Dehydrobrachylaenolide: an eudesmane-type sesquiterpene lactone
نویسندگان
چکیده
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 from the synthetic compound with known stereochemistry. The crystal packing is consolidated by C-H⋯O interactions.

Neojaponicone A, a bioactive sesquiterpene lactone dimer with an unprecedented carbon skeleton from Inula japonica.
Five new dimeric sesquiterpene lactones, neojaponicone A (1) and japonicones M-P (2-5) were isolated from the aerial part of Inula japonica. Neojaponicone A (1) has an unprecedented carbon skeleton with an unusual valerolactone system formed between a guaianolide and an eudesmane. The structure and absolute configuration of 1 were established by extensive analysis of spectroscopic data and comp...
متن کاملAlantolactone selectively ablates acute myeloid leukemia stem and progenitor cells
BACKGROUND The poor outcomes for patients diagnosed with acute myeloid leukemia (AML) are largely attributed to leukemia stem cells (LSCs) which are difficult to eliminate with conventional therapy and responsible for relapse. Thus, new therapeutic strategies which could selectively target LSCs in clinical leukemia treatment and avoid drug resistance are urgently needed. However, only a few sma...
متن کاملA 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.

Six new germacranolides, zawadskinolides A-F (1-6), and a new eudesmane glucoside, chrysantiloboside (7) were isolated from the aerial parts of Dendranthema zawadskii var. latilobum, along with thirteen known constituents. Their structures were elucidated by means of spectroscopic evidence. Bioassay showed that flavonoids such as apigenin (9), (-)-eriodictyol (10) and nepetin (12), as well as t...
