A near-infrared fluorescent probe has fluorescence in the near-infrared region. Like CaSiR-1, the probe has rhodamines as the fluorescent mother nucleus and accumulates in the cytoplasm. The probe makes it possible to visualize concentration fluctuations in metal ions, such as calcium ions, within the body. The fluorescent probe includes a compound represented by the following general formula or a salt of the compound:
一个近红外荧光探针在近红外区域有荧光。像CaSiR-1一样,该探针以
罗丹明作为荧光母核,并在细胞质中积累。该探针使得可视化体内
金属离子,如
钙离子的浓度波动成为可能。荧光探针包括由以下通用公式表示的化合物或该化合物的盐:
