Colchicine binding site inhibitors (CBSIs) hold great potential in developing new generations of antimitotic drugs. Unlike existing tubulin inhibitors such as paclitaxel, they are generally much less susceptible to resistance caused by the overexpression of drug efflux pumps. The 3,4,5-trimethoxyphenyl (TMP) moiety is a critical component present in many CBSIs, playing an important role in maintaining

materials for the synthetic scheme were easily available from plant extracts. The targeted molecules were further tested in the phenotypic seaurchinembryo assay to identify compounds with antimitotic microtubule destabilizing activity. Structure–activityrelationship studies suggested that the structural features essential for potent antiproliferative activity include: 1) 5-aminoisoxazole bridge linking
