摘要
Aurantosides G-I (1-3) have been isolated from the lithistid sponge Theonella swinhoei from Papua New Guinea. Their structures were established by spectroscopic and chemical methods. Compounds 1-3 represent new monochloropentaenoyl tetramic acids with mono-, di-, and tri-N-saccharide substituents, respectively. Aurantosides G-I (1 -3) failed to show any significant cytotoxicity against the human colon tumor cell line HCT-116.
