애플리케이션
Human DT diaphorase has been used in a study to assess the development of novel quinone phosphorodiamidate prodrugs. Human DT diaphorase has also been used to investigate its crystal structure for the development of a model for its interaction with the cytotoxic prodrug 5-(aziridin-1-yl)-2,4-dinitrobenzamide (CB1954).
생화학적/생리학적 작용
DT-diaphorase, also referred to as NAD(P)H:(quinone-acceptor) oxidoreductase, is involved in the reductive activation process of several cytotoxic antitumor quinones and nitrobenzenes. It catalyzes the two-electron reduction of quinones and quinonoid compounds to hydroquinones, using either NADH or NADPH as the electron donor. The flavoenzyme contains one mole of FAD per mole of enzyme.
NQO1 is a cytosolic homodimeric FAD-dependent enzyme that catalyses the reduction of a broad range of cytotoxic quinones resulting in protection from cellular oxidative stress. Oxidative stress may also enhance NQO1-mediated protection of p53 and p73 against proteasomal degredation. The highly Inducible expression of NQO1 is controlled by the Nrf2-Keap1/ARE pathway and appears to be affected by changes in susceptibility to oxidative stress. During Oxygen/glucose deprivation, NQO1 appears to be involved in AMPK-induced cancer cell death. NQO1 has been observed to be overexpressed in several types of solid tumors, including breast, pancreas, lung and colon cancer.
Shown to activate quinone based anti-tumor agents in vivo. Suitable for conjugation to carrier molecules.

DT-diaphorase (EC 1.6.99.2), also referred to as NAD(P)H:(quinone-acceptor) oxidoreductase, is involved in the reductive activation process of several cytotoxic antitumor quinones and nitrobenzenes. It has been observed in our and other laboratories that the rat enzyme is significantly more effective

A series of naphthoquinone and benzimidazolequinone phosphorodiamidates has been synthesized and studied as potential cytotoxic prodrugs activated by DT-diaphorase. Reduction of the quinone moiety in the target compounds was expected to provide a pathway for expulsion of the phosphoramide mustard

NAD (P) H: quinone oxidoreductase 1 (NQO1) is a xenobiotic metabolizing enzyme that detoxifies chemical stressors and antioxidants, providing cytoprotection in normal tissues. However, high-level expression of NQO1 has been correlated with numerous human malignancies, suggesting a role in carcinogenesis

NQO1 (NAD(P)H: quinone oxidoreductase-1), located on chromosome 16q22, functions primarily to protect normal cells from oxidant stress and electrophilic attack. Recent studies have revealed that NQO1 is expressed at a high level in most human solid tumors including those of
