Although inspiring progress has been achieved in tumor nanocatalytic therapies based on tailor-made nanozymes for converting hydrogen peroxide into reactive oxygen species (ROS) efficiently, most cytotoxic hydroxyl radicals do not spread far enough within a cell to damage the primary organelles for effective tumor therapy due to their short half-life time (?1¦Ìs). Developing a novel nanocatalyst platform involving longer half-life time ROS is desired. To this end, Fe3O4-Schwertmannite nanocomposites (Fe3O4-Sch) with triple-effect tumor therapy are constructed through a facile method. The Schwertmannite shell converts the ¡¤OH produced by Fe3O4 via the Fenton reaction into sulfate radicals with a longer half-life time (30¦Ìs). Combination of dual radicals exhibits overwhelming tumor inhibition efficacy. The nanocomposites also show the multifunctionality of good photothermal efficiency (33.2%) and synergistic oxidative stress amplification upon glutathione biosynthesis (GSH) depletion by the L-buthionine sulfoximine (BSO) mols. loaded in the hollow Fe3O4 cores. The comprehensive properties of the nanoplatform including the dual-radical production, Fe3O4 nanocrystal mediated PTT, and the BSO mediated GSH depletion result in remarkable tumor inhibition both in vitro and in vivo, which may pave a way to constructing a synergic catalytic nanoplatform for efficient tumor therapy.

Oregano (Origanum vulgare L.) is mainly cultivated, both as fresh and dried herb, for several purposes, such as ailments, drugs, and spices. To evaluate the influence of some drying methods on the chem. composition of the essential oil of oregano, its aerial parts were dehydrated by convective drying techniques (shade, static oven), microwave-assisted heating (three different treatments) and osmotic treatment. The oils were analyzed by GC-FID and GC-MS. The highest essential oil yield was achieved from microwave and shade drying methods. In total, 39 components were found, with carvacrol (ranging from 56.2 to 81.4%) being the main constituent; other compounds present in lower amounts were p-cymene (1.6-17.7%), ¦Ã-terpinene (0.8-14.2%), ¦Á-pinene (0.1-2.1%), thymol Me ether (0.4-1.8%) and thimoquinone (0.5-3.5%). The essential oil yields varied among the different treatments as well as the relative compositions The percentages of p-cymene, ¦Ã-terpinene and ¦Á-pinene decreased significantly in the dried sample compared with the fresh sample; on the other hand, carvacrol, isoborneol and linalool increased significantly in the dried materials. The choice of the drying method for obtaining the essential oil therefore appears crucial not only in relation to the higher yield but also and above all in reference to the percentage presence of components that can direct the essential oil toward an appropriate use.

Artemisia is one of the most diverse genera in the Asteraceae family. The genus is wildly distributed in Irano-Turanian habitats and includes 34 species in Iran. Here, for the first time the essential oil variability, antioxidants and anti-cholinesterase and anti-tyrosinase activities of extracts of three Artemisia species (A. tournefortiana, A. khorassanica, A. haussknechtii), from different regions of Iran were evaluated. Based on GC-MS analyses, 81.84% to 98.70% of the total oils were identified. Cluster anal. grouped the studied populations in three different chemotypes. The highest and the lowest essential oil contents were observed in A. khorassanica and A. haussknechtii species, resp. Camphor, en-in-dicycloether, 1,8-cineole and (Z)-¦Â-farnesene were the dominant components of essential oil in investigated ecotypes. The results revealed that the total phenol content was higher in A. tournefortiana collected from Kerman and A. haussknechtii collected from Chaharmahal and Bakhtiari. However, the lowest phenol content was recorded for A. haussknechtii collected from Isfahan province. The highest flavonoids content was found in A. tournefortiana collected from West Azerbaijan and A. khorassanica collected from North Khorasan. The highest FRAP antioxidant activity was observed in A. tournefortiana (Kerman) and the lower amount was in A. haussknechtii collected from Kohgiluyeh and Boyer-Ahmad. The highest antioxidant activity by DPPH method was in A. khorassanica collected from South Khorasan and the lowest activity was in Isfahan’s A. haussknechtii. The acetycholine esterase inhibitory activity was higher in A. tournefortiana collected from West Azerbaijan; and the lowest activity was in A. haussknechtii collected from Chaharmahal and Bakhtiari province.

In the presence of KOH, NH-sulfoximines react with pentafluoropyridine to give N-(tetrafluoropyridyl)sulfoximines (NTFP-sulfoximines) I (R1 = Me, Ph, 4-MeC6H4, 4-ClC6H4, etc.; R = Me, i-Pr, 2-Py, 2-thiophenyl, etc.; ) in moderate to excellent yields. Either a solution-based or a superior solvent-free mechanochem. protocol can be followed. X-Ray diffraction analyses of 26 products provided insight into the bond parameters and conformational rigidity of the mol. scaffold. In solid-state structures, sulfoximines with halo substituents on the S-bound arene are intermolecularly linked by C-X¡¤¡¤¡¤O=S (X = Cl, Br) halogen bonds. Hirshfeld surface anal. is used to assess the type of non-covalent contacts present in mols. For mixtures of three different S-pyridyl-substituted NTFP-sulfoximines and N-iodosuccinimide (NIS) in CDCl3, association constants were determined by 1H NMR spectroscopy. The data revealed a dependence of the halogen bond strength on the position of the pyridyl nitrogen indicating the presence of N-I¡¤¡¤¡¤N(S-pyridyl) interactions. Neither the S=O oxygen nor the tetrafluoropyridyl-substituted nitrogen of the sulfoximine appeared to be involved in halogen bonding.

Processing is the crucial factor for green tea aroma quality. In this study, the aroma dynamic changes throughout the manufacturing process of chestnut-like aroma green tea were investigated with gas chromatog. electronic nose (GC-E-Nose), gas chromatog.-ion mobility spectrometry (GC-IMS), and comprehensive two-dimensional gas chromatog. coupled to time-of-flight mass spectrometry (GC x GC-TOFMS). GC-IMS identified 33 volatile compounds while GC x GC-TOFMS identified 211 volatile components. Drying exerted the greatest influence on the volatile components of chestnut-like aroma green tea, and promoted the generation of heterocyclic compounds and sulfur compounds which were commonly generated via the Maillard reaction during the roasting stage. A large number of heterocyclic compounds such as 1-methyl-1H-pyrrole, pyrrole, methylpyrazine, furfural, 2-ethyl-5-methylpyrazine, 1-ethyl-1H-pyrrole-2-carboxaldehyde, and 3-acetylpyrrole were newly formed during the drying process. This study also validated the suitability of GC-E-Nose combined with GC-IMS and GC x GC-TOFMS for tracking the changes in volatile components of green tea throughout the manufacturing process.
