Quetiapine Fumarate 81-91 myeloperoxidase Homo sapiens 151-166 35575633-4 2022 The interaction of quetiapine and clozapine with MPO and MPO chlorination activity was studied using UV-vis spectrophotometry. Quetiapine Fumarate 19-29 myeloperoxidase Homo sapiens 57-60 35575633-0 2022 Neutrophil Myeloperoxidase-Mediated N-Demethylation of Quetiapine Leads to N-Desalkylquetiapine, a Pharmacologically Active Cytochrome P450 Metabolite. Quetiapine Fumarate 55-65 myeloperoxidase Homo sapiens 11-26 35575633-2 2022 Neutrophil myeloperoxidase (MPO) metabolism of quetiapine is not well-studied, but is metabolized by cytochrome P450. Quetiapine Fumarate 47-57 myeloperoxidase Homo sapiens 11-26 35575633-2 2022 Neutrophil myeloperoxidase (MPO) metabolism of quetiapine is not well-studied, but is metabolized by cytochrome P450. Quetiapine Fumarate 47-57 myeloperoxidase Homo sapiens 28-31 35575633-3 2022 Based on structural similarity to clozapine, we hypothesized that quetiapine can be metabolized by MPO and that there is overlap between cytochrome P450 and MPO metabolism of quetiapine. Quetiapine Fumarate 66-76 myeloperoxidase Homo sapiens 99-102 35575633-3 2022 Based on structural similarity to clozapine, we hypothesized that quetiapine can be metabolized by MPO and that there is overlap between cytochrome P450 and MPO metabolism of quetiapine. Quetiapine Fumarate 175-185 myeloperoxidase Homo sapiens 157-160 35575633-4 2022 The interaction of quetiapine and clozapine with MPO and MPO chlorination activity was studied using UV-vis spectrophotometry. Quetiapine Fumarate 19-29 myeloperoxidase Homo sapiens 49-52 35575633-6 2022 In the presence of quetiapine, MPO compound II accumulated for about 7.5 min, whereas in the presence of clozapine, MPO compound II was not observed as it was rapidly reduced back to the resting state. Quetiapine Fumarate 19-29 myeloperoxidase Homo sapiens 31-34 35575633-7 2022 Increasing quetiapine concentrations resulted in a decrease in MPO chlorination activity, while the opposite result was found in the case of clozapine. Quetiapine Fumarate 11-21 myeloperoxidase Homo sapiens 63-66 35575633-10 2022 The MPO-catalyzed hydroxylated and dealkylated metabolites of quetiapine and hydroxylated metabolites of clozapine were observed from the LC-MS analyses, particularly when Cl- was included in the reaction. Quetiapine Fumarate 62-72 myeloperoxidase Homo sapiens 4-7 35575633-13 2022 In conclusion, MPO/H2O2/Cl- was shown to metabolize quetiapine to S-oxidation and P450-like dealkylation products, and quetiapine metabolites were generally less reactive than clozapine.
