Summary: This study proposes the use of pyrazole derivatives and polymer microspheres for anticancer treatment. Experimental results show that the tested pyrazole derivatives and their modified microspheres have anti-proliferative activity in vitro. Some of the modified substances exhibit the greatest ability to inhibit divisions of all cancer cells. Molecular docking studies reveal that these compounds bind to the human EphB1 receptor, and the compounds with the highest antiproliferative activity have a better fit to the active site.

Summary: New rhenium(I) tricarbonyl complexes based on the phenanthroline ligand were designed and synthesized to investigate the role of carbazole and pyrrolidine substituents in determining thermal, electrochemical, and optoelectronic properties. The impact of pyrrolidine and carbazole on the ground and excited-state properties of the complexes were investigated, and the results were supported by theoretical calculations. The HOMO and LUMO energy levels were affected by the substituents, and the structural modification also resulted in noticeable changes in the electrochemical and photophysical behavior of the complexes.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
