“…It is possible that A BPs stabilises the V(III) oxidation state and with VCl 3 forms weak monomeric and dimeric complexes in the 1.8-4.5 pH range, depending on the concentration of V (Bukietynska and Krot-Lacina 2001). VO(II) binds to DNA through G and A N-7 atoms and via the backbone PO 2 moieties.…”

Various human activities lead to the pollution of ground, drinking, and wastewater with toxic metals. It is well known that metal ions preferentially bind to DNA phosphate backbones or DNA nucleobases, or both. Foreman et al. (Environ Toxicol Chem 30(8):1810-1818, 2011) reported the use of a DNA-dye based assay suitable for use as a toxicity test for potable environmental water. They compared the results of this test with the responses of live-organism bioassays. The DNA-based demonstrated that the loss of SYBR Green I fluorescence dye bound to calf thymus DNA was proportional to the toxicity of the water sample. However, this report raised questions about the mechanism that formed the basis of this quasi-quantitatively test. In this review, we identify the unique and preferred DNA-binding sites of individual metals. We show how highly sensitive and selective DNA-based sensors can be designed that contain multiple binding sites for 21 heavy metal cations that bind to DNA and change its structure, consistent with the release of the DNA-bound dye.

“…At higher pH levels (> 4.5), the dimeric and/or polymeric compound, {H 2 [VCl 2 (Ad Ϫ )O]} n , was isolated. 19 The stoichiometry, stability and modes of co-ordination have been studied, by spectroscopic methods, for vanadyl complexes of -asparagine and -glutamine. 20 The two series of octahedral oxovanadium() complexes containing the tetradentate amidate ligands Hcapca 1 and H 2 capcah 2, trans-[VOX(capca)] 0/ϩ (X = Cl, SCN, N 3 , OAc, PhCOO, Im, Bu n NH 2 ) and cis-[VOX(Hcapcah)] 0/ϩ (X = Cl, SCN,N 3 , Im), have been prepared and characterised, including by X-ray crystallographic and EPR techniques.…”

“…Reactions of the fluorine donors SnF 2 and SbF 3 with NbCl 5 in MeCN and dmso have afforded anionic and neutral products respectively. The reactions were monitored by 19 F, 93 Nb, and 119 Sn NMR spectrometry. 30 Similar reactions of SnF 2 and SbF 3 with TaX 5 (X = F, Cl) in MeCN and dmso have also been studied by both 19 F and 119 Sn NMR.…”

“…At present, the reaction mechanism and how metal ions such as Cu(II), Mg(II), Ca(II), V(II), V(III), Zn(II), Ag(I) bind to adenine had been investigated by UV-visible spectroscopy, infrared spectroscopy, Raman spectroscopy, electronic spectroscopy, NMR, X-ray diffraction, high performance liquid chromatography (HPLC) and some electrochemical methods [20][21][22][23][24][25][26][27]. So, based on previous works, a novel method for the detection of adenine had been developed by fluorescence spectrophotometry.…”
