AB  - The Zn(II) complexes [Zn(HLSe2)2](NO3)2∙CH3OH (2-NO3-Se) and [Zn(HLSe3)2](NO3)2·DMF (3-NO3-Se) with selenazolyl-hydrazone ligands 4-(4-methoxyphenyl)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3-selenazole (HLSe2) and 4-(4-methylphenyl)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3-selenazole (HLSe3) have been synthesized and characterized using singe crystal X-ray diffraction analysis. Antiproliferative activities of 2-NO3-Se and 3-NO3-Se, the corresponding ligands and sulphur isosteres of the complexes and the ligands were determined on non-malignant HTR-8/SVneo extravillous trophoblast cell line and malignant JEG-3 and JAr choriocarcinoma cell lines. All Zn complexes exhibited cytotoxic effect, comparable to that of a reference metal-based drug, cisplatin. The antioxidant activity of all compounds was determined in three antioxidant assays: ORAC (Oxygen Radical Absorbance Capacity), ABTS [(2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt] and CERAC [Ce(IV)-based reducing capacity]. As a result of synergy between Zn(II) and selenazolyl-hydrazone ligands, the complexes 2-NO3-Se and 3-NO3-Se appeared to be more active than Trolox, which is not the case for their sulfur counterparts. In-silico calculations of ADME properties pointed that the compounds possess some of desirable Lipinski rule principles. Applied algorithms did not report the compounds as potential PAINS or covalent inhibitors, although due to high molecular weight none of the compounds represent a potential lead compound. Toxicity prediction of the compounds is performed using machine learning models. The complexation of the ligands most likely reduces their toxicity or reduces their negative metabolic effects.

AB  - In search for antitumor metal-based drugs that would mitigate the severe side-effects of cisplatin, Ru(II) complexes are gaining increasing recent interest. In this work, we report on the synthesis, characterization (1H- and 13C-NMR, FT-IR), and cytotoxicity studies of two new half-sandwich organometallic Ru(II) complexes of the general formula [Ru(η6-arene)(XY)Cl](PF6) where arene = benzene or toluene and XY = bidentates: dipyrido[3,2-a:2′,3′-c]phenazine (dppz) or 2-(9-anthryl)-1H-imidazo[4,5-f][1,10]phenanthroline (aip), which are bound to Ru(II) via two phenanthroline-N atoms in a characteristic “piano-stool” configuration of Ru(II)-arene complexes—as confirmed by vibrational and NMR spectra. In addition, cytotoxic studies were performed for similar half-sandwich organometallic [Ru(η6-p-cymene)(Me2dppz)Cl]PF6 complex (Me2dppz = 11,12-dimethyl-dipyrido[3,2-a:2′,3′-c]phenazine). This study is complemented with elaborate modeling with density functional theory (DFT) calculations, which provided insight into reactive sites of Ru(II) structures, further detailed by molecular docking on the B-DNA dodecamer, which identified binding sites and affinities: most pronounced for the [Ru(η6-benzene)(aip)Cl](PF6) in both A-T and G-C regions of the DNA minor groove. Cytotoxic activity was probed versus tumor cell lines B16, C6, and U251 (B16 mouse melanoma, C6 rat glioma, U251 human glioblastoma) and non-tumor cell line HACAT (HACAT normal human keratinocytes).

AB  - Novel metal-based compounds with therapeutic potential have become the subject of intense investigations in inorganic chemistry and biomedical science. Recently, strong dose-dependent cytotoxic activities of selenosemicarbazone metal complexes against several human cancer cell lines were demonstrated. The aim of the present study was to investigate in vitro antioxidative potential of Ni(II), Cd(II) and Zn(II) selenosemicarbazone complexes. All three investigated complexes exhibited high 2,2'-azinobis(3-ethyl-benzothiazoline-6-sulphonic acid) radical cation (ABTS(center dot+)) scavenging capacity, comparable with ascorbic acid. In an acute toxicity study, administration of the compounds was performed orally to mice at single doses. The mice were observed for clinical signs, body weight effects and mortality for 14 days, after which they were sacrificed for gross organ necropsy. The body weight did not vary after administration, and the autoptic analysis failed to show appreciable macroscopic alterations of internal organs. Generally, the compounds exhibited low toxic effects as required for further in vivo therapeutic studies.
AB  - Nova jedinjenja na bazi metala sa terapeutskim dejstvom postala su predmet istraživanja u neorganskoj hemiji i biomedicinskim naukama. Pokazana je jaka dozno-zavisna citotoksična aktivnost kompleksa selenosemikarbazona na većem broju ćelijskih linija humanih ćelija kancera. Cilj rada je ispitivanje in vitro antioksidativnog dejstva selenosemikarbazonskih kompleksa nikla, cinka i kadmijuma. Sva tri ispitivana kompleksa pokazala su jaku antioksidativnu aktivnost prema ABTS radikalu, uporedivu sa aktivnošću askorbinske kiseline. Tokom ispitivanja akutne toksičnosti, jedinjenja su oralno davana miševima u pojedinačnim dozama i praćeni su klinički znaci, težina tela i mortalitet nakon 14 dana, a potom su životinje žrtvovane radi autopsije organa. Težina tela nije varirala nakon aplikacije. Generalno, jedinjenja su pokazala mali toksični efekat što i zahteva buduće in vivo terapeutsko ispitivanje.

Generally, the compounds exhibited low toxic effects as required for further in vivo therapeutic studies., Nova jedinjenja na bazi metala sa terapeutskim dejstvom postala su predmet istraživanja u neorganskoj hemiji i biomedicinskim naukama. Pokazana je jaka dozno-zavisna citotoksična aktivnost kompleksa selenosemikarbazona na većem broju ćelijskih linija humanih ćelija kancera. Cilj rada je ispitivanje in vitro antioksidativnog dejstva selenosemikarbazonskih kompleksa nikla, cinka i kadmijuma. Sva tri ispitivana kompleksa pokazala su jaku antioksidativnu aktivnost prema ABTS radikalu, uporedivu sa aktivnošću askorbinske kiseline. Tokom ispitivanja akutne toksičnosti, jedinjenja su oralno davana miševima u pojedinačnim dozama i praćeni su klinički znaci, težina tela i mortalitet nakon 14 dana, a potom su životinje žrtvovane radi autopsije organa. Težina tela nije varirala nakon aplikacije. Generalno, jedinjenja su pokazala mali toksični efekat što i zahteva buduće in vivo terapeutsko ispitivanje.",
