It is believed that the remarkable oxidizing nature of the gold(III) centre, which is variably modulated by the metal ligands, may play a key role in determining their reactivity with biomolecules and, hence, their mode of action. Here, we present a systematic electrochemical investigation of five structurally diverse mononuclear gold(III) complexes (i.e. Auen, Audien, Aucyclam, Aubipy and Aubipy^c) the chemical and cytotoxic properties of which have previously been determined in our laboratory. The electrochemical profiles of the panel compounds were comparatively investigated by cyclic voltammetry (CV) both in aqueous solution and in DMSO to explore solvent-dependent redox behavior under biologically relevant conditions. The results highlight the influence of ligand denticity and coordination flexibility on the stabilization of the Au(III) center and the accessibility of redox processes of the redox processes within the biological environment. The electrochemical profiles obtained for this panel of gold(III) complexes are analyzed and compared with their known biological and antiproliferative profiles to explore possible structure-activity relationships within a unified interpretative framework.</div><div>Overall, these findings highlight the delicate balance between stability and reactivity required for gold-based drugs to achieve their therapeutic effect, and suggest that electrochemical profiling can inform the rational design of redox-activated anticancer agents.</div></div>","PeriodicalId":20278,"journal":{"name":"Polyhedron","volume":"281 ","pages":"Article 117730"},"PeriodicalIF":2.6,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144860772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of these methods, sono-photodynamic therapy (SPDT), has a higher efficacy than the effective success rates of these two applications alone. The high singlet oxygen production potential of phthalocyanine complexes and their high sensitivity to sound and light make these compounds suitable sensitizers for SPDT and are of great interest to researchers. This study aims to investigate the effect of the central metal ion on the photochemical and sonophotochemical properties of phthalocyanine complexes and to evaluate their potential for use in SPDT, taking into account their singlet oxygen production. For this purpose, tetra-substituted zinc(II) (<strong>4</strong>), magnesium(II) (<strong>5</strong>) and biaxially substituted Si(IV) (<strong>6</strong>) phthalocyanines containing novel phthalonitrile derivatives were synthesized and characterized and the photochemical and sono-photochemical properties of these complexes in DMF were investigated. The results obtained from the excitation of the synthesized compounds by light irradiation and the synergistic effect of light and sound showed that singlet oxygen production increased with increasing heavy atom effect in the molecule. With the photochemical method using light irradiation, Φ_Δ values for phthalocyanines (<strong>4</strong>, <strong>5</strong> and <strong>6</strong>) were 0.58, 0.38 and 0.40, respectively, whereas with the sono-photochemical method using the synergistic effect of light and ultrasound, Φ_Δ values reached 0.70 for <strong>4</strong>, 0.54 for <strong>5</strong> and 0.58 for <strong>6</strong>. The data obtained proved that the singlet oxygen production increased slightly by changing the method from light radiation to ultrasound/light.

Except for doping with Sc and V, all 3d transition metal-doped TiBr₂ monolayers display significant magnetic moments, ranging from 1.8 to 4.6 μB, with the Co-doped configuration exhibiting the maximum moment of 4.6 μB. The total magnetic moment in the Cr-, Mn-, Fe-, and Co-doped TiBr₂ monolayers is primarily attributed to the strong hybridization between the d orbitals of the TM dopants and those of the Ti host. Conversely, in the cases of Ni, Cu, and Zn doping, the magnetic moment arises solely from the Ti-3d orbitals, indicating slight involvement of the dopant states. According to our calculations, among the 3d transition metal dopants, only the Sc impurity induces metallic behavior in the TiBr₂ monolayer.
