“ Mn(II)- or Cu(II)-catalyzed autoxidation of caffeic acid produced H2O2 with efficiency of Mn(II) greater than Cu(II).”
“Pulsed field gel electrophoresis showed that caffeic acid induced DNA strand breaks in cultured human cells in the presence of Mn(II).”
“The Cu(II)-mediated DNA damage was enhanced by pre-incubation of caffeic acid with Mn(II).”
