Two new 24-homoscalarane sesterterpenoids, felixins F (1
) and G (2
), were isolated from the sponge Ircinia felix
. The structures of new homoscalaranes 1
were elucidated by extensive spectroscopic methods, particularly with one-dimensional (1D) and two-dimensional (2D) NMR, and, by comparison, the spectral data with those of known analogues. The cytotoxicity of 1
against the proliferation of a limited panel of tumor cell lines was evaluated and 1
was found to show cytotoxicity toward the leukemia K562, MOLT-4, and SUP-T1 cells (IC50
≤ 5.0 μM).
