efficient fluorescent probes for detecting the overexpressed Mcl-1 protein in living cells is imperative for the diagnosis and treatment of cancers. In this paper, a new UMI-77 based fluorescent probe (DNSH), was synthesized and characterized. DNSH bound to the hydrophobic pockets of Mcl-1 protein tightly and the binding affinity was 20-fold higher than that of previous developed Mcl-1 probe. DNSH exhibited
开发用于检测活细胞中过度表达的 Mcl-1 蛋白的有效荧光探针对于癌症的诊断和治疗至关重要。在本文中,合成并表征了一种新的基于 UMI-77 的荧光探针 ( DNSH )。DNSH与 Mcl-1 蛋白的疏水口袋紧密结合,结合亲和力比以前开发的 Mcl-1 探针高 20 倍。DNSH对 Mcl-1 蛋白而不是其他蛋白表现出特异性荧光反应。在Mcl-1蛋白存在的情况下可以开启DNSH的荧光发射。此外,荧光共定位实验表明DNSH可成功用于人前列腺癌细胞中线粒体 Mcl-1 蛋白的成像,无需洗涤过程。这些结果表明DNSH可能会在生物学研究中找到有用的应用,例如跟踪活生物标本中的 Mcl-1 蛋白。
