64 and 0.44 μM, respectively, and exhibit good selectivity for β-catenin/Tcf over β-catenin/E-cadherin and β-catenin/adenomatous polyposis coli (APC) PPIs. The 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2 H-tetrazolium (MTS) cell viability assays revealed that 56, the ethyl ester of 53, was more potent than 53 in inhibiting viability of most of the Wnt/β-catenin hyperactive
β-catenin/ T细胞因子(Tcf)蛋白质-蛋白质相互作用(PPI)在β-catenin信号通路中起着至关重要的作用,而该信号通路在许多癌症和纤维化中均被过度激活。基于旨在靶向β-catenin的Tcf4 G13ANDE17结合位点的化合物1,进行了广泛的结构-活性关系研究。结果,发现化合物53和57分别破坏Ki-值为0.64和0.44μM的β-catenin/ Tcf PPI,并且相对于β-catenin/ E-cadherin和β-catenin/ E-cadherin表现出良好的选择性。 β-catenin/腺瘤性息肉病(APC)PPI。3-(4,5-二甲基噻唑-2-基)-5-(3-羧基甲氧基苯基)-2-(4-磺基苯基)-2 H-四唑(MTS)细胞活力测定显示56,53的乙酯,在抑制大多数Wnt /β-catenin过度活跃的癌细胞的生存力上,它比53更有效。进一步的基于细胞的研究表明56破坏了β-catenin/
