“Nutrition” and “Pharmaceutical” together build up the perception of “Nutraceuticals” that refer to the food or dietary supplements that help to incorporate additional health benefits to the fundamental sustenance accomplished on daily basis. Each nutraceutical contains one or more bioactive molecules that are usually obtained by chemical and/ or biotechnological synthesis or by extraction from natural sources. Among the natural sources, marine bionetwork possess immense potential for the presence of bioactive compounds. Some of these bioactive compounds as isolated from marine sources, have potential use as nutraceuticals. This mini review provides a brief overview of nutraceutical compounds from marine sources that are currently under research and/or have been commercialized. A detailed discussion on the biochemical categories of compounds and the marine organisms that play as potential sources of these bioactive nutraceutical compounds have been included.

The development of novel anticancer agents is essential to finding new ways to treat this disease, one of the deadliest diseases. Some marine organisms have proved to be important producers of chemically active compounds with valuable bioactive properties, including anticancer. Thus, the ocean has proved to be a huge source of bioactive compounds, making the discovery and study of these compounds a growing area. In the last few years, several compounds of marine origin, which include algae, corals, and sea urchins, have been isolated, studied, and demonstrated to possess anticancer properties. These compounds, mainly from securamines and sterols families, have been tested for cytotoxic/antiproliferative activity in different cell lines. Bioactive compounds isolated from marine organisms in the past 5 years that have shown anticancer activity, emphasizing the ones that showed the highest cytotoxic activity, such as securamines H and I, cholest-3β,5α,6β-triol, (E)-24-methylcholest-22-ene-3β,5α,6β-triol, 24-methylenecholesta-3β,5α,6β-triol, and 24-methylcholesta-3β,5α,6β-triol, will be discussed in this review. These studies reveal the possibility of new compounds of marine origin being used as new therapeutic agents or as a source of inspiration to develop new therapeutic agents.

Natural products are continually explored in the development of new bioactive compounds with industrial applications, attracting the attention of scientific research efforts due to their pharmacophore-like structures, pharmacokinetic properties, and unique chemical space. The systematic search for natural sources to obtain valuable molecules to develop products with commercial value and industrial purposes remains the most challenging task in bioprospecting. Virtual screening strategies have innovated the discovery of novel bioactive molecules assessing in silico large compound libraries, favoring the analysis of their chemical space, pharmacodynamics, and their pharmacokinetic properties, thus leading to the reduction of financial efforts, infrastructure, and time involved in the process of discovering new chemical entities. Herein, we discuss the computational approaches and methods developed to explore the chemo-structural diversity of natural products, focusing on the main paradigms involved in the discovery and screening of bioactive compounds from natural sources, placing particular emphasis on artificial intelligence, cheminformatics methods, and big data analyses.

Abstract Laurus nobilis leaves contain flavored and bioactive components with relevant biological properties for human health that are attributed to an abundant presence of highly bioactive secondary metabolites. However, the separation process for these bioactive molecules from plant matrix is seriously limited by the presence of a physical barrier (cell wall). Thus, the use of novel extraction procedures to enhance their release is particularly important. In this work, the potential use of microwave-assisted extraction (MAE) as a tool to improve the extraction efficiency of bioactive compounds from bay leaves and their characterization was evaluated. The effects of irradiation time (3, 6 and 9 min) and aqueous ethanol concentration (0, 25 and 50%) on the extraction of phenolic compounds were evaluated. A response surface methodology was applied to determine the best extraction conditions by MAE. The maximum total phenolic compound under the best conditions (9 min time irradiation and aqueous ethanol 50%) was 10.63±0.91 mg gallic acid equivalent/g plant using MAE. Also, the antioxidant potential of the extracts obtained was evaluated.

By Products

Seafood by-products, produced by a range of different organisms, such as fishes, shellfishes, squids, and bivalves, are usually discarded as wastes, despite their possible use for innovative formulations of functional foods. Considering that “wastes” of industrial processing represent up to 75% of the whole organisms, the loss of profit may be coupled with the loss of ecological sustainability, due to the scarce recycling of natural resources. Fish head, viscera, skin, bones, scales, as well as exoskeletons, pens, ink, and clam shells can be considered as useful wastes, in various weight percentages, according to the considered species and taxa. Besides several protein sources, still underexploited, the most interesting applications of fisheries and aquaculture by-products are foreseen in the biotechnological field. In fact, by-products obtained from marine sources may supply bioactive molecules, such as collagen, peptides, polyunsaturated fatty acids, antioxidant compounds, and chitin, as well as catalysts in biodiesel synthesis. In addition, those sources can be processed via chemical procedures, enzymatic and fermentation technologies, and chemical modifications, to obtain compounds with antioxidant, anti-microbial, anti-cancer, anti-hypertensive, anti-diabetic, and anti-coagulant effects. Here, we review the main discards from fishery and aquaculture practices and analyse several bioactive compounds isolated from seafood by-products. In particular, we focus on the possible valorisation of seafood and their by-products, which represent a source of biomolecules, useful for the sustainable production of high-value nutraceutical compounds in our circular economy era.

Potential Use

The food industry, in response to current consumer demand for natural and functional foods, is constantly evolving and reformulating traditional products formulations. Thus, during the last decades, multiple natural sources have been investigated to replace the need to add synthetic additives. In addition, the use of natural sources can also increase the nutritional quality of the food. With this in mind, elderberry is used in the food industry for certain purposes. However, its potential is much higher than the number of applications it currently has. Its high content of anthocyanins, as well as other polyphenols and vitamins, means that it can be used by the food industry both as a colorant and as an antioxidant. In addition, the incorporation of these bioactive compounds results in functional foods, with a high antioxidant capacity. Moreover, the inclusion of elderberry products in foods formulation increases their shelf-life, but the correct amount and strategy for adding elderberry to food should be studied to ensure a positive effect on nutritional and technological properties without affecting (or improving) the sensory quality of foods. Therefore, this manuscript aims to review the main bioactive compounds present in elderberries, as well as their potential uses in the food industry.

Bioactive Potential

Although knowledge of the bioactive compounds produced by species inhabiting coastal waters is increasing, little is known about the bioactive potential produced by marine species occupying deeper habitats with high biodiversity and productivity. Here, we investigate about the bioactive potential of molecules produced by species that inhabit the crinoid beds, a poorly known essential fish habitat affected by trawling, wherein large amounts of commercial and noncommercial species are discarded. Based on a trawl survey conducted in 2019, 14% of the 64 species discarded on crinoid beds produce molecules with some type of bioactive potential, including; soft corals (Alcyonium palmatum); tunicates (Ascidia mentula); bony fish, such as horse mackerel (Trachurus trachurus); European hake (Merluccius merluccius); and chondrichthyans, such as small-spotted catshark (Scyliorhinus canicula). In addition, 16% of the discarded species had congeneric species that produce compounds with bioactive potential, indicating that such species might also possess similar types of bioactive molecules. Molecules with antioxidant, antitumour, antihypertensive, and antibacterial properties were the most frequent, which could provide the basis for future research aiming to discover new marine-based drugs and compounds for other human uses. Among all species or genera that produce compounds with bioactive potential, 68% presented medium or high vulnerability to trawling. Results show that the discarded catch contains many species, which produce different bioactive compounds that represent an added-value resource. These results highlight the importance of manage properly crinoid beds, to ensure that species that produce molecules with bioactive potential inhabiting these habitats are protected.

Fruit bio-residues can be interesting for the recovery of bioactive molecules, such as phenolic compounds, tocopherols, vitamins, among others. These compounds can be targeted at the food industry and used for the development of functional foods or as food additives. In some cases, fruit epicarps are converted into by-products with non-commercial value, and generally, these fruit parts have a higher content in bioactive compounds than the fruit pulp. From this perspective, S. odorifera, a Brazilian fruit, has an inedible epicarp that could be explored to obtain biological compounds. Therefore, the aims of this study were to evaluate the chemical composition and the antioxidant, anti-proliferative, anti-inflammatory, and antimicrobial bioactivities of this by-product. S. odorifera epicarp showed a total of four organic acids, four phenolic compounds, highlighting the high concentration of anthocyanins (24 ± 1 mg/g dry weight (dw)) and high content of tocopherols (366 ± 2 mg/100 g dw). The hydroethanolic extract showed considerable antioxidant activity (EC50 values of 48.2 ± 0.5 and 27 ± 1 µg/mL for TBARS and OxHLIA assays, respectively), as also antibacterial and antifungal activities (minimal inhibitory concentrations (MICs) ≤ 2.2 mg/mL). The results obtained in this study suggest that Sicana odorifera epicarp represents a reliable option for the development of novel natural-based colorants with functional/bioactive proprieties.
