Scabrolides E-G, Three New Norditerpenoids from the Soft Coral Sinulariascabra.

摘要

Three new norditerpenoids, scabrolides E-G (1-3), and dissectolide A (4) have been isolated from the organic extract of a Taiwanese soft coral Sinularia scabra. The structures of 1-3 were determined on the basis of extensive spectroscopic analyses and by comparison of their spectral data with those of the known related metabolites. Metabolite 1 was found to exhibit significant cytotoxicity against the growth of Hepa59T/VGH and KB cell lines.
