Secondary Metabolites from the Soft Coral Sinularia nanolobata
Soft coral Sinularia nanolobata was reported to contain xeniaphyllane-type diterpenoids, caryophyllane-type norsesquiterpenoids, and furanone derivative. An investigation on the chemical constituents of the coral Sinularia nanolobata collected at San-Shen-Tai has led to the isolation of six new compounds (1-6), including two novel skeletons (1 and 2), two new diterpenoids (3 and 4), and two new norsesquiterpenes (5 and 6). The structures of these compounds were determined on the basis of their spectroscopic analysis (1H NMR, 13C NMR, 1H-1H COSY, HSQC, HMBC, IR and HRESIMS) and their cytotoxic and antiviral activities were evaluated.
