将二吡啶基乙基胺(DPA)与芘缩合还原后得到1-(芘-1-基)-N,N-双(吡啶-2-基甲基)乙胺(PYPA)可用作Zn2+探针.在焦磷酸(PPi)存在下MeOH/H2O(3∶2,V/V,pH 7.20,HEPES 1.0 mmol/L)缓冲液中PYPA对Zn2+显示出高度专一性,加Zn2+后20 s在383 nm处荧光发射可达最大值,且检测不受各种阳离子或阴离子的干扰,其检测极限可低至30 nmol/L.活细胞成像研究表明PYPA可用于人肝细胞L-02中Zn2+荧光标记.

A pyrene derivative PYPA, namely, 1-(pyren-1-yl)-N,N-bis(pyridin-2-ylmethyl)methanamine (PYPA), was synthesized to develop a chemosensor. The studies show that PYPA exhibits high sensitivity and selectivity toward Zn2+ over many other metal cations in the presence of pyrophosphatic acid (PPi). It has a low detection limit of 0.030 nmol/L. Detection of Zn2+ was not interfered by various cations or anions. In the presence of PPi, over a 8-fold fluorescence enhancement at 383 nm was observed within 20 s. Cell studies further demonstrated that PYPA can be a potential probe to detect Zn2+ in human liver cells (L-02).

Key words: pyrene derivative, Zn2+ fluorenscent probe, living cell image
