Special Issue Information
Dear Colleagues,
Oxidative stress plays a central role in the progression of numerous pathological conditions. It arises from an imbalance between the production of reactive species—such as reactive oxygen species, reactive nitrogen species, and reactive sulfur species—and the body’s capacity to neutralize them. These reactive species can damage key biomolecules, including lipids, proteins, and DNA, leading to cellular dysfunction and triggering inflammatory responses. Natural antioxidants, sourced from plants, microbes, and marine organisms, have garnered significant interest due to their ability to counteract oxidative damage. They are capable of exhibiting synergistic effects when combined or used in specific formulations, enhancing their bioavailability and efficacy. Understanding their structure–activity relationships and mechanisms of action will be crucial for guiding future drug development and nutraceutical innovation. However, the full potential of nature’s antioxidant repertoire remains largely unexplored, despite extensive global research efforts. A multitude of novel compounds are yet to be isolated and characterized, offering promising avenues for improving human health and advancing therapeutic strategies.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
