The crystallographic data obtained from single crystal X-ray analysis showed that the compound adopts the monoclinic system, space group P2₁/n, with the following parameters a = 10.8317(8) Å, b = 9.0529(5) Å, c = 13.7032(9) Å, β = 99.243(3) °, Z = 4 and V = 1326.27(15) ų. The stability of the supramolecular structure was ensured by hydrogen bonding contacts with N-H…O lengths ranging between 2.749 and 2.940 Å. According to the results of Hirshfeld analysis, O…H interactions constitute the main intermolecular interaction contacts (46 %). The thermal decomposition of the precursors, studied by TGA and DSC analysis, indicates that the compound exhibits thermal stability up to 130 °C, beyond which it degrades. Infrared and Raman spectra were recorded at room temperature, confirming the existence of vibrational modes corresponding to organic and inorganic groups. Additionally, the optical properties of the synthesized compound exhibit UV–Visible absorption and interesting photoluminescence properties.

To be part of a hopeful awakening, this work aimed to synthesize four novel skipped diene-3-halocoumarin conjugates coded SDC1-SDC4 and explore their biosafe functions as anticancer and antibacterial alternatives. In the first step of their synthesis, mequinol reacts with ethyl-2-haloacetoacetate through a H₂SO₄-catalyzed Pechmann reaction, yielding 3-halo-6-methoxy-4-methylcoumarins. The in situ-generated Vilsmeier-Haack reagent formylated these trifunctionalized coumarins to create their 7-carbaldehyde congeners. Finally, the target conjugates were prepared by condensing the latter compounds with 2,4-pentadione through the modified Claisen-Schmidt reaction. The molecular structures involving their stereochemistry were established for SDC1-SDC4 by analyzing their spectra released from FTIR, ¹H NMR, ¹³C NMR, and HRMS. On the other hand, the anticancer and cytotoxicity of these conjugates were investigated against eight cancer and three healthy cell lines, respectively, using an MTT-probing technique. Four pathogenic and three commensal aerobes were the microbes utilized to evaluate the antibacterial and microbiota compatibility, respectively, employing a broth microdilution methodology. The results indicated that the conjugate with the highest anticancer attribute and lowest cytotoxicity was <strong>SDC1</strong>, while <strong>SDC2</strong> demonstrated the greatest antibacterial attribute with minimal microbiota toxicity. These findings projected the influence of a 3-position substitute of the coumarin backbone on the biological activities under research. From these, it is concluded that the chemical structures of <strong>SDC1</strong> and <strong>SDC2</strong> may represent potent anticancer cytocompatible and antibacterial microbiota-compatible scaffolds, respectively.</div></div>","PeriodicalId":420,"journal":{"name":"Results in Chemistry","volume":"11 ","pages":"Article 101846"},"PeriodicalIF":2.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142427129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The substitution of Zr and Nb into SBA-15 introduces active sites into the material, rendering it a potential catalyst for acid catalysis reactions. However, discussions regarding the acid properties and metal-support interactions in amorphous silicas functionalized with metals are limited in computational chemistry. This study aims to determine the acid strength and charge transfer effects between Zr(IV) and Nb(V) species in mesoporous silica by proposing a representative SBA-15 cluster of type 5–6. Density Functional Theory (DFT) simulations were conducted using the B3LYP/6-31G(d,p)/def2TZVP levels. The model successfully replicated trends from larger clusters, demonstrating that the more grafted onto the silica structure (i.e. have more Si-O-M bonds), the greater the acid strength of the active site. Additionally, it was found that ZrSBA-15 structures are more stable than NbSBA-15 and possess higher acid strength, a trend supported by experimental observations. The results also suggest that Nb(V) species are more effectively stabilized in ZrSBA-15 than SBA-15, likely due to the presence of Zr(IV) centers in ZrSBA-15. This research contribute to a better understanding of how the support affects the stabilization of active phases, paving the way for the rational design of silica-based heterogeneous catalysts.</div></div>","PeriodicalId":420,"journal":{"name":"Results in Chemistry","volume":"11 ","pages":"Article 101814"},"PeriodicalIF":2.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142427053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The complex formation involves I₂ acting as a Lewis acid with electron-rich PVP as a Lewis base through a charge transfer mechanism. UV–visible spectroscopy revealed a red shift of the absorption peak at 337 nm for irradiated PVP-I2 samples, indicating stronger interactions between the triiodide ion (I₃¯) and irradiated PVP. FTIR analysis confirmed the formation of new C≡N moieties arising from PVP-I2 complexation. The FT-Raman analysis revealed a new C≡N peak at 2360 cm⁻¹ in irradiated PVP-I2 samples, with increasing intensity correlating to higher irradiation doses, indicating enhanced electron delocalization due to complex formation. XRD analysis showed that PVP-I2 samples irradiated at 0 and 10 kGy exhibited higher crystallinity than those irradiated at 20 and 30 kGy, suggesting that high-dose irradiation causes PVP radiolysis and ring opening. Dielectric measurements demonstrated enhanced polarizability and ionic conductivity of irradiated PVP-I2 films, related to structural disorder promoting charge dissociation and ion mobility. The direct bandgap decreased from 2.75 eV for unirradiated samples to 2.55 eV for samples irradiated at 30 kGy, indicating the creation of new optically active defect states. Urbach energy increased from 0.85 eV to 1.55 eV with increasing irradiation dose, confirming increased disorder in the PVP structure. These findings reveal that gamma irradiation significantly alters the optical and electrical properties of PVP-I₂ films by creating defects and disrupting structure, offering new insights for tailoring these materials for optoelectronic applications.</div></div>","PeriodicalId":420,"journal":{"name":"Results in Chemistry","volume":"11 ","pages":"Article 101827"},"PeriodicalIF":2.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142426237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we developed PLGA nanoparticles coated with folate-conjugated chitosan (osthole-PLGA-NPs/CS-FA) to deliver osthole to cancer cells and investigated its inhibitory and molecular signaling mechanisms in the PANC-1 pancreatic cancer cell line. Field emission scanning electron microscopy (FESEM) revealed that osthole-PLGA-NPs/CS-FA had a spherical structure with a uniform size distribution. Dynamic light scattering (DLS) analysis showed an average size of 171.76 nm, a dispersion index 0.26, and a surface charge of + 33.08 mV, indicating stability and uniform dispersion. Fourier-transform infrared (FTIR) spectrum analysis confirmed the successful incorporation of osthole into the PLGA nanoparticles, with an encapsulation efficiency of 93.12 %. These physicochemical properties suggest efficient cellular uptake and targeted delivery. The antioxidant potential of osthole-PLGA-NPs/CS-FA was evaluated using the ABTS assay, showing concentration-dependent inhibition of free radicals with an IC₅₀ value of 172.95 μg/mL. The anticancer properties were assessed using the MTT assay, demonstrating a significant and concentration-dependent cytotoxic effect on PANC-1 cells (IC₅₀ = 31.2 μg/mL) with minimal impact on normal human foreskin fibroblast (HFF) cells.
