Bioactive Polycyclic Quinones from Marine Streptomyces sp. 182SMLY
Chemical investigation of the cultures of marine Streptomyces sp. 182SMLY led to the discovery of two new polycyclic anthraquinones, which were elucidated as N-acetyl-N-demethylmayamycin (1) and streptoanthraquinone A (2) based on the extensive spectroscopic analysis including 2D NMR, HRESIMS, and an electronic circular dichroism (ECD) calculation. Both anthraquinones remarkably suppressed the ...
متن کاملStudy on bioactive compounds from Streptomyces sp. ANU 6277.
An attempt was made to study the bioactive compounds from a terrestrial Streptomyces sp. ANU 6277 isolated from laterite soil. Four active fractions were recovered from the solvent extracts obtained from the culture broth of five day-old strain. Three bioactive compounds were purified and identified as 3-phenylpropionic acid, anthracene-9,10-quinone and 8-hydroxyquinoline. The components of the...
متن کاملExtraction and Identification of Antibacterial Secondary Metabolites From Marine Streptomyces sp. VITBRK2
Actinomycetes were isolated from marine sediment samples collected from the east coast of Chennai, Tamil Nadu, India. Well diffusion and agar plug methods were used for the evaluation of antibiotic production by these isolates against drug resistant Methicillin- resistant Staphylococcus aureus (MRSA) and vancomycin resistant Enterococci (VRE). The potential isolate VITBRK2 was mass cultured for...
متن کاملChalcomycins from Marine-Derived Streptomyces sp. and Their Antimicrobial Activities
Dihydrochalcomycin (1) and chalcomycin, (2), two known chalcomycins, and chalcomycin E (3), a new compound, were isolated from marine-derived Streptomyces sp. HK-2006-1. Their structures were elucidated by detailed spectroscopic and X-ray crystallographic analysis. The antimicrobial activities against Staphylococcus aureus, Escherichia coli, Candida albicans, and Aspergillus niger of 1-3 were e...
متن کاملAntioxidant 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...
