All of our assays were prepared under red light (darkroom) and were incubated in the dark, as it is known that the thiarubrines are photoreactive: Block, E.; Page, J.; Toscano, J.

It has previously been reported (ref 6) that thiarubrines can produce Superoxide; however, to the best of our knowledge experimental conditions and data supporting this statement have not been published.

The observed metal dependence in our reactions (indicated by inhibition of DNA cleavage by the metal chelator desferal) may reflect the requirement for transition metal ions such as copper or iron in an initial thiol oxidiation reaction as well as in the subsequent Fenton reaction. See ref 13
