The structures of cespitularins A-H (1-8) were elucidated by 1D and 2D NMR spectral-analysis, and their cytotoxicity against selected cancer cells was measured in vitro.[SDGs]SDG3[SDGs]SDG14cespitularin a; cespitularin b; cespitularin c; cespitularin d; diterpene; terpenoid; unclassified drug; article; carbon nuclear magnetic resonance; coral; cytotoxicity; drug isolation; fractionation; leukemia cell; structure analysis; Animals; Anthozoa; Antineoplastic Agents; Diterpenes; Drug Screening Assays, Antitumor; Molecular Structure; Spectrum Analysis; Tumor Cells, Cultured; Alcyonacea; Anthozoajournal article10.1021/np020077w2-s2.0-0036772613WOS:000178935100008
