Quinones 262-270 cytochrome P450 family 1 subfamily B member 1 Homo sapiens 76-82 14679015-1 2003 The Phase I enzyme cytochrome p450 1B1 (CYP1B1) has been postulated to play a key role in estrogen-induced mammary carcinogenesis by catalyzing the oxidative metabolism of 17beta-estradiol (E(2)) to catechol estrogens (2-OHE(2) and 4-OHE(2)) and highly reactive estrogen quinones (E(2)-2,3-Q and E(2)-3,4-Q). Quinones 271-279 cytochrome P450 family 1 subfamily B member 1 Homo sapiens 40-46 32986415-3 2020 In this study hop extract and its bioactive compounds were investigated for its mechanism of action within the chemical estrogen carcinogenesis pathway, which is mainly mediated through the 4-hydroxylation pathway catalyzed by CYP1B1 that can form gentoxic quinones. Quinones 257-265 cytochrome P450 family 1 subfamily B member 1 Homo sapiens 227-233 19250193-6 2009 Using rate constants of genetic variants of CYP1A1, CYP1B1, and COMT, the model further allowed examination of the kinetic impact of enzyme polymorphisms on the entire metabolic pathway, including the identification of those haplotypes producing the largest amounts of catechols and quinones. Quinones 283-291 cytochrome P450 family 1 subfamily B member 1 Homo sapiens 52-58 17570247-11 2007 These experiments demonstrated that CYP1A1, CYP1B1, and CYP3A4 are able to oxidize catechol estrogens to their respective quinones, which can further react with GSH, protein, and DNA, the last resulting in depurinating adducts that can lead to mutagenesis. Quinones 122-130 cytochrome P450 family 1 subfamily B member 1 Homo sapiens 44-50 17234793-5 2007 Because the reactive quinones were produced as part of the CYP1B1-mediated oxidation reaction, the adduct formation followed Michaelis-Menten kinetics. Quinones 21-29 cytochrome P450 family 1 subfamily B member 1 Homo sapiens 59-65 12810639-1 2003 Cytochrome P450 1A1 (CYP1A1) and 1B1 (CYP1B1) catalyze the oxidative metabolism of 17 beta-estradiol (E2) to catechol estrogens (2-OHE2 and 4-OHE2) and estrogen quinones, which may lead to DNA damage. Quinones 161-169 cytochrome P450 family 1 subfamily B member 1 Homo sapiens 38-44 19138946-4 2008 CYP1B1 favors quinone formation by catalyzing estrogen 4-hydroxylation, whereas NAD(P)H quinone oxidoreductase 1 (NQO1) catalyzes the protective reduction of quinones to catechols.
