AI Article Synopsis

  • - Six new terpenoid compounds were discovered from a marine fungus, including three labdane-type diterpenes (talaroterpenoids A-C) and three meroterpenoids (talaroterpenoids D-F), along with five known compounds.
  • - Their chemical structures were determined using various advanced techniques like NMR, high-resolution mass spectrometry, and crystallography.
  • - Some of the new compounds demonstrated inhibitory effects on nitric oxide release in specific brain cells, while one showed moderate antifungal properties against certain fungi.

Article Abstract

Six new highly oxidized -terpenoids, including three 3--labdane type diterpenes, talaroterpenoids A-C (-), and three meroterpenoids containing an orthoester group, talaroterpenoids D-F (-), together with five known compounds (- and -), were isolated from the marine-derived fungus . Their chemical structures were elucidated through 1D, 2D NMR, HRESIMS, -based configuration analysis (JBCA), computational ECD calculations, and single-crystal X-ray diffraction analysis. Compounds and contain an unusual 6,20--lactone-bridged scaffold. Compounds and presented inhibitory effects on NO release in lipopolysaccharide (LPS)-induced BV-2 cells with IC values of 11.47 and 11.32 μM, respectively. Talaroterpenoid C () showed moderate antifungal activity against and Steyaert.

The fungal genus Fusarium is a treasure-trove of structurally diverse secondary metabolites, contributed greatly by marine-derived strains. A new cedrane sesquiterpene, fusacedrol (1), and a new fusarin member, fusarin M (2), were isolated from F. graminearum 12Ⅱ2N that was isolated as an endophyte from the marine brown alga Sargassum sp.

This study investigated the fatty acids (FA) profile of 54 actinomycete strains isolated from marine sediments collected off the Portugal continental coast, specifically from the Estremadura Spur pockmarks field, by GC/MS. Fatty acid methyl esters (FAMEs) were prepared from the ethyl acetate lipidic extracts of these strains and analyzed by gas chromatography-mass spectrometry (GC/MS), with FA identification performed using the NIST library. The identified FAs varied from C12:0 to C20:0, where 32 distinct FAs were identified, including 7 branched-chain fatty acids (BCFAs), 9 odd-chain fatty acids (OCFAs), 8 monounsaturated fatty acids (MUFAs), 6 saturated fatty acids (SFAs), 1 polyunsaturated fatty acid (PUFA), and 1 cyclic chain fatty acid (CCFA).
