Abstract

The absolute configuration of dilospirane B (1), a diterpene featuring a novel carbon framework recently isolated from the brown alga Dilophus spiralis, was established on the basis of theoretical calculations of its electronic circular dichroism spectra applying the time-dependent density functional theory method. Metabolite 1, evaluated for its in vitro antitumor activity against six human cancer cell lines displaying various levels of sensitivity to pro-apoptotic stimuli, exhibited growth inhibitory activity with a mean IC ₅₀ value of 66 μM. Quantitative videomicroscopy analyses indicated that 1 initially displays cytostatic effects which later become cytotoxic.
