Rhodium(III) complexes have gained attention for their anticancer potential. In this study, we investigated a rhodium(III) bipyridylsulfonamide complex (2) and its ligand (L) for their effects on breast cancer (SKBr3) and noncancerous mammary cells (HB2). Both compounds significantly reduced oxidative phosphorylation (OXPHOS) and mitochondrial function in SKBr3 cells while sparing HB2 cells. Compound 2 also increased glycolysis in both lines, suggesting a metabolic shift. Mitochondrial size and shape were altered, particularly in SKBr3 cells. Additionally, both compounds reduced cancer cell migration by disrupting actin cytoskeleton organization and the Rac1/VASP signaling pathway. These findings suggest that the rhodium(III) bipyridylsulfonamide complex selectively impairs mitochondrial dynamics and cell migration in cancer cells while sparing healthy cells, providing insight into its mechanism of action and toward its use as targeted anticancer therapy. This study lays the groundwork for future in vivo studies and further optimization of these metal-based therapeutics for clinical applications.
