Coligand-Dependent Cellular Effects and DNA/BSA Binding of Ruthenium(II) Tris(pyrazolylmethane) Complexes Monocationic [RuCl(κ3-tpm)(L)(PPh3)]Cl (L = PPh3, 1; NCMe, 2; 1,3,5-triaza-7-phosphaadamantane (PTA), 3; phosphinoferrocene, 4; 3-methyl-pyrazole, 5; NH2(CH2)2OH, 6; NH2(CH2)2(4-C6H4OH) (tyramine), 7; cyclohexylamine, 8; NH2CH2CH2NH2, 9; tpm = tris-pyrazolylmethane) and bis-cationic ruthenium complexes [RuCl(κ3-tpm)(PPh3)(LL’)][NO3]2 (LL′ = ethylenediamine, 10; 1,10-phenanthroline, 11; 2-picolylamine, 12; N-phenyl-1-(2-pyridinyl)methanimine, 13) and [RuCl(κ3-tpm)(PPh3)(NCMe)2][NO3]2 (14) were evaluated for their anticancer potential. Complexes 4–9 and 13–14 are novel and were obtained in 72–98% yields from thermal exchange reactions of 1. They were characterized by IR and multinuclear NMR spectroscopy, and the solid-state structures of 4, 5, 6, 7, and 14 were determined by single-crystal X-ray diffraction. Complexes 3–8 and 10–14 were further examined for solubility and stability in aqueous media, and octanol/water partition coefficients. The complexes were assessed for their in vitro cytotoxicity on a panel of six cancer and two normal cell lines. Complex 1 and the ruthenium-ferrocenyl conjugate 4 revealed significant-to-moderate activity against the cancer cells, with IC50 values ranging from 1.8 to 25.2 μM. Mechanistic studies in A2780 cells included time-dependent cytotoxicity, intracellular ruthenium uptake, cell cycle analysis, autophagy induction, production of ROS (reactive oxygen species), and mitochondrial membrane potential measurements. Moreover, a detailed study was conducted to evaluate DNA and bovine serum albumin (BSA) binding capacity. Overall, the results revealed distinct potential mechanisms of action driven by ligand diversity, specifically mitochondrial uncoupling for 1 and 4, and apoptosis- and necrosis-induced cell death for 13 and 14.

With #AI adoption accelerating, #ruthenium is shifting from niche to strategic metal.

Investors & governments are watching closely & supply is concentrated while demand is surging.

The stakes are high.

#AI #TechMetals #Ruthenium #canada #cdnpoli @mark-carney.bsky.social

Why the sudden interest?

The #AI boom is driving demand for ultra-efficient semiconductors & memory chips.

#Ruthenium has unique properties that makes it ideal for advanced circuitry. Its resistance to corrosion & excellent conductivity. It's perfect for the job.

The ruthenium and rhodium revival Niche industrial demand and new AI applications are contributing to a price spike which is hugely beneficial to the sector

#Ruthenium is quietly becoming the star of precious metals in 2025

It’s not just rare, it’s critical for electronics, catalysis & #AI

SA is 71% world’s primary ruthenium supply this year.

Withthe rapidly rising demand we need to find new sources
