于天然产物或具有有趣生物活性的合成化合物中。受其结构特征的启发,通过克莱森重排反应设计并合成了总共49种1,3-二芳基丙烷基多酚。初步评估了新化合物在 50 μM 浓度下对各种癌细胞系(PC-3、U87MG、U251、HCT116)的抗增殖活性,结果指导了该系列化合物的 SAR。针对七种癌细胞系(选择了另外三种结肠癌细胞系,即 COLO205、HT29 和 SW480)进一步筛选选定的化合物,鉴定出两种先进的先导化合物 2t 和 3t,其 IC 50 值范围为 8.2 ± 0.1至19.3 ± 1.9微米。两种化合物还以剂量和时间依赖性方式显示出针对 COLO205 的有前景的抗增殖活性。此外,2t和3t在COLO205异种移植小鼠模型中表现出良好的抗肿瘤功效,TGI值在38%至58%之间。这些结果值得对这一系列化合物进行进一步研究。
