We presented herien the rational design, synthesis, and photophysical property studies of the lysosome-targeted fluorescence FA probe NP-Lyso, an isopropyl group modified ortho-diaminonaphthalimide derivative. After the reaction of FA and ortho-phenylenediamine modified with the isopropyl group in NP-Lyso, the probe exhibited favorable features such as a large fluorescence enhancement, specific selectivity and high sensitivity for the detection of FA. More importantly, NP-Lyso could be used to detect and image endogenous FA in lysosomes. In light of these prominent properties, we envision that NP-Lyso will be an efficient optical imaging approach for investigating the biofunctions of FA in living systems.
我们在此展示了溶酶体靶向荧光叶酸(FA)探针NP-Lyso的合理设计、合成及光物理性质研究,NP-Lyso是一种异丙基修饰的邻二氨基萘二甲酰亚胺衍生物。在NP-Lyso中,FA与经异丙基修饰的邻苯二胺反应后,该探针表现出诸如荧光大幅增强、特异性选择性及对FA检测的高灵敏度等良好特性。更重要的是,NP-Lyso可用于检测溶酶体内的内源性FA并进行成像。鉴于这些突出特性,我们设想NP-Lyso将成为一种用于研究活体内FA生物功能的高效光学成像方法。
