Sinularia nanolobata

A few other amphilectane derivatives, not glycosylated and lacking an aromatic nucleus, have been isolated from the alcyonacean Sinularia nanolobata, also harvested in Japan. Sinulobatins are cytotoxic to L1210 and KB cells with ICso values between 3.0 and 7.7 xgml . ... 

Aquariolides A-C are a new class of tricyclic diterpenes isolated from the gorgonian Erythropodium caribaeorum, first cultivated in an aquarium then harvested in the wild in the Dominican Republic. This original C5/C5/C9 skeleton is formed from briarane and erythrane carbon skeletons by di-Jt-methane and vinylcyclopropane rearrangements. No biological property seems to have been reported (Taglialatela-Scafati et al., 2002, 2003). Sinulobatin D is a rare tetracyclic diterpene discovered in Sinularia nanolobata, harvested in Japan.
