Nardosinane sesquiterpenoids from the Formosan soft coral Lemnalia flava.
Four new nardosinane-type sesquiterpenoids, flavalins A-D (1-4), have been isolated from the Formosan soft coral Lemnalia flava. The structures of the new metabolites were determined by extensive spectroscopic analysis, and the structure of 2 was confirmed by X-ray diffraction analysis. A plausible biosynthetic pathway to 1 and 2 is proposed. Compound 1 was found to display dose-dependent inhib...
متن کاملOxygenated Ylangene-Derived Sesquiterpenoids from the Soft Coral Lemnalia philippinensis
Chemical examination of a Taiwanese soft coral Lemnalia philippinensis led to the isolation of three oxygenated ylangene-derived sesquiterpenoids 1-3, including two new metabolites, philippinlins A and B (1 and 2). The structures of these compounds were elucidated on the basis of detailed spectroscopic data. Compound 1 was shown to exhibit cytotoxicity against HepG2, MDA-MB231 and A549 cancer c...
متن کاملNardosinane-Type Sesquiterpenoids from the Formosan Soft Coral Paralemnalia thyrsoides
Five new nardosinane-type sesquiterpenoids, paralemnolins Q-U (1-5), along with three known compounds (6-8), were isolated from the Formosan soft coral Paralemnalia thyrsoides. The structures of new metabolites were elucidated on the basis of extensive spectroscopic methods, and the absolute configuration of 1 was determined by the application of Mosher's method on 1. Among these metabolites, 1...
متن کاملOxygenated Eremophilane- and Neolemnane-Derived Sesquiterpenoids from the Soft Coral Lemnalia philippinensis
Five sesquiterpene-related metabolites (1-5), including two new eremophilane-type compounds, philippinlins C and D (1 and 2) and a 4,5-seconeolemnane philippinlin E (3), were isolated from the organic extract of a Taiwanese soft coral Lemnalia philippinensis. The structures of the new metabolites were determined on the basis of extensive spectroscopic analysis and by comparison of NMR data with...
متن کاملNew cadinene sesquiterpenoids from the Formosan soft coral Xenia puerto-galerae.
Six new cadinene sesquiterpenoids, xenitorins A-F (1-6), were isolated from the methylene chloride solubles of the Formosan soft coral Xenia puerto-galerae. The structures were elucidated by 1D and 2D NMR spectral analysis, and their cytotoxicity against selected cancer cells was measured in vitro.
