Drimane-type sesquiterpenoids from the liverwort Makinoa crispata

Phytochemistry, 1989
Abstract Three new drimane-type sesquiterpenoids, 7α-chloro-6β-hydroxyconfertifoline, 6β,7α-dihydroxyconfertifoline and 6β,7β-epoxyconfertifoline were isolated from the liverwort Makinoa crispata together with the previously known eudesmane-type sesquiterpene lactone, crispatanolide and a sacculatane-type diterpene dialdehyde, perrottetianal A.

Seven drimane-type sesquiterpenoids from an earwig-associated Aspergillus sp.

Chinese Journal of Natural Medicines, 2023
Drimane-type sesquiterpenoids are widely distributed in fungi. From the ethyl acetate extract of the earwig-derived Aspergillus sp. NF2396, seven new drimane-type sesquiterpenoids, named drimanenoids A-G (1-7), were isolated. Their structures were elucidated by diverse spectroscopic analysis including high-resolution ESI-MS, one- and two-dimensional ...

A new drimane sesquiterpenoid glycoside from the seeds of Antiaris toxicaria

Journal of Asian Natural Products Research, 2011
A new drimane sesquiterpenoid glycoside, named 7-drimen-3β,11-diol 3-O-β-d-glucopyranoside, was isolated from the 95% EtOH extract of the seeds of Antiaris toxicaria (Pers.) Lesch. The chemical structure was completely elucidated using a combination of 1D and 2D NMR techniques (COSY, HMQC, HMBC, and ROESY) and HR-ESI-MS analysis.

Proversilins A–E, Drimane-Type Sesquiterpenoids from the Endophytic Aspergillus versicolor

Journal of Natural Products, 2020
Five new drimane-type sesquiterpenoids, named proversilins A-E (1-5), were isolated from the endophytic fungus Aspergillus versicolor F210 isolated from the bulbs of Lycoris radiata. Their structures and absolute configurations were characterized by extensive spectroscopic analysis, including 1D and 2D NMR and HRESIMS data, comparison of experimental ...

Drimane-type sesquiterpenoids from cultures of the fungus Xylaria polymorpha

Phytochemistry Letters, 2017
Abstract Three new drimane-type sesquiterpenoids named xylariaines A–C (1–3), together with one known analogue (4), were isolated from the ethyl acetate extract of cultures of the fungus Xylaria polymorpha (Pers.: Fr.) Grer. Their structures were elucidated unambiguously by NMR and single-crystal X-ray diffraction analysis.

Determination of the absolute configuration of a tetracyclic drimane sesquiterpenoid by Mosher's method

Tetrahedron: Asymmetry, 1994
Abstract The high field NMR application of the Mosher method has been successfully applied to determine the absolute configuration of a tetracyclic dihydroxydrimane derivative. The result indicates that highly functionalized drimanes from basidiomycetes correspond in their stereochemistry to (−)-drimenol.

Three new drimane sesquiterpenoids from cultures of the fungus Penicillium sp.

Journal of Asian Natural Products Research, 2016
Three new drimane sesquiterpenoids, 12-hydroxyalbrassitriol (1), drim-8(12)-en-6β,7α, 9α,11-tetraol (2), and drim-68(12)-dien-9α,11-diol (3), along with one known analog albrassitriol (4), were isolated from cultures of the tin mine tailings-associated fungus Penicillium sp.

Anti-inflammatory spiroaxane and drimane sesquiterpenoids from Talaromyces minioluteus (Penicillium minioluteum)

Bioorganic Chemistry, 2019
A new spiroaxane sesquiterpenoid talaminoid A (1) and two drimane sesquiterpenoid talaminoids B and C (2 and 3), together with four known compounds (4-7), were isolated from the solid culture broth of fungus Talaromyces minioluteum. The structures were determined by extensive 1D and 2D NMR and HRESIMS spectroscopic data analyses, and the absolute ...
