Summary: This article discusses the roles of diatomic molecules O-2, NO, and CO in biology, as well as the sensing proteins developed by nature to perceive and respond to changes in their levels. It focuses on heme-based proteins and their advanced structural and electronic adjustments for sensing, along with their possible role in redox sensing. Finally, the potential therapeutic interventions on these gas sensors and the design of small diatomic molecules for medical treatments are highlighted.

Summary: In this study, iron and ruthenium half-sandwich compounds were synthesized and characterized, and their cytotoxicity and biomolecular interactions were investigated. The results showed that the cytotoxicity of the heterodinuclear complexes increased with the distance between the iron and ruthenium ions, which was consistent with their DNA affinity.

Summary: We have successfully synthesized photoactivable ruthenium nitrosyl complex nanoparticles, and characterized their sizes using atomic force microscopy and nanoparticle tracking analysis. The nanoparticles released nitric oxide (NO) upon irradiation at 365 nm, with a quantum yield of about 0.04. Electron paramagnetic resonance and NO sensor measurements confirmed the NO release. These nanoparticles offer spatiotemporal control of NO release and hold great potential as NO nanoplatforms for biological applications.

Summary: Here we present a cobalt catalysed one-pot synthesis of the dimethylacetal of acetaldehyde from synthesis gas and methanol. The resulting product can be used as a fuel additive directly or after transacetalisation with long-chain alcohols. The synthesis is achieved at moderate temperatures with high selectivities and CO-conversions. Variation of the promotor metal and support material in the catalyst reveals their significant impact on catalyst activity and structure. Additionally, temperature and pressure variations provide insight into the ongoing processes.

Summary: The study found that combinations of CORM-2 or CORM-3 with RuCl3 significantly enhanced inhibition of venom activity in certain cases, but not in all venoms and to varying degrees. On the other hand, carboplatin antagonized the inhibition of venom activity mediated by CORM-2. Further investigation is needed to understand the potential of platinoid formulations as antivenoms.

Summary: The poor water solubility and instability of Ru(II) carbonyl complex restrict its use as CO-releasing materials (CO-RMs) for therapeutic applications. In this study, a robust Ru(I) carbonyl sawhorse skeleton was modified with a water-soluble PEGylated sidearm to enhance the hydrophilicity and bioactivity of CO. The results showed that both the bridging carboxylate ligands and PEGylated axial ligands regulate the hydrophilicity of the CO-RMs. CO-RM 4-13 exhibited sustained release of therapeutic amounts of CO under photolysis conditions. The more hydrophilic CO-RMs released CO at a faster rate, as demonstrated by the correlation between CO release kinetics and hydrophilicity. Additionally, the low cytotoxic CO-RM 4 displayed specific anticancer activity against HT-29 tumor cells.

Summary: We synthesized cis-[Ru(bpy)2(NO2-kappa N)Ln-](n-1) and cis-[Ru(bpy)2(NO2-kappa O)L n -](n-1) by reacting cis-[Ru(bpy)2(H2O) Ln-](n-2) with sodium nitrite or conducting basic cis-[Ru(bpy)2NO(Ln-)](n-3) hydrolysis. Photolysis at the metal-ligand charge transfer band (MLCT) of the isomers released nitric oxide (NO) at different rates. We investigated endothelium-dependent vasodilation induced by cis-[Ru(bpy)2(4-pic)(NO2-kappa N)]+ and cis-[Ru (bpy)2(4-pic)(NO2-kappa O)]+ in aortic rings and found that the release of NO was three times faster for cis-[Ru(bpy)2(NO2-kappa O)Ln-](n-1) compared to cis-[Ru(bpy)2(NO2-kappa N)Ln-](n-1).

Summary: A nanoarchitectural approach was used to load mesoporous halloysite nanotubes with RuCo nanoparticles for Fischer-Tropsch catalysis. The resulting catalyst exhibited high activity, low selectivity to methane and CO2, high selectivity to C5+ hydrocarbons, and a chain growth index of 0.853. The choice of reducing agent during synthesis played a crucial role in the reducibility and selectivity of the RuCo catalysts.

Summary: A systematic study was conducted on the influence of phosphine additives on the activity of a ruthenium catalyst in reductive amination without an external hydrogen source. It was found that nonhindered triarylphosphines with electron acceptor groups are the most effective activating agents, while trialkylphosphines strongly deactivate the ruthenium catalyst.

Summary: Histamine, an important biological chemical mainly found in seafood, causes an undesirable inflammatory response when consumed in large amounts. Conventional methods for detecting histamine are slow, but Molecular Impression Polymers (MIPs) offer a more efficient option. In this study, MIPs were synthesized using a simple method and successfully detected histamine in canned tuna.

Summary: The role and reactivity of metal complexes in interacting with DNA, especially metallonitrosyl compounds, have been poorly investigated. A nitrosyl compound cis-[Ru(bpy)(2)(SO3)(NO)](PF6)(A) exhibited promising biological activities, while a final product cis-[Ru(bpy)(2)(SO3)(H2O](B) showed important reactivity with H2O2 causing DNA degradation. The aqua product of the nitrosyl ruthenium complex should be further studied for its potential genotoxicity to DNA.

Summary: Sodium nitroprusside (SNP), a drug used to treat severe hypertension in hospital emergency settings, has emerged with new clinical uses in recent years. This drug functions by releasing nitric oxide (NO), but due to its short lifetime, NO donor molecules are used for administration. Currently, there are various drug delivery strategies that can overcome the limitations of SNP, providing new opportunities for its use. This Perspective highlights the properties of SNP and emphasizes the potential therapeutic uses arising from the use of drug delivery systems such as silica-based nanoparticles.

Summary: Unlike single component drugs, cocrystals have limited understanding and research on their polymorphism. This study reports the discovery of two polymorphic cocrystals from metronidazole benzoate using salicylic acid and fumaric acid as coformers. The crystal structures were analyzed and showed differences in packing and conformation, indicating distinct polymorphs. Thermal analysis and powder X-ray diffraction were performed to investigate the interconversion dynamics between the polymorphic forms.

Summary: This study achieved optimized growth conditions for reducing compositional segregation in (K,Na)NbO3-based crystals produced by the vertical Bridgman-Stockbarger (VB-S) method. This was done through a complete analysis of the thermal properties of the precursor oxides and selecting suitable crucible dimensions based on theoretical models. Chemical analysis showed very small effective segregation coefficients in both radial and longitudinal directions of the grown crystals, indicating the possibility of growing single crystals by VB-S even for incongruent compounds.
