Two new sesquiterpenes from Chloranthus japonicus Sieb.[Pubmed:27399937]
Nat Prod Res. 2016 Nov;30(21):2476-82.
Two new sesquiterpenes, namely, 1beta,10beta-dihydroxy-eremophil-7(11), 8-dien-12,8-olide (1) and 8,12-epoxy-1beta-hydroxyeudesm-3,7,11-trien-9-one (2), together with three known sesquiterpenoids, shizukolidol (3), 4alpha-hydroxy-5alpha(H)-8beta-methoxy-eudesm-7(11)-en-12,8-olide (4), and neolitacumone B (5), and two known monoterpenes, (3R,4S,6R)-p-menth-1-en-3,6-diol (6) and (R)-p-menth-1-en-4,7-diol (7), were isolated from the whole plant of Chloranthus japonicus Sieb. Their structures were elucidated on the basis of spectroscopic data analysis and comparison with those of related known compounds. Compounds 4-7 were isolated from this plant for the first time.
Sesquiterpenoids from Chloranthus henryi and their anti-neuroinflammatory activities.[Pubmed:24934677]
Chem Biodivers. 2014 Jun;11(6):919-28.
Five new and seven known mono-sesquiterpenoids (1-5 and 6-12, resp.) together with five known lindenane-type disesquiterpenoids, 13-17, were isolated from the whole plant of Chloranthus henryi. Based on spectroscopic methods, the new structures were established to be (5S,6R,8S,10R)-6-hydroxyeudesma-4(15),7(11)-diene-12,8-olide (1), 6alpha-hydroxyeudesma-4(15),7(11),8(9)-triene-12,8-olide (2), 8,12-epoxy-1beta-hydroxyeudesma-4(15),7,11-trien-6-one (3), 12-oxochloraniolide A (4), and (4alpha)-8-hydroxy-12-norcardina-6,8,10-trien-11-one (5), respectively. Among the isolates, compound 2, zederone epoxide (8), spicachlorantin G (13), chloramultilide A (14), shizukaol B (15), and spicachlorantin B (17) showed significant anti-neuroinflammatory effects by inhibiting nitric-oxide (NO) production in lipopolysaccharide (LPS)-stimulated murine BV-2 microglial cells with relatively low cytotoxicity.
DNA Topoisomerase Inhibitory Activity of Constituents from the Flowers of Inula japonica.[Pubmed:26936053]
Chem Pharm Bull (Tokyo). 2016;64(3):276-81.
Fourteen compounds were isolated from the flowers of Inula japonica THUNB. (Asteraceae), including two new compounds, (1S,2S,4S,5S,8S,10R)-2-acetoxy-4,3-dihydroxy-pseudoguai-7(11)-en-12,8-olide (1) and (1S,2S,4S,5S,8S,10R)-2,4,13-trihydroxy-pseudoguai-7(11)-en-12,8-olide (2), and twelve known compounds, budlein B (3), 6beta-hydroxytomentosin (4), 6-deacetoxybritanin (5), 4-epipulchellin (6), britanin (7), tomentosin (8), (+)-dihydroquercetin (9), (-)-syringaresinol (10), quercetagetin 3,4'-dimethyl ether (11), luteolin (12), britanin G (13) and inuchinenolide C (14). Structures of 1 and 2 were determined based on one and two dimensional (1D)- and (2D)-NMR data and Mosher's esterification method. Compounds 9 and 12 showed inhibitory activities toward DNA topoisomerase I with IC50 values of 55.7 and 37.0 microM, respectively, compared to camptothecin (CPT) with an IC50 of 24.5 microM. Compounds 7-9 and 11-14 exhibited more potent inhibitory activity against topoisomerases II with IC50 values of 6.9, 3.8, 3.0, 6.9, 10.0, 14.7 and 13.8 microM, respectively, than that of etoposide (VP-16) with an IC50 of 26.9 microM. Compounds 4-7 and 10-14 exhibited weak cytotoxicities to the selected cancer cell lines.
[Chemical constituents from roots of Ligularia intermedia].[Pubmed:26087552]
Zhongguo Zhong Yao Za Zhi. 2015 Mar;40(5):894-6.
A new sesquiterpenoid, 8alpha-hydroxy-6beta-methoxy-1-oxoeremophila-7 (11), 9 (10) -diene-12, 8-olide (1) and five known compounds, petasin (2), caffeic acid (3), hepta-cosanol (4), beta-sitosterol (5) and beta-daucosterol (6) have been isolated from the roots of Ligularia intermedia. The compounds were isolated by column chromatography on silica gel and Sephadex LH-20, and identified based on spectral analyses (MS, 1H-NMR, 13C-NMR).
New 12,8-Eudesmanolides from Eutypella sp. 1-15.[Pubmed:28951605]
J Antibiot (Tokyo). 2017 Oct;70(10):1029-1032.
Four new 12,8-Eudesmanolides (1-4) and one known compound 5 named 13-Hydroxy-3,7(11)-eudesmadien-12,8-olide, were isolated from a mangrove rhizosphere-derived fungus Eutypella sp. 1-15. Their structures with absolute stereochemistry were determined by the comprehensive spectroscopic data, experimental and calculated ECD analysis. Compound 1 exhibited potent anticancer activity against JEKO-1 and HepG2 with IC50 values of 8.4 and 28.5 muM, respectively. Additionally, compound 1 also showed moderate antimicrobial activity.
