NAD(P)H:quinone oxidoreductase 1 (NQO1) in the sensitivity and resistance to antitumor quinones

Abstract

The quinone pharmacophore is present in many drug classes but is particularly common among antitumor drugs. Many quinones serve essentially as pro-drugs and exert their activities after reduction. Reduction of quinones may generate semiquinones or hydroquinones with subsequent generation of reactive oxygen radicals and oxidative stress, quinones can be designed so they lose a leaving group when reduced to the hydroquinone generating a reactive electrophile or the hydroquinone form of the molecule may have greater pharmacological activity than the parent quinone against a particular target. Enzyme systems that reduce quinones therefore become critically important in the pharmacological activity of this class of drugs. There are a number of enzyme systems that can catalyze reduction of quinones including cytochrome P450 reductase, cytochrome b5 reductase, NAD(P)H:quinone oxidoreductase 1 (NQO1), NAD(P)H:quinone oxidoreductase 2 (NQO2), carbonyl reductases, and thioredoxin reductase. In this context, one of the most extensively studied reductases has been NAD(P)H:quinone oxidoreductase 1 (NQO1). In this review we will focus on the role of NQO1 in the bioactivation of clinically important quinones mitomycin C, β-lapachone and 17AAG as well as the influence of the NQO1*2 polymorphism on the sensitivity and resistance to these agents.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
