Tilorone is an interferon inducer with anticancer activity. Twenty-two novel tilorone analogs were synthesized by improvements of fluorenone skeleton, side chains and amino groups to screen new anticancer agents. In vitro evaluation showed that ten new compounds had better anticancer activities than tilorone. Among them, 2c (IC50 < 7 μM against cancer cell lines and IC50 > 35 μM against non-cancer
噻洛酮是具有抗癌活性的干扰素诱导剂。通过改进芴酮骨架,侧链和氨基,合成了二十二种新颖的tilorone类似物,以筛选新的抗癌药。体外评估表明,十种新化合物具有比tilorone更好的抗癌活性。其中,图2c(IC 50 <7个μM针对癌细胞系和IC 50 > 35μM对非癌细胞系)和图5d(IC 50 <10μM的对癌症细胞系和IC 50 针对非癌细胞系> 53μM)表现出最佳的抗癌活性和选择性。通过分子操作环境(MOE)对高活性化合物进行了药效学建模,以生成用于化合物设计的可视化模型,以供将来研究之用。
