The chemical study of the gorgonian Lophogorgia peruana collected at the Gulf of California has led to the isolationof the new diterpenes lophodienone (2), lophodiol A (3), lophodiol B (4), 17-acetoxylophotoxin (5), 15,16-epoxylophotoxin(6), 17-acetoxy-15,16-epoxylophotoxin (7), and isoepoxylophodione (8), together with the known compounds lophotoxin(1), rubifolide (9), lopholide (10), deoxylophotoxin (11), and the lophotoxin analogues 12 and 13. The structures of thenew metabolites have been established by spectroscopic techniques and chemical correlation. The in vitro cytotoxicityhas been tested against three tumor cell lines.
