ACTIVATION BY NQO1
The enzyme NQO1 is typically a detoxification enzyme, catalyzing the reduction and elimination of exogenous and endogenous quinones. However, in 2012 we discovered that the action of NQO1 on the compound deoxynyboquinone (DNQ) results in reduction to the hydroquinone, followed by rapid conversion back to DNQ, and generating toxic reactive oxygen species in the process. As NQO1 is not appreciable expressed in normal tissue and is highly expressed in many solid tumors, DNQ rapidly and selectively generates ROS in tumor cells, and is very potent both in cell culture and in mouse models of cancer. DNQ and its derivatives have tremendous potential as potent and personalized anticancer agents.
