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 کاملCyanohydrin Phosphonate Natural Product from Streptomyces regensis
Streptomyces regensis strain WC-3744 was identified as a potential phosphonic acid producer in a large-scale screen of microorganisms for the presence of the pepM gene, which encodes the key phosphonate biosynthetic enzyme phosphoenolpyruvate phosphonomutase. (31)P NMR revealed the presence of several unidentified phosphonates in spent medium after growth of S. regensis. These compounds were pu...

A new geldanamycin analogue from Streptomyces hygroscopicus.
A new geldanamycin analogue was isolated from Streptomyces hygroscopicus A070101. The structure was elucidated as 11-methoxy-17-formyl-17-demethoxy-18-O-21-O-dihydrogeldanamycin (1) on the basis of extensive 1D and 2D NMR as well as HRESI-MS spectroscopic data analysis. Compound 1 showed considerable cytotoxicity (SRB) against human cancer cell lines (breast cancer MCF-7, skin melanoma SK-MEL-2...
