Herein, we report the development of a functional affinity-based small-molecule probe which is composed of a potent small-molecule NQO1 inhibitor 3d as the recognition group, a linker and the fluorophores group FITC. The probe exhibits good inhibitory activity of NQO1 and has been successfully used to label the protein in A549 cells at the micromolar level. These features make the probe favorable for
NQO1是一种二聚体黄素蛋白,与癌症密切相关,并在许多人类肿瘤细胞的细胞质中过度表达。鉴于蜂窝环境非常动态且具有通用性,因此对NQO1功能的进一步研究取决于对其进行特定检测的工具。当前,已经开发了几种基于活性的测定法来检测表达NQO1的癌组织。在此,我们报道了一种基于功能亲和力的小分子探针的开发,该探针由有效的小分子NQO1抑制剂3d作为识别基团,连接子和荧光团FITC组成。该探针显示出良好的NQO1抑制活性,并已成功用于微摩尔水平标记A549细胞中的蛋白质。这些特征使该探针适合于机理研究和癌症诊断生物标志物。
