Sulfoxides can directly be converted into N-cyanosulfilimines using a new Burgess-type reagent. By applying this strategy with a related reagent variant, synthetically valuable NH-sulfoximines have been prepared from sulfoxides via N-protected sulfilimines. The practical three-step reaction sequence is generally high yielding and applicable to a wide range of substrates. The sulfoxide-to-sulfilimine conversion can also be performed under solvent-reduced conditions in a ball mill.

Due to the importance of diseases associated with oxidative stress, the search for natural antioxidants proves to be essential. This work aimed to compare the chem. composition and antioxidant potential of essential oils from the genus Lippia L. through chemometric anal. The essential oils were characterized by gas chromatog. coupled with mass spectrometry. Antioxidant potentials were determined by DPPH, ABTS, Deoxyribose and ¦Â-carotene protection, Iron chelation and reduction methods. All data were related by multivariate analyzes. Essential oils showed low similar chem. compositions and no statistically significant relationship. These showed relevant antioxidant activity, especially for L. sidoides that obtained IC50 of 5.22 ¡À 0.08¦Ìg/mL in ABTS capture. Multivariate analyzes showed the effectiveness of L. alba compounds to DPPH scavenging, Fe3+ reduction and ¦Â-carotene protection, and L. gracilis components to deoxyribose protect. Thus, studies proving the antioxidant potential of Lippia compounds against oxidative stress and their use in food conservation are fundamental.

This study aimed to investigate the microbial viability, edible qualities, and flavor volatiles of enzymically hydrolyzed ‘Orah’ (Citrus reticulata Blanco) puree seperately using Lactobacillus paracasei JLPF-176 (LP) and Bifidobacterium infantis JYBI-373 (BI) as starters during fermentation and storage. The results showed that fermented enzymically hydrolyzed citrus puree contains sufficient viable counts (6-8 log CFU/mL) during fermentation and storage. Probiotics fermentaion increased the content of organic acids, total phenolic content (TPC), total flavonoid content (TFC), antioxidant capacities, and flavanones. Storage led to an increase in soluble sugars (fructose and glucose) and a decrease in organic acid (L-tartaric acid). During the early storage weeks, the TPC, polymethoxylated flavones (PMFs), and flavanones of citrus puree fermented by LP were obviously increased, resulting in higher antioxidant capacity based on the DPPH and FRAP methods. Correspondingly, the antioxidant capacity (ABTS and FRAP) of citrus puree fermented by BI was decreased continuously during storage, which was related to the decrease in the TFC and tangeretin. A total of 24 volatile compositions were identified, and storage tended to decrease the sensory properties of citrus puree by probiotic fermentation Overall, this study provides a potential method to innovate whole citrus fruit processing technol. and improve its nutritional value.

Photodynamic therapy (PDT) has been demonstrated to be a promising strategy for the treatment of cancer, while its therapeutic efficacy is often compromised due to excessive concentrations of glutathione (GSH) as a reactive oxygen species (ROS) scavenger in cancer cells. Herein, we report the development of near-IR (NIR) photothermal liposomal nanoantagonists (PLNAs) for amplified PDT through through the reduction of intracellular GSH biosynthesis. Such PLNAs were constructed via encapsulating a photosensitizer, indocyanine green (ICG) and a GSH synthesis antagonist, L-buthionine sulfoximine (BSO) into a thermal responsive liposome. Under NIR laser irradiation at 808 nm, PLNAs generate mild heat via a ICG-mediated photothermal conversion effect, which leads to the destruction of thermal responsive liposomes for a controlled release of BSO in a tumor microenvironment, ultimately reducing GSH levels. This amplifies intracellular oxidative stresses and thus synergizes with PDT to afford an enhanced therapeutic efficacy. Both in vitro and in vivo data verify that PLNA-mediated phototherapy has an at least 2-fold higher efficacy in killing cancer cells and inhibiting tumor growth compared to sole PDT. This study thus demonstrates a NIR photothermal drug delivery nanosystem for amplified photomedicine.

In the present study the variations of biomass, essential oil content and composition of lemon verbena (Lippia citriodora) during different growth-exploitation phases from 27th May 2020 to 8th June 2021 were investigated. The uniform rooted cuttings were planted in the greenhouse under natural light. The aerial parts of lemon verbena at flowering stage were harvested at six times included 27th May (H1), 29th August (H2), 4th Nov. (H3), 17th Jan. (H4), 27th March (H5), and 8th June (H6). Hydro distillated essential oils were analyzed by using GC-FID and GC/MS techniques to determine the essential oil profile. Results showed a considerable variation in plant biomass, essential oil quantity and quality at different harvesting times. Plant biomass increased by 66.83% up to fourth harvesting time (H4) then decreased. During the studied harvesting frequencies the essential oil content of L. citriodora showed a sinusoidal trend. The highest essential oil content (0.858% v/w) and yield (17.95 L ha-1) were obtained at third harvesting time (H3) and in the followed harvesting times their contents were decreased. The observed changes in the essential oil composition of L. citriodora during different harvesting times were due to the relative proportions of constituents and the presence of new constituents. In the all essential oil samples, oxygenated monoterpenes represented by geranial (25.42-30.11%) and neral (19.81-24.19%) were the predominant compounds The highest ratio of monoterpenes to sesquiterpenes compounds (¡Ö5:1) was recorded in collected plants at third harvesting time.
