Area of Science:

• Inorganic Chemistry
• Medicinal Chemistry
• Cancer Research

Background:

• Ruthenium and copper complexes are promising cancer treatment alternatives to cisplatin.
• Polyamines are crucial for cancer cell proliferation and tumorigenesis.
• Deregulated polyamine metabolism is a hallmark of cancer.

Purpose of the Study:

• Synthesize and characterize novel mono- and binuclear Ru(II) and Cu(II) complexes.
• Investigate the structure, magnetic, and dynamic properties of these metal complexes.
• Evaluate the efficacy of these complexes against advanced prostate cancer cells.

Main Methods:

• Synthesis and characterization of Ru(II) and Cu(II) complexes with polyamine ligands.
• Computer-aided analysis of electron paramagnetic resonance (EPR) spectra.
• In vitro cytotoxicity assays against PC3 prostate cancer cells.

Main Results:

• Identified Cu-N2 coordination in a distorted square planar geometry for Cu(II) complexes.
• Demonstrated high cytotoxicity of the metal complexes against PC3 cells.
• Observed inhibition of cell adhesion and migration, and reduction of reactive oxygen species.

Conclusions:

• The novel metal complexes exhibit significant anti-cancer activity against advanced prostate cancer.
• These compounds possess anti-metastatic properties by inhibiting cell migration and adhesion.
• The study highlights the therapeutic potential of polyamine-functionalized metal complexes in oncology.
