Background/Objectives: Recently, there has been great interest in metallopharmaceuticals as potential anticancer agents. In this context, presented studies aim to synthesize and evaluate of two copper(II) complexes derived from phthalazine- imidazoline-based ligands against on three human cancer cell lines: cervix epithelial line (HeLa), breast epithelial-like adenocarcinoma (MCF-7), triple–negative (MDA-MB-231), well non-tumorigenic (HDFa). Moreover their antimicrobial, antioxidant properties were assessed. Methods: The synthetized compounds—both free L1, L2, L3 C1 C2—were characterized by elemental analysis, infrared spectroscopy. Additionally, a single-crystal X-ray diffraction we performed for ligand its complex C2. stability Cu(II)-complexes C2 was evaluated UV-Vis cytotoxic potency estimated HeLa, MCF-7, MDA-MB-231, non-cancerous HDFa use an MTT assay after 48 h incubation. Moreover, the antimicrobial activity L1 using reference strains following bacteria yeasts: Staphylococcus aureus, Escherichia coli, Candida albicans. radical scavenging corresponding C1, tested with colorimetric methods—ABTS, DPPH, reduction ability (FRAP). ADME webtool used assess drug-likeness synthesized compounds, physicochemical pharmacokinetic properties. Results: Copper(II) exhibited antitumor towards MDA-MB-231 compared Cisplatin (cancer viability rate 23.6% vs. 22.5%). At concentration 200 μg/mL, less than normal, skin fibroblast According vitro tests, reduced cells about 57.5–81.2%. It evident that all compounds devoid antibacterial or antifungal activity. assays revealed moderate antiradical effect observed containing phthalazin-1(2H)-imine ABTS (IC50 = 23.63 µg/mL). Conclusions: most potent compound bearing phthalazin-1(2H)-one scaffold. None showed This feature seems be beneficial terms uses agents future. only phthalazin-1(2H)-imine.

Conformation-Associated C···dz2-PtII Tetrel Bonding: The Case of Cyclometallated Platinum(II) Complex with 4-Cyanopyridyl Urea Ligand

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(7), P. 4052 - 4052

Published: April 5, 2024

The nucleophilic addition of 3-(4-cyanopyridin-2-yl)-1,1-dimethylurea (1) to cis-[Pt(CNXyl)2Cl2] (2) gave a new cyclometallated compound 3. It was characterized by NMR spectroscopy (1H, 13C, 195Pt) and high-resolution mass spectrometry, as well crystallized obtain two crystalline forms (3 3·2MeCN), whose structures were determined X-ray diffraction. In the structure 3, conformers (3A 3B) identified, while 3·2MeCN had only one conformer 3A. differed orientation N,N-dimethylcarbamoyl moiety relative metallacycle plane. both crystals 3 3·2MeCN, molecules Pt(II) complex are associated into supramolecular dimers, either {3A}2 or {3B}2, via stacking interactions between planes metal centers, which additionally supported hydrogen bonding. theoretical consideration, utilizing number computational approaches, demonstrates that C···dz2(Pt) interaction makes significant contribution in total forces geometrically optimized dimer [3A]2 reveals dz2(Pt)→π*(PyCN) charge transfer (CT). presence such CT process allowed for marking C···Pt contact example rare studied phenomenon, namely, tetrel bonding, site acts Lewis base (an acceptor noncovalent interaction).
