A Quinoline-Based Ratiometric and Reversible Fluorescent Probe for Cadmium Imaging in Living Cells

Abstract: We report a novel ratiometric and reversible fluorescent probe for Cd(2+) detection utilizing a 6-(dimethylamino)quinaldine derivative as the fluorophore and a 2-hydrazinopyridine derivative as Cd(2+) chelator. This ratiometric fluorescent probe possesses favorable photophysical properties. It shows a large (55 nm) red-shift from 515 nm to 570 nm in the emission spectrum. Moreover, this probe also exhibits an excellent linear relationship of fluorescence intensity ratio (F570/F515) (R(2)=0.989) vs. Cd(2+) conc… Show more

“…Liu et al ( Liu et al, 2010 ) developed DBITA, a ratiofluorescent sensor that can be used for the recognition of Cd 2+ in live cells or aqueous media, with a Cd 2+ -induced emission redshift of 53 nm ( Figure 9B ). Sun et al ( Sun et al, 2016 ) reported a ratio-measured and reversible fluorescent probe for the recognition of Cd 2+ in living cells that was based on a 6-(dimethylamino) quinaldine derivative. For Cd 2+ in living human cells, Jiang et al ( Jiang et al, 2014 ) developed a novel fluorescence probe (L) for C-3-symmetric Schiff alkaloids on the basis of 8-hydroxy-2-methylquinoline.…”

La química de coordinación depende de la geometría y del número de coordinación que forma parte del complejo.…”

“…141 Para muestras biológicas tales como células vivas, la quinolina también ha sido empleada para detección de Zn 2+ , glutatión y cisteína en mitocondrias entre otros. 164,171,172 Los fluoroforos derivados de quinolina (8-aminoquinolina, hydroxyquinolina, isoquinolina) han sido usados para el desarrollo de sensores para detección de Zn 2+ porque son altamente solubles en agua y muestran buena selectividad con el Zn 2+ . En el desarrollo de estos sensores se considera la selectividad del Cd 2+ =.…”
