چکیده
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 computational approaches.

Cytotoxic C(35) terpenoid cryptotrione from the bark of Cryptomeria japonica.
A novel C(35)-terpene, designated as cryptotrione (1), with an unprecedented skeleton possessing an abietane diterpene with a unique bicyclic sesquiterpene, is identified from the bark of Cryptomeria japonica. The carbon skeleton of 1 represents a new structural entity, and this is an intriguing addition to the structurally diverse diterpene-sesquiterpene class. A unique biosynthetic pathway is...
متن کاملAntitumour activities of sesquiterpene lactones from Inula helenium and Inula japonica.
Eight sesquiterpene lactones were isolated from the roots of Inula helenium and flowers of I. japonica. Among them, isoalantolactone (3) and santamarine (6) exhibited significant growth inhibitory activities against gynecologic cancer cell lines, while others weakly inhibited the growth of the cell lines (IC50 < or = 100 microM). In addition, 3 significantly inhibited the tumour growth of S180 ...

Root extracts of Holostylis reniformis (Aristolochiaceae) yielded three new natural sesquiterpenes, a sesquiterpene with an unusual carbon skeleton, 4,5-seco-guaiane (7-epi-11-hydroxychabrolidione A, 1), a nine-membered lactone with new carbon skeleton (holostylactone, 2), and a new megastigmane [(6S,7E)-6,9-dihydroxy-10-(2'-hydroxy-ethoxy)-4,7-megastigmadien-3-one, 3], together with bulnesol a...
متن کاملSemisynthesis, an Anti-Inflammatory Effect of Derivatives of 1β-Hydroxy Alantolactone from Inula britannica.
1β-hydroxy alantolactone, a sesquiterpene lactone mainly isolated from Inula genus plants, exhibits potent anti-inflammatory and anticancer activities. In this work, 1β-hydroxy alantolactone was isolated and five derivatives were prepared through different reactions at the C1-OH and C13-methylene motifs. The structure-activity relationships (SAR) of anti-inflammatory effects against NO producti...
متن کاملCorianin from Coriaria japonica A. Gray, and sesquiterpene lactones from Loranthus parasiticus Merr. used for treatment of schizophrenia.
Pseudotutin previously isolated from Coriaria japonica A. GRAY was revealed to be a molecular compound consisting of equimolar tutin (2) and a new related sesquiterpene lactone, corianin (3). Corianin was also isolated together with coriamyrtin (1), tutin (2) and coriatin (4), from Loranthus parasiticus MERR., a parasitic plant that grows on the twigs of Coriaria sinica MAXIM. The structure of ...
