Seven novel diterpenoids pachyclavulariolides G-L (1-6), secopachyclavulariaenone, A (7) along with two known compounds, pachyclavulariolide (8) and pachyclavulariolide E (9) have been isolated from the soft coral Pachyclavularia violacea. The structures of 1-6 were established by spectroscopic and chemical methods along with extensive single crystal X-ray analyses. The structure of 8 was further confirmed and the relative configuration of 9 was fully established also by X-ray structure analyses. Cytotoxicity of these compounds toward various cancer cell lines also is described. (C) 2001 Elsevier Science Ltd. All rights reserved.
