Abstract: NAD(P)H quinone oxidoreductase (NQO1) has multiple functions in the cell including an ability to act as a detoxifying enzyme and as a protein chaperone. The latter property is particularly important in oncology as one of the client proteins of NQO1 is p53. The inhibitor, dicoumarol, is classically used to probe the biological properties of NQO1, but interpretation of enzyme function is compromised by the multiple "off-target" effects of this agent. Coumarin-based compounds that are more potent than dicoumarol …
