Provided are compounds according to the following Formula I:
The Formula I compounds are activated in the presence of reactive oxygen species (ROS) and are therefore selective anti-cancer therapeutics for cancers associated with elevated ROS. Also provided are methods and pharmaceutical compositions for treating cancers associated with increased ROS.

This study explores the possible use of reactive oxygen-activated DNA modifying agents against acute myeloid leukemia (AML). A key amine on the lead agent was investigated via cytotoxicity assays and was found necessary for potency. The two best compounds were screened via the NCI-60 cell panel. These two compounds had potency between 200 and 800 nM against many of the leukemia cancer cell types. Subsequent experiments explored activity against a transformed AML model that mimics the molecular signatures identified in primary AML patient samples. A lead compound had an IC50 of 760 nM against this AML cell line as well as a therapeutic index of 7.7 +/- 3 between the transformed AML model cell line and non-cancerous human CD34+ blood stem/progenitor cells (UCB). The selectivity was much greater than the mainstays of AML treatment: doxorubicin and cytarabine. This manuscript demonstrates that this novel type of agent may be useful against AML.
