The (S,S)-enantiomer of combretadioxolane (3), designed as a chirally preorganized derivative of combretastatin A-4, exhibited quite strong tubulin polymerization-inhibitory activity (IC50: 4-6 mu M) (S,S)-3 is 20 times more potent than vincristine as an in vitro growth inhibitor (in terms of GI(50)) of the multi-drug-resistant (MDR) cell line PC-12, which produces P-glycoprotein.
