1 Metabolism of diaziquone by NAD(P)H:(quinone acceptor) oxidoreductase (DT-diaphorase): role in diaziquone-induced DNA damage and cytotoxicity in human colon carcinoma cells. diaziquone NAD(P)H quinone dehydrogenase 1 Homo sapiens
2 Metabolism of diaziquone by NAD(P)H:(quinone acceptor) oxidoreductase (DT-diaphorase): role in diaziquone-induced DNA damage and cytotoxicity in human colon carcinoma cells. diaziquone NAD(P)H quinone dehydrogenase 1 Homo sapiens
3 AZQ (0-20 microM) induced dicumarol-inhibitable DNA interstrand cross-linking and cytotoxicity in HT-29 human colon carcinoma cells which have high DT-diaphorase activity but not in BE cells which have low DT-diaphorase activity. diaziquone NAD(P)H quinone dehydrogenase 1 Homo sapiens
4 AZQ (0-20 microM) induced dicumarol-inhibitable DNA interstrand cross-linking and cytotoxicity in HT-29 human colon carcinoma cells which have high DT-diaphorase activity but not in BE cells which have low DT-diaphorase activity. diaziquone NAD(P)H quinone dehydrogenase 1 Homo sapiens
5 DT-diaphorase was purified from HT-29 cells and metabolism of AZQ by this enzyme was confirmed. diaziquone NAD(P)H quinone dehydrogenase 1 Homo sapiens
6 These data show that AZQ can be metabolized by purified rat hepatic and human HT-29 DT-diaphorase and suggest that in HT-29 cells, DT-diaphorase catalyzed reduction of AZQ represents a bioactivation process leading to the production of genotoxic and cytotoxic metabolites. diaziquone NAD(P)H quinone dehydrogenase 1 Homo sapiens
