Abstract

Five new scalarane sesterterpenoids, felixins A-E (1-5), were isolated from the Formosan sponge Ircinia felix. The structures of scalaranes 1-5 were elucidated on the basis of spectroscopic analysis. Cytotoxicity of scalaranes 1-5 against the proliferation of a limited panel of tumor cell lines was evaluated.
