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].

KI696 (Standard)
0 ImagesCat. No.: HY-101140RCAS No.: 1799974-70-1KI696 (Standard) is the analytical standard of KI696 (HY-101140). This product is intended for research and analytical applications. KI696 is a selective KEAP1/NRF2 protein-protein interaction inhibitor with a human Kd value of 1.3 nM. KI696 acts by competitively occupying the NRF2-binding pocket of the KEAP1 Kelch domain. KI696 blocks KEAP1-mediated ubiquitination and degradation of NRF2, promotes the translocation of NRF2 to the nucleus, activates the expression of downstream antioxidant genes, increases intracellular glutathione levels, and alleviates oxidative stress-induced cell damage and inflammatory cell infiltration in the lungs. KI696 reduces ozone-induced pulmonary oxidative damage and inflammatory cell accumulation in rats, and upregulates pulmonary antioxidant genes. KI696 can be used in research related to chronic obstructive pulmonary disease, oxidative stress and inflammation.
