Special Issue Information

Dear Colleagues,

In the past few decades, marine natural product research has focused a great deal on sponges. Recently, the number of scientific papers on microbial natural products derived from sponges have been increasing. Although new sources are being explored for collecting sponges for the search of novel compounds for new drugs, there is also an increasing awareness in protecting the environment. Marine natural products scientists have gone through a more ecological and sustainable way to source novel bioactive compounds from sponges. This led scientists to focus more on bioactive secondary metabolites from sponge-derived microorganisms. In the past, it has also been questioned who was the main producer of these unique natural products, considering their structural similarity with microbial metabolites.

In this Special Issue, we would like to revisit the current researches done on bioactive compounds from marine sponges. However, with the current trends in marine natural products research, we would also like to highlight bioactive compounds isolated from sponge-derived microorganisms. I would like to invite colleagues to submit articles on their current research on bioactive compounds from marine sponges, as well as secondary metabolites from sponge-derived or -associated microorganisms.

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 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 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.

Triple negative breast cancer (TNBC) is currently the only group of breast cancers without an effective targeted therapy. Marine sponges have historically been a source of compounds with anticancer activity. In this study, we screened extracts from twenty marine sponges collected off the coast of Western Australia for cytotoxic activity against TNBC cells. One very active extract derived from the sponge Monanchora viridis was selected for bioactivity-guided fractionation. Through multiple steps of purification, we isolated a potent cytotoxic compound, which was identified as crambescidin 800 (C800). We found that C800 exhibited cytotoxic potency in a panel of breast cancer cells, of which TNBC and luminal cancer cell models were the most sensitive. In addition, C800 induced cell cycle arrest at the G2/M phase, resulting in a decline in the expression of cyclin D1, CDK4, and CDK6 in TNBC cells. This effect was associated with the inhibition of phosphorylation of Akt, NF-κB, and MAPK pathways, resulting in apoptosis in TNBC cells. Full article
