Dataset Information

Seaweed metabolite database (SWMD): A database of natural compounds from marine algae.

ABSTRACT:

Unlabelled

The cataloguing of marine chemicals is a fundamental aspect for bioprospecting. This has applications in the development of drugs from marine sources. A publicly accessible database that provides comprehensive information about these compounds is therefore helpful. The Seaweed Metabolite Database (SWMD) is designed to provide information about the known compounds and their biological activity described in the literature. Geographical origin of the seaweed, extraction method and the chemical descriptors of each the compounds are recorded to enable effective chemo-informatics analysis. Crosslinks to other databases are also introduced to facilitate the access of information about 3D Structure by X-ray and NMR activity, drug properties and related literature for each compound. This database currently contains entries for 517 compounds encompassing 25 descriptive fields mostly from the Red algae of the genus Laurencia (Ceramiales, Rhodomelaceae). The customized search engine of this database will enable wildcard querying, which includes Accession Number, Compound type, Seaweed Binomial name, IUPAC name, SMILES notation or InChI.

Project description:The intestine and skin provide crucial protection against the external environment. Strengthening the epithelial barrier function of these organs is critical for maintaining homeostasis against inflammatory stimuli. Recent studies suggest that polar marine algae are a promising bioactive resource because of their adaptation to extreme environments. To investigate the bioactive properties of polar marine algae on epithelial cells of the intestine and skin, we created extracts of the Antarctic macroalgae Himantothallus grandifolius, Plocamium cartilagineum, Phaeurus antarcticus, and Kallymenia antarctica, analyzed the compound profiles of the extracts using gas chromatography-mass spectrometry, and tested the protective activities of the extracts on human intestinal and keratinocyte cell lines by measuring cell viability and reactive oxygen species scavenging. In addition, we assessed immune responses modulated by the extracts by real-time polymerase chain reaction, and we monitored the barrier-protective activities of the extracts on intestinal and keratinocyte cell lines by measuring transepithelial electrical resistance and fluorescence-labeled dextran flux, respectively. We identified bioactive compounds, including several fatty acids and lipid compounds, in the extracts, and found that the extracts perform antioxidant activities that remove intracellular reactive oxygen species and scavenge specific radicals. Furthermore, the Antarctic marine algae extracts increased cell viability, protected cells against inflammatory stimulation, and increased the barrier integrity of cells damaged by lipopolysaccharide or ultraviolet radiation. These results suggest that Antarctic marine algae have optimized their composition for polar environments, and furthermore, that the bioactive properties of compounds produced by Antarctic marine algae can potentially be used to develop therapeutics to promote the protective barrier function of the intestine and skin.
