The recent emphasis on understanding the myriad roles of zinc in both normal and diseased cells and tissues has placed an ever increasing demand on methods for sensitive and selective methods for real-time monitoring of free Zn^(2+) in complex biological samples. Chelation-enhanced fluorescent sensors for zinc, based on fluorophores such as quinoline, dansyl, fluorescein, and anthracene, have been
最近对理解锌在正常和患病细胞和组织中的无数作用的重视已经对用于实时监测复杂生物样品中游离 Zn^(2+) 的灵敏和选择性方法提出了日益增长的需求。已经报道了基于诸如喹啉、丹磺酰、荧光素和蒽等荧光团的锌螯合增强荧光传感器。虽然这些试剂中的每一种都有独特的优势,但仍然存在灵敏度、选择性和特异性问题,这些问题可以通过易于合成操作的替代发色团来解决。在此,我们报告了 8-羟基-2-甲基喹啉 (Oxn) 单元的系统化学修饰,作为开发采用螯合增强荧光的新传感器的基础。特别是,
