The natures of electron-donating groups as well as the bridge between them determine the fate of substituted 1,8-naphthalimide molecules in the excited state. An activity-based probe constructed from a selective peptide sequence, a reactive warhead, and the brightest green-emitting fluorophore displays impressive performance for thrombin protease detection in a newly constructed series of 1,8-naphthalimides.
供电子基团的性质以及它们之间的连接桥决定了取代 1,8-萘酰亚胺分子在激发态下的命运。从一个选择性的肽序列、一个反应性的弹头和最亮的绿色荧光团构建的一种基于活性的探针,在新构建的一系列 1,8-萘酰亚胺中显示出对凝血酶蛋白酶检测的优异性能。
