Quinone Reductase
Quinone Reductase
Quinones, a class of organic compounds, are formally derived from aromatic compounds and are a subset of the quinoid family which also contains the quinone imines and the quinone methides. NQO1 (QR1, EC 1.6.99.2), also referred to as DT-diaphorase (formerly), nicotinamide quinone oxidoreductase 1, quinone reductase type 1, or menadione reductase, is a cytosolic flavoenzyme. Another member of the quinone oxidoreductases family is NQO2 (QR2, EC 1.10.99.2) which is also a FAD bound protein (25 kDa) and closely related to NQO1. In addition to NQO1 and NQO2 found in humans, an ancient NQO3 subfamily exists in eubacteria, NQO4 subfamily in fungi, and NQO5 subfamily in archaebacteria[1][2].

KL1333
0 ImagesKL1333, a derivative of β-lapachone, is an orally available NAD+ modulator. KL1333 reacts with NAD(P)H:quinone oxidoreductase 1 (NQO1) as a substrate, resulting in increases in intracellular NAD+ levels via NADH oxidation. KL1333 improves energy metabolism and mitochondrial dysfunction in MELAS fibroblasts. KL1333 protects against Cisplatin-induced ototoxicity in mouse cochlear cultures. -

NIR-ASM
0 ImagesCat. No.: HY-D3209CAS No.: 2646628-35-3NIR-ASM is a near-infrared fluorescent probe that can cross cell membranes and be activated by NQO1. NIR-ASM can distinguish NQO1-expressing cancer cells from normal cells via fluorescence microscopy and flow cytometry. NIR-ASM generates near-infrared fluorescence with a high signal-to-noise ratio in tumor models with NQO1 activity, enabling the detection of endogenous NQO1 activity in vivo. NIR-ASM is applicable to the research of lung cancer and breast cancer. -

Casimiroin
0 ImagesCasimiroin is a QR2 and Aromatase inhibitor, with an IC50 of 54.1 μM against QR2 and an IC50 of 3.92 μM against aromatase. Casimiroin exhibits antimutagenic activity and inhibits DMBA (HY-W011845)-induced mutations in Salmonella typhimurium. Casimiroin suppresses DMBA-induced precancerous lesions in mouse mammary organ cultures. Casimiroin can be used in breast cancer-related research. -

4-Hydroxyphenyl acetate
0 Images4-Hydroxyphenyl acetate (4-HPA) is a natural antioxidant and protects cells from oxidative stress-induced necrosis. 4-Hydroxyphenyl acetate blocks the increase of cellular ROS induced by oxidative stress, and up-regulates NQO1 and HO-1 genes by stabilizing and inducing the nuclear translocation of NRF2 transcription factor. -

Tretazicar
0 ImagesSynonyms: CB 1954Tretazicar (CB 1954), an antitumor proagent, is highly selective against the Walker 256 rat tumour line. Tretazicar is enzymatically activated to generate a bifunctional agent, which can form DNA-DNA interstrand cross-links. Tretazicar in rat cells involves the reduction of its 4-nitro group to a 4-hydroxylamine by the enzyme NAD(P)H:quinone oxidoreductase 1 (NQO1). -
