New Cytotoxic 24-Homoscalarane Sesterterpenoids from the Sponge Ircinia felix

Two new 24-homoscalarane sesterterpenoids, felixins F (1) and G (2), were isolated from the sponge Ircinia felix. The structures of new homoscalaranes 1 and 2 were elucidated by extensive spectroscopic methods, particularly with one-dimensional (1D) and two-dimensional (2D) NMR, and, by comparison,...

Sumario:Two new 24-homoscalarane sesterterpenoids, felixins F (1) and G (2), were isolated from the sponge Ircinia felix. The structures of new homoscalaranes 1 and 2 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 and 2 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 (IC(50) ≤ 5.0 μM).
