Chemical investigation of the Taiwanese soft coral Asterospicularia laurae has led to the isolation of three new xenicane diterpenoids, named asterolaurins K-M (1-3, resp.). Their chemical structures were determined through extensive spectroscopic analyses ((1) H- and (13) C-NMR, (1) H,(1) H-COSY, HMBC, and NOESY). Compound 2 exhibited cytotoxic activity against HEp-2, Daoy, MCF-7, and WiDr tumor cells.
