Abstract :

Analogs of antimitotic natural products combretastatin A-4 (CA4), podophyllotoxin (PT) and flavanoids were synthesized using allylpolyalkoxybenzenes from Dill and Parsley seed essential oils. The targeted molecules were evaluated in vivo in a phenotypic sea urchin embryo assay for antimitotic and microtubule destabilizing activity. Structure activity relationship studies identified mostly active molecules with polymethoxyphenyl rings as potent antiproliferative agents. The effective threshold concentrations (EC) resulting in mitotic abnormalities in the sea urchin embryos were 0.25-1 nM. These molecules displayed high cytotoxicity against a panel of 60 human cancer cell lines including multi drug resistant cells. Cytotoxic effect of tested compounds was attributed to microtubule destabilization resulted in cell cycle arrest followed by apoptotic cell death. Considering encouraging data from phenotypic and mechanistic studies, some compounds may prove to be lead candidates for further in vivo studies to assess its potential as anti-tumor agents.
