Fluorimetric study of the interaction between nicotinamide adenine dinucleotide phosphate and tetracycline–europium complex and its application

Artificial Receptors for the Recognition of Phosphorylated Molecules

“…655 These researchers also reported the detection of NADP using a tetracycline ligand ( 597c) at concentrations as low as 6.9 × 10 -8 M at pH 7.6. 656 Duerkop and co-workers studied the effect of inorganic phosphate on the luminescence of the europium(III) tetracycline complex ( 597c) . 657 Quenching was observed to be linear with phosphate concentration over the range of 5 × 10 -6 - 7.50 × 10 -4 M at neutral pH.…”

Luminescence Nucleotide/Eu3+ Coordination Polymer Based on the Inclusion of Tetracycline

“…So, no luminescence from AMP/Eu can be observed. Tetracycline is an ideal ligand for Eu 3+ . It contains β-diketonate configuration that can coordinate to Eu 3+ through O atoms of carbonyl group and absorb energy to sensitize the emission of Eu 3+ (antenna effect).…”

Sensing of Phosphate and ATP by Lanthanide Complexes in Aqueous Medium and Its Application on Living Cells

“…Compared to Eu-TC, [68][69][70] the present complexes are found to have ten to fifteen fold superior sensitivity towards ATP. The low analyte detection limit (DL) achieved in the present work, thus stands unique among various enzymatic [71][72][73] and electrochemical methods. [74] The strong Stern-Volmer constant in the order of 10 6 observed in the present case towards ATP with DL 0.2 μM shown by complex 2, is considered to be highly important.…”
