The cells were seeded in type I collagen-coated 48-well plate at 8.5 × 104 cells/well. Life Sci. In the current study, flurbiprofen was used as a probe substrate and fluconazole as a prototypical inhibitor to investigate whether genotype-dependent inhibition of CYP2C9 occurs in vivo. Part of Zou L, Harkey MR, Henderson GL. Oligonucleotides were commercially synthesized by Fasmac (Atsugi, Japan). COVID-19 is an emerging, rapidly evolving situation. CYP2C19 catalyzes the metabolism of several drugs, including proton pump inhibitors (PPIs) (e.g., omeprazole, lansoprazole, pantoprazole), antidepressants (e.g., citalopram and amitriptyline), antiplatelet drugs (e.g., clopidogrel), antifungals (e.g., voriconazole), and anticancer compounds (e.g., cyclophosphamide). The Michaelis-Menten equation was used to calculate the Km and Vmax values from the metabolic reaction rates of the five P450s (Table 2). NIH Kinetic analysis of P450-mediated metabolism in Ad-P450 cells. Our results may provide useful information to predict health food-drug interactions. 15, 62, and 131) simultaneously inhibited two P450s (CYP1A2 and CYP2C9). 36), diet (no. Activity levels of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 in Ad-P450 cells and human hepatocytes. Kiyoshi Nagata. It was recently reported that a metabolite of rutaecarpine, a principal constituent of Evodia rutaecarpa, strongly inhibits P450s [16], suggesting that health food-drug interactions could be caused by P450 inhibition through MBI. By using this website, you agree to our 2015;239:1–8. Consumers have recently become more aware of the benefits and risks of using health foods, through information provided by relevant regulatory agencies. J Biol Chem. N.D.: not detected. The metabolites of both reactions were measured by high-performance liquid chromatography and used as indicators of whether enzymes were inhibited or unaffected by these agents. We established Ad-P450 cells mimicking the activity levels of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 in human hepatocytes. Google Scholar. Cite this article. Rucaparib showed mixed inhibition of CYP2C9 (competitive Ki = 67 μM; uncompetitive Ki = 31.5 μM), as well as reversible CYP3A inhibition (half maximal inhibitory concentration = 17.2 μM). Correspondence to A vitamin-, an isoflavone, and a vitamin/mineral-based product (no. Epub 2020 Feb 7. 2004;32:587–94. TS and KN contributed new reagents or analytic tools. Foods with health claims and so-called ‘health foods’ have been widely sold and consumed in Japan. The activity levels are shown as means ± SD (n = 3). Long List of Inhibitors and Inducers of CYP3A4 and CYP2D6 LRG Team 2018-07-09T14:46:40-04:00. These values were approximately equivalent to those obtained in previous studies (Figs. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. It was indicated that the noncompetitive binding site of 6-hydroxyflavone is the reported allosteric binding site of the CYP2C9 enzyme. Curr Top Med Chem. The limit of quantitation is 18.90 ng/mL for acetaminophen, 39.02 ng/mL for 4′-hydroxydiclofenac, 0.24 ng/mL for 5-hydroxyomeprazole, 0.25 ng/mL for dextrorphan, and 2.14 ng/mL for 1′-hydroxymidazolam. Most inhibitors of CYP2C9 are competitive inhibitors. Quercetin showed marked inhibitory effects on both tolbutamide 4-methylhydroxylation and testosterone 6beta-hydroxylation with IC(50) values of 35 and 38 micromol/L, respectively. California Privacy Statement, Therefore, our results demonstrated that 34 (19.8%) of 172 health foods have P450 inhibitory activities.
