Summary: A novel copper (II) complex was successfully synthesized and characterized for its binding properties with CT-DNA and HSA. The complex exhibited intercalative bindings with CT-DNA and HSA, resulting in fluorescence quenching. In vitro assays showed the complex's superior anti-proliferative effects on various cancer cell lines compared to cisplatin, with dose- and time-dependent induction of apoptosis/necrosis and cell cycle arrest at G0/G1 phase in HepG2 cells.

Summary: Metformin forms stable complexes with copper ions, leading to enhanced antiproliferative effect in cancer cells. It reduces cell number and viability in SW1222 and K562 cells, as well as in K562-200 multidrug-resistant cells. Additionally, metformin has been noted to have lower cancer incidence in diabetic patients.

Summary: In this study, three new organic ligands (L1, L2, and L3) and their corresponding copper coordination compounds (Cu(L1)Cl2, Cu(L2)Cl2, and Cu(L3)Cl2) were synthesized. The compounds were characterized using various analytical techniques and it was found that the complexation proceeded in a bidentate manner. The antimicrobial and cytotoxic activities of the compounds were investigated, and Cu(L3)Cl2 showed the strongest antibacterial properties and L1 complex exhibited increased toxicity against cancer cells.

Summary: In this work, a new monofunctional gold(III) complex was synthesized and characterized. The substitution reactions between the complex and biomolecules were found to be dependent on the nature of the entering nucleophile. The substitution mechanism was proposed to be associative based on the calculated values of entropy and enthalpy. Additionally, the complex interacted with DNA and protein, exhibited significant cytotoxic activity against human oral squamous carcinoma cells, and affected cell cycle and proliferation.

Summary: Two new Cu(II) complexes with good water solubility were synthesized and characterized in this study. The complexes showed strong inhibitory activity against bacteria and cancer cells, potentially related to their interaction with DNA. In addition, the complexes induced apoptosis in cells through DNA damage and ROS-mediated mitochondrial dysfunction pathways. Moreover, in vivo studies demonstrated that one of the complexes inhibited tumor growth more effectively than cisplatin.
