Abstract
A novel hydrazone ligand (o-H2BMP) N-(benzo[d]thiazol-2-yl)-3-oxo-3-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)propanamide alongside its Cu(II), Cd(II), and VO(II) complexes were prepared and structurally characterized via various spectroscopic analyses (Fourier transform infrared spectroscopy, UV-visible spectroscopy, 1H/13C NMR spectroscopy, liquid chromatography coupled to mass spectrometry, and electron paramagnetic resonance spectroscopy) as well as by elemental analysis, thermal gravimetry analysis/differential thermal analysis, and magnetic moment measurements. Powder X-ray diffraction analysis was also performed for the free ligand and its metal complexes to determine the crystallographic structures and atomic spacing. It also provided information on unit cell dimensions and the average crystallite size. Furthermore, geometric optimization and computational studies were carried out by applying Gaussian (09) software based on density-functional theory coupled with the B3LYP functional and LANL2DZ/6-31+G(d,p) mixed basis set to evaluate some distinct features such as molecular electrostatic potential, E HOMO, and E LUMO. Moreover, electrochemical measurements were performed for Cu(II) in the absence/presence of the chelating agent to predict the effect of complexation interaction in the solution state study. As part of the biological examination, antioxidant and antimicrobial assays were conducted for each compound individually, in addition to cytotoxicity evaluations via MTT assays for all isolated complexes compared to the corresponding metal salts. The MOE (molecular operating environment) approach was also applied to model the interface between the isolated compounds and proteins that were expressed in breast cancer at the atomic level.

Abstract
This work is devoted to the investigation of heterobimetallic Ru(II) complexes as photosensitizers for room-temperature photoactivated In2O3-based gas sensors. Nanocrystalline In2O3 was synthesized by the chemical precipitation method. The obtained In2O3 matrix has a single-phase bixbyite structure with an average grain size of 13–14 nm and a specific surface area of 72 ± 3 m2/g. The synthesis of new ditope ligands with different coordination centers, their ruthenium complexes, and the preparation of heterobimetallic complexes with various cations of heavy and transition metals (Ag+, Pb2+, or Cu2+) is reported. The heterobimetallic Ru(II) complexes were deposited onto the surface of the In2O3 matrix by impregnation. The obtained hybrid materials were characterized by X-ray fluorescent analysis, FTIR spectroscopy, and optical absorption spectroscopy. The elemental distribution on the hybrids was characterized by energy-dispersive X-ray spectroscopy (EDS) mapping. The gas sensor properties were investigated toward NO2, NO, and NH3 at room temperature under periodic blue LED irradiation. It was identified that the nature of the second binding cation in Ru(II) heterobimetallic complexes can influence the selectivity toward different gases. Thus, the maximum sensor signal for oxidizing gases (NO2, NO) was obtained for hybrids containing Ag+ or Pb2+ cations while the presence of Cu2+ cation results in the highest and reversible sensor response toward ammonia. This may be due to the specific adsorption of NH3 molecules on Cu2+ cations. On the other hand, Cu2+ ions are proposed to be active sites for the reduction of nitrogen oxides to N2. This fact leads to a significant decrease in the sensor response toward NO2 and NO gases.

Abstract
![]()
Coordination compounds
of earth-abundant 3d transition metals are
among the most effective catalysts for the electrochemical reduction
of carbon dioxide (CO2). While the properties of the metal
center are crucial for the ability of the complexes to electrochemically
activate CO2, systematic variations of the metal within
an identical, redox-innocent ligand backbone remain insufficiently
investigated. Here, we report on the synthesis, structural and spectroscopic
characterization, and electrochemical investigation of a series of
3d transition-metal complexes [M = Mn(I), Fe(II), Co(II), Ni(II),
Cu(I), and Zn(II)] coordinated by a new redox-innocent PNP pincer
ligand system. Only the Fe, Co, and Ni complexes reveal distinct metal-centered
electrochemical reductions from M(II) down to M(0) and show indications
for interaction with CO2 in their reduced states. The Ni(0)
d10 species associates with CO2 to form a putative
Aresta-type Ni-η2-CO2 complex, where electron
transfer to CO2 through back-bonding is insufficient to
enable electrocatalytic activity. By contrast, the Co(0) d9 intermediate binding CO2 can undergo additional electron
uptake into a formal cobalt(I) metallacarboxylate complex able to
promote turnover. Our data, together with the few literature precedents,
single out that an unsaturated coordination sphere (coordination number
= 4 or 5) and a d7-to-d9 configuration in the
reduced low oxidation state (+I or 0) are characteristics that foster
electrochemical CO2 activation for complexes based on redox-innocent
ligands. A series of 3d transition-metal complexes
(M = Mn, Fe, Co,
Ni, Cu, and Zn) coordinated by a new redox-innocent PNP pincer ligand
system were synthesized and structurally as well as electrochemically
analyzed to illuminate the role of the metal center in molecular electrochemical
carbon dioxide (CO2) activation.

Abstract

Three new thiosemicarbazones
(TSCs) HL1–HL3 as triapine
analogues bearing a redox-active phenolic moiety at the terminal nitrogen
atom were prepared. Reactions of HL1–HL3 with CuCl2·2H2O in anoxic methanol afforded three copper(II)
complexes, namely, Cu(HL1)Cl2 (1), [Cu(L2)Cl] (2′), and Cu(HL3)Cl2 (3), in good yields. Solution
speciation studies revealed that the metal-free ligands are stable
as HL1–HL3 at pH 7.4, while being air-sensitive in
the basic pH range. In dimethyl sulfoxide they exist as a mixture
of E and Z isomers. A mechanism
of the E/Z isomerization with an inversion at the
nitrogen atom of the Schiff base imine bond is proposed. The monocationic
complexes [Cu(L1–3)]+ are the most abundant
species in aqueous solutions at pH 7.4. Electrochemical and spectroelectrochemical
studies of 1, 2′, and 3 confirmed their redox activity in both the cathodic and the anodic
region of potentials. The one-electron reduction was identified as
metal-centered by electron paramagnetic resonance spectroelectrochemistry.
An electrochemical oxidation pointed out the ligand-centered oxidation,
while chemical oxidations of HL1 and HL2 as well as 1 and 2′ afforded several two-electron and four-electron
oxidation products, which were isolated and comprehensively characterized.
Complexes 1 and 2′ showed an antiproliferative
activity in Colo205 and Colo320 cancer cell lines with half-maximal
inhibitory concentration values in the low micromolar concentration
range, while 3 with the most closely related ligand to
triapine displayed the best selectivity for cancer cells versus normal
fibroblast cells (MRC-5). HL1 and 1 in the presence of 1,4-dithiothreitol are as
potent inhibitors of mR2 ribonucleotide reductase as triapine. Three triapine analogues HL1−HL3 bearing a
phenolic redox-active moiety showed moderate antiproliferative activity,
while one of the oxidation products HL2c′·CH3COOH revealed
high cytotoxicity in Colo205 and Colo320 cancer cell lines. Coordination
of HL1−HL3 to copper(II) increased strongly the cytotoxicity,
with complex 2′ showing IC50 values
of 0.181 and 0.159, respectively. The highest cytotoxicity of 2′ is likely due to the highest thermodynamic stability,
more negative reduction potential, and the lowest rate of reduction
by GSH.

Abstract
Copper phosphate nanoflowers (CuPNFs) have been synthesized in the presence of different aromatic phenanthroline derivatives (Ln), leading to inorganic-organic hybrid materials (Ln-CuPNFs). Studies revealed that the morphology of nanoflowers varies as a function of the aromatic moiety present in the derivative, Ln (where 'n' corresponds to phenyl, naphthyl, anthracenyl, and pyrenyl) used for coating the nanomaterial. Other noticeable changes were the increase in the size of the flower by ∼2-3 fold in the presence of these derivatives. In the absence of such aromatic phenanthroline derivatives, i.e., the use of 1,10-phenanthroline-5-amine did not induce the formation of nanoflowers, suggesting that the organic derivatization used in the present study stabilizes the nanoflower structure. Nanoflowers were characterized using X-ray diffraction, Brunauer-Emmett-Teller (BET) isotherm, X-ray photoelectron spectroscopy, Raman and Infrared spectroscopy, scanning electron microscopy, and transmission electron microscopy, thus covering a range of diffraction, spectroscopy, and microscopy techniques. Nanoflowers, Ln-CuPNFs, have been demonstrated for the oxidative reactions mimicking copper metalloenzymes in the presence and absence of hydrogen peroxide using different substrates. Thus, hybrid Ln-CuPNFs mediate the complete oxidation of o-phenylenediamine, dopamine, ascorbate oxidase, and terephthalic acid without causing much change in the morphology of the hybrid nanoflower material and with the retention of the activity supporting the hybrid as an acceptable enzyme mimicking material. Oxidation is mediated through hydroxyl radical formation and the order of the oxidative activity is pyrenyl > anthracenyl > naphthyl > phenyl for the inorganic-organic hybrid nanoflowers. The copper complex of pyrenyl-appended phenanthroline derivative also showed similar biomimetic activity.

Abstract
In this study, the Cu(II) complex with Zonisamide (ZNS) and 1, 10-Phenanthroline (Phen) ligands as an anticancer metallodrug was synthesized and characterized successfully by FT-IR, mass spectrometry, TGA, XPS, AAS, CHNSO, magnetic susceptibility and electrical conductivity. The interaction of Cu(II) complex with DNA was explored through a multi-spectroscopic approach such as fluorescence, UV-vis spectrophotometry, CD spectroscopy, and viscosity measurements. Molecular docking simulation was carried out to gain a deeper insight into the target site of DNA which interacted with the mentioned complex. The competitive binding tests with Hoechst 33258 showed that [CuCl2(ZNS)(Phen)EtOH].H2O can bind to the groove site of DNA. The calculated thermodynamic parameters, ΔS° = +201.15 J mol-1K-1 and ΔH° = +41.32 kJ mol-1 confirm that the hydrophobic forces and hydrogen bonding play an essential role in the binding process. The experimental and molecular modeling results demonstrate that the Cu(II) complex binds to DNA through major groove binding. Moreover, the in vitro cytotoxic effects of [CuCl2(ZNS)(Phen)EtOH].H2O against B92 cancer cell lines showed better activity in Cu(II) complex in comparison to free ZNS. Therefore, [CuCl2(ZNS)(Phen)EtOH].H2O can open a new horizon in the treatment of glioma cancer by ZNS metallodrugs.Communicated by Ramaswamy H. Sarma.

Abstract
Copper(i) complexes [Cu(L1-7)2](ClO4) (1-7) of bidentate ligands (L1-L7) have been synthesized via spontaneous reduction and characterized as catalysts for aromatic C-H activation using H2O2 as the oxidant. The single crystal X-ray structure of 1 exhibited a distorted tetrahedral geometry. All the copper(i) complexes catalyzed direct hydroxylation of benzene to form phenol with good selectivity up to 98%. The determined kinetic isotope effect (KIE) values, 1.69-1.71, support the involvement of a radical type mechanism. The isotope-labeling experiments using H218O2 showed 92% incorporation of 18O into phenol and confirm that H2O2 is the key oxygen supplier. Overall, the catalytic efficiencies of the complexes are strongly influenced by the electronic and steric factor of the ligand, which is fine-tuned by the ligand architecture. The benzene hydroxylation reaction possibly proceeded via a radical mechanism, which was confirmed by the addition of radical scavengers (TEMPO) to the catalytic reaction that showed a reduction in phenol formation.

Abstract
In this study, 9-anthraldehyde-N(4)-methylthiosemicarbazone (MeATSC) 1 and [Co(phen)2(O2CO)]Cl·6H2O 2 (where phen = 1,10-phenanthroline) were synthesized. [Co(phen)2(O2CO)]Cl·6H2O 2 was used to produce anhydrous [Co(phen)2(H2O)2](NO3)33. Subsequently, anhydrous [Co(phen)2(H2O)2](NO3)33 was reacted with MeATSC 1 to produce [Co(phen)2(MeATSC)](NO3)3·1.5H2O·C2H5OH 4. The ligand, MeATSC 1 and all complexes were characterized by elemental analysis, FT IR, UV-visible, and multinuclear NMR (1H, 13C, and 59Co) spectroscopy, along with HRMS, and conductivity measurements, where appropriate. Interactions of MeATSC 1 and complex 4 with calf thymus DNA (ctDNA) were investigated by carrying out UV-visible spectrophotometric studies. UV-visible spectrophotometric studies revealed weak interactions between ctDNA and the analytes, MeATSC 1 and complex 4 (Kb = 8.1 × 105 and 1.6 × 104 M-1, respectively). Topoisomerase inhibition assays and cleavage studies proved that complex 4 was an efficient catalytic inhibitor of human topoisomerases I and IIα. Based upon the results obtained from the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay on 4T1-luc metastatic mammary breast cancer cells (IC50 = 34.4 ± 5.2 μM when compared to IC50 = 13.75 ± 1.08 μM for the control, cisplatin), further investigations into the molecular events initiated by exposure to complex 4 were investigated. Studies have shown that complex 4 activated both the apoptotic and autophagic signaling pathways in addition to causing dissipation of the mitochondrial membrane potential (ΔΨm). Furthermore, activation of cysteine-aspartic proteases3 (caspase 3) in a time- and concentration-dependent manner coupled with the ΔΨm, studies implicated the intrinsic apoptotic pathway as the major regulator of cell death mechanism.

Abstract
Sixteen β-keto sulfide derivatives of carvacrol (4-19) incorporating phenyl or N, O and S heterocyclic moieties were synthesized in three steps. The relationships between heterocyclic structure and cupric, Cu(II), ion reducing antioxidant capacity (CUPRAC) were examined. Nine of the compounds (8-9 and 13-19) showed better CUPRAC activity than trolox at neutral pH, with trolox equivalent antioxidant capacity (TEAC) coefficients ranging between 1.20 and 1.75. Two derivatives (11-12) showed comparable reducing capacity to trolox, with TEAC values of 0.95 for 11 and 1.02 for 12. Compounds 8-9 and 11-19 were more effective at reducing the Cu(II) ion than ascorbic acid and the parent compound, carvacrol. The most effective antioxidants were those containing an oxadiazole, thiadiazole or triazole moiety. In particular, the methyl thiadiazole derivative (15) had the highest Cu(II) ion reducing capacity, with a TEAC coefficient of 1.73.
