  Naphtho[1',2':4,5]imidazo[1,2-a]pyridine-5,6-diones (NPDOs), a new type of N-heterocycle-fused o-quinones, have been synthesized. They have been found to be efficient electron-accepting substrates of NADPH-dependent single-electron-transferring P-450R and two-electron transferring NQO1, generating reactive oxygen species (ROS) with a concomitant decrease in NADPH, which is consistent with redox-cycling. The reactivity of NPDOs toward P-450R (in terms of k(cat)/K-m) varied in the range of 10(6)-10(7) M-1 s(-1), while their reduction by NQO1 proceeded much faster, approaching the diffusion control limit (k(cat)/K-m similar to 10(8)-10(9) M-1 s(-1)). NPDOs exhibited relatively high cytotoxic activity against human lung carcinoma (A-549) and breast tumor (MCF-7) cell lines (LC50 = 0.1-8.3 mu M), while promyelocytic leukemia cells (HL-60) were less sensitive to NPDOs (LC50 >= 10 mu M). 3-Nitro-substituted NPDO (11) revealed the highest potency against both A-549 and MCF-7 cell lines, with LC50 of 0.12 +/- 0.03 mu M and 0.28 +/- 0.08 mu M, respectively. Dicoumarol partly suppressed the activity of the compounds against A-594 and MCF-7 cell lines, suggesting that their cytotoxic action might be partially influenced by NQO1-mediated bioreductive activation.
