Electron-Shuttling Characteristics of Cassia obtusifolia Seed Extracts and Antiviral Activities of Anthraquinone Compounds Through In Silico Studies

Processes, Год журнала: 2025, Номер 13(2), С. 458 - 458

Опубликована: Фев. 8, 2025

Previous studies have linked the electron-shuttling properties of Traditional Chinese Medicine (TCM) species to antiviral efficacy. This study explores potential Cassia obtusifolia seeds through electrochemical analyses using microbial fuel cells (MFCs) and cyclic voltammetry (CV) complemented by in silico methods. The phytochemical contents antioxidant activity seed extracts were assessed correlated with bioenergy generation stability. A principal component analysis (PCA) indicated that influence Cassia’s power-generating potential. MFC revealed a 1.87-fold power amplification unprocessed water extract (CTS-W), while CV demonstrated enhanced stability reversibility due presence (ES) species. In analyses, including network pharmacology molecular docking, provided supporting evidence for bioactive metabolites seeds, particularly targeting Hepatitis B virus-related genes. Furthermore, mathematical model highlighted superior therapeutic efficacy compared antioxidants disease treatment. These findings demonstrate strong correlation between C. extracts, suggesting bioenergy-mediated mechanisms may play crucial role development effective therapies.

Effective water management in large river basins requires a comprehensive understanding of policy effectiveness and regulatory frameworks. However, quantitative assessments water-related policies remain limited. Here, we propose novel framework for evaluating basins, providing an intuitive systematic approach decision-makers. Using the Yellow River Basin-the second-largest basin China-as case study, constructed database 1271 spanning 68 cities. We assessed completeness nine representative policies, identifying key gaps environment governance. To evaluate effectiveness, developed system integrating two subsystems: resource utilization treatment, incorporating climatic, economic, industrial factors. Our findings reveal that governance were more effective than those targeting utilization, though their impact was delayed by one to years. Furthermore, risk-based analysis pinpointed critical challenges each city, offering actionable insights optimization. This provides robust scalable assessing complex with global applicability improving

A Universal Approach to Anchoring Chromophores onto Magnetic Scaffold for Achieving Easily Recyclable Heterogeneous Photocatalytic Systems

Advanced Science, Год журнала: 2025, Номер unknown

Опубликована: Март 26, 2025

Photocatalysis based on chromophores such as porphyrin, coumarin, anthraquinone, and pyrene is a promising technology to achieve green synthesis of various high-value chemicals, but the robust non-covalent immobilization onto light-inert scaffolds for industrialization-oriented heterogeneous photocatalysis remains challenging. In this work, simple universal strategy presented preparing highly efficient recyclable photocatalysts from chromophores, which achieved via biotinylation chromophore molecules subsequent supramolecular binding chromophore-biotin dyads streptavidin-decorated magnetic beads. As an example, commercial beads modified by 5,10,15,20-tetrakis(4-aminophenyl) porphyrin not only possessed remarkable photocatalytic activities oxidative coupling benzylamine derivatives oxidation thioanisole with highest product yields beyond 95% turnover numbers approaching 10000, driven photogenerated reactive oxygen species also demonstrated impressive chemical stability recyclability separation during 10 successive test cycles. The findings revealed in work pave way advancing valuable organic compounds pharmaceutical industry, agricultural sector, etc., rationally designed systems.
