We synthesized (+)-decursin derivatives substituted with cinnamoyl- and phenyl propionyl groups originating from (+)-CGK062 and screened them using a cell-based assay to detect relative luciferase reporter activity. Of this series, compound 8b, in which a 3-acetoxy cinnamoyl group was introduced, most potently inhibited (97.0%) the Wnt/β-catenin pathway. Specifically, compound 8b dose-dependently inhibited
我们合成了被源自(+)-CGK062的肉桂酰基-和苯基丙酰基取代的(+)-递精蛋白衍生物,并使用基于细胞的测定法筛选了它们,以检测相对荧光素酶报道分子的活性。在该系列化合物中,其中引入了3-乙酰氧基肉桂酰基的化合物8b最有效地抑制了Wnt /β-catenin途径(97.0%)。具体而言,化合物8b在HEK293报告细胞中剂量依赖性地抑制Wnt3a诱导的β-catenin反应转录(CRT)表达,并增加β-catenin降解。此外,化合物8b以浓度依赖性方式抑制下游β-连环蛋白靶基因cyclin D1和c-myc的表达,并抑制PC3细胞的生长。
