The synthesis of twenty-six 4-arylcoumarin analogues of combretastatin A-4 (CA-4) led to the identification of two new compounds (25 and 26) with strong cytotoxic activity. Both compounds had a high cytotoxic effect on a CA-4-resistant colon adenocarcinoma cell line (HT29D4). The compounds affected cell cycle progression characterized by a mitotic block. The activity of these compounds against microtubules both in vitro and in cells was examined and both compounds were found to potently inhibit in vitro microtubule formation via a sub-stoichiometric mode like CA-4. By immunofluorescence, it was observed that both compounds induced strong microtubule network disruption. Our results provide a strong experimental basis to develop new potent anti-tubulin molecules targeting CA-4-resistant cancer cells.
