084P0.916 based FETs, with drain current modulation on the order of 105 and the highest charge-carrier mobility of up to 147 cm2 V-1 s-1. The physisorption of atmospheric species on the surface of the FETs is the main factor for the formation of Schottky contacts between the Au electrodes and the b-As0.084P0.916 crystal. Temperature-dependent electrical characteristics show that the Fermi level shifts from the valence band to the middle level between the conduction band and valence band as the temperature decreases. In addition, the FETs also exhibit excellent photoresponse properties from the visible to near-infrared region (450-2200 nm), with a responsivity of 37 A W-1, a specific detectivity of 7.18 × 1010 Jones, and a fast response speed (τrise ≈ 0.04 s and τdecay ≈ 0.14 s). These results suggest that b-As0.084P0.916 crystals are a promising candidate for future electronic and optoelectronic devices.A personal selection of 32 recent papers is presented covering various aspects of current developments in bioorganic chemistry and novel natural products such as neopetrothiazide from a Neopetrosia species.Mucilage is a soluble dietary fiber used as a food additive to give foods a firmer texture, aside from its many health benefits and pharmacological properties. CX-5461 It is a polysaccharide in nature, composed of large molecules of sugars and uronic acid moieties. The extraction of mucilage is achieved from a wide variety of plant parts, including rhizomes, roots, and seeds, and it has also been reported from microorganisms. In this review, the nutritional and medicinal applications of mucilage are described in the context of the different mucilage types. The current article highlights state-of-the-art valorization practices relating to mucilage and its potential novel usages in the food industry and nutraceuticals, and as a prebiotic, in addition to its nutritional and anti-nutritional values. Analysis of the prebiotic action of mucilage with respect to its structure activity relationship, as well as how it modulates gut bacteria, is presented for the first time and in the context of its known health benefits inside the colon. It is recommended that more investigations are carried out to maximize the health benefits of mucilage and ensure its safety, especially upon long-term usage.Chiral amino thioesters are important scaffolds owing to their widespread use in organic synthesis and biosynthesis. Despite their usefulness, their asymmetric synthesis, especially the catalytic asymmetric synthesis of α-chiral tetrasubstituted α-aminothioesters, is limited, with only one example reported so far. Herein, we report the first phase-transfer catalysed asymmetric synthesis of α-chiral tetrasubstituted α-aminothioesters to afford the corresponding products in up to 81% ee.Ferroptosis is a novel iron-dependent cell death pathway mainly caused by an abnormal redox state and associated with various diseases including cancer. Recently, much attention has been paid to natural compounds that are involved in its activation and inhibition. This is the first ever study to demonstrate the role of juglone isolated from Carya cathayensis green peel in inducing autophagy and inhibiting endometrial cancer (EC) cell migration. Subsequently, Fe2+ accumulation, lipid peroxidation, GSH depletion, the upregulation of HMOX1, and heme degradation to Fe2+ were reported. Juglone was involved in inducing autophagy and inhibiting cell migration and endoplasmic reticulum stress, which are the new hallmarks of cancer treatment. Collectively, our data indicate that juglone as a functional food ingredient induces the programmed cell death of EC cells by activating oxidative stress and suggest a novel therapeutic approach for the treatment and prevention of EC.Peptide-based hydrogels are physical gels formed through specific supramolecular self-assembling processes, leading to ordered nanostructures which constitute the water entrapping scaffold of the soft material. Thanks to the inherent properties of peptides, these hydrogels are highly considered in the biomedical domain and open new horizons in terms of application in advanced therapies and biotechnologies. The use of one, and only one, native peptide to formulate a gel is by far the most reported approach to design such materials, but suffers from several limitations, including in terms of mechanical properties. To improve peptide-based hydrogels interest and give rise to innovative properties, several strategies have been proposed in the recent years, and the development of multicomponent peptide-based hydrogels appears as a promising and relevant strategy. Indeed, mixing two or more compounds to develop new materials is a much-used approach that has proven its effectiveness in a wide variety of domains, incderstanding of these complex and promising systems.Myofibrillar protein accounting for about 60% of total muscle proteins is expected to be a promising source of bioactive peptides. The purpose of the present study was to purify antioxidant peptides from myofibrillar protein hydrolysate of chicken breast by ultrafiltration and gel filtration chromatography, and evaluate their chemical antioxidant activities and protective effects in H2O2-stressed NIH-3T3 cells. Four major peptides were identified using nano-LC-ESI-MS/MS as ITTNPYDY, IGWSPLGSL, ITTNPYDYHY, and LRVAPEEHPTL. The sequenced peptides were synthesized and exhibited remarkable radical-scavenging ability, ORAC (108.2-133.5 μM TE per mg peptide), and FRAP (75.4-92.5 mM Fe2+ per mg peptide). Structure-activity relationship indicated that the antioxidant capacity of the peptides was more related to the presence of hydrophobic and antioxidant amino acids (including Trp, Val, Ile, Leu, Ala, Pro, Gly, Asp, His, and Tyr) in the sequences as well as their molecular structures. Moreover, they protected NIH-3T3 cells against oxidative damage through inhibiting ROS generation and lipid peroxidation. Especially, the antioxidant peptides ITTNPYDY and IGWSPLGSL significantly (p less then 0.05) elevated intracellular glutathione level and antioxidant enzyme activities, and suppressed apoptosis by blocking caspase-3 activation. This work highlights that the selected peptides may serve as functional food ingredients with antioxidant and cytoprotective characteristics.
