An acedan derivative containing Zn(II)–DPA has been developed as a two-photon probe for nucleoside phosphates, which shows enhanced fluorescence toward ATP and ADP at physiological pH 7.4 among other competing anions including AMP; the probe is permeable to cell membranes and thus can be directly used for two-photon imaging of ATP and ADP in live cells.
含有 Zn(II)-DPA 的乙酰衍生物已被开发为核苷磷酸的双光子探针,在生理 pH 7.4 以及包括 AMP 在内的其他竞争性阴离子中,其对 ATP 和 ADP 的荧光增强;该探针可渗透细胞膜,因此可直接用于活细胞中 ATP 和 ADP 的双光子成像。
