Integrating LC-MS/MS molecular networking and bioassay-guided fractionation enabled the targeted isolation of a new bioactive cyclic octapeptide, samoamide A (1), from sample cf. Symploca sp. collected in American Samoa. The structure 1 was established by detailed 1D 2D NMR experiments, HRESIMS data, chemical degradation/chromatographic (e.g., Marfey's analysis) studies. Pure compound shown to have vitro cytotoxic activity against several human cancer cell lines both traditional culture zone...
Eugenia pyriformis Cambess., known as uvaia, is a species of Myrtaceae native to Brazil. Its leaves are used in folk medicine treat gout because they possess the property inhibiting xanthine oxidase, an enzyme involved conversion into uric acid. The objective this work was study leaf and stem morpho-anatomy E. pyriformis, order contribute what about Brazilian flora, medicinal plant potential vegetal drug. Samples mature young stems were fixed sectioned by freehand, or embedded glycol...
The Eugenia pyriformis Cambess. species, Myrtaceae, also known by the popular name as uvaia was evaluated for its antimicrobial activity. Broth microdilution method used to determine Minimum Inhibitory Concentration (MIC) against selected pathogenic strains of bacteria, and fungi. Checkerboard evaluate synergistic interactions E. with Vancomycin Fluconazole. leaf stem crude extract showed Gram-positive MIC values 125 250 µg/ml leveduriform fungi ranging from 7.81 62.5 µg/ml. Ethyl acetate,...
Molecular networking (MN) can efficiently dereplicate extracts and pure compounds. Red algae of the genus Laurencia are rich in halogenated secondary metabolites, mainly sesquiterpenes C15-acetogenins. Brown Dictyopteris produce C11-hydrocarbons, sulfur-containing compounds, while Dictyota Canistrocarpus reported to contain diterpenes. This study performs an exploratory MN analysis 14 from collected Brazil (including oceanic islands) characterizes metabolites analyzed species. The some...
A recent untargeted metabolomics investigation into the chemical profile of 10 organic extracts from cf. Symploca spp. revealed several interesting leads for further natural product drug discovery. Subsequent target-directed isolation efforts with one these, a Panamanian marine cyanobacterium sp., yielded phenethylamide metabolite that terminates in relatively rare gem-dichlorovinylidene moiety, caracolamide (1), along known isotactic polymethoxy-1-alkene (2). Detailed NMR and HRESIMS...
Phylogenetic analysis of complete cytochrome-b, 12S-rRNA, and protamine-Pl gene sequences from 17 the 18 extant species Phascogalinae (Marsupialia: Dasyuridae) suggests relationships that are strikingly congruent with previous morphological molecular studies. Australian New Guinean members Antechinus comprise separate monophyletic groups, latter includes both genus Murexia. Among species, two clades recovered high resolution: A. swainsonii minimus; leo, bellus, flavipes. Affinities stuartii,...
Abstract The order Sapindales is comprised of nine families and in Brazil it represented by six, including Rutaceae Juss., which constitutes the largest group this order. A variety species Zanthoxylum L. are distributed throughout country, among them kleinii (R.S. Cowan) P.G. Waterman, found states Brazil. This study aimed to characterize morphoanatomy leaf, petiole, rachis, stem Z. . Histochemical tests were performed, sections visualized under optical scanning electron microscopy. analysis...
Marine cyanobacteria have emerged as a source of promising bioactive compounds. The isolation strains from tropical environments seems to be an important step in the search for molecules displaying bioactivity, besides being valuable biotechnological purposes. Thus, objective present study was describe marine cyanobacterial strains, isolated and characterized terms morphology molecular phylogeny, well screened biologically active Five were morphologically Leptolyngbya (CENA553, CENA554...
Abstract Aconitum napellus L. is a popular medicinal plant extensively used in homeopathy. This article provides detailed morphology and microscopy, including the anatomical histochemical features of herb, to aid authentication quality control. In cross‐section, root secondary growth shows phloem surrounded by pericyclic fibers well‐developed xylem. The stem irregular outline, displaying unicellular trichomes many free collateral vascular bundles encircling pith. leaf dorsiventral,...
Abstract Kittiwake was discovered by well 21/18-2 within a 7th Round block, part of Production Licence P351. Highly undersaturated oil is present in the Fulmar Formation and Skagerrak reservoir sequences; 70 MMBBL reserves sandstones whereas mostly immovable. The field will be developed from single 16-slot platform with initially 5 producing water-injection wells. Solution gas removed via Field pipeline to St Fergus and, as September 1990, loaded onto tankers single-buoy mooring.
HIGHLIGHTS Eugenia pyriformis essential oil (EO) of the leaf contains linalol, terpinen-4-ol; 2-carene; The extract showed β-amiryn (1) and porphyrin derivatives; extracts stem antioxidant activity; hexane allelopathic activity.
