WebOct 28, 2003 · Abstract. Doxorubicin is a useful antineoplastic drug with multiple mechanisms of cytotoxicity. One such mechanism involves the reductive bioactivation of the quinone ring to a semiquinone radical, which can exert direct toxic effects and/or undergo redox cycling. We hypothesized that human NADPH-cytochrome P450 reductase … WebOct 18, 2024 · Cytochrome P450 (CYP450) enzyme-based drug metabolism is a key factor in DDI . ... R440 is very likely to be the main site of CYP2D6 binding to reductase . This research suggests that R440 plays an important role in the electron transfer and binding between CYP3A24 and its reductase. When it is destroyed, the metabolism of FF and …
WebFeb 4, 2024 · POR is an oxidoreductase located in the endoplasmic reticulum that uses FAD and FMN as its cofactors to donate electrons from NADPH to cytochrome P450 (CYPs) as well as other proteins, and it participates in controlling xenobiotic detoxification and redox homeostasis (Pandey and Fluck, 2013 ).

WebApr 28, 2024 · CYP enzymes consist of an active site made of a heme-iron center. The iron compound is bound to the protein by a cysteine thiolate molecule. Substrate (s) bind to the active site at the heme group, which induces a conformational change of the enzyme's active site. Reductases are then responsible for electron transfer from NAD (P)H.
