proteins, biomolecules, and enzymes in living cells is an important goal for biologists, and fluorescence probes are powerful tools for this purpose. Because many target molecules are present in only trace amounts, high sensitivity is very important, and it is common to improve the sensitivity of fluorescence probes by focusing on high reaction velocity, K(d).

对活细胞中蛋白质、生物分子和酶之间相互作用的无创可视化和研究是生物学家的一个重要目标,而荧光探针是实现这一目的的有力工具。由于许多目标分子仅以痕量存在,因此高灵敏度非常重要,通常通过关注高反应速度 K(d) 来提高荧光探针的灵敏度。(Gee, KR; Archer, EA; Lapham, LA; Leonard, ME; Zhou, Z.; Bingham, J.; Diwu, Z. Bioorg. Med. Chem. Lett. 2000, 10, 1515-1518.) 到目前为止,我们基于上述概念设计合成了各种高灵敏度的荧光探针。(Gabe, Y.; Urano, Y.; Kikuchi, K.; Kojima, H.; Nagano, TJ Am. Chem. Soc. 2004, 126, 3357-3367.
