A novel chlorinated norsesquiterpenoid and two related new metabolites from the soft coral Paralemnalia thyrsoides

Oxygenated Eremophilane- and Neolemnane-Derived Sesquiterpenoids from the Soft Coral Lemnalia philippinensis

“…A variety of sesquiterpenes related to eremophilane- and neolemnane-types, and others have been reported from the Taiwanese soft corals of the genera Lemnalia and Paralemnalia [3,4,5,6,7,8,9,10]. Our recent study of the chemical constituents of the Lanyu soft coral L .…”

Parathyrsoidins A–D, Four New Sesquiterpenoids from the Soft Coral Paralemnalia thyrsoides

“…Soft corals belonging to the genus Paralemnalia have been proved to be a rich source of sesquiterpenoids [1,2,3,4,5,6,7,8,9,10,11,12,13]. Our recent study of the chemical constituents of the soft coral P. thyrsoides has yielded a cytotoxic bisnorsesquiterpenoid, paralemnolide A [13].…”

Paralemnolide A, an Unprecedented Bisnorsesquiterpene from the Taiwanese Soft Coral Paralemnalia thyrsoides

“…Soft corals of the genus Paralemnalia [1,2,3,4,5,6,7,8] have been found to be rich sources of sesquiterpenoids of nardosinane [1,2,3], neolemnane [3,4] and africanane-type [3] compounds, as well as norsesquiterpenoids of nornardosinane-type [3,5,6] compounds. As part of the continuing search for bioactive substances from marine invertebrates, we explored the secondary metabolites of the soft coral Paralemnalia thyrsoides (Ehrenberg, 1934) which was collected from Sansiantai, Taitong County, Taiwan (Figure 1).…”
