  the antioxidant activity results may vary with dilution volume and reaction conditions, which can affect reproducibility and comparison between studies, - the study was conducted in an animal model, and the results cannot be directly extrapolated to humans without further preclinical and clinical validation, - only two doses were tested, and a more comprehensive dose-response assessment is required to fully establish the therapeutic window, - the pharmacokinetics, bioavailability and potential toxicity of the identified phytoconstituents remain to be clarified, - while molecular docking provided valuable mechanistic insights, these predicted interactions require experimental validation

• Interactions Between Antioxidants: How Useful Are In Vitro Studies for Understanding the Action of Antioxidants in Complex Systems? (2026) · International Journal of Molecular Sciences · doi

  Taking all above aspects into account, the importance of results of studies of interactions between antioxidants for understanding the in vivo effects of antioxidants seems limited. However, in vitro studies of antioxidant interactions may be useful for food preser- vation. Studies of the interactions of antioxidants in the prevention of the oxidation of oils and other fats can be directly translated into practical protocols, allowing for limiting the amounts of antioxidant additives. However, antioxidant interactions characterized in model systems should be validated in the actual food matrix under realistic processing and storage conditions. Future studies on the in vitro interactions of antioxidants should include thorough analysis of multiple concentrations and ratios, concentration–response dependencies, ki- netic analysis, careful selection of predefined additivity models, inclusion of mechanistically distinct assays, and appropriate statistics. They should aim at elucidation of the molecular https://doi.org/10.3390/ijms27167491 Int. J. Mol. Sci. 2026, 27, 7491 29 of 36 mechanisms of the interactions, combining antioxidant assays with analytical techniques, enabling identification of intermediates, final products, and byproducts of apparently sim- ple antioxidant assays. They should use substrates and conditions relevant to physiology or food systems. Finally, they require validation in relevant food or biological systems. Un- derstanding the real course and pathways of antioxidant reactions should allow explaining and predicting interactions between antioxidants, also operating in vivo.

• Towards the Development of Effective Antioxidants—The Molecular Structure and Properties—Part 2 (2026) · Molecules · cited 18× · doi

  There is a lack of understanding of the interplay between polyphenolic architecture and electronic descriptors in antioxidant research. The paper identifies a gap in the development of effective antioxidants, which requires a precise, mechanism-driven approach. The gap is in the integration of computational models with advanced synchrotron methodologies to provide element-specific validation of antioxidant behavior.
