Herein we report the first small molecule that disrupts the survivin-Smac interaction taking place in mitochondria. The inhibitor, PZ-6-QN, was identified by initially screening a phenothiazine library using a fluorescence anisotropy assay and then conducting a structure-activity relationship study. Mutagenesis and molecular docking studies suggest that PZ-6-QN binds to survivin similarly to the known
在此,我们报道了第一个破坏线粒体中survivin-Smac相互作用的小分子。通过首先使用荧光各向异性测定法筛选吩噻嗪文库,然后进行结构-活性关系研究,鉴定了抑制剂PZ-6-QN。诱变和分子对接研究表明,PZ-6-QN与survivin的结合类似于已知的Smac肽AVPI。努力的结果还表明,PZ-6-QN对各种癌细胞表现出良好的抗癌活性。此外,基于细胞的机理研究为PZ-6-QN进入线粒体以抑制survivin-Smac相互作用并促进Smac和细胞色素c从线粒体释放到胞质溶胶中这一提议提供了证据,这一过程诱导了癌细胞的凋亡。全面的,
