Three New 2-pyranone Derivatives from Mangrove Endophytic Actinomycete Strain Nocardiopsis sp. A00203
نویسندگان
چکیده
Three new 2-pyranone derivatives, namely Norcardiatones A (1), B (2) and C (3), were isolated from the agar cultures of the strain Nocardiopsis sp. A00203, a mangrove endophytic actinomycete. Their structures were elucidated by spectroscopic and mass-spectrometric analyses, including 1D-, 2D-NMR and HR Q-TOFMS. Compound 1 showed week cytotoxicity against HeLa cells in MTT assay.

Background: Endophytic non-streptomycetes group of actinomycetes from Hibiscus rosasinensis leaves were screened for biosurfactant, polythene, plastic, and diesel biodegradation activities. Biosurfactant activity was evaluated by hemolysis, drop-collapsing test, lipase production, oil-spreading technique, bacterial adhesion to hydrocarbon (BATH) assay, penetration assay, and emulsification assa...
متن کاملDraft Genome Sequence of Marine-Derived Actinomycete Nocardiopsis sp. Strain TP-A0876, a Producer of Polyketide Pyrones
Here we report the draft genome sequence of Nocardiopsis sp. strain TP-A0876, isolated from marine sediment, which produces polyketide-derived pyrones called nocapyrones. The genome contains three polyketide synthase (PKS) gene clusters, one of which was proposed to be responsible for nocapyrone biosynthesis. This genome sequence will facilitate the study of the potential for secondary metaboli...

An alkaliphilic actinomycete strain, designated YIM 80379T, was isolated from a soil sample collected from the eastern desert of Egypt and subjected to polyphasic taxonomy. The strain produced substrate and aerial mycelia on different media, with an optimum pH for growth of 9.5-10 and scarce or no growth at pH 7. Strain YIM 80379T contained meso-diaminopimelic acid, no diagnostic sugars, type P...

Three new bianthraquinone derivatives, alterporriol K (1), L (2) and M (3), along with six known compounds were obtained from extracts of the endophytic fungus Alternaria sp. ZJ9-6B, isolated from the mangrove Aegiceras corniculatum collected in the South China Sea. Their structures were elucidated by one- and two-dimensional NMR spectroscopy, MS data analysis and circular dichroism measurement...
