Cembrane- and Casbane-Type Diterpenes from the South China Sea Soft Coral Sinularia nanolobata
Five new cembrane-type diterpenes (1–5), one new casbane-type diterpene (7), and ten known related ones (6, 8–16) were isolated from the South China Sea soft coral Sinularia nanolobata. The structures of new compounds were elucidated through comprehensive spectroscopic analysis, NMR calculation with DP4+ probability an...
