Abstract
Copper metalloenzymes ascorbate oxidase (AOase), amine oxidase (AmOase), and catechol oxidase (COase) possess copper(II) sites of coordination, which are trimeric, homodimeric, and dimeric, respectively. Two newly mononuclear copper(II) complexes, namely, [Cu(L)(bpy)](ClO4) (1) and [Cu(L)(phen)](ClO4) (2) where HL = Schiff base, have been synthesized. UV-visible, EPR and single-crystal X-ray diffraction examinations were used to validate the geometry in solution and solid state. For complex 1, the metal exhibits a coordination sphere between square pyramidal and trigonal bipyramidal geometry (τ, 0.49). A positive CuII/I redox potential indicates a stable switching between CuII and CuI redox states. Despite the monomeric origin, both homogeneous catalysts (1 or 2) in MeOH were found to favor three distinct chemical transformations, namely, ascorbic acid (H2A) to dehydroascorbic acid (DA), benzylamine (Ph-CH2-NH2) to benzaldehyde (Ph-CHO), and 3,5-di-tert-butylcatechol (3,5-DTBC) to 3,5-di-tert-butylquinone (3,5-DTBQ) [kcat: AOase, 9.6 (1) or 2.0 × 106 h-1(2); AmOase, 13.4 (1) or 9.4 × 106 h-1 (2); COase, 2.0 (1) or 1.9 × 103 h-1 (2)]. They exhibit higher levels of AOase activity as indicated by their kcat values compared to the AOase enzyme. The kcat values for COase activity in buffer solution [5.93 (1) or 2.95 × 105 h-1 (2)] are one order lower than those of the enzymes. This is because of the labile nature of the coordinated donor, the flexibility of the ligand, the simplicity of the catalyst-substrate interaction, and the positive CuII/I redox potential. Interestingly, more efficient catalysis is promoted by 1 and 2 concerning that of other mono- and dicopper(II) complexes.

Abstract
Three new molecular complexes (phen)3(2-amino-Bz)2(H+)(BF4-)·3H2O 5, (phen)3(2-amino-5(6)-methyl-Bz)2(H+)(BF4-)·H2O 6, and (phen)(1-methyl-2-amino-Bz)(H+)(BF4-) 7, were prepared by self-assembly of 1,10-phenanthroline (phen) and various substituted 2-aminobenzimidazoles. Confirmation of their structures was established through spectroscopic methods and elemental analysis. The X-ray diffraction analysis revealed that the crystal structure of 7 is stabilized by the formation of hydrogen bonds and short contacts. In addition, the molecular geometry and electron structure of molecules 5 and 6 were theoretically evaluated using density functional theory (DFT) methods. According to the DFT B3LYP/6-311+G* calculations, the protonated benzimidazole (Bz) units act as NH hydrogen bond donors, binding two phenanthrolines and a BF4- ion. Non-protonated Bz unit form hydrogen bonds with the N-atoms of a third molecule phen. The molecular assembly is held together by π-π stacking between benzimidazole and phenanthroline rings, allowing for N-atoms to associate with water molecules. The complexes were tested in vitro for their tumor cell growth inhibitory effects on prostate (PC3), breast (MDA-MB-231 and MCF-7), and cervical (HeLa) cancer cell lines using MTT-dye reduction assay. The in vitro cytotoxicity analysis and spectrophotometric investigation in the presence of ct-DNA, showed that self-assembled molecules 5-7 are promising DNA-binding anticancer agents warranting further in-depth exploration.

Abstract
The title compound, [Cu(C11H15N2O)(C12H8N2)]ClO4 or [Cu(L)(phen)](ClO4) {where L refers to the deprotonated form of 2-[(2-di-methyl-amino-ethyl-imino)-meth-yl]phenol} and phen is 1,10-phenanthroline) is a mononuclear mixed ligand copper(II) complex. The CuII atom is coordinated by two N and one O atoms of the tridentate Schiff base ligand (HL) and two N atoms of the 1,10-phenanthroline ligand, resulting in a five-coordinate complex. The asymmetric unit of the title complex contains two crystallographically independent complex cations (a and b) with a slightly different geometry around the CuII ion. The value of the trigonality index τ, indicates that in both cations a and b, the CuII atoms display a square-pyramidal distorted trigonal-bipyramidal (SPDTBP) geometry, although the distortion is greater for cation a.

Abstract
Two new mixed-ligand complexes with general formula [Cu(SB)(L')]ClO4 (1 and 2) were synthesized and characterized by different spectroscopic and analytical techniques including Fourier transform infrared (FT-IR) and UV-Vis spectroscopy and elemental analyses. The SB ligand is an unsymmetrical tridentate NN'O type Schiff base ligand that was derived from the condensation of 1,2-ethylenediamine and 5-bromo-2-hydroxy-3-nitrobenzaldehyde. The L' ligand is pyridine in (1) and 2,2'-dimethyl-4,4'-bithiazole (BTZ) in (2). Crystal structure of (2) was also obtained. The two complexes were used as anticancer agents against leukemia cancer cell line HL-60 and showed considerable anticancer activity. The anticancer activity of these complexes was comparable with the standard drug 5-fluorouracil (5-FU). Molecular docking and pharmacophore studies were also performed on DNA (PDB:1BNA) and leukemia inhibitor factor (LIF) (PDB:1EMR) to further investigate the anticancer and anti-COVID activity of these complexes. The molecular docking results against DNA revealed that (1) preferentially binds to the major groove of DNA receptor whereas (2) binds to the minor groove. Complex (2) performed better with 1EMR. The experimental and theoretical results showed good correlation. Molecular docking and pharmacophore studies were also applied to study the interactions between the synthesized complexes and SARS-CoV-2 virus receptor protein (PDB ID:6LU7). The results revealed that complex (2) had better interaction than (1), the free ligands (SB and BTZ), and the standard drug favipiravir.

Abstract
Multidentate copper metal complexes have been in the limelight in the area of DNA interaction studies exhibiting intercalation, groove binding and cross linking modes. Design of metal complex based on the versatile ligands decides their mode of DNA binding behavior. Based on this, a tetradentate Copper (II) complex, [Cu(L)(4,4'-bpy)], is synthesized using ONO hydrazone ligand and ancillary ligand, 4,4'-bipyridine. It is characterized by physico-chemical and UV-Visible, FTIR, Mass and EPR spectroscopic techniques. The binding pattern of the characterized complex with DNA has been assessed by UV absorption and fluorescence spectral titrations as well as viscosity studies and it has exhibited peculiar threading intercalation. The binding constant, Kb value of the synthesized complex was found to be (4.38 ± 0.09) × 104 M-1, greater than that of the hydrazone ligand (Kb = 2.29 × 104 M-1) and lesser than the classical intercalator ethidium bromide - EtBr (Kb = 107). The fluorescence quenching assays in the presence of ethidium bromide and viscometric studies show threading intercalative mode of binding of the complex to the DNA base pairs. Molecular docking studies further supports such a binding pattern with the bipyridine ring of the complex intercalating with deoxycytosine nucleobase of DNA. ADME (Absorption, Distribution, Metabolism and Excretion) parameters of the complex and ligand were predicted to get an idea of drug likeliness and to correlate the structural properties with semi DNA intercalative pattern of the same.

Abstract
Seven novel Copper(II) complexes, namely [Cu(Am4DHotaz)(H2O)2](ClO4) (1), [Cu(Am4DHotaz)(NO3)(MeOH)]·H2O (2), [Cu(Am4Motaz)2(H2O)](ClO4)2·0.83H2O (3), [Cu(Am4Motaz)2(NO3)]NO3·MeOH (4), [Cu(Am4Eotaz)2(NO3)]3(NO3)3·2H2O (5), [Cu(Am4Eotaz)2(ClO4)](ClO4) (6) and [Cu(Am4Eotaz)(ClO4)(H2O)](ClO4) (6a) (HAm4DHotaz = N'-(4-oxothiazolidin-2-ylidene)pyridine-2-carbohydrazonamide, Am4Motaz = N'-(3-methyl-4-oxothiazolidin-2-ylidene)pyridine-2-carbohydrazonamide and Am4Eotaz = N'-(3-ethyl-4-oxothiazolidin-2-ylidene)pyridine-2-carbohydrazonamide), have been successfully synthesized and characterized by several physicochemical techniques and, for 1-6 complexes, single crystal X-ray diffraction. Having the structural data as a base, complexes 1, 2 and 3 exhibited square pyramidal to square pyramidal slightly distorted geometry, whereas 4, 5 and 6 an intermediate between square pyramidal and trigonal bipyramidal. The ability of complexes 1-6 to cleave DNA was assayed with the aid of gel electrophoresis on supercoiled pUC18-DNA. Except for [Cu(Am4Motaz)2(H2O)](ClO4)2·0.83H2O (3), the compounds were not able to perform DNA cleavage (data not shown). Since 3 has been shown to behave as a nuclease, its interaction with DNA was studied by means of thermal denaturation and viscosimetry measurements.

Abstract
Abstract
Micellar solubilization and physicochemical behaviour of [Ni(phen)3]F2 EtOH · MeOH · 8 H2O complex in sodium 2-ethylhexyl sulfate and sodium bis(2-ethyl hexyl) sulfosuccinate is addressed in this paper. The interactions of surfactants in the solution of nickel complex were studied by UV-Vis spectroscopy and electrical conductivity. The extent of solubilization in terms of partitioning and binding parameters was determined by UV-Vis spectroscopy, whereas conductivity data were employed to calculate critical micellar concentration and other thermodynamic parameters of micellization. The value of critical micellar concentration increased in both surfactants due to structure breaking effect of nickel complex. The complex showed significant antioxidant radical scavenging and hemolytic activities, without any substantial cytotoxic activity against 3T3 cell line.

Abstract
The ligand quantity, ligand type, and coordination geometry have important influences on the anticancer activity of metal-based complexes. On the basis of the structures of previously reported 1:1 Cu(II)/ligand complexes ([Cu(L1)Cl]·2H2O 1a, [Cu(L2)Cl]·H2O 2a, and [Cu(L2)NO3]·H2O 3a), we subsequently designed, developed, and characterized a series of corresponding 1:1:1 Cu(II)/ligand/co-ligand complexes ([Cu(L1)(Py)Cl]·H2O 1b, [Cu(L2)(Py)Cl] 2b, and [Cu(L2)(Py)NO3] 3b), where L1 = (E)-N'-(2-hydroxybenzylidene)acetohydrazide, L2 = (E)-N'-(2- hydroxybenzylidene)benzohydrazide, and Py = pyridine. All six Cu(II) complexes were assessed for their in vitro anticancer properties against a panel of human cancer cells, including cisplatin-resistant A549cisR cell lines. Interestingly, we observed that the 1:1:1 Cu/ligand/co-ligand mixed-ligand Cu(II) complexes exhibited higher anticancer activity than the corresponding 1:1 Cu(II)/ligand complexes. In particular, the 1:1:1 Cu(II)/ligand/co-ligand complex 3b displayed the greatest toxicity toward several cancer cells with better IC50 (1.12-3.77 μM) than cisplatin. Further mechanistic explorations showed that the 3b complex induced DNA damage, thus resulting in mitochondria-mediated apoptotic cell death. Furthermore, the 3b complex displayed pronounced cytostatic effects in the MCF-7 3D spheroid model.

Abstract
In this study, two Ni(II) complexes, namely [Ni(HL1)2(OAc)2] (1) and [Ni(L2)2] (2) (where HL1 and HL2 are (E)-1-((1-(2-hydroxyethyl)-1H-pyrazol-5-ylimino)methyl)-naphthalen-2-ol) and (E)-ethyl-5-((2-hydroxynaphthalen-1-yl)methyleneamino)-1-methyl-1H-pyrazole-4-carboxylate, respectively), were synthesized and characterized by X-ray crystallography, Electrospray Ionization Mass Spectrometry (ESI-MS), elemental analysis, and IR. Their uptake in biological macromolecules and cancer cells were preliminarily investigated through electronic absorption (UV-Vis), circular dichroism (CD) and fluorescence quenching measurements. Bovine serum albumin (BSA) interaction experiments were investigated by spectroscopy which showed that the complexes and ligands could quench the intrinsic fluorescence of BSA through an obvious static quenching process. The spectroscopic studies indicated that these complexes could bind to DNA via groove, non-covalent, and electrostatic interactions. Furthermore, in vitro methyl thiazolyl tetrazolium (MTT) assays and Annexin V/PI flow cytometry experiments were performed to assess the antitumor capacity of the complexes against eight cell lines. The results show that both of the complexes possess reasonable cytotoxicities.
