Catenin tales: Fifteen naphthalene derivatives, including four new glucosides, eleutherinosides B–E, were obtained. Ten of these compounds inhibited transcription of TCF/β‐catenin in STF/293 cells. Compounds 2 and 9 inhibited the transcription of TCF/β‐catenin dose‐dependently and showed selective cytotoxicity against three colorectal cancer cell lines. The decrease of nuclear β‐catenin protein upon
连环蛋白的故事:获得了15种萘衍生物,包括4种新的葡糖苷,即亮皮苷B-E。这些化合物中有十种抑制了STF / 293细胞中TCF /β-catenin的转录。化合物2和9剂量依赖性地抑制TCF /β-catenin的转录,并显示出对三种结直肠癌细胞系的选择性细胞毒性。9处理后核β-catenin蛋白的减少导致了其对Wnt信号的抑制作用。
