The influence of thioether-substituted ligands in dicopper(II) complexes: Enhancing oxidation and biological activities. J Inorg Biochem 2024; 256:112573. [PMID: 38678913 DOI: 10.1016/j.jinorgbio.2024.112573] [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: 02/23/2024] [Revised: 04/15/2024] [Accepted: 04/22/2024] [Indexed: 05/01/2024]
Abstract
This paper describes the synthesis, structural analysis, as well as the magnetic and spectroscopic characterizations of three new dicopper(II) complexes with dinucleating phenol-based ligands containing different thioether donor substituents: aromatic (1), aliphatic (2) or thiophene (3). Temperature-dependent magnetometry reveals the presence of antiferromagnetic coupling for 1 and 3 (J = -2.27 cm-1 and -5.01 cm-1, respectively, H = -2JS1S2) and ferromagnetic coupling for 2 (J = 5.72 cm-1). Broken symmetry DFT calculations attribute this behavior to a major contribution from the dz2 orbitals for 1 and 3, and from the dx2-y2 orbitals for 2, along with the p orbitals of the oxygens. The bioinspired catalytic activities of these complexes related to catechol oxidase were studied using 3,5-di-tert-butylcatechol as substrate. The order of catalytic rates for the substrate oxidation follows the trend 1 > 2 > 3 with kcat of (90.79 ± 2.90) × 10-3 for 1, (64.21 ± 0.99) × 10-3 for 2 and (14.20 ± 0.32) × 10-3 s-1 for 3. The complexes also cleave DNA through an oxidative mechanism with minor-groove preference, as indicated by experimental and molecular docking assays. Antimicrobial potential of these highly active complexes has shown that 3 inhibits both Staphylococcus aureus bacterium and Epidermophyton floccosum fungus. Notably, the complexes were found to be nontoxic to normal cells but exhibited cytotoxicity against epidermoid carcinoma cells, surpassing the activity of the metallodrug cisplatin. This research shows the multifaceted properties of these complexes, making them promising candidates for various applications in catalysis, nucleic acids research, and antimicrobial activities.

Abstract
Three new trisubstituted 4f- and 4d tungstoantimonates (TA) K3Na21[(M(CH3COO))3(HPO3)(WO4)(SbW9O33)3]·nH2O {M3(HPO3)Sb3W28} (M = GdIII, YIII, YbIII, n = 35–36) were synthesized using a double-template synthetic approach. Following their characterization in the solid state employing single- and powder X-ray diffraction (XRD), IR-spectroscopy, and elemental – and thermogravimetric analyses (TGA), {M3(HPO3)Sb3W28} were subjected to a comprehensive set of solution characterization methods including UV/vis- and multinuclear 31P and 13C NMR spectroscopy. All representatives were shown to be highly active, recyclable, and stable Lewis-acid catalysts towards the nerve agent simulant O,O-dimethyl O-(4-nitrophenyl) phosphate (DMNP) at neutral pH (in Tris–HCl [125 mM] at pD 7.0 25 °C). Control experiments showing catalytic activity of the unsubstituted trilacunary TA [SbW9O33]9− suggest the non-innocence of Tris in the DMNP hydrolysis for the first time. With 3 Mio. people worldwide being yearly exposed to organophosphates (OPs), accounting for approximately 300 000 deaths, OPs are a current threat to mankind. This work reports on {M3(HPO3)Sb3W28} and {SbW9} as recyclable OP degradation catalysts.![]()

Abstract
Organophosphates are a class of organic compounds that are important for living organisms, forming the building blocks for DNA, RNA, and some essential cofactors. Furthermore, non-natural organophosphates are widely used in industrial applications, including as pesticides; in laundry detergents; and, unfortunately, as chemical weapons agents. In some cases, the natural degradation of organophosphates can take thousands of years; this longevity creates problems associated with handling and the storage of waste generated by such phosphate esters, in particular. Efforts to develop new catalysts for the cleavage of phosphate esters have progressed in recent decades, mainly in the area of homogeneous catalysis. In contrast, the development of heterogeneous catalysts for the hydrolysis of organophosphates has not been as prominent. Herein, examples of heterogeneous systems are described and the importance of the development of heterogeneous catalysts applicable to organophosphate hydrolysis is highlighted, shedding light on recent advances related to different solid matrices that have been employed.

Abstract
![]()
We report on a family of five new
4f- and 4d-doped sandwich-type
germanotungstates with the general formula [(n-C4H9)4N]l/mH2[(M(H2O)3)(γ-GeW10O35)2]·3(CH3)2CO [M(H2O)3(GeW10)2] (M = CeIII, NdIII, GdIII, ErIII, l = 7; ZrIV, m = 6), which have been synthesized
at room temperature in an acetone–water mixture. Among the
compound series, [Zr(H2O)3(GeW10)2]8–, which has been obtained in the
presence of 30% H2O2, represents the first example
of a 4d-substituted germanotungstate incorporating the intact dilacunary
[γ-GeIVW10O36]8– building block. All compounds were characterized thoroughly in the
solid state by single-crystal and powder X-ray diffraction (XRD),
IR spectroscopy, thermogravimetric analysis (TGA), and elemental analysis
and in solution by NMR and UV–vis spectroscopy. The phosphoesterase
activity of [Ce(H2O)3(GeW10)2]9– and [Zr(H2O)3(GeW10)2]8– toward the model substrates 4-nitrophenyl phosphate (NPP)
and O,O-dimethyl O-(4-nitrophenyl) phosphate (DMNP) was monitored with 1H- and 31P-NMR spectroscopy revealing an acceleration
of the hydrolytic reaction by an order of magnitude (kcorr = 3.44 (±0.30) × 10–4 min–1 for [Ce(H2O)3(GeW10)2]9– and kcorr = 5.36 (±0.05) × 10–4 min–1 for [Zr(H2O)3(GeW10)2]8–) as compared to the uncatalyzed reaction (kuncat = 2.60 (±0.10) × 10–5 min–1). [Ce(H2O)3(GeW10)2]9– demonstrated improved antibacterial
activity toward Moraxella catarrhalis (MIC 32 μg/mL),
compared to the unsubstituted [GeW10O36]8– POM (MIC 64 μg/mL). We report on the synthesis and characterization of five
new monosubstituted 4f- and 4d-germanotungstates [(n-C4H9)4N]l/mH2[(M(H2O)3)(γ-GeW10O35)2]·3(CH3)2CO [M(H2O)3(GeW10)2] (M = CeIII, NdIII, GdIII, ErIII, l = 7; ZrIV; m = 6). The phosphoesterase properties of [Ce(H2O)3(GeW10)2]9− and [Zr(H2O)3(GeW10)2]8− were
investigated by probing the hydrolytic activity toward 4-nitrophenyl
phosphate (NPP) and O,O-dimethyl O-(4-nitrophenyl) phosphate (DMNP). Antibacterial tests
revealed inhibiting activity of [Ce(H2O)3(GeW10)2]9− against Moraxella
catarrhalis.

Abstract
The new di- and tetranuclear Fe(III) μ-oxido complexes [Fe4(μ-O)4(PTEBIA)4](CF3SO3)4(CH3CN)2] (1a), [Fe2(μ-O)Cl2(PTEBIA)2](CF3SO3)2 (1b), and [Fe2(μ-O)(HCOO)2(PTEBIA)2](ClO4)2 (MeOH) (2) were prepared from the sulfur-containing ligand (2-((2,4-dimethylphenyl)thio)-N,N-bis ((1-methyl-benzimidazol-2-yl)methyl)ethanamine (PTEBIA). The tetrairon complex 1a features four μ-oxido bridges, while in dinuclear 1b, the sulfur moiety of the ligand occupies one of the six coordination sites of each Fe(III) ion with a long Fe-S distance of 2.814(6) Å. In 2, two Fe(III) centers are bridged by one oxido and two formate units, the latter likely formed by methanol oxidation. Complexes 1a and 1b show broad sulfur-to-iron charge transfer bands around 400–430 nm at room temperature, consistent with mononuclear structures featuring Fe-S interactions. In contrast, acetonitrile solutions of 2 display a sulfur-to-iron charge transfer band only at low temperature (228 K) upon addition of H2O2/CH3COOH, with an absorption maximum at 410 nm. Homogeneous oxidative catalytic activity was observed for 1a and 1b using H2O2 as oxidant, but with low product selectivity. High valent iron-oxo intermediates could not be detected by UV-vis spectroscopy or ESI mass spectrometry. Rather, evidence suggest preferential ligand oxidation, in line with the relatively low selectivity and catalytic activity observed in the reactions.

Abstract
Phosphoesterases hydrolyze the phosphorus oxygen bond of phosphomono-, di- or triesters and are involved in various important biological processes. Carboxylate and/or hydroxido-bridged dizinc(II) sites are a widespread structural motif in this enzyme class. Much effort has been invested to unravel the mechanistic features that provide the enormous rate accelerations observed for enzymatic phosphate ester hydrolysis and much has been learned by using simple low-molecular-weight model systems for the biological dizinc(II) sites. This review summarizes the knowledge and mechanistic understanding of phosphoesterases that has been gained from biomimetic dizinc(II) complexes, showing the power as well as the limitations of model studies.
