Abstract

Imidazoacridin-6-ones are shown to be potent nanomolar inhibitors of the enzyme NQO2. By use of computational molecular modeling, a reliable QSAR was established, relating inhibitory potency with calculated binding affinity. Further, crystal structures of NQO2 containing two of the imidazoacridin-6-ones have been solved. To generate compounds with reduced off-target (DNA binding) effects, an N-oxide moiety was introduced into the ...
