More kapakahines from the marine sponge Cribrochalina olemda

Org Lett. 2003 May 1;5(9):1387-90. doi: 10.1021/ol026830u.

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.
