A New Eudesmane Sesquiterpene from Nigrospora oryzae, an Endophytic Fungus of Aquilaria sinensis
A new eudesmane-type sesquiterpene, 11-hydroxycapitulatin B (1), along with a known related sesquiterpene, capitulatin B (2), was isolated from the endophytic fungus Nigrospora oryzae A8 from Aquilaria sinensis, the only plant resource for agarwood production in China. This research demonstrates that the endophytic fungi from A. sinensis might play a role in the formation of agarwood.
متن کاملDehydrobrachylaenolide: an eudesmane-type sesquiterpene lactone
The three-ring eudesmanolide, C(15)H(16)O(3), is a natural product isolated from Dicoma anomala Sond. (Asteraceae). The compound contains an endo-exo cross conjugated methyl-enecyclo-hexenone ring with an envelope conformation trans-fused with cyclo-hexane and trans-annelated with an α-methyl-ene γ-lactone. The absolute structure was assigned by optical rotation measurements compared to those f...
متن کاملEudesmane-Type Sesquiterpene Glycosides from Dictamnus dasycarpus Turcz.
Eudesmane-type sesquiterpenes have been reported to exhibit varieties of biological activities. During the process of investigating this kind of natural product from the root bark of Dictamnus dasycarpus Turcz., 13 eudesmane-type sesquiterpene glycosides including six new isolates, named as dictameudesmnosides A₁ (1), A₂ (2), B (3), C (4), D (5), and E (6), together with seven known ones (7-13)...
متن کاملTwo new eudesmane alcohols from Jasonia glutinosa.
Two new sesquiterpene alcohols have been isolated from the aerial parts of Jasonia glutinosa D. C. The structure of these sesquiterpenes were characterized by 1D and 2D NMR techniques (DQCOSY. TOCSY, NOESY, HMQC and HMBC) as (11R)-eudesm-4-en-11,12-diol and (11R)-eudesmane-5alpha, 11,12-triol.
متن کاملA Concise Synthesis of the 1,6-Disubstituted Eudesmane Sesquiterpene Carbon Skeleton
The eudesmane sesquiterpenes are an important class of natural products, with relevant biological activities. Although these compounds can be substituted at practically all the carbon atoms, there is current interest for examples substituted at both C-1 and C-6 (see Schemes 1 and 2). In this short report we present a new methodology for the concise synthesis of the 1,6-disubstituted eudesmane c...
