[Ab] Resumo:A bright-orange-pigmented, Gram-stain-negative, motile, and rod-shaped bacterium, strain MAA42 , was isolated from a marine sponge of the genus Haliclona, which is in long-time culture in a marine aquarium system at the Justus Liebig University Giessen, Germany. The strain grew at 4-34 °C (optimum 28 °C), in the presence of 0.5-9.5 % (w/v) NaCl (optimum 3.5 %) and at pH 4.5-10.0 (optimum pH 7.5). Strain MAA42 shared the highest 16S rRNA gene sequence similarity (98.1 %) with the type strain of Litorimonas taeanensis. Sequence similarities to all other closely related type strains were below 97 %. DNA-DNA hybridization of strain MAA42 with L. taeanensis DSM 22008 resulted in values of 4.7 % (reciprocal 17.7 %). Major cellular fatty acids of strain MAA42 were C18 : 1ω7c (66.2 %), C18 : 1 2-OH (17.4 %), and C18 : 0 (14.1 %). Spermidine was predominant in the polyamine pattern, and ubiquinone Q-10 was the major respiratory quinone. The polar lipid profile contained the major compounds phosphatidylglycerol, monoglycosyldiglyceride, three unidentified phospholipids, and one unidentified glycolipid. Glucuronopyranosyldiglyceride was present as a minor compound. The diagnostic diamino acid of the peptidoglycan was meso-diaminopimelic acid. The genomic DNA G+C content was 52.8 mol%. Based on the genotypic, chemotaxonomic, and phenotypic analyses, strain MAA42 represents a novel species of the genus Litorimonas, for which the name Litorimonas haliclonae is proposed. The type strain is MAA42 (=CCM 8709 =CIP 111178 =LMG 29765 ).

[Ab] Resumo:Three new dimeric 3-alkyl pyridinium alkaloids, named haliclocyclamines A-C (1-3), were isolated together with five known congeners, cyclostellettamines A (4), B (5), C (6), E (7), and F (8), from the Indonesian marine sponge Haliclona sp. The structures of 1-3 were assigned based on their spectroscopic data (1D and 2D NMR, HRFABMS, ESIMS/MS, UV, and IR). Compounds 1-8 exhibited antimicrobial activities against Mycobacterium smegmatis with inhibition zones of 17, 10, 13, 14, 8, 8, 12, and 12mm, respectively, at 10µg/disc. Compounds 3 and 8 also modestly inhibited the activity of vaccinia H-1-related phosphatase (VHR), a dual-specificity phosphatase, at 17-18µM.

[Ti] Título:Metabolic Profiling as a Screening Tool for Cytotoxic Compounds: Identification of 3-Alkyl Pyridine Alkaloids from Sponges Collected at a Shallow Water Hydrothermal Vent Site North of Iceland.

[Ab] Resumo:Twenty-eight sponge specimens were collected at a shallow water hydrothermal vent site north of Iceland. Extracts were prepared and tested in vitro for cytotoxic activity, and eight of them were shown to be cytotoxic. A mass spectrometry (MS)-based metabolomics approach was used to determine the chemical composition of the extracts. This analysis highlighted clear differences in the metabolomes of three sponge specimens, and all of them were identified as (Bowerbank, 1866). Therefore, these specimens were selected for further investigation. metabolomes contained a class of potential key compounds, the 3-alkyl pyridine alkaloids (3-APA) responsible for the cytotoxic activity of the fractions. Several 3-APA compounds were tentatively identified including haliclamines, cyclostellettamines, viscosalines and viscosamines. Among these compounds, cyclostellettamine P was tentatively identified for the first time by using ion mobility MS in time-aligned parallel (TAP) fragmentation mode. In this work, we show the potential of applying metabolomics strategies and in particular the utility of coupling ion mobility with MS for the molecular characterization of sponge specimens.

[Ti] Título:Sponge epizoism in the Caribbean and the discovery of new Plakortis and
Haliclona species, and polymorphism of Xestospongia deweerdtae (Porifera).

[Ab] Resumo:The new discovery by Vicente et al. (2014) of specialized epizoic symbioses between sponges of the genera Plakortis and Xestospongia revealed the obligate interaction of two new Plakortis spp. associating with Xestospongia deweerdtae and a new Xestospongia sp. In this study we formally describe the two new Plakortis spp. as Plakortis deweerdtaephila sp. nov. (previously reported as Plakortis sp. 1), Plakortis symbiotica sp. nov. (previously reported as Plakortis sp. 2) and describe the new Xestospongia sp. epibiont as Haliclona (Halichoclona) plakophila sp. nov.  Plakortis deweerdtaephila associates only with X. deweerdtae, and has very small to large straight diods (24.2-233.7 µm long) and triods (26.4-102.6 µm long) that form large ectosomal circular meshes (114-329 µm diameter). P. symbiotica associates with both X. deweerdtae and H. plakophila, has larger curved diods (71.9-141.8 µm long) and triods (20.4-70.6 µm long) that form smaller ectosomal circular meshes (43-121 µm diameter) than P. deweerdtaephila. Phylogenetic analysis of cox1 and cob gene fragments revealed a strongly supported clade that grouped both Plakortis spp. nov. distantly from any other known Plakortis spp. H. plakophila is described as a thin encrusting veneer of tissue with occasional papillae, so far only found associated with P. symbiotica in La Parguera, Puerto Rico. Phylogenetic analysis of 18S rRNA and cox1 gene fragments place it distantly from any known clade of Haplosclerida. We found a new associated morphotype of X. deweerdtae from Bocas del Toro Panama, which completely overgrew P. deweerdtaephila. In addition, free-living morphotypes from Panama produce larger S-shaped and round bracket shaped strongyles never before observed for this species, leading us to redescribe X. deweerdtae. All X. deweerdtae morphotypes shared >99% sequence homology of cox1, 18S rRNA and 28S rRNA genes with the holotype of X. deweerdtae. This study highlights the highly variable morphological characters of X. deweerdtae influenced by lifestyle and environmental factors. This is also the first time that an obligate symbiosis with a heterospecific sponge is used as a key taxonomic character.

[Ab] Resumo:The marine sponges and species, both of which are known to produce secondary bioactive metabolites, were used to extract 1304KO-327 and 1304KO-328. Such secondary metabolites are potentially antibacterial, antiviral, anti-inflammatory, antitumoral, antifungal, and antiplasmodial. In the present study, the effects of 1304KO-327 and 1304KO-328 were studied for their clinical and pathological importance. The cytotoxicity of 1304KO-327 and 1304KO-328 was assessed via MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay on HT-29, Caco-2, and Raw 264.7 cells. Rotavirus-infected Caco-2 cells were used to prove the antiviral effects of the marine sponge extracts. The test results cogently proved that the virus-inhibiting effects of the sponge extracts improved with extract concentration. Anti-inflammatory effects of the marine sponge extracts were tested on Lipopolysaccharide-treated Raw 264.7 cells. Nitric oxide and cytokine were produced by treatment of the cells with LPS and the inhibiting effects of the sponge extracts on IL-1ß formation were investigated. This study found that the NO production was decreased dose dependently, and IL-1ß formation was significantly reduced by the marine sponge extracts.

[Ab] Resumo:The first total synthesis of (±)-renieramycin I, which was isolated from the Indian bright blue sponge Haliclona cribricutis, is described. The key step is the selenium oxide oxidation of pentacyclic bis-p-quinone derivative (3) stereo- and regioselectively. We also report a large-scale synthesis of cribrostatin 4 (renieramycin H) via the C3-C4 double bond formation in an early stage based on the Avendaño's protocol, from readily available 1-acetyl-3-(3-methyl-2,4,5-trimethylphenyl)methyl-piperazine-2,5-dione (8) in 18 steps (8.3% overall yield). The synthesis provides unambiguous evidence supporting the original structure of renieramycin I.

[Ab] Resumo:Marine sponges (phylum Porifera) are well known to harbour a complex and diverse bacterial community. Some of these sponge-associated bacteria have been shown to be the real producers of secondary metabolites with a wide range of activities from antimicrobials to anticancer agents. Previously, we revealed that the strain Pseudomonas fluorescens H41 isolated from the sponge Haliclona sp. (collected at the coast of Rio de Janeiro, Brazil) showed a strong antimicrobial activity against clinical and marine bacteria. Thus, in this study the genes involved in the antimicrobial activity of P. fluorescens H41 were identified. To this end, a library of mutants was generated via miniTnphoA3 transposon mutagenesis and the resulting clones were characterized for their antimicrobial activity. It was demonstrated that genes involved in the biosynthesis of the pyoverdine siderophore are related to the inhibitory activity of P. fluorescens H41. Therefore, this strain might play an important role in the biocontrol of the host sponge.

[Ab] Resumo:Sponges are abundant, diverse and functionally important organisms of coral reef ecosystems. Sponge-associated microorganisms have been receiving greater attention because of their significant contribution to sponge biomass, biogeochemical cycles and biotechnological potentials. However, our understanding of the sponge microbiome is limited to a few species of sponges from restricted geographical locations. Here, we report for the first time the bacterial diversity of two cohabiting sponges, viz. Cinachyra cavernosa and Haliclona pigmentifera, as well as that in the ambient water from the coral reef ecosystems of the Gulf of Mannar, located along the southeast coast of India. Two hundred and fifty two clones in the 16S rRNA gene library of these sponges were grouped into eight distinct phyla, of which four belonged to the core group that are associated only with sponges. Phylogenetic analysis of the core bacteria showed close affinity to other sponge-associated bacteria from different geographical locations. γ-Proteobacteria, Chloroflexi, Planctomycetes and Deferribacter were the core groups in C. cavernosa while ß and δ-Proteobacteria performed this role in H. pigmentifera. We observed greater OTU diversity for C. cavernosa (HÇ€ 2.07) compared to H. pigmentifera (HÇ€ 1.97). UniFrac analysis confirmed the difference in bacterial diversity of the two sponge species and also between the sponges and the reef water (p<0.001). The results of our study restate the existence of a host driven force in shaping the sponge microbiome.
