“…The DTA curve showed a small endothermic peak at the initial stage, which is due to the removal of water molecules in the material, and a large endothermic peak at around 800 degrees, which is due to thermal degradation. 29 , 30 In addition, the pH stability and iron release of UPBNPs-MCSNs were examined. The pH values of UPBNPs-MCSNs ranged from 9.7 to 9.5 within 270 mins, which was alkaline and decreased slightly with increasing time ( Figure 1M ).…”

Background: Mesoporous calcium-silicate nanoparticles (MCSNs) are advanced biomaterials that have been used to control drug delivery for many years. Ultrasmall Prussian blue nanoparticles (UPBNPs) showed high peroxidase and catalase-like activities. This study evaluated the antibacterial and antibiofilm properties, mechanism and cytotoxicity of UPBNPs-MCSNs composites synthesized by both as precursors. Methods: UPBNPs-MCSNs were prepared and characterized. The antibacterial effect of UPBNPs-MCSNs was evaluated by the MTT assay and CFU counting method, and their biosafety was tested by CCK8. Then explore the antibacterial mechanism, including TEM observation of bacterial morphology, and detection of bacterial ROS, LPO and GSH levels. The antibiofilm activity of UPBNPs-MCSNs was tested by E. faecalis biofilm model in human roots. The roots were pretreated with materials and cultured with E. faecalis, and the survival of E. faecalis on the root canal wall was observed by SEM and CLSM. Results: The results showed that UPBNPs-MCSNs had potent antibacterial and antibiofilm activities. They can aggregate on the dentin surface and significantly inhibit E. faecalis adhesion and colonization. Their antibacterial activity is as effective as NaClO and calcium hydroxide (CH), can significantly prolong the time of bacterial colonization than CH, but have lower cytotoxicity to normal cells. We found that UPBNPs-MCSNs trigger a like classic ferroptosis pathway in bacteria. UPBNPs-MCSNs can induce bacteria to produce ROS and LPO, and reduce GSH level. Moreover, we observed that the metal ions chelator and the antioxidant could block their antibacterial activity. Conclusion: These results reveal that UPBNPS-MCSNs have high antibacterial and antibiofilm, and can mediate the bacterial redox pathway ROS/GSH like the classical pathway of ferroptosis, providing a theoretical basis for them to develop into a safe and effective novel root canal disinfectant.

The versatility of aza- and oxa-heterocyclic compounds has garnered significant attention in recent times. A large number of currently approved pharmaceutical products include nitrogen- and oxygen-containing heterocycles. Recent nanotechnological developments have propelled an upsurge in the applications of nanocatalysis for heterocyclic synthesis. Metal nanoparticles (MNPs) have emerged as promising catalysts for the synthesis of aza- and oxa-heterocycles owing to their unique physicochemical properties. Various MNPs including gold, silver, nickel and palladium have been evaluated for their catalytic activities in different reaction types, including cyclisation, coupling, hydrogenation and oxidative transformations. The MNPs have exhibited remarkable catalytic efficiency when utilised under optimal conditions. These catalysts have showcased high reusability and recyclability, yielding satisfactory amounts of the desired heterocyclic compound. The present work provides a detailed overview of recent advances in the area of MNP-assisted synthetic construction of aza- and oxa-heterocycles, published during the previous calendar year, 2022. The review serves as a valuable resource and also paves the way for future investigations in the development of novel catalytic strategies for heterocycle synthesis.1 Introduction2 Nanocatalysis3 Aza- and Oxa-Heterocycle Synthesis Catalysed by MNPs3.1 AuNPs3.2 CuNPs3.3 CoNPs3.4 FeNPs3.5 NiNPs3.6 PdNPs3.7 PtNPs3.8 SiNPs3.9 ZnNPs3.10 Bimetallic NPs3.11 Other MNPs4 Summary and Outlook

“…As tabulated, the synthetic process of DHPMs was accomplished to both electron-donating and electron-withdrawing groups, which led to giving the desired compounds 4a-h in 91-98% yields, and the offered protocol is comprehensive (Table 2). The reaction for the synthesis of DHPMs is controlled by TLC, and the resulting products from this reaction were analyzed by 1 H and 13 C NMR and FT-IR spectrophotometers (Supporting Information S1).…”

The present study reported a novel and eco‐friendly synthesis of Fe3O4@ZIF‐8@Glycerol‐Ni nanocatalyst via a multistep process. The as‐prepared catalyst was used due to its high efficiency, low cost, and biocompatibility for the fabrication of dihydropyrimidinones by Biginelli multicomponent reactions of aryl aldehyde, ethyl acetoacetate, and urea under ambient status. X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR), Brunauer‐Emmet‐Teller (BET), vibrating sample magnetometry (VSM), scanning electron microscopy and energy dispersive X‐ray (SEM‐EDS), inductively coupled plasma (ICP), elemental mapping analysis (EMA), thermogravimetric analysis (TGA), Raman, and transmission electron microscopy (TEM) techniques were successfully utilized to evaluate the nanocatalyst. The advent of the peaks confirmed the presence of nickel on the catalyst's surface due to the oxygen and nickel, and the nanoparticle size is 10–15 nm. Eventually, nano‐heterogeneous catalyst exhibits high performance as well as good selectivity in the synthesis of dihydropyrimidinones. Also, it can be recycled up to multiple fresh runs with no significant loss of catalytic efficiency.
