Given the increasing demand for sustainable bioactive compounds, this study aims to fill the gap by providing a comprehensive analysis of compounds present in red seaweed <em>Haloplegma duperreyi</em> Montague 1842, making it the first to utilize this particular seaweed species for its bioactive potential against Type 1 - Human Immunodeficiency Virus. This study exhibited promising results, where the methanolic extract showed the highest HIV-1 inhibition of 89.13 % at a concentration of 100 μg/mL with an IC₅₀ value of 8.405 μg/mL. Further fractionation yielded 12 distinct fractions, with PF3 demonstrating highest anti-HIV-1 activity, achieving 90.67 % inhibition and an IC₅₀ value of 5.557 μg/mL, which is close to the efficacy of positive control, zidovudine (AZT). Characterization of PF3 using FTIR, NMR, and GC–MS identified key functional groups such as N<img>H, C<img>O, C<img>N, and C<img>Br, indicative of piperazine derivatives, known for their diverse antiviral properties. The study calculated the therapeutic index (TI) for both the methanolic extract and PF3 fraction, with values of approximately 23 and 31, respectively, indicating a favourable safety profile for further studies. These findings highlights the potential of PF3 as a novel anti-HIV-1 agent, necessitating further isolation and structural elucidation of active compounds. This is the first report of anti-HIV-1 activity from <em>Haloplegma duperreyi</em>, highlighting marine-derived natural products as promising candidates for new anti-HIV therapies. This study contributes significantly to the field of marine natural product-based antiviral research, emphasizing the importance of marine biodiversity and its contributions to the blue economy.</div></div>","PeriodicalId":7855,"journal":{"name":"Algal Research-Biomass Biofuels and Bioproducts","volume":"86 ","pages":"Article 103893"},"PeriodicalIF":4.6,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143144502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study investigated the distribution of LCPUFAs in glycerol backbones that form phospholipids and triacylglycerols (TAG) during cell growth. Integrated transcriptomic and lipidomic analyses were performed at different growth time points. LCPUFAs were associated with glycerol backbones after 12 h of phospholipid biosynthesis and synthesized TAGs at 72 h. In addition, the effects of different carbon sources (glucose, sugarcane molasses, and mixtures of each with glycerol) on growth and LCPUFA production were evaluated.

Gene expression analysis revealed upregulated expression of the fatty acid and phospholipid biosynthetic genes encoding acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), and lysophosphatidylcholine acyltransferase 2 (LPCAT2) at 6–12 h. In contrast, the expression of diacylglycerol acyltransferase (DGAT) for TAG biosynthesis was upregulated after 12 h in the sugarcane molasses medium.

Initially, locally available seaweeds along the Maharashtra coast were screened, followed by co-culture with <em>P. vannamei</em> with selected seaweed to evaluate production performance and physiological responses in zero-water exchange system.
