Ruthenium compounds, nitric oxide donors in biologic systems, have emerged as a promising therapeutic alternative to conventional drugs in anticancer chemotherapy and as a potential neuroprotective agent with fewer cytotoxic effects. This minireview summarizes promising studies with ruthenium complexes and their roles in cancer, neuroinflammation, neurovascular, and neurodegenerative diseases. The up-to-date evidence supports that ruthenium-based compounds have beneficial effects against gliomas and other types of brain cancers, reduce motor symptoms in models of cerebral ischemia-reperfusion, and may act in the control of nociceptive and inflammatory events, such as those seen in early Alzheimer's disease. More studies are needed to fill many current knowledge gaps about the intricate and complex biologic effects and therapeutic-related mechanisms of ruthenium, stimulating further research. SIGNIFICANCE STATEMENT: This minireview summarizes studies addressing the role of ruthenium compounds on neurological illnesses, focusing on brain cancer and neurovascular and neurodegenerative diseases. No such review is available in the literature.

Since Dye-Sensitized Solar Cells (DSSCs) was created, a versatile and cost-effective alternative among photovoltaic technology options for power generation and energy transition to combat climate change have emerged. The theoretical and experimental knowledge of DSSCs have increased in regard to their operation in the last three decades of development; it includes the device's components, as well as the most recent innovations in their application and forms of activation. In this work paper, we presented a meta-study of photovoltaic characterization parameters, 329 scientific reports of DSSCs were considered to compare three types of sensitizers (Organometallics, non-metal organic dyes and, natural dyes).

Beta-hydroxy ketones can be reduced using a sequence of ruthenium-catalyzed silyl etherification followed by tetrabutylammonium fluoride (TBAF) promoted intramolecular hydrosilylation. Switching from TBAF to tetrabutylammonium difluorotriphenylsilicate (TBAT), even without first forming the silyl ether, gave cyclic dioxasilinane products. These somewhat sensitive compounds could be isolated pure by column chromatography using florisil as the stationary phase.

CO2-based hydroesterification is an attractive route to produce value added ester compounds, which could replace CO-based hydroesterification processes if sufficient catalytic technologies are developed. One path to CO2-based hydroesterification is through an organoformate intermediate, which is then used in olefin hydroesterification to generate the desirable esters. This route creates a net CO2-based hydroesterification process using tandem catalytic systems for CO2 hydrogenation to organoformate paired with formate-olefin hydroesterification.

The prevalence of naphthalene compounds in biologically active natural products, organic ligands and approved drugs has motivated investigators to develop efficient strategies for their selective synthesis. C-H functionalization of naphthalene has been frequently deployed, but mainly involves two-component reactions, while multiple-component C-H functionalization for the synthesis of naphthalene compounds has thus far proven elusive. Herein, we disclose a versatile three-component protocol for the modular synthesis of multifunctional naphthalenes from readily available simple naphthalenes, olefins and alkyl bromides P(iii)-assisted ruthenium-catalyzed remote C-H functionalization.

Effective light-based cancer treatments, such as photodynamic therapy (PDT) and photoactivated chemotherapy (PACT), rely on compounds that are activated by light efficiently, and absorb within the therapeutic window (600-850 nm). Traditional prediction methods for these light absorption properties, including Time-Dependent Density Functional Theory (TDDFT), are often computationally intensive and time-consuming. In this study, we explore a machine learning (ML) approach to predict the light absorption in the region of the therapeutic window of platinum, iridium, ruthenium, and rhodium complexes, aiming at streamlining the screening of potential photoactivatable prodrugs.
