Pharmacological Screening

Background: Aspergillus Versicolor is a marine-derived fungus isolated from Hyrtios Erectus Red Sea sponge. Methods: The aim of this study was to carry out a pharmacological screening and investigation for the in vitro biological activity (antioxidant, cholinergic, antidiabetic and anticancer) of Aspergillus Versicolor crude extract’s active compounds by using different qualitative and quantitative methods. Results: The present study results showed that Aspergillus Versicolor crude extracts contain 0.6 mg total phenolic/mg crude extract. Aspergillus Versicolor also showed a potent antioxidative capacity by decreasing the oxidation of ABTS. The anticancer and inhibitory effects of Aspergillus Versicolor crude extracts on PTK and SHKI were found to be 75.29 % and 80.76%; respectively. The AChE inhibitory assay revealed that Aspergillus Versicolor extracts had an inhibitory percentage of 86.67%. Furthermore, the anti-inflammatory activity using COX1, COX2, TNF, and IL6 was 77.32, 85.21 %, 59.83%, and 56.15%; respectively. Additionally, the anti-viral effect using reverse transcriptase enzyme showed high antiviral activity with 92.10 %. Conclusion: The current study confirmed that the Aspergillus versicolor crude extract and its active constituents showed strong effects on diminishing the oxidative stress, neurodegenerative damage, antiinflammatory, anti-cancer and anti-viral, suggesting their beneficial role as a promising fermented product in the treatment of cancer, oxidative stress, Alzheimer's, anti-inflammatory and anti-viral diseases.

New Compounds

Chemical investigation of a Red Sea Spongia sp. led to the isolation of four new compounds, i.e., 17-dehydroxysponalactone (1), a carboxylic acid, spongiafuranic acid A (2), one hydroxamic acid, spongiafuranohydroxamic acid A (3), and a furanyl trinorsesterpenoid 16-epi-irciformonin G (4), along with three known metabolites (−)-sponalisolide B (5), 18-nor- 3,17-dihydroxy-spongia-3,13(16),14-trien-2-one (6), and cholesta-7-ene-3β,5α-diol-6-one (7). The biosynthetic pathway for the molecular skeleton of 1 and related compounds was postulated for the first time. Anti-inflammatory activity of these metabolites to inhibit superoxide anion generation and elastase release in N-formyl-methionyl-leucyl phenylalanine/cytochalasin B (fMLF/CB)-induced human neutrophil cells and cytotoxicity of these compounds toward three cancer cell lines and one human dermal fibroblast cell line were assayed. Compound 1 was found to significantly reduce the superoxide anion generation and elastase release at a concentration of 10 μM, and compound 5 was also found to display strong inhibitory activity against superoxide anion generation at the same concentration. Due to the noncytotoxic activity and the potent inhibitory effect toward the superoxide anion generation and elastase release, 1 and 5 can be considered to be promising anti-inflammatory agents.

Metabolomics Analysis

Background: The Red Sea sponges have been endorsed as a plentiful source of bioactive compounds with promising anti-cancer and anti-inflammatory activities; therefore, exploring their potential as a source of anti-cancer metabolites has stimulated a growing research interest. Purpose: To investigate the anti-cancer and anti-inflammatory potential of the Red Sea sponges, in their bulk and silver nanostructure. Metabolomics analysis of the selected sponge followed by molecular docking studies, will be conducted to explore and predict the secondary metabolites that might provide its capability of inhibiting cancer. Materials and Methods: We prepared a chloroform extract (CE) and ethyl acetate extract (EE) of the Red Sea sponge Phyllospongia lamellosa synthesized silver nanoparticles. The prepared silver nanoparticles were characterized through UV–vis spectrophotometric, transmission electron microscopy (TEM), and Fourier-transform infrared spectroscopy (FTIR) analyses. Testing for their anti-cancer activities was performed against MCF-7, MDB-231, and MCF-10A cells. Anti-inflammatory activity against COX-1 and 2 was assessed. Furthermore, liquid chromatography–mass spectrometry (LC–MS)-based metabolomics analysis and molecular docking were also applied.

Marine natural products from seaweeds have been the focus of research for novel products of pharmacological interest. Bioactivities of the phytochemicals derived from marine algae are important ingredients in many products, such as cosmetics and drugs for treating cancer and other lifestyle disorders. In this context, the aim of the present study is to compare the anti-inflammatory, analgesic, antipyretic properties of the purified terpenoids from the selected red algae Hypnea musciformis, Gracilaria dura and Kappaphycus alvarezii. Initially, the acute toxicity of the purified terpenoid extract was analyzed and was greater than 4000 mg/kg bw. In vitro BSA denaturation assay revealed significant % inhibition as compared to control. In the carrageenan induced paw edema, the purified terpenoids extract of H. musciformis exhibited remarkable soothing activity with 68.8% percentage of inhibition, which was comparable with that of indomethacin. Meanwhile G. dura and K. alvarezii showed 53 and 50% of inhibition respectively. Analgesic activity was determined by hot plate and acetic acid induced writhing test. In the hot plate test, terpenoids extract of H. musciformis and G. dura significantly increased the hot-plate latency as compared to normal saline, which reflects their analgesic efficacy. In the writhing test, terpenoid extracts from H. musciformis, G. dura and K. alvarezii inhibited the writhing response induced by acetic acid in a concentration dependent manner that suggests its varied mode of inhibition of stretching episodes. Lastly, the antipyretic activity was analyzed. Terpenoid extracts from H. musciformis, G. dura and K. alvarezii revealed a significant (P < 0.01) antipyretic activity up to 180 min.  In summary, the study demonstrates the anti-inflammatory, analgesic and antipyretic effects of terpenoids extracts from H. musciformis, G. dura and K. alvarezii on experimental models, suggesting its therapeutic potential in the treatment of peripheral painful and inflammatory pathologies.

Thuwalallenes A–E (1–3, 5 and 8) and thuwalenynes A–C (4, 6, 7), new C15 acetogenins featuring uncommon ring systems, along with cis-maneonene D (9), thyrsiferol (10) and 23-acetyl-thyrsiferol (11) were isolated from the organic extract of a population of the red alga Laurencia sp., collected at Rose Reef off the village of Thuwal in the Red Sea waters of the Kingdom of Saudi Arabia. The structure elucidation of the isolated natural products was based on extensive analysis of their spectroscopic data. Compounds 1–6, 8, 10 and 11 were evaluated for their anti-inflammatory activity by quantifying nitric oxide (NO) release in response to TLR4 stimulation in macrophages. Besides compound 4 that did not exhibit any activity, all other tested metabolites inhibited NO production from activated macrophages. Among them, thyrsiferol (10) and 23-acetylthyrsiferol (11) displayed activity with IC50 values in the low nM scale without cytotoxicity.
