摘要

Herein, we report a novel lysosome targetable luminescent bioprobe derived from a europium coordination compound, namely Eu(pfphOCH(3)IN)(3)(DDXPO) 4 [where HpfphOCH(3)IN = 4,4,5,5,5-pentafluoro- 3-hydroxy-1-(1-(4-methoxyphenyl)-1H-indol-3-yl) pent-2-en-1-one and DDXPO = 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene oxide]. Notably, the newly designed europium complex exhibits significant quantum yield (Phi(overall) = 25 +/- 3%) and D-5(0) excited state lifetime (tau = 398 +/- 3 mu s) values under physiological pH (7.2) conditions when excited at 405 nm. Hence the developed europium complex has been evaluated for live cell imaging applications using mouse pre-adipocyte cell lines (3T3L1). Colocalization studies of the designed bio-probe with commercial Lysosome-GFP in 3T3L1 cells demonstrated the specific localization of the probe in the lysosome with a high colocalization coefficient (A = 0.83). Most importantly, the developed bioprobe exhibits good cell permeability, photostability and non-cytotoxicity.
