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