The Khamkhains, Neurotrophic Drimane-Type Sesquiterpenoids Derived from a Polyporaceous Basidiomycete Originating from Thailand. [PDF]

open access: yesJ Nat Prod
Eight unprecedented terpenoids were isolated from submerged cultures of a polyporoid basidiomycete originating from Thailand (which had been referred to as "Cerrena sp." in a previous publication) by preparative chromatography. Their chemical structures were elucidated by extensive two-dimensional nuclear magnetic resonance (NMR) spectroscopy and high ...

Chemical Diversity and Biosynthesis of Drimane‐Type Sesquiterpenes in the Fungal Kingdom

open access: yesChemBioChem, Volume 23, Issue 17, September 5, 2022., 2022
Fungal drimane‐type sesquiterpenes (DTSs) are emerging as a very interesting class of chemicals with many notable activities. Elucidation of DTS biosynthesis in fungi revealed that the two main precursors, drimenol and drim‐8‐ene‐11‐ol, are the preferred backbones.

Safety and Efficacy of Medicinal Plants Used to Manufacture Herbal Products with Regulatory Approval in Uganda: A Cross‐Sectional Study

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
Introduction. The Uganda National Drug Authority requires phytochemical screening, freedom from microbial contamination, and evidence of safety and efficacy of the constituent plants to register herbal products. Since Uganda has no pharmacopeia, safety, efficacy, and plant processing information are not readily available.

Seven New Drimane-Type Sesquiterpenoids from Cultures of Fungus Phellinus tuberculosus [PDF]

open access: yesNatural Products and Bioprospecting, 2014
Seven new drimane-type sesquiterpennoids, phellinuins A-G (1-7), together with one known compound 3β,11,12-trihydroxydrimene (8) were isolated from the cultures of mushroom Phellinus tuberculosus. Their structures were elucidated on the basis of NMR and MS spectroscopic data and by comparison with data reported in the literature.

Turbidite‐induced re‐oxygenation episodes of the sediment‐water interface in a diverticulum of the Tethys Ocean during the Oceanic Anoxic Event 1a: The French Vocontian Basin

open access: yesThe Depositional Record, Volume 6, Issue 2, Page 352-382, June 2020., 2020
The oceanic anoxic event OAE1a episode has been recorded in the Vocontian Basin (SE‐France) but recurrent reworking (turbidites) altered the record. Abstract Widespread anoxic events affected the Tethys Ocean during the Mesozoic. The Ocean Anoxic Event 1a (Early Aptian), expressed as the Selli Level or Goguel Level (GL) in European basins.
