Interaction with CT-DNA and in vitro cytotoxicity of two new copper(II)-based potential drugs derived from octanoic hydrazide ligands. J Inorg Biochem 2024; 256:112546. [PMID: 38593611 DOI: 10.1016/j.jinorgbio.2024.112546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 03/13/2024] [Accepted: 03/27/2024] [Indexed: 04/11/2024]
Abstract
Two copper(II) complexes [Cu(Hpmoh)(NO3)(NCS)] (1) and [Cu(peoh)(N3)]2 (2) were designed and synthesized by reaction of Cu(NO3)2·3H2O with hydrazone Schiff base ligands,abbreviated with Hpmoh and Hpeoh. Hpmoh and Hpeoh were prepared by condensation reaction of octanoic hydrazide with pyridine-2-carboxyaldehyde and 2-acetylpyridine, respectively. Complexes 1 and 2 were characterized using different analytical techniques such as FT-IR, UV-Vis, IR, EPR and single X-ray diffraction (XRD) analyses as well as computational methods (DFT). The XRD of 1 and 2 shows a mononuclear or a dinuclear structure with the copper(II) centre adopting a slightly distorted square pyramidal geometry. In water-containing solution and in DMSO, 1 and 2 undergo a partial transformation with formation of [Cu(Hpmoh)(NO3)(NCS)] (1) and [Cu(Hpmoh)(NO3)(H2O/DMSO)] (1a) in one system and [Cu(peoh)(N3)] (2a) in the other one, as supported by DFT calculations. Docking simulations confirmed that the intercalation is the preferred binding mode with DNA for 1, 1a and 2a, but suggested that the minor groove binding is also possible. A significant fluorescence quenching of the DNA-ethidium bromide conjugate was observed upon the addition of complexes 1 and 2 with a quenching constant around 104 M-1 s-1. Finally, both 1 and 2 were examined for anti-cancer activity using MDA-MB-231 (human breast adenocarcinoma) and A375 (malignant melanoma) cell lines through in vitro MTT assay which suggest comparable cancer cell killing efficacy, with the higher effectiveness of 2 due to the dissociation into two [Cu(peoh)(N3)] units.

Abstract
The intercalative yeast t-RNA binding behavior of some metallo-surfactant complexes, Co(ip)2(TA)2](ClO4)3 (1) and [Co(dpq)2(TA)2](ClO4)3 (2) where TA = Tetradecylamine (Myristylamine), ip = imidazo[4,5-f][1,10]phenanthroline and dpq = dipyrido[3,2-d:2'-3'-f]quinoxaline containing π-conjugated systems (both below and above critical micelle concentration) have been investigated by means of absorption spectral titration, competitive binding, circular dichroism, cyclic voltammetry, and viscometry measurements. Absorption spectral titration results implicate yeast tRNA has significant effects on the binding behaviors of two surfactant complexes via intercalative mode showed a significant absorption band of hypochromicity with red shift. The intrinsic binding constant values below and above CMC were determined as Kb = 6.12 × 105 M-1, 2.31 × 106 M-1, for complex (1) and 7.23 × 105 M-1, 3.57 × 106 M-1, for complex (2). In both sets of complexes (1) and (2), the complexes bind more strongly to yeast tRNA in the above critical micelle concentration can be hydrophobic and confirm intercalation. Competitive displacement studies confirmed that complexes bind to yeast tRNA via intercalative mode. Cyclic voltammetry studies suggest the increasing amounts of yeast tRNA, the cathodic potential Epc for the two complexes shows a positive shift in peak potential indicated the process of binding via intercalation. These observations were further validated by CD, and hydrodynamic measurements. All these studies suggesting that a surfactant complex binds to yeast tRNA appear to be mainly intercalative because of hydrophobicity due to extending aromaticity of the π system of the ligand and planarity of the complex has a significant effect on tRNA binding affinity increasing in the order of complexes containing ligands ip < dpq.Communicated by Ramaswamy H.

Abstract
Cyanide is a very toxic pollutant to aquatic life and the environment. Analytical methods for the quantitative assay of cyanide, which are rapid, sensitive (low limit of detection), and cost-effective, are in great demand. Colorimetric and fluorometric methods are ideally suited for this purpose. In this report, we describe a Ni(II) complex containing a pyridoxal platform for the rapid and sensitive fluorometric estimation of cyanide. The square-planar Ni(II) complex, [Ni(L)(N3)]·3H2O, where the ligand LH = 4-[(2-dimethylamino-ethylimino)-methyl]-5-hydroxymtheyl-2-methyl-pyridin-3-ol, a Schiff base formed between pyridoxal and (2-dimethylamino)ethyl amine, was synthesized and characterized by various spectroscopic techniques as well as by single-crystal X-ray structure determination. The complex was found to selectively bind CN- in the presence of other biologically important anions such as F-, Cl-, Br-, I-, OAc-, S2-, NO3 -, PO4 3-, SO4 2-, and H2PO4 - in tris-HCl/NaCl buffer [pH = 7.4], and it can be monitored by fluorescence turn-on or by UV-visible spectroscopy. The binding constant of the complex with CN- was estimated to be 2.046 × 1014 M-2 and the limit of detection (LOD) was 9 nM, the LOD being considerably lower than the maximum permissible level of cyanide ions (1.9 μM) in drinking water, as recognized by the World Health Organization (WHO). The effects of pH and temperature on the sensing are also investigated. The Ni(II) complex is also found to bind to calf-thymus DNA very strongly, and the apparent binding constant (K app) was determined to be 1.33 × 107 M-1 by the fluorescence quenching of the ethidium bromide-DNA adduct by the complex.

Abstract
Five novel nickel(II) complexes with the non-steroidal anti-inflammatory drug sodium meclofenamate (Na-mclf) have been synthesized and characterized in the absence or co-existence of the nitrogen-donors imidazole (Himi), 2,2'-bipyridylamine (bipyam), 2,2'-bipyridylketoxime (Hpko) and 2,9-dimethyl-1,10-phenanthroline (neoc); namely [Ni(mclf-O)2(Himi)2(MeOH)2], [Ni(mclf-O)2(MeOH)4], [Ni(mclf-O)(mclf-O,O')(bipyam)(MeOH)]·0.25MeOH, [Ni(mclf-O,O')2(neoc)] and [Ni(mclf-O)2(Hpko-N,N')2]·MeOH·0.5H2O. The affinity of the complexes for calf-thymus (CT) DNA was investigated by various techniques and intercalation is suggested as the most possible interaction mode. The interaction of the complexes for bovine and human serum albumins was also investigated in order to determine the binding constants, concluding that the complexes bind reversibly to albumins for the transportation towards their target cells or tissues and their release upon arrival at biotargets. The antioxidant activity of the compounds was evaluated via their ability to scavenge 1,1-diphenyl-picrylhydrazyl and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) free radicals and to reduce H2O2. For the determination of the anticholinergic ability of the complexes the in vitro inhibitory activity against the enzymes acetylcholinesterase and butyrylcholinesterase was evaluated and presented promising results. The in silico molecular modeling calculations employed provide useful insights for the understanding of the mechanism of action of the studied complexes at a molecular level. This applies on both the impairment of DNA by its binding with the studied complexes and transportation through serum albumins, as well as the ability of these compounds to act as anticholinergic agents.

Abstract
The interaction of copper(II) with the non-steroidal anti-inflammatory drug sodium meclofenamate (Na-mclf) in the presence or absence of the nitrogen-donor co-ligands pyridine (py) or 2,2'-bipyridylamine (bipyam), yielded the novel Cu(II) complexes [Cu2(mclf-O,O')4(MeOH)2]·2MeOH (1·2MeOH), [Cu(mclf-O)2(py)3]·H2O·0.5MeOH (2·H2O·0.5MeOH) and [Cu(mclf-O,O')2(bipyam)] (3). The characterization of the complexes was achieved by various techniques, including single-crystal X-ray crystallography. In order to study the binding mode and strength of the complexes to calf-thymus (CT) DNA, various techniques were employed which suggested intercalation between the DNA-bases as the most possible interaction mode. Competitive studies with ethidium bromide (EB) revealed the ability of the complexes to displace the EB from the EB-DNA adduct, verifying the intercalative binding mode. The affinity of the complexes to bovine and human serum albumin proteins (SAs) was investigated by fluorescence emission spectroscopy and the corresponding binding constants bear relatively high values, showing that the complexes bind tightly and possibly reversibly to SAs. The antioxidant activity of the complexes against 1,1-diphenyl-picrylhydrazyl (DPPH), 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals and the ability to reduce H2O2 proved to be of significant magnitude. The in vitro inhibitory activity against the enzymes acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) was evaluated, in order to assess the anticholinergic ability of the complexes, which appeared promising.

Abstract
The interaction between Tb(IV)-NR complex and herring sperm DNA in buffer solution of Tris-HCl was investigated with the use of acridine orange(AO) as a spectral probe. The binding modes and other information were provided by the UV-spectrophotometry and fluorescence spectroscopy. The thermodynamic functions expressed that the binding constants of Tb(IV)-NR complex with DNA was Kθ298.15K = 4.03 × 105 L·mol-1, Kθ310.15K =1.30 × 107 L·mol-1, and the ΔrGθ m 298.15 K=-3.20 × 104 J·mol-1. The scatchard equation suggested that the interaction mode between Tb(IV)-NR complex and herring sperm DNA is electrostatic and weak intercalation bindings. FTIR spectroscopy results also indicate that there is a specific interaction between the Tb(IV)-NR complex and the A and G bases of DNA.

Abstract
To assess the potential cytostatic properties of the thulium(III)-arsenazo III complex as a probe of rare earth complex antitumor drugs, the interaction information of the thulium(III)-arsenazo III complex with DNA was obtained by using spectroscopy, viscosity measurements, and voltammetric methods. The thermodynamic functions demonstrated that the binding constants of the thulium(III)-arsenazo III complex with DNA were Kθ298.15K = 4.84 × 106 L·mol−1 and Kθ308.15K = 4.48 × 106 L·mol−1, and the binding process was enthalpy driven. The increase in relative viscosity of DNA with the addition of the thulium(III)-arsenazo III complex and the results from Scatchard and voltammetric methods showed that the interaction mode between the thulium(III)-arsenazo III complex and DNA was groove binding along with weak intercalative binding.

Abstract
A new trinickel(II) complex bridged by N-[3-(dimethylamino)propyl]- N'-(2-hydroxylphenyl)oxamido (H3 pdmapo), namely [Ni3 (pdmapo)2 (H2 O)2 ]⋅4CH3 OH, was synthesized and characterized by X-ray single-crystal diffraction and other methods. In the molecule, two symmetric cis-pdmapo3- mononickel(II) complexes as a "complex ligand" using the carbonyl oxygen atoms coordinate to the center nickel(II) ion situated on an inversion point. The Ni···Ni distance through the oxamido bridge is 5.2624(4) Å. The center nickel(II) ion and the lateral ones have octahedral and square-planar coordination geometries, respectively. In the crystal, a three-dimensional supramolecular network dominated by hydrogen bonds is observed. The reactivity toward DNA/protein bovine serum albumin (BSA) revealed that the complex could interact with herring sperm DNA (HS-DNA) through the intercalation mode and quench the intrinsic fluorescence of BSA via a static mechanism. The in vitro anticancer activities suggested that the complex is active against the selected tumor cell lines.

Abstract
The interaction of the Trp-Sm(III) complex with herring sperm DNA (hs-DNA) was investigated with the use of acridine orange (AO) dye as a spectral probe for UV-vis spectrophotometry and fluorescence spectroscopy. The results showed that the both the Trp-Sm(III) complex and the AO molecule could intercalate into the double helix of the DNA. The Sm(III)-(Trp)3 complex was stabilized by intercalation into the DNA with binding constants: K(Ө)25°C = 7.14 × 10(5) L·mol(-1) and K(Ө) 37°C = 5.28 × 10(4) L·mol(-1), and it could displace the AO dye from the AO-DNA complex in a competitive reaction. Computation of the thermodynamic functions demonstrates that Δr Hm (Ө) is the primary driving power of the interaction between the Sm(III)(Trp)3 complex and the DNA. The results from Scatchard and viscometry methods suggested that the interaction mode between the Sm(III)(Trp)3 complex and the hs-DNA is groove binding and weak intercalation binding.

Abstract
AbstractA novel, sensitive and selective electrochemical hybridisation biosensor was developed for the detection of the hepatitis B virus (HBV) using a manganese(II) complex as electrochemical indicator and a DNA probe-modified carbon paste electrode as the biosensor (DNA/CPE). The results showed that this complex could be accumulated electrochemically the immobilised dsDNA layer rather than in the single-stranded DNA (ssDNA) layer. On the basis of this, the manganese complex was used as an electrochemical hybridisation indicator for the detection of oligonucleotides related to HBV. The hybridisation event was evaluated on the basis of the difference between the reduction signals of the manganese(II) complex with the probe DNA prior to and post hybridisation with a target sequence using a differential pulse mode. Several factors affecting the immobilisation and hybridisation of oligonucleotides as well as the indicator’s accumulation were investigated. Experiments with a noncomplementary and mismatch sequences demonstrated the good selectivity of the biosensor. Using this approach, the HBV target oligonucleotide’s sequence could be quantified over arange from 0.22 ng L

Abstract
The syntheses, structures and spectroscopic properties of Cu(II) and Zn(II) complexes having Knoevenagel condensate β-diketimine Schiff base ligands have been investigated in this paper. Characterization of these complexes was carried out using FTIR, NMR, UV-Vis, elemental analysis, mass and EPR techniques. Absorption titration, electrochemical analyses and viscosity measurements have also been carried out to determine the mode of binding. The shift in ΔEp, E1/2 and Ipc values explores the interaction of CT DNA with the above metal complexes. Interaction of ligands and their complexes with DNA revealed an intercalative mode of binding between them. Antimicrobial studies showed an effective antimicrobial activity of the metal ions after coordination with the ligands. The antioxidant properties of the Schiff base ligands and their complexes were evaluated in a series of in vitro tests by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and H2O2 free radical scavengers. In vivo and in vitro antitumor functions of the complexes against Ehrlich ascites carcinoma tumor model have also been investigated. All the results support that β-diketone derived Knoevenagel condensate Schiff base complexes may act as novel antitumor drugs and suggest that their potent cell life inhibition may contribute to their anti-cancer efficacy.

Abstract
Three novel copper(II) complexes with the second-generation quinolone antibacterial agents norfloxacin (nfH) and ofloxacin (ofloH) have been synthesized resulting in the complexes [Cu(nfH)(phen)Cl]Cl·5H(2)O (1·5H(2)O), [Cu(nfH)(2)]Cl(2)·6H(2)O (2·6H(2)O) and [Cu(II)(ofloH)(2)][(Cu(I)Cl(2))(2)] (3), respectively. The crystal structures of the complexes have been determined by X-ray crystallography revealing that the quinolones act as bidentate ligands coordinated to Cu(II) atom through the pyridone oxygen and a carboxylato oxygen. UV study of the interaction of the quinolones and the complexes with calf-thymus DNA (CT DNA) has shown that they can bind to CT DNA with [Cu(II)(ofloxacin)(2)][(Cu(I)Cl(2))(2)] exhibiting the highest binding constant to CT DNA. The cyclic voltammograms of the complexes in the presence of CT DNA solution have shown that the interaction of the complexes with CT DNA is mainly through electrostatic binding. DNA solution viscosity measurements have shown that the interaction of the compounds with CT DNA by classical intercalation may be ruled out. Competitive studies with ethidium bromide (EB) indicate that the complexes can partially displace the DNA-bound EB suggesting low to moderate competition with EB. Norfloxacin, ofloxacin and their copper complexes exhibit good binding propensity to human or bovine serum albumin protein having relatively high binding constant values.

Abstract
Complexes of trimethoprim (TMP), with Cu(II), Zn(II), Pt(II), Ru(III) and Fe(III) have been synthesized. Then, these complexes have been characterized by spectroscopic techniques involving UV-vis, IR, mass and (1)H NMR. CHN elemental analysis, electrochemical and thermal behavior of complexes have also been investigated. The electrochemical properties of all complexes have been investigated by cyclic voltammetry (CV) using glassy carbon electrode. The biological activity of the complexes has been evaluated by examining their ability to bind to calf-thymus DNA (CT DNA) with UV spectroscopy and cyclic voltammetry. UV studies of the interaction of the complexes with DNA have shown that these compounds can bind to CT DNA. The binding constants of the complexes with CT DNA have also been calculated. The cyclic voltammograms of the complexes in the presence of CT DNA have shown that the complexes can bind to CT DNA by both the intercalative and the electrostatic binding mode. The antimicrobial activity of these complexes has been evaluated against three Gram-positive and four Gram-negative bacteria. Antifungal activity against two different fungi has been evaluated and compared with the reference drug TMP. Almost all types of complexes show excellent activity against all type of bacteria and fungi. The morphology of the CT DNA, TMP, metal ions and metal complexes has been investigated by scanning electron microscopy (SEM). To get the SEM images, the interaction of compounds with CT DNA has been studied by means of differential pulse voltammetry (DPV) at CT DNA modified pencil graphite electrode (PGE). The decrease in intensity of the guanine oxidation signals has been used as an indicator for the interaction mechanism.

Abstract
By means of ultraviolet-visible (UV-Vis) and fluorescence spectra, the binding ratio between vitamin K(3) and herring-sperm DNA in a physiological pH environment (pH = 7.40) was determined as n(K3):n(DNA) = 2:1, and the binding constants of vitamin K(3) binding to DNA at different temperatures were determined as K(θ)(298K) = 1.28 × 10(5) L·mol(-1) and K(θ)(310K) = 7.19 × 10(4) L·mol(-1), which were confirmed using the double reciprocal method are Δ(r)H(m)(θ) = -3.57 × 10(4) J·mol(-1), Δ(r)G(m)(θ) = -2.92 × 10(4) J·mol(-1), and Δ(r)S(m)(θ) = 217.67 J·mol(-1)K(-1). The driving power of this process was enthalpy. An intercalation binding of the vitamin K(3) with DNA was supported by a competitive experiment using acridine orange (AO) as a spectral probe. By combination analysis of the Scatchard method and cyclic voltammetry, we suggested that the interaction mode between vitamin K(3) and herring-sperm DNA would be a mixed mode. The quinonoid, duality fused-ring of vitamin K(3) can intercalate into the base pairs of DNA, and there is an electrostatic binding along with intercalation binding.

Abstract
Copper(II) complexes with the non-steroidal anti-inflammatory drugs (NSAIDs) naproxen and diclofenac have been synthesized and characterized in the presence of nitrogen donor heterocyclic ligands (2,2'-bipyridine, 1,10-phenanthroline or pyridine). Naproxen and diclofenac act as deprotonated ligands coordinated to Cu(II) ion through carboxylato oxygens. The crystal structures of (2,2'-bipyridine)bis(naproxenato)copper(II), 1, (1,10-phenanthroline)bis(naproxenato)copper(II), 2 and bis(pyridine)bis(diclofenac)copper(II), 4 have been determined by X-ray crystallography. The UV study of the interaction of the complexes with calf-thymus DNA (CT DNA) has shown that the complexes can bind to CT DNA with (2,2'-bipyridine)bis(naproxenato)copper(II) exhibiting the highest binding constant to CT DNA. Competitive study with ethidium bromide (EB) indicates that the complexes can displace the DNA-bound EB suggesting strong competition with EB. The cyclic voltammograms of the complexes recorded in the presence of CT DNA have shown that the complexes can bind to CT DNA by the intercalative binding mode which has also been verified by DNA solution viscosity measurements. The NSAID ligands and their complexes exhibit good binding propensity to human or bovine serum albumin protein having relatively high binding constant values. The biological properties of the previously reported complexes [Cu(2)(naproxenato)(4)(H(2)O)(2)], [Cu(2)(diclofenac)(4)(H(2)O)(2)] and [Cu(naproxenato)(2)(pyridine)(2)(H(2)O)] have been also evaluated. The dinuclear complexes exhibit similar affinity for CT DNA as the 2,2'-bipyridine or 1,10-phenanthroline containing complexes. The pyridine containing complexes exhibit the lowest affinity for CT DNA and the lowest ability to displace EB from its EB-DNA complex.

Abstract
By means of UV and fluorescence spectra, the binding ratios between Er(III)-Trp and DNA in physiological pH environment (pH 7.40) were determined as n(Trp):n(Er(III))=3:1 and (n)ER(III)(Trp)(3):(n)(DNA) = 2:1, and the apparent molar absorptivity of epsilon(Er(III)-Trp-DNA) is 4.33 x 10(5) L mol(-1)cm(-1) which was confirmed by molar ratio method. The binding constants at different temperatures K(B25 degrees C)(theta)=1.93 x 10(4)L mol(-1) and K(B37 degrees C)(theta)=5.28 x 10(3)L mol(-1) were obtained by double reciprocal method. Thermodynamic function computation demonstrates that Delta(r)H(m)(theta) is the primary driving power of the interaction between Er(III)(Trp)(3) and DNA. By combination analysis of the Scatchard method and CD spectrometry, we suggested that the interaction mode between Er(III)(Trp)(3) complex and herring sperm DNA is groove and intercalation bindings.

Abstract
The interaction of the Schiff base (K[HL]) with herring sperm DNA was studied by UV-vis absorption, fluorescence and viscosity methods in a physiological pH environment (pH 7.40), where the Schiff base was derived from vanillin and L-tryptophan. A binding ratio of nK[HL]:nDNA = 5:1 and an apparent molar absorption coefficient of ?K[HL]-DNA = 4.98 ? 105 L?mol-1?cm-1 were confirmed by the mole ratio method. The binding constants of KB ? 28?C = 1.94 ? 105 L?mol-1 and KB ? 37?C = 1.09 ? 105 L?mol-1 were obtained by the double reciprocal method. Thermodynamic parameters suggest that the interaction between K[HL] and DNA is driven mainly by enthalpy. Combined with Scatchard methods and viscosity methods, the results indicate the presence of intercalation and groove binding between K[HL] and DNA.

Abstract
The mononuclear nickel(II) complexes with the third-generation quinolone antibacterial agent sparfloxacin in the absence or presence of nitrogen donor heterocyclic ligands (1,10-phenanthroline or 2,2'-bipyridine) have been synthesized and characterized. The experimental data suggest that sparfloxacin acts as deprotonated bidentate ligand coordinated to Ni(II) ion through the ketone and carboxylato oxygens. The crystal structure of (1,10-phenanthroline)bis(sparfloxacinato) nickel(II), 2 has been determined by X-ray crystallography. The cyclic voltammograms of the complexes recorded in dmso solution and in 1/2 dmso/buffer (containing 150 mM NaCl and 15 mM trisodium citrate at pH 7.0) solution have shown that in the presence of CT DNA they can bind to CT DNA by the intercalative binding mode. UV study of the interaction of the complexes with calf-thymus DNA (CT DNA) has shown that the complexes can bind to CT DNA and 2 exhibits the highest binding constant to CT DNA. Competitive study with ethidium bromide (EB) has shown that the complexes can displace the DNA-bound EB indicating that they bind to DNA in strong competition with EB for the intercalative binding site. The antimicrobial activity of the complexes has been tested on three different microorganisms and has revealed that the inhibition provided by the complexes is slightly decreased in comparison to free sparfloxacin. The complexes exhibit good binding propensity to human and bovine serum albumin proteins having relatively high binding constant values.
