Structures of cytotoxic products from Fe-catalyzed oxidation of sesamol in ethanol

The iron-ion catalyzed oxidation of ethanol solution of sesamol, a potent antioxidant of sesame, afforded two significant cytotoxic products to normal mammalian cells. The structures were determined using extensive NMR spectroscopy as a new sesamol trimer and tetramer.

Two cytotoxic oxidation products of sesamol, a potent antioxidant in sesame, was isolated. Their structures were determined to be a new sesamol trimer and tetramer.
