Dicumarol 191-200 NAD(P)H quinone dehydrogenase 1 Homo sapiens 73-86 7531691-10 1995 The results suggest that DT-diaphorase shows the same properties as the C-C transhydrogenases, and the binding of dicumarol elicits a conformational change or an adjustment in the polarity of the FAD pocket.

This induction was shown to be dose dependent and immunoprecipitation experiments with DIA-1 anti-serum demonstrated an increase in the DIA-1 protein level in dicoumarol-treated larvae. Dicumarol 320-330 Dvir\Dia1 Drosophila virilis 32-37 7537551-3 1995 The induction of DIA1 by dicoumarol was found to be blocked by actinomycin D, which suggests a transcriptional mechanism of regulation. Dicumarol 25-35 Dvir\Dia1 Drosophila virilis 17-21 7537551-4 1995 The opposite effect of dicoumarol on DIA-1 in vitro vs. in vivo suggests that a metabolic conversion takes place after the ingestion of this compound by D. virilis larvae. Dicumarol 23-33 Dvir\Dia1 Drosophila virilis 37-42 21559647-6 1994 The IC50 value of PC-9 against MMC significantly decreased by co-incubation with dicumarol under aerobic, but not under hypoxic conditions.

Dicumarol 12-21 proprotein convertase subtilisin/kexin type 9 Homo sapiens 80-84 7927920-9 1994 DTD activity in the PC-9 cell line was inhibited by treatment with dicumarol while in PC-9/MC4 it remained unchanged. Dicumarol 67-76 proprotein convertase subtilisin/kexin type 9 Homo sapiens 20-24 7526885-11 1994 Moreover, this correlation was lost when cells were exposed to drug in the presence of dicoumarol, supporting an involvement of DT-diaphorase in this relationship. Dicumarol 87-97 NAD(P)H quinone dehydrogenase 1 Homo sapiens 128-141 8077054-5 1994 Further support is indicated by: 1) reduction in the differential in toxicity between the 2 cell lines by BMY 25282; and 2) a higher effect of DT-diaphorase inhibitor dicumarol on the wild-type cells compared with J82/MMC.

Dicumarol 5-14 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 32-45 7527260-10 1994 Although mouse quinone reductase has an amino acid sequence similar to those of the rat and human enzymes, the mouse enzyme has a higher NAD(P)H-menadione reductase activity and is less sensitive to flavones and dicoumarol, 2 known inhibitors of the enzyme.

Dicumarol 31-41 NAD(P)H quinone dehydrogenase 1 Homo sapiens 59-72 8216372-4 1993 Whereas NAD(P)H:quinone reductase (NAD(P)H:(quinone acceptor) oxidoreductase; DT diaphorase; EC 1.6.99.2) was the predominant 4NQO reductase present in liver cytosol from Sprague-Dawley rats, dicumarol-resistant NADH:4NQO nitroreductase specific activities were comparable with those of mouse liver cytosols.

Dicumarol 250-260 NAD(P)H quinone dehydrogenase 1 Homo sapiens 0-13 7946565-3 1994 The role of DT-diaphorase in determining drug sensitivity was confirmed by using the enzyme inhibitor dicoumarol, which protects cells containing high levels of DT-diaphorase from the cytotoxic action of EO9. Dicumarol 102-112 NAD(P)H quinone dehydrogenase 1 Homo sapiens 12-25 7946565-3 1994 The role of DT-diaphorase in determining drug sensitivity was confirmed by using the enzyme inhibitor dicoumarol, which protects cells containing high levels of DT-diaphorase from the cytotoxic action of EO9. Dicumarol 102-112 NAD(P)H quinone dehydrogenase 1 Homo sapiens 161-174 8268208-6 1993 This observed activity was sensitive to dicumarol, a potent inhibitor of quinone reductase activity. Dicumarol 40-49 crystallin, zeta Mus musculus 73-90 7685584-6 1993 When DT-diaphorase activity was inhibited by non-toxic dicoumarol (50 microM), DNA damage and cytotoxic activity induced by MMC were decreased in all cells examined.

Dicumarol 37-46 xanthine dehydrogenase Homo sapiens 50-72 1281039-1 1992 These studies examined the effect of dicumarol on xanthine dehydrogenase (XDH), an enzyme recently shown to bioreduce mitomycin C. Dicumarol 37-46 xanthine dehydrogenase Homo sapiens 74-77 1281039-2 1992 Dicumarol, which has previously been shown to inhibit xanthine oxidase (XO), inhibited both XDH and XO mediated conversion of xanthine to uric acid but potentiated the metabolism of mitomycin C by XDH and XO.

Dicumarol 147-156 xanthine dehydrogenase Homo sapiens 72-75 1382426-1 1992 Dicumarol, often used as a specific inhibitor of DT diaphorase (NAD(P)H:(quinone-acceptor) oxidoreductase; EC 1.6.99.2), was found to potently inhibit GSH transferases (EC 2.5.1.18). Dicumarol 0-9 NAD(P)H dehydrogenase, quinone 1 Mus musculus 49-62 1382426-7 1992 Whereas several other non-substrate ligands were more potent inhibitors of 1-chloro-2,4-dinitrobenzene conjugation, dicumarol effectively inhibited GSH transferase and GSH peroxidase II activities in the range of dicumarol concentrations frequently used for detection of DT diaphorase action. Dicumarol 116-125 NAD(P)H dehydrogenase, quinone 1 Mus musculus 271-284 1382426-8 1992 These results indicate that physiological consequences resulting from the use of supramicromolar concentrations of dicumarol should not be interpreted in terms of DT diaphorase inhibition alone. Dicumarol 115-124 NAD(P)H dehydrogenase, quinone 1 Mus musculus 163-176 1544832-5 1992 Enzyme activity was measured spectrophotometrically by dicoumarol inhibitable cytochrome c reduction in the presence of drug, and aerobic cytotoxicity was assessed by the MTT assay. Dicumarol 55-65 cytochrome c, somatic Homo sapiens 78-90 1379126-2 1992 The cytosol-dependent decrease in chromium(VI) mutagenicity was found to be counteracted in the presence of dicumarol, an inhibitor of the cytosolic enzyme NAD(P)H:quinone oxidoreductase (DT-diaphorase). Dicumarol 108-117 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 188-201 1379126-7 1992 Inhibition of 90% of the cytosolic DT-diaphorase activity by dicumarol led to only partial (20-22%) inhibition of chromium(V) formation. Dicumarol 61-70 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 35-48 1375532-6 1992 Inhibition of hepatocyte DT-diaphorase by dicumarol increased trenimon-induced cytotoxicity by approximately 10-fold, and markedly inhibited hydroquinone formation.

Dicumarol 44-53 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 27-40 1370822-7 1992 Dicumarol, an inhibitor of quinone acceptor oxidoreductase, decreased the production of the hydroxyl radical and attenuated DNA strand breaks in MCF-7 cells treated with MD. Dicumarol 0-9 thioredoxin reductase 1 Homo sapiens 44-58 1371615-11 1992 Additionally, dicoumarol, an inhibitor of QR activity, potentiated HQ-induced toxicity in both strains of bone marrow stromal cells. Dicumarol 14-24 crystallin, zeta Mus musculus 42-44 1371987-3 1992 Inhibition of DT-diaphorase by dicoumarol markedly inhibited the cytotoxic activity of trenimon to the resistant L5178Y/HBM10 cells. Dicumarol 31-41 NAD(P)H dehydrogenase, quinone 1 Mus musculus 14-27 1373799-4 1992 In L5178Y/HBM10 cells, dicoumarol, an inhibitor of DT-diaphorase, decreased cell kill and DNA cross-linking by mitomycin C in air but had no significant effect on these activities under hypoxia.

Dicumarol 248-258 fatty acid binding protein 1 Rattus norvegicus 185-191 1893498-4 1991 Concerning the reduction mechanism by PB-3c cells we can see that superoxide dismutase (SOD) has no influence on the rate of reduction, but dicumarol almost completely inhibits the reduction at a concentration greater than 1 x 10(-6) M. Therefore, it can be concluded that CV-6504 is reduced mainly by two electron donating enzymes without the intermediary of a semiquinone radical and that the resulting hydroquinone inhibits lipid peroxidation as well as 5-lipoxygenase activity. Dicumarol 140-149 arachidonate 5-lipoxygenase Mus musculus 457-471 1874176-1 1991 A water-soluble quinone, coenzyme Q0 (CoQ0), was shown to stimulate insulin release, and dicumarol, an inhibitor of quinone reductase, inhibited glucose-induced insulin release in pancreatic islets. Dicumarol 89-98 insulin Homo sapiens 161-168 1874176-4 1991 The relative rates of activity with various substrates (CoQ0 approximately equal to durohydroquinone greater than menadione greater than duroquinone greater than CoQ6 = CoQ10 greater than ferricyanide) were similar to those described previously for quinone reductase from liver Dicumarol, chlorpromazine, and T3 were much more potent inhibitors of the enzyme when NADPH was the coenzyme than when NADH was the coenzyme. Dicumarol 278-287 coenzyme Q6, monooxygenase Homo sapiens 162-166 1720333-7 1991 Dicumarol, an inhibitor of quinone reductase, did not inhibit CoQ0-induced insulin release, but it did inhibit glucose-induced insulin release suggesting that the enzyme and quinones play a role in glucose-induced insulin release. Dicumarol 0-9 insulin Homo sapiens 127-134 1720333-7 1991 Dicumarol, an inhibitor of quinone reductase, did not inhibit CoQ0-induced insulin release, but it did inhibit glucose-induced insulin release suggesting that the enzyme and quinones play a role in glucose-induced insulin release.

Dicumarol 44-54 NAD(P)H quinone dehydrogenase 1 Homo sapiens 27-40 1718826-8 1991 Thus, the concentration of dicoumarol used to inhibit DT-diaphorase must be chosen carefully and consideration should be given to the efficiency of the electron acceptor. Dicumarol 27-37 NAD(P)H quinone dehydrogenase 1 Homo sapiens 54-67 1718826-10 1991 Although higher doses of dicoumarol may be required to inhibit DT-diaphorase mediated metabolism of less efficient electron acceptors, the use of such doses in cells may also affect biochemical processes other than DT-diaphorase and should be approached with caution. Dicumarol 25-35 NAD(P)H quinone dehydrogenase 1 Homo sapiens 63-76 1701687-2 1990 The addition of dicoumarol (10(-4) M-3 x 10(-4) M), a specific inhibitor of DT diaphorase, resulted in an intensification of the cytotoxicity of menadione, supporting the hypothesis that DT diaphorase protects cells against the oxidative stress induced by quinones. Dicumarol 16-26 NAD(P)H quinone dehydrogenase 1 Homo sapiens 76-89 1701687-2 1990 The addition of dicoumarol (10(-4) M-3 x 10(-4) M), a specific inhibitor of DT diaphorase, resulted in an intensification of the cytotoxicity of menadione, supporting the hypothesis that DT diaphorase protects cells against the oxidative stress induced by quinones. Dicumarol 16-26 NAD(P)H quinone dehydrogenase 1 Homo sapiens 187-200 1701687-3 1990 On the other hand, the toxicity of 4NQO was greatly reduced by the addition of dicoumarol (10(-5) M-3 x 10(-4) M), showing that DT diaphorase is the key (or the sole) enzyme involved in the activation of 4NQO in the above cells. Dicumarol 79-89 NAD(P)H quinone dehydrogenase 1 Homo sapiens 128-141 1703398-6 1990 The expressed DT-diaphorase exhibited high activity of menadione reduction and was inhibited by dicumarol at a concentration of 10(-5)M. After purification by Cibacron Blue affinity chromatography, the expressed enzyme migrated as a single band on 12.5% sodium dodecyl sulfate-polyacrylamide gel with a molecular weight equivalent to that of the purified rat liver cytosolic DT-diaphorase.

Dicumarol 26-35 NAD(P)H quinone dehydrogenase 1 Homo sapiens 206-219 1692249-9 1990 Dicoumarol, an inhibitor of DT-diaphorase, increased the cytotoxic activity of both benzoquinone mustard and benzoquinone dimustard in L5178Y/HBM10 cells. Dicumarol 0-10 NAD(P)H dehydrogenase, quinone 1 Mus musculus 28-41 2116241-4 1990 Experiments on the identification of reduction products and on the inhibition with dicoumarol and the antiserum indicated that DT-diaphorase catalyzes 4-electron reduction of C-nitroso-compounds and plays a major role in the reduction of these compounds by rat liver cytosol. Dicumarol 83-93 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 127-140 2125671-3 1990 Dicumarol exerts characteristic inhibition on DT-diaphorase, whereas serum albumin and certain non-ionic detergents exert activation. Dicumarol 0-9 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 46-59 1701346-11 1990 Metabolism of mitomycin C by purified HT-29 DT-diaphorase was also dicoumarol inhibitable and pH dependent.

Dicumarol 116-126 coagulation factor II, thrombin Homo sapiens 48-59 1699555-1 1990 The role of gamma-carboxyglutamic acid (Gla) in prothrombin function can be effectively evaluated by characterizing dicoumarol-induced, Gla-deficient prothrombin structural isomers. Dicumarol 116-126 coagulation factor II, thrombin Homo sapiens 150-161 2113030-4 1990 Prior boiling of cytosol, omission of NADH or NADPH or inclusion of dicoumarol, an inhibitor of DT-diaphorase, inhibited removal of AZQ.

Dicumarol 139-149 NAD(P)H quinone dehydrogenase 1 Homo sapiens 107-120 2553092-5 1989 Menadione, at concentrations up to 25 microM, did not inhibit either protein or RNA synthesis unless dicoumarol, an inhibitor of DT-diaphorase, was also present. Dicumarol 101-111 NAD(P)H quinone dehydrogenase 1 Homo sapiens 129-142 2105732-3 1990 Both reductions had the classic characteristics of DT-diaphorase: they were equally supported by NADPH and NADH and almost entirely inhibited by dicumarol. Dicumarol 145-154 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 51-64 34252539-5 2021 Similar to dicoumarol, the specific inhibitor of NQO1, both Nec-1 and Nec-1s significantly suppress NQO1-dependent cell death. Dicumarol 11-21 NAD(P)H quinone dehydrogenase 1 Homo sapiens 49-53 2500115-1 1989 The dicoumarol-sensitive NAD(P)H:quinone reductase (E.C.1.6.99.2), often referred to as DT-diaphorase, has been purified from both the cytosolic and microsomal fractions from rat liver using a novel, highly efficient, two-step purification procedure utilizing immobilized Cibacron Blue F3GA dye affinity chromatography as the principal step.

Dicumarol 213-222 chymase 1 Canis lupus familiaris 16-23 2472556-7 1989 By contrast, the pretreatment with the NAD(P)H-quinone reductase (DT-diaphorase) inhibitor, dicumarol, markedly increased the rate of appearance of the toxic effect of menadione. Dicumarol 92-101 NAD(P)H dehydrogenase [quinone] 1 Cavia porcellus 66-79 3115561-1 1987 Dicumarol sensitive DT-diaphorase (EC 1.6.99.2) activity has been measured in human cytosol from liver and various extrahepatic tissues not containing tumors which were removed during elective operations. Dicumarol 0-9 NAD(P)H quinone dehydrogenase 1 Homo sapiens 20-33 2455523-5 1988 When control and induced cells were also exposed to dicoumarol, a specific and potent inhibitor of DT-diaphorase, the cytotoxicity of the quinones in both control and induced cells was enhanced markedly. Dicumarol 52-62 NAD(P)H dehydrogenase, quinone 1 Mus musculus 99-112 2451576-1 1988 The metabolic activation or detoxification of mutagens and carcinogens of several chemical classes was investigated in the presence of various rat liver and lung subcellular fractions and of dicoumarol, a specific inhibitor of DT diaphorase activity. Dicumarol 191-201 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 227-240 2451512-11 1988 Ubiquinone-6, ubiquinone-10 and dicoumarol stimulate protoporphyrinogen oxidase activity at low concentrations (less than 15 microM), whereas coenzyme Q0 and menadione show no activation at these concentrations. Dicumarol 32-42 protoporphyrinogen oxidase Mus musculus 53-79 3338873-7 1988 An anti-coagulant, dicoumarol, abrogated the effect of rTNF-alpha. Dicumarol 19-29 tumor necrosis factor Rattus norvegicus 55-65 2465220-5 1988 However, we were unable to confirm the comparatively marked increase AT III for dicoumarol treatment found by Roka and Bleyl. Dicumarol 80-90 serpin family C member 1 Homo sapiens 69-75 2465958-3 1988 In a group of 347 patients under dicoumarol therapy of different intensity and duration PIVKA was detected in BaSO4 adsorbed PPP only in samples where prothrombin level (Quick"s test) was lower than 50% of normal values. Dicumarol 33-43 coagulation factor II, thrombin Homo sapiens 151-162 3304203-10 1987 Inhibition of phase II led to a significant increase in the steady state level of singlet oxygen, as did the inhibition of two-electron reduction by using the inhibitor dicoumarol for DT diaphorase. Dicumarol 169-179 NAD(P)H quinone dehydrogenase 1 Homo sapiens 184-197 2434474-5 1987 Thus, in previous studies, we showed that treatment of mice with BHA (2(3)-tert-butyl-4-hydroxyanisole), which elevates cytosolic quinone reductase activity about 10-fold, reduced menadione-dependent chemiluminescence of hepatic post-mitochondrial supernatant fractions, whereas inhibition of quinone reductase by dicoumarol greatly intensified light emission. Dicumarol 314-324 crystallin, zeta Mus musculus 130-147 2435285-4 1987 Since both NADP and dicoumarol inhibited the naphthazarin-stimulated non-stoichiometric consumption of NADPH and oxygen then naphthazarin redox cycling probably involves both DT-diaphorase and NADPH cytochrome P-450 reductase. Dicumarol 20-30 cytochrome p450 oxidoreductase Homo sapiens 193-225 6204727-4 1984 Quantitative cytochemistry of unfixed, undemineralized sections showed that dicumarol also markedly affected the periosteal activities of glucose 6-phosphate dehydrogenase and of alkaline phosphatase in the first 2 mm from the fracture measured at 3 and 5 days postfracture when normally, new bone is first formed. Dicumarol 76-85 glucose-6-phosphate dehydrogenase Rattus norvegicus 138-171 2431654-1 1986 The effect of dicoumarol on glucuronidation of 3-OH-benzo(a)pyrene (BP) appears to be due to inhibition of UDPglucuronosyltransferase (UDPGT) and not to an inhibited DT-diaphorase (NAD(P)H:quinone oxidoreductase); to date the only enzyme known to be inhibited by dicoumarol. Dicumarol 14-24 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 166-179 2425252-4 1986 The presence of dicumarol, a specific inhibitor of the two-electron reduction of quinones by DT-diaphorase, afforded some protection against cytotoxicity. Dicumarol 16-25 NAD(P)H quinone dehydrogenase 1 Homo sapiens 93-106 4060194-3 1985 In fibroblasts, effects on both DNA and membrane integrity were potentiated by the presence of dicoumarol, a specific inhibitor of the 2-electron reduction of quinones by DT-diaphorase, whereas in hepatocytes only the cell membrane damage was sensitive to dicoumarol. Dicumarol 95-105 NAD(P)H quinone dehydrogenase 1 Homo sapiens 171-184 6437671-7 1984 Exposure of cell sonicates to dicumarol inhibited DT-diaphorase activity, while the rate of formation of reactive metabolites of MC was enhanced. Dicumarol 30-39 NAD(P)H dehydrogenase, quinone 1 Mus musculus 50-63 6203538-3 1984 Dicoumarol, an inhibitor of DT diaphorase, did not potentiate menadione-induced DNA strand breaks. Dicumarol 0-10 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 28-41 30260338-1 1987 THE EFFECTS OF DICUMAROL, A SPECIFIC INHIBITOR OF DT-DIAPHORASE, WERE INVESTIGATED IN THE AMES REVERSION TEST BY ASSAYING SEVERAL MUTAGENS OF DIFFERENT CHEMICAL CLASSES IN THE PRESENCE OF A VARIETY OF METABOLIC SYSTEMS. Dicumarol 15-24 NAD(P)H quinone dehydrogenase 1 Homo sapiens 50-63 3934922-10 1985 The DT-diaphorase inhibitor dicoumarol was employed to show that this enzyme is not involved in the activation of mitomycin C to a cytotoxic agent. Dicumarol 28-38 NAD(P)H dehydrogenase, quinone 1 Mus musculus 4-17 2419579-6 1985 Moreover, we have found that the cytotoxic effects of DBNQ on human tumor and murine bone marrow stem cells can be prevented or lessened by pretreatment of the cells with dicoumarol, a potent inhibitor of DT-diaphorase. Dicumarol 171-181 NAD(P)H dehydrogenase, quinone 1 Mus musculus 205-218 6200119-5 1984 The toxicity of 1-naphthol and the naphthoquinones was potentiated by dicoumarol, an inhibitor of DT-diaphorase (NAD(P)H:quinone oxidoreductase). Dicumarol 70-80 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 98-111 6749127-9 1984 This effect was reversed in the presence of dicumarol, a specific inhibitor of DT-diaphorase. Dicumarol 44-53 NAD(P)H dehydrogenase [quinone] 1 Cavia porcellus 79-92 6200119-5 1984 The toxicity of 1-naphthol and the naphthoquinones was potentiated by dicoumarol, an inhibitor of DT-diaphorase (NAD(P)H:quinone oxidoreductase). Dicumarol 70-80 crystallin zeta Rattus norvegicus 121-143 6188454-3 1983 Daunorubicin toxicity increased in the presence of dicoumarol, a specific inhibitor of DT-diaphorase. Dicumarol 51-61 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 87-100 6165325-0 1981 Biospecific adsorption of hepatic DT-diaphorase on immobilized dicoumarol. Dicumarol 63-73 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 34-47 6191666-2 1983 Chemiluminescence was augmented when the two-electron reduction of the quinone catalyzed by NAD(P)H:quinone reductase was inhibited by dicoumarol, thus underlining the protective function of this enzyme also known as DT-diaphorase. Dicumarol 135-145 NAD(P)H quinone dehydrogenase 1 Rattus norvegicus 217-230 6802189-4 1982 The inhibitor of mitochondrial NADH-cytochrome b5 reductase dicumarol prevented the cytochrome P-450 reduction in the presence of glutamate, NAD+ and amytal but did not affect the reduction of cytochrome P-450 by the added NADH.
