Special Issue Information

Dear Colleagues, 

The biodiversity of oceans favor the production of a large variety of novel molecules, with a relevant pharmaceutical potential. In fact, marine organisms may offer peculiar structural and functional features as compared to terrestrial ones. In the last years, molecular techniques facilitated the discovery of bioactive compounds from marine organisms, also due to the rapid diffusion of marine genomics, becoming available to an international scientific community. The development of genome sequencing technologies to find novel metabolites has definitely drown the attention of pharmaceutical industries, along with a drop of interest towards terrestrial natural products due to the advent of combinatorial chemistry. The advent of genome-based sequencing techniques, as for example the establishment of the genome mining, has permitted to obtain new natural drugs in a faster and cheaper way, proposing new challenges in the science of natural products discovery. New compounds were derived from the marine environment by ecologically-friendly approaches without impact on the environment and the use of destructive collection practices. Genome analysis shed light on the presence of several biosynthetic gene clusters, which could be involved in the synthesis of other secondary metabolites. Innovation in this field is very rapid, as revealed by the funding of several Seventh Framework Programme (FP7) and Horizon 2020 projects under the topic “Blue Growth”, where most projects had a common final goal of meeting the urgent need to discover new drug entities, to counteract the increased incidence of deadly diseases (such as cancer) and the reduced efficacy of existing drug. In this Special Issue, contributions on marine natural products isolated by molecular approaches are welcome, with applications in pharmacological, cosmeceutical and nutraceutical fields, aiming at solving issues related to human diseases.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Angiotensin I-converting enzyme (ACE) is an important blood pressure regulator. In this study, we aimed to investigate the ACE-inhibitory effects of meroterpenoids isolated from the brown alga, Sargassum macrocarpum, and the molecular mechanisms underlying ACE inhibition. Four fractions of S. macrocarpum were prepared using hexane, chloroform, ethyl acetate, and water as solvents and analyzed for their potential ACE-inhibitory effects. The chloroform fraction showed the strongest ACE-inhibitory effect, with an IC50 value of 0.18 mg/mL. Three meroterpenoids, sargachromenol, 7-methyl sargachromenol, and sargaquinoic acid, were isolated from the chloroform fraction. Meroterpenoids isolated from S. macrocarpum had IC50 values of 0.44, 0.37, and 0.14 mM. The molecular docking study revealed that the ACE-inhibitory effect of the isolated meroterpenoids was mainly attributed to Zn-ion, hydrogen bonds, pi-anion, and pi–alkyl interactions between the meroterpenoids and ACE. These results suggest that S. macrocarpum could be a potential raw material for manufacturing antihypertensive nutraceutical ingredients. Full article

Abstract
The sea cucumber body wall was subjected to enzymatic hydrolysis using papain. The relationship between the enzyme concentration (1–5% w/w protein weight) and hydrolysis time (60–360 min) and the degree of hydrolysis (DH), yield, antioxidant activities, and antiproliferative activity in a [...] Read more.
The sea cucumber body wall was subjected to enzymatic hydrolysis using papain. The relationship between the enzyme concentration (1–5% w/w protein weight) and hydrolysis time (60–360 min) and the degree of hydrolysis (DH), yield, antioxidant activities, and antiproliferative activity in a HepG2 liver cancer cell line was determined. The surface response methodology showed that the optimum conditions for the enzymatic hydrolysis of sea cucumber were a hydrolysis time of 360 min and 4.3% papain. Under these conditions, a 12.1% yield, 74.52% DH, 89.74% DPPH scavenging activity, 74.92% ABTS scavenging activity, 39.42% H2O2 scavenging activity, 88.71% hydroxyl radical scavenging activity, and 9.89% HepG2 liver cancer cell viability were obtained. The hydrolysate was produced under optimum conditions and characterized in terms of its antiproliferative effect on the HepG2 liver cancer cell line. Full article
