Special Issue Information
Dear Colleagues,
The discovery during the mid-last century of the first marine steroids with unprecedented structures has opened a large avenue of marine investigations. Thus far, several hundreds of unique steroids have been provided from the marine world, exhibiting a remarkable variety of substitutions and rearrangements. Some of them revealed significant biological activities, including cytotoxic, antimicrobial, antiparasitic, antiviral, anti-inflammatory, and cardiovascular activities.
The most promising unconventional steroid, namely the unusual sulfated aminosterol squalamine, originally isolated from the dogfish Squalus acanthias as a powerful antibiotic, has revealed significant antiangiogenic activity. Squalamine is currently in advanced clinical trials in the treatment of ovarian cancer and also of age-related macular degeneration. Its potential application in Parkinson’s disease has also been suggested. More recently, sterol sulfates appeared as regulatory molecules, able to control the growth of a marine diatom bloom.
While the interest of sterol in ecological studies as biomarkers or for antifouling is pointed out, steroids have been continuously isolated from diverse marine organisms, including sponges, starfishes, gorgonian corals, as well as marine microorganisms. Their structures with unusual side chains are elucidated in detail, their potential biological activities and their mechanisms of action have been intensively investigated.
This Special Issue of Marine Drugs aims to provide recent studies on marine steroids, encompassing novel structures and biosynthetic routes, potential medical applications and ecological roles within the marine organisms and their environments.

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. 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 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.
