“…Refs. [165,166] reported the presence of halogenated monoterpenes myrcene (one cyclic and three acyclic) in the seaweed Ochtodes secundiramea. Sesquiterpene elatol is a significant secondary metabolite identified in the red seaweed Laurencia dendroidea that protects against herbivory and fouling [167].…”

In a few Southeast Asian nations, seaweeds have been a staple of the cuisine since prehistoric times. Seaweeds are currently becoming more and more popular around the world due to their superior nutritional value and medicinal properties. This is because of rising seaweed production on a global scale and substantial research on their composition and bioactivities over the past 20 years. By reviewing several articles in the literature, this review aimed to provide comprehensive information about the primary and secondary metabolites and various classes of bioactive compounds, such as polysaccharides, polyphenols, proteins, and essential fatty acids, along with their bioactivities, in a single article. This review also highlights the potential of seaweeds in the development of nutraceuticals, with a particular focus on their ability to enhance human health and overall well-being. In addition, we discuss the challenges and potential opportunities associated with the advancement of pharmaceuticals and nutraceuticals derived from seaweeds, as well as their incorporation into different industrial sectors. Furthermore, we find that many bioactive constituents found in seaweeds have demonstrated potential in terms of different therapeutic attributes, including antioxidative, anti-inflammatory, anticancer, and other properties. In conclusion, seaweed-based bioactive compounds have a huge potential to play an important role in the food, nutraceutical, and pharmaceutical sectors. However, future research should pay more attention to developing efficient techniques for the extraction and purification of compounds as well as their toxicity analysis, clinical efficacy, mode of action, and interactions with regular diets.

“…The choice of cultivation conditions for species was based on temperature and salinity data recorded in the field, as well as previous studies in which brown algal species were maintained in the laboratory, such as D. menstrualis itself and the type species of the genus, Dictyota dichotoma. Much of the work consulted opted to maintain specimens in Provasoli culture media (Soe Pa Kyaw et al, 2009;Bogaert et al, 2016), at a temperature of 20°C, constant aeration, and a light intensity of 80 µE.m -2 .s -1 (Bogaert et al, 2016;Martins et al, 2016;Obando et al, 2022b) Photographic images were taken of some individuals within the 21 days of cultivation to monitor conditions and morphological changes (Figure 1). In the field, individuals of D. menstrualis showed very thin thalli with abnormal tips and margins and had a slimy texture, which was also reflected in the morphology of individuals in the experimental units, because the individuals monitored in vitro continued to present such characteristics, a result of their health condition in the natural environment and accentuated in the process of adaptation to the system (Figures 1F, G).…”

“…The growing demand and sustainable supply and availability of high-quality seaweed seedlings for metabolite obtaining still face many barriers. One solution for producing high quality seaweed seedlings is tissue culture or micropropagation (Obando et al, 2022b). However, there is a path to follow before embarking on this type of cultivation.…”

The seaweed Dictyotaceae family has a great wealth of diterpenes with important biological activities. Information on these diterpenes qualitative and quantitative aspects in conjunction with physiological data and abiotic parameters are essential to obtain an effective algal culture system that is a sustainable resource. In this study, the diterpene profile of Dictyota menstrualis and Canistrocarpus cervicornis were analyzed as a function of in vitro maintenance time and the influence of culture medium. The algae were collected in the state of Rio de Janeiro and subjected to an acclimation period in the laboratory. Then, the species were acclimated in aquaria containing seawater from the collection sites. Then biomass algal was divided into (i) control experiment (CC): Growth in sterilized seawater; (ii) enriched experiment (EE): Growth in sterilized seawater enriched with Provasoli/2. Triplicate experiments were maintained in vitro (2.4% m/v), and the medium was changed every 7 days. Diterpenes were monitored using dichloromethane extracts from dried algae: (a) collected in the field, (b) after the acclimation period, and (c) from experimental units taken every 7 days for a total of 21 days. Among the main results, we found response variables such as specific growth rate (SGR); moreover, positive data were obtained for the alga C. cervicornis in CC, and this was evident showing after 7 days of cultivation in the experimental control unit (CU). For D. menstrualis, the SGRs for the treatments were negative at the monitored time, which was due to biomass losses, frond breakage, and rapid decomposition of some individuals that did not withstand the stress conditions during their collection. The analysis of the chemical profile by GC-MS made it possible to monitor 12 diterpenes and one sterol in the alga D. menstrualis and 7 diterpenes in C. cervicorni. The correlations found by Generalized Linear Models (GLMs) and redundancy analysis (RDA) statistical analyzes between the diterpene profile with the monitored variables (Nitrate, ammonia and pH), showed correlations for 10 diterpenes of the species D. menstrualis and 1 of the C. cervicornis, our analyses are important for the discussion of metabolic plasticity of the Dictyotaceae family

Dictyotaceae algae have gained recognition as prolific producers of diterpenes, which are molecules with significant biotechnological potential. These diterpenes hold immense promise as potential active drug components, making the algae a compelling area of study. The present review aims to present the latest advancements in understanding the biopotential of Brazilian Dictyota and Canistrocarpus brown algae, shedding light on the remarkable diversity and the biological and pharmacological potential of the secondary metabolites they produce. A total of 78 articles featuring 26 distinct diterpenes are reported in this review, with their antiviral potential being the mosthighlighted biological activity. Despite considerable research on these algae and their diterpenes, significant knowledge gaps persist. Consequently, the present review is poised to serve as a pivotal resource for researchers who are actively engaged in the pursuit of active diterpenes beyond the immediate purview. Furthermore, it holds the potential to catalyze an increase in research endeavors centered around these algal species within the geographical confines of the Brazilian coastline. Also, it assumes a critical role in directing future scientific explorations toward a better comprehension of these compounds and their ecological implications.
