Farnesides A and B, sesquiterpenoid nucleoside ethers from a marine-derived Streptomyces sp., strain CNT-372 from Fiji.

ABSTRACT: Farnesides A and B (1, 2), linear sesquiterpenoids connected by ether links to a ribose dihydrouracil nucleoside, were isolated from a marine-derived Streptomyces sp., strain CNT-372, grown in saline liquid culture. The structures of the new compounds were assigned by comprehensive spectroscopic analysis primarily involving 1D and 2D NMR analysis and by comparison of spectroscopic data to the recently reported ribose nucleoside JBIR-68 (3). The farnesides are only the second example of this exceedingly rare class of microbial terpenoid nucleoside metabolites. Farneside A (1) was found to have modest antimalarial activity against the parasite Plasmodium falciparum.

Antartin, a Cytotoxic Zizaane-Type Sesquiterpenoid from a Streptomyces sp. Isolated from an Antarctic Marine Sediment.

Project description:Antartin (1), a new zizaane-type sesquiterpene, was isolated from Streptomyces sp. SCO736. The chemical structure of 1 was assigned from the interpretation of 1D and 2D NMR in addition to mass spectrometric data. The relative stereochemistry of 1 was determined by analysis of NOE data, while the absolute stereochemistry was decided based on a comparison of experimental and calculated electronic circular dichroism (ECD) spectra. Antartin (1) showed cytotoxicity against A549, H1299, and U87 cancer cell lines by causing cell cycle arrest at the G1 phase.

Secondary metabolite chemistry of the marine-derived fungus Massarina sp., strain CNT-016.

Project description:Chemical investigation of the culture broth extracts of the marine-derived fungus Massarina sp. (strain CNT-016) has yielded two secondary metabolites, spiromassaritone (1) and massariphenone (2), as well as the previously reported fungal metabolites 6-epi-5'-hydroxy-mycosporulone (3) and enalin A (4). The structures of these compounds were established by a variety of one- and two-dimensional NMR experiments, while the relative configuration of spiromassaritone (1) was determined by X-ray crystallographic methods. The fungal strain was isolated as a sterile mycelium from an ocean mud sample and identified using ITS sequence analysis.

Complete Genome Sequence of the Marine-Derived Bacterium Streptomyces sp. Strain GMY02.

Project description:We report the complete genome sequence of Streptomyces sp. strain GMY02, isolated from Indonesian marine sediment. This bacterium has a circular 8,512,626-nucleotide chromosome. Genome mining analysis of the whole-genome sequence revealed that GMY02 has 28 biosynthetic gene clusters, dominated by genes encoding nonribosomal peptide synthetase and polyketide synthase.

Genome Sequence of Streptomyces sp. Strain HB-N217, Isolated from the Marine Sponge Forcepia sp.

Project description:The genome sequence of the Forcepia sponge-derived bacterium Streptomyces sp. strain HB-N217 was determined, with approximately 8.25?Mbp and a G+C content of 72.1%. Thirty biosynthetic gene clusters that bear the capability to produce secondary metabolites were predicted. The results will aid marine natural product chemistry and sponge-microbe association studies.

Draft genome sequence of the marine Streptomyces sp. strain PP-C42, isolated from the Baltic Sea.

Project description:Streptomyces, a branch of aerobic Gram-positive bacteria, represents the largest genus of actinobacteria. The streptomycetes are characterized by a complex secondary metabolism and produce over two-thirds of the clinically used natural antibiotics today. Here we report the draft genome sequence of a Streptomyces strain, PP-C42, isolated from the marine environment. A subset of unique genes and gene clusters for diverse secondary metabolites as well as antimicrobial peptides could be identified from the genome, showing great promise as a source for novel bioactive compounds.

Project description:Here, we report the draft genome sequence of Streptomyces sp. strain AA0539, isolated from marine sediment of the Yellow Sea, China. Its small genome (∼5.8 Mb) contains large, unique genes and gene clusters for diverse secondary metabolites, suggesting great potential as a source for the discovery of novel natural products.

Bioactive Polycyclic Quinones from Marine Streptomyces sp. 182SMLY.

Project description: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 proliferation of four different glioma cell lines with IC50 values in a range from 0.5 to 7.3 μM and induced apoptosis in the glioma cells. The ratios of IC50 for normal human astrocytes to IC50 for glioma cells were 6.4-53 for 1 and >14-31 for 2. N-acetyl-N-demethylmayamycin (1) also inhibited the growth of methicillin-resistant Staphylococcus aureus with MIC 20.0 μM.

Genome sequence of Streptomyces sp. strain Tu6071.

Project description:Streptomyces sp. Tü6071 is a soil-dwelling bacterium which has a highly active isoprenoid biosynthesis. Isoprenoids are important precursors for biopharmaceutical molecules such as antibiotics or anticancer agents, e.g., landomycin. Streptomyces sp. Tü6071 produces the industrially important terpene glycosides phenalinolactones, which have antibacterial activity against several Gram-positive bacteria. The availability of the genome sequence of Streptomyces sp. Tü6071 allows for understanding the biosynthesis of these pharmaceutical molecules and will facilitate rational genome modification to improve industrial use.

Chromomycin SA analogs from a marine-derived Streptomyces sp.

Project description:Two chromomycin SA analogs, chromomycin SA(3) and chromomycin SA(2), along with deacetylchromomycin A(3) and five previously reported chromomycin analogs were isolated from a marine-derived Streptomyces sp. The structures of the new compounds were determined by spectroscopic methods including 1D and 2D NMR techniques, HRMS and chemical methods. Chromomycin SA(3) and chromomycin SA(2) are the first naturally occuring chromomycin analogs with truncated side-chains. Biological evaluation of chromomycin analogs for cytotoxicity against two non-small cell lung cancer (NSCLC) cell-lines, A549 and HCC44, demonstrated a decrease in cytotoxicity for the truncated sides chain chromomycin analogs.
