Antioxidant and cytotoxic activities of metabolites produced by a new marine Streptomyces sp. isolated from the sea cucumber Holothuria leucospilota
Marine microorganisms are important sources for novel natural products. Hence, the aim of this study was introducing the marine microorganisms with capability to produce antioxidant and cytotoxic metabolites. For this purpose, ten live sea cucumbers (Holothuria leucospilota) were collected from Larak Island. Then, their intestine contents were serially diluted and treated by heating (55 °c). 10...

متن کاملAntifungal active triterpene glycosides from sea cucumber Holothuria scabra.
To study the new antifungal active triterpene glycosides of sea cucumber Holothuria scabra. Triterpene glycosides from Holothuria scabra were separated and purified by silica gel chromatography, reversed-phase silica gel chromatography and RP-HPLC. Their structures were elucidated on the basis of spectral data and chemical evidence. Three triterpene glycosides were identified as scabraside A (1...

Aquatics are a source of bioactive compounds that these compounds have different properties such as antimicrobial activity. In this study, antibacterial activity of methanol, chloroform and hexane extracts from body wall, gonad and intestine of sea cucumber Holothuria leucospilota was evaluated against Bacillus subtilis, Pseudomonas aeruginosa and Staphylococcus aureus. Bioactive compounds of b...
متن کاملBioactive sulfated saponins from sea cucumber Holothuria moebii.
The bioactive ingredients of sea cucumber Holothuria moebii were investigated, and four sulfated saponins (1-4) and one desulfated saponin (3B) with an unusual 3,4-epoxy xylose were obtained from this study. Compound 2 is a new triterpenoid saponin and 3B is a new artificial compound. On the basis of the extensive NMR and HRESIMS data, their structures were assigned as 3-O-[β-D-quinovopyranosyl...
