title: More kapakahines from the marine sponge Cribrochalina olemda.
abstract: Three new kapakahines E-G (1-3) have been isolated from the marine sponge Cribrochalina olemda. Limited quantities of these compounds required not only NMR analysis but also FAB-MS/MS analysis for the structure elucidation. Kapakahine E showed cytotoxicity against P388 murine leukemia cells.
