Special Issue Information

Dear colleagues:

Nowadays, at least one-third of the current top-twenty drugs on the market are derived from a natural source, and approximately 50% of the marketed drugs are classified as naturally-derived or are designed on the basis of natural compounds. Marine biodiversity is huge and is correlated with a wide chemical diversity in their compounds, most of them still unknown or uncharacterized. In fact, it is estimated that only 18% of marine natural products have been discovered so far compared with products of terrestrial organisms.

Small molecules, such as small peptides, polyphenols and terpenoids, are especially interesting due their particular pharmacological and pharmacokinetic properties. This Special Issue is focused in these small molecules from marine origin with special interest in the following topics:

  • New small molecules with pharmacological activity and their molecular targets.
  • Anticancer, antimicrobial and antinflammatory small marine molecules.Use of small marine compounds in other diseases.
  • Use in cosmetic, cosmoceutic and nutraceutic products.
  • Purification, chemical characterization  and structural elucidation.
  • In silico virtual screenings and HTS studies.
  • Pharmakokinetics and bioavailability studies.
  • Preclinical and clinical trials.

The aim of this Special Issue is to collect literature that reflect the actual state-of-the-art and increase our knowledge about marine small molecules and their biological activities.

As Guest Editor of this Special Issue, I cordially invite researchers from all around the world to contribute to this Special Issue by submitting original research articles, long and mini review papers, short notes, and opinions according to their expertise.

Title: Antiproliferative effects of invertebrate marine extracts on human colon cancer cell lines
Authors: Verónica Ruiz-Torres, Enrique Barrajón-Catalán and Vicente Micol
Abstract: Marine organisms represent a promising and unexploited source of bioactive molecules for drug discovery. Marine natural products (MNPs) are considered an interesting source of anticancer compounds. To date, five of these compounds have been approved for use as pharmaceutical drugs in cancer treatment and seventeen are in the pipeline of compounds for testing in clinical trials. This paper shows a screening of the antiproliferative activity of extracts derived from marine invertebrates in human colon cancer cell models. A total of twenty dichloromethane extracts and their fractions (ethyl acetate, hexane and butanol) were assayed for their antiproliferative activity using the MTT colorimetric method for cytotoxicity, the real time cellular analyzer (RTCA) and the clonogenic assay. Two nudibranch (NA and NB), an holothurian (PS) and a soft coral (CR) complete extracts showed the best cytotoxic activity using HGUE-C-1, HT29 and SW480 colon cancer cells. The main compounds of the complete extracts were identified by using a high-performance liquid chromatography coupled to mass spectrometry detection (HPLC-MS). Anexin V and mitopotencial tests indicated that marine extracts promoted cell death through an apoptotic pathway and a cytostatic effect with cell cycle arrest. The cytotoxic properties of the tested extracts observed in this preliminary screening suggest the presence of compounds with pharmacological potential but further investigations are required to determine the responsible compounds and its putative mechanism.
