Exploring quinolinone–chalcones: Synthesis, antioxidant potential and industrial applications in biofuels

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biofuels undergo oxidative degradation, which reduces their storage stability and efficiency, hindering their large‐scale adoption and integration into the global energy matrix. To address this issue, we synthesized and characterized four novel quinolinone–chalcone derivatives (substituted with Br, Cl, OCH3 and OCH2CH3) as potential ...

Probing the Inhibitory Potential of Halogenated Symmetrical Formamidine Against MAO‐A and MAO‐B: Structural Elucidation, Molecular Dynamic Simulation and DFT Computational Studies

Chemistry &Biodiversity, EarlyView.
ABSTRACT A halogenated symmetrical formamidine, N,N′‐bis(3‐chloro‐4‐fluorophenyl)formamidine (FCF) was synthesized by the condensation reaction between triethyl orthoformate and 3‐chloro‐4‐fluoroaniline in 1:2 ratio. The compound FCF was characterized by FT‐IR, mass, NMR (1H and 13C) spectroscopic techniques and the purity was confirmed by elemental ...

グラフのゼータ関数は, 伊原[6]により定義された伊原ゼータ関数が起源である. 伊原ゼータ関数は, PGL(2, mathbb{Q}_{p})の捻れのない余コンパクトな離散部分群rから定まるセルバーグゼータ関数の類似であり, 母関数型表示と行列式表示を持つことが[6]において示された. その後, Serre[15]により, 伊原ゼータ関数は, SL(2, mathbb{Q}_{p})に付随したBruhat-Tits tree(無限正則木)のrによる商グラフ(有限正則グラフ)のゼータ関数であることが示唆され, 砂田[17, 18]によってグラフのゼータ関数が確立された. その後多くの研究者の貢献により, グラフのゼータ関数は大きく発展した.

The Effect of Exogenously Applied Dicarboxylic Acids (Photon) on the Maize (Zea mays) Metabolite Profile

Chemistry &Biodiversity, EarlyView.
ABSTRACT Maize is an important crop worldwide with approximately 1200 million tons consumed and a market size worth $143 billion. Environmental stress influence production of crops and mitigating these ensures optimum production. Dicarboxylic acids are known as emulsifying agents that mitigate various stresses in plants.

Insights into the Mechanism of a Vanadium Bromoperoxidase from the Marine Macro‐Algae Corallina pilulifera for Biocatalytic Halogenation

ChemCatChem, EarlyView.
A study of crystallographic complexes obtained from vanadium haloperoxidase enzymes can determine key amino acids, leucine, and phenylalanine, that change their structural orientation to allow either chloride or bromide to bind to the enzymes active site, thereby determining halide specificity.

A Scalable Synthesis of a New Quasi‐Reversible Redox Compound with a High Positive Redox Potential

ChemElectroChem, EarlyView.
A new redox active molecule with an extraordinary high redox potential of +1.45 V vs standard hydrogen electrode (SHE) is found. To elucidate the electrochemical redox mechanism of the 1,4‐diallyl‐2,5‐bis(allyloxy)benzene a series of model compounds was developed and electrochemically characterised.
