The structures of compounds 1-6 were determined by 1D and 2D spectral analysis, and their cytotoxicity against selected cancer cells was measured in vitro.[SDGs]SDG33 hydroxydolabella 4(16),7,11(12) triene 3,13 dione; 7 hydroperoxydolabella 4(16),8(17),11(12) triene 3,13 dione; antineoplastic agent; cytotoxic agent; diterpene; dolabella 4(16),10 diene 7,8 epoxy 3,13 dione; dolabella 4(16),7 diene 10,11 epoxy 3,13 dione; dolabella 4(16),7,10 triene 3,13 dione; dolabella 4(16),7,11(12) triene 3,13 dione; unclassified drug; article; carbon nuclear magnetic resonance; coral; cytotoxicity; drug isolation; drug structure; human; human cell; proton nuclear magnetic resonance; spectroscopy; structure analysis; Animals; Antineoplastic Agents; Carcinoma, Squamous Cell; Cnidaria; Diterpenes; Humans; Leukemia P388; Lung Neoplasms; Magnetic Resonance Spectroscopy; Mass Spectrometry; Mice; Molecular Structure; Spectrophotometry, Infrared; Spectrophotometry, Ultraviolet; Stereoisomerism; Taiwan; Tumor Cells, Cultured; Alcyonacea; Anthozoa; Clavularia; Dolabella; InvertebrataCytotoxic dolabellane diterpenes from the Formosan soft coral Clavularia inflatajournal article10.1021/np010106n2-s2.0-0034861473WOS:000170658400007
