Carotenoids represent a large group of isoprenoid structures with many different structural characteristics and biological activities. They are the most important pigments among those occurring in the nature that are responsible for the various colors of different fruits, vegetables, and plant parts. Marine carotenoids are also responsible for the color of many fish, shellfish, and algae. However, there has been a relatively little information on the impact of marine carotenoids on human health, while there have been many papers and reviews on carotenoids of terrestrial origin.
The potential beneficial effects of marine carotenoids have been particularly focused on astaxanthin and fucoxanthin, as they are major marine carotenoids. Both carotenoids show strong antioxidant activity, which is attributed to quenching singlet oxygen and scavenging free radicals. The potential role of the carotenoids as dietary antioxidants has been suggested as being one of the main mechanisms for their preventive effects against cancer, inflammation, etc. However, it will be difficult to explain their biological activities only using antioxidant activity. Other mechanisms of action that are independent of their antioxidant properties are also likely to be important. The mechanisms should be based on the regulatory effect of marine carotenoids on particular bio-molecules. This activity of carotenoids is responsible for the characteristic chemical structures, which differ depending on the length of the polyene, nature of the end group, and various substituent they contain.
This Topical Collection of Marine Drugs is dedicated to marine carotenoids, and will be focused on the benefits of carotenoids for human beings. For a better understanding of the physiological effects of marine carotenoids, this Collection should include the most recent developments in the presence, analysis, chemistry, and biochemistry of marine carotenoids. We are very happy and honored to serve as Editors for this Collection, and would like to invite scientists to report their findings, or review the recent literature, on various aspects of marine carotenoids. We sincerely hope that this Collection will encourage other scientists to work in the exciting field of marine carotenoids.

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 papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the collection 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. Marine Drugs 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 1800 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.
