Antioxidant Compounds from Marine Organisms

Dear Colleagues,

Oceans cover > 70% of the Earth’s surface and are a habitat for an immense variety of marine organisms. These species produce a high number of natural products, many of which exhibit important bioactivities compared to or even higher than those of terrestrial organisms. Moreover, marine organisms are often exposed to environmental stresses and extreme conditions that force them to produce protective mechanisms such as secondary metabolites and macromolecules possessing antioxidant activity. Thus, various antioxidant compounds, such as peptides, phenols, polysaccharides, carotenoids, terpenoids, polyketides, alkaloids, sterols, pigments, carbohydrates and polyunsaturated fatty acids, have been identified in a variety of marine organisms (e.g., seaweeds, microalgae, sponges, ascidians, bacteria, fungi and bryozoan). However, marine biota constitute an underexplored rich source of high-value molecules with beneficial effects for human health, and so there has been great research interest in discovering new bioactive compounds. In this Special Issue, we invite researchers to submit their latest research findings or original review articles which will bring together current research and highlight the newest data and critical discussions on the following subjects: the isolation and potency assessment of marine organisms’ antioxidant compounds (i.e., individual substances or chemical mixtures), the production of synthetic analogues based on antioxidant substances of marine origin, the role of marine organisms’ compounds in preventing oxidative stress-induced diseases and the investigation of the molecular mechanisms accounting for marine compounds’ antioxidant activity.

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. Antioxidants is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). 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.
