Summary: This study theoretically examined the inactivation potency of quercetin and flavonoid catecholic metabolites 1-5 on HOO center dot, CH3OO center dot, and O-2(center dot-) under physiological conditions. The results showed that the catecholic moiety of quercetin and metabolites 1-5 played a crucial role in scavenging HOO center dot and CH3OO center dot. Metabolites 1 and 5 were identified as the most potent scavengers of HOO center dot and CH3OO center dot, respectively. Quercetin exhibited higher potency in inactivating HOO center dot and CH3OO center dot via single electron transfer. The SET reaction from the 3-O-phenoxide anion of quercetin represented the most contributing reaction path. Furthermore, all polyphenolic compounds studied showed potency in inactivating O-2(center dot-) through a concerted two-proton-coupled electron transfer mechanism. These findings suggest that metabolites with high radical scavenging potency and enhanced bioavailability may contribute to the health-promoting effects attributed to parent molecules.

Summary: Taking inspiration from the food industry, an assay was developed to test the efficiency of new phenolic antioxidants by spectrophotometric measurement of the stable free radical DPPH. The kinetics of the reaction were categorized as fast, medium, or slow based on the disappearance of the absorbance band. The study also analyzed the stoichiometry of the radical scavenging reaction and its relationship with the structure-activity of phenolic antioxidants.

Summary: The reaction between the stable nitroxyl radical TEMPO center dot and the 2,2'-diphenyl-1-picrylhydrazyl radical (dpph(center dot)) is greatly accelerated in the presence of resveratrol. This surprising synergistic effect is proposed to occur through a mutual activation mechanism between TEMPO center dot/RSV, resulting in extremely fast scavenging of dpph(center dot) radical.

Summary: Crystallographic and computational studies suggest favourable interactions between polarizable arenes and halogen atoms. However, quantification of these interactions in solution has been hindered by the steric demands of the halogens. This study synthesized molecular balances and used H-1 NMR spectroscopy to quantify halogen-arene contacts in various solvents, revealing that the interaction trend is aligned with increasing exchange repulsion rather than dispersion.

Summary: This study investigates the transformation mechanisms, kinetics, and potential ecological risks of Ketamine (KET) degradation initiated by •OH/SO4•. The calculated results show that the H15 atom is more likely to be extracted, generating the most active dehydrogenated radical intermediate. The degradation products exhibit decreasing toxicity, but some remain at toxic levels. Additionally, the developmental toxicity, mutagenicity, and carcinogenicity of multiple transformation products increase compared with parent KET. This work contributes to understanding KET mineralization in liquid ecosystems and has implications for prospective industrial applications.

Summary: Idebenone is widely described as an antioxidant drug, but there is a significant discrepancy between its pharmacokinetics and achievable tissue levels in target tissues, casting doubt on our current understanding. A new framework has been proposed based on recent discoveries to explain its mode of action, providing a rational approach for testing its effects in novel indications.

Summary: This paper provides the first example of B-H...pi hydrogen bonding in a protein-ligand complex through high-resolution X-ray crystallography and quantum-chemical calculations. The study demonstrates that the B-H...pi interaction is stabilized by dispersion, followed by electrostatics. It also shows that the similar C-H...pi interaction is twice as strong, with a slightly smaller contribution of dispersion and a slightly higher contribution of electrostatics. Such insights will facilitate the rational design of future protein ligands, controlling these types of non-covalent interactions.

Summary: Developing high-performance nondoped deep-blue luminescent materials for OLEDs is important yet challenging. In this study, two highly efficient pure-blue and deep-blue materials, PIPMePBO and PIPDMePBO, were designed and synthesized. The double-methyl-substituted PIPDMePBO showed nondoped deep-blue electroluminescence with high external quantum efficiency (8.0%) and minimal efficiency roll-off (approximately 12%).

Summary: In recent years, research has been conducted on films made from biodegradable materials to improve their physical properties, mechanical strength, and hydrophobicity. This study specifically focused on banana starch-based films and their production process using cold plasma treatment. The results showed that plasma-treated films had better crystalline/amorphous ratio and improved surface properties compared to untreated films. Films produced with treated starch granules and filmogenic suspension had the lowest moisture and solubility values, while films produced with plasma-treated starch granules and subjected to plasma treatment had the highest water contact angle, tensile strength, and puncture resistance, making them the most hydrophobic and mechanically strong among the tested films.

Summary: Anthocyanins obtained from jambolan have been used in different carboxymethyl starch-based tablet formulations, with their release profiles evaluated in simulated gastric fluids and simulated intestinal fluids. The interaction between anthocyanins and carboxymethyl starch was found to be strong, and tablet dissolution behavior varied according to the pH of the media. Monolithic carboxymethyl starch tablets loaded with powdered jambolan extract efficiently delivered anthocyanins to different sites of the simulated gastrointestinal tract and maintained their antioxidant activity.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
