Antimitotic and cytotoxic flavonols from Zieridium pseudobtusifolium and Acronychia porteri.
Bioassay-guided fractionation of the extracts of Zieridium pseudobtusifolium and Acronychia porteri led to the isolation of 5,3'-dihydroxy-3,6,7,8,4'-pentamethoxyflavone [1], which showed activityExpand
Foveolins A and B, dammarane triterpenes from Aglaia foveolata.
Three known dammarane triterpenes, 3-epi-ocotillol, eichlerianic acid and shoreic acid, together with two new ones, foveolins A and B, have been isolated from the bark of Aglaia foveolata. StructuralExpand
Dammarane Triterpenes and Pregnane Steroids from Aglaia lawii and A. tomentosa
Three known dammaranes, cabraleone, eichlerianic acid and shoreic acid, together with two new ones, aglinins A and B, were isolated from the bark of Aglaia lawii. A. tomentosa also containedExpand
New nitrogenous and aromatic derivatives from Aglaia argentea and A. forbesii
Seeds and leaves of Aglaia argentea and bark of A. forbesii were extracted. The known cyclopentatetrahydrobenzofuran derivative rocaglaol (1) and the aminopyrrolidine odorine (5), were isolatedExpand
Apotirucallane Triterpenes from Aglaia argentea
Five new apotirucallane triterpenes were isolated from the seeds of Aglaia argentea : gentinones A (1), B (2), C (3), D (4), and gentinin (5). Their structures were established using spectroscopicExpand
Depsipeptides from Metarhizium anisopliae
Abstract From the culture medium of a strain of Metarhizium anisopliae , 14 depsipeptides have been isolated. Five of them were identified as known destruxins A, B, C, D and desmethyldestruxin B. TheExpand
A new peptide alkaloid from Discaria crenata
The structure of a new peptide alkaloid, crenatine A isolated from Discaria crenata, has been elucidated.
Tirucallane triterpenes from Dysoxylum macranthum
Abstract Eleven new tirucallane-type triterpenes, dymacrins A–K, were isolated from the bark of Dysoxylum macranthum together with two known tetracyclic triterpenes and two known pregnane steroids.Expand
Brominated indole alkaloids from the marine tunicate Pseudodistoma arborescens.
Chemical investigation of the cytotoxic CH2Cl2-soluble extract of the marine tunicate Pseudodistoma arborescens led to the isolation of four brominated indole alkaloids, arborescidines A [1], B [2],Expand
Piliostigmin, A 2-phenoxychromone, and C-methylflavonols from Piliostigma thonningii
Abstract Piliostigmin, a 2-phenoxychromone, and three C -methylflavonols, 6,8-di- C -methylquercetin 3-methyl ether, 6- C -methylquercetin 3,7-dimethyl ether and 6,8-di- C -methylquercetinExpand
