Parathyrsoidins A–D, Four New Sesquiterpenoids from the Soft Coral Paralemnalia thyrsoides
Four new nardosinane-type sesquiterpenoids, parathyrsoidins A-D (1-4) were isolated from the soft coral Paralemnalia thyrsoides. The structures of parathyrsoidins A-D (1-4) were determined by extensive spectral analysis and their cytotoxicity against selected cancer cell lines as well as antiviral activity against human cytomegalovirus (HCMV) were evaluated in vitro.
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 کاملNew Cytotoxic Terpenoids from Soft Corals Nephthea chabroli and Paralemnalia thyrsoides
A novel cytotoxic diterpenoid, chabrolin A (1) (possessing an unprecedented terpenoid skeleton), as well as three new cytotoxic sesquiterpenoids, parathyrsoidins E-G (2-4), were isolated by cytotoxicity-guided fractionation from soft corals Nephtheachabroli and Paralemnalia thyrsoides. The structures of the new compounds were determined by extensive analysis of spectroscopic data.
متن کاملParalemnolide A, an Unprecedented Bisnorsesquiterpene from the Taiwanese Soft Coral Paralemnalia thyrsoides
Paralemnolide A (1), possessing an unprecedented bisnorsesquiterpene skeleton, was isolated from the soft coral Paralemnalia thyrsoides. The structure of paralemnolide A was elucidated by extensive analysis of spectroscopic data. The anti-HCMV (human cytomegalovirus) activity of 1 and its cytotoxicity against selected cell lines were evaluated.
متن کاملA new sesquiterpenoid hydroquinone from the marine sponge Dysidea arenaria.
Detailed chemical investigation of the South China sponge Dysidea arenaria resulted in the isolation of a new sesquiterpenoid hydroquinone, 19-hydroxypolyfibrospongol B (1), along with five known compounds: polyfibrospongol B (2), isosemnonorthoquinone (3), ilimaquinone (4), smenospongine (5) and smenotronic acid (6). The structures were determined by extensive spectroscopic analysis. The in vi...
