The design of the dinuclear Ru(II) complex () with strong near-infrared (NIR) absorption properties has been reported for efficient anticancer phototherapy. Under 700 nm LED light excitation, exhibited remarkable synergistic type I/II photosensitization ability and photocatalytic activity toward intracellular biomolecules. showed impressive 700 nm light-triggered anticancer activity under normoxia and hypoxia compared with the clinically used photosensitizer Chlorin e6. The mechanistic studies showed that induced intracellular redox imbalance and perturbed the energy metabolism and biosynthesis in A549 cancer cells. Overall, this work provides a new strategy for developing efficient metal-based complexes for anticancer phototherapy under NIR light.

A method to synthesize cofacial dimeric porphyrins bearing eight corannulene units has been developed. It relies on the stability of octahedral CO-capped Ru(II) complexes linked by N-donor ligands. This specific arrangement provides an optimal scaffold to accommodate fullerenes by imposing corannulene groups at a precise distance and relative orientation.

Benzoate-bridged paddlewheel diruthenium(II,II) complexes ([RuII,II2(RArCO)(L)] (L = axial ligand); [RuII,II2]) exhibit reversible redox activity involving the oxidized species [RuII,III2]. The redox activity can be finely tuned over a broad potential range by altering the substituent R on the benzoate-bridging ligand RArCO. The electronic contributions of the substituents R depend on their type and position, as was empirically demonstrated by Hammett for substituents at the - and -positions.

Ruthenium complexes are among the most extensively studied and developed luminescent transition-metal complexes for anticancer applications. Dinuclear Ru(II) complexes have caught significant interest for larger size, higher charge, and variable complex shapes. In this concept, we have explored past and recent works on the possible biological applications of versatile tetrapyrido[3,2-a : 2,3-c : 3,2-h : 2''',3'''-j]phenazine (tppz)-based dinuclear Ru(II) complexes with a focus on their use as quadruplex DNA probes, organelle imaging, and phototherapeutic agents.

This study investigates the effects of Pt and Ru complexes containing a Schiff base with a diimine structure on Alzheimer's disease. The Schiff base (N1E,N2E)-N1,N2-bis(isoquinolin-4-ylmethylene)benzene-1,2-diamine (I) and the novel Pt(II) and Ru(II) complexes (Ia and Ib) were synthesized and characterized using FTIR, NMR (H, C), mass spectrometry, and elemental analyses. Their ability to inhibit amyloid beta (Aβ) aggregation was determined in vitro using the SH-SY5Y cell line.

Herein, we describe and investigate biological activity of three octahedral ruthenium(II) complexes of the type [Ru(CN)(phen)], -, containing a π-expansive cyclometalating substituted benzo[]quinoxaline ligand (CN ligand) (phen = 1,10-phenanthroline). Compounds - in cervical, melanoma, and colon human cancer cells exhibit high phototoxicity after irradiation with light (particularly blue), with the phototoxicity index reaching 100 for the complex in most sensitive HCT116 cells. accumulates in the cellular membranes.
