Nanomolar pyrophosphate detection in water using a zinc-terpyridine receptor and its applications in antiproliferative and antioxidant activity

A simple copper(ii) dppy-based receptor for sensing of l-cysteine and l-histidine in aqueous acetonitrile medium

“…Both absorption spectral titrations demonstrate the sensitivity of the CuCl 2 L receptor towards minute changes in Cys and His concentrations. The detection limits 92–94 for Cys and His were calculated to be 0.33 μM and 1.40 μM, respectively, indicating the high sensitivity of the CuCl 2 L receptor for these analytes. The linear relationships found between the absorbance and concentration of Cys and His are shown in Fig.…”

Investigation of protein/DNA binding, and in vitro cytotoxicity of novel Cu(ii) and Zn(ii)-dipyrazinyl pyridine complexes

“…5–8 The biological applications of terpyridines also include DNA and protein binding. 5 The significance of terpyridines and their metal complexes extends to diverse areas, ranging from sensing, 9–11 self-assembly, 12–15 dye-sensitized solar cells, 16 and halogen bonding, 17,18 to organic light-emitting devices. 19 Like terpyridines, dipyrazinyl pyridines (dppy) are expected to possess comparable biological prowess due to their analogous NNN-pincer type structure and additional nitrogen atoms in the pyrazine moieties.…”

Role of the Environment Polarity on the Photophysical Properties of Mesogenic Hetero-Polymetallic Complexes

“…2,2′:6′,2″-terpyridine ( tpy ) and its derivatives are important chelating ligands in coordination and supramolecular chemistry, yielding complexes with excellent electronic, optical and electrochemical properties [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Their coordination complexes, based on the cheap biocompatible and bioavailable Zn(II) metal center, were successfully used for obtaining polarized emissions [ 21 ] and emissive materials for optoelectronics and luminescence-based technologies [ 22 , 23 ], sensing and detection [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ], DNA binding and/or cleavage agents [ 34 , 35 , 36 , 37 ] and bioimaging [ 38 , 39 , 40 ].…”

“…luminescence-based technologies [22,23], sensing and detection [24][25][26][27][28][29][30][31][32][33], DNA binding and/or cleavage agents [34][35][36][37] and bioimaging [38][39][40].…”
