Five New Diterpenoids from an Okinawan Soft Coral, Cespitularia sp.
Five new diterpenoids 1-5 were isolated from an Okinawan soft coral, Cespitularia sp., together with the known diterpenoid, alcyonolide (6). New diterpenoid structures were elucidated by spectroscopic methods and by comparison of their NMR data with those of related compounds. Alcyonolide (6) was cytotoxic against HCT 116 cells (IC₅₀ 5.85 μM), while these new diterpenoids 1-5 were much less act...
متن کاملChemistry and biology of Okinawan marine natural products*
Marine macroand micro-organisms collected in Okinawa are good sources of compounds with intriguing structures and interesting biological activities. Synthetic hybrid molecules of caffeine and eudistomin D from tunicates Eudistoma sp. were found to show better potency as adenosine receptor ligands than caffeine, and one of them exhibits potent activity for adenosine receptors tested, especially ...
متن کاملNew Casbane and Cembrane Diterpenoids from an Okinawan Soft Coral, Lobophytum sp.
A new rare casbane-type diterpenoid 1 and two new cembrane diterpenoids 2, 3 were isolated from an Okinawan soft coral, Lobophytum sp., together with four known cembrane diterpenoids 4-7. Their structures were elucidated by extensive analysis of spectroscopic data (1D and 2D NMR, IR, and MS) and a molecular modeling study. The new isolates showed weak anti-bacterial activity, mild cytotoxicity ...
متن کاملChemical Constituents and Biological Properties of the Marine Soft Coral Nephthea: A Review (Part 2)
This second part of the review dwells on Nephthea chabrolii and Nephthea Sp. which contain isoketochabrolic acid, ketochabrolic acid, sesquiterpenes, diterpenes and steroids. Corresponding biological activities such as anti-inflammatory and cytotoxic activities have also been observed for the isolated constituents. Most of the new compounds isolated from the genus Nephthea are from N. chabrolii...
متن کاملResponses of the soft coral Xenia elongata following acute exposure to a chemical dispersant
Limited toxicology data are available regarding oil dispersant exposure to coral species. Corexit® EC9500A (Corexit) is a commonly applied dispersant most well known for its use after the Deepwater Horizon spill in April, 2010. There is limited evidence that Corexit can cause a bleaching response in corals. The aims of the study were: (1) to determine the extent of bleaching after acute 24 h an...
