A new class of antineoplastic agents, the 5-substituted imidazo[4,5,1-de]acridin-6-ones with an (aminoalkyl)amino group in the side chain, has been made. These compounds were synthesized by reduction of 1-substituted 4-nitroacridin-9(10H)-ones and subsequent reaction of the derived amines with carboxylic acids. Their cytotoxic activity against HeLaS3 cells in tissue culture and in vivo antitumor activity

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 tertiary aminoalkyl side chain of the
