About 3% to 5% of Caucasians are poor metabolizers for CYP2C19?that is, they lack functioning genes for the synthesis of CYP2C19. 2017 Dec 23;19(1):25. doi: 10.3390/ijms19010025. Limitations: Only the targeted CYP2C8 and CYP2C9 variants will be detected by this panel, and assumptions about phase and content are made to assign alleles. 2015;239:1–8. NIH Our results showed that five products (two diet products, one turmeric-based product, one collagen-based product, and one propolis-containing product) inhibited the five P450s by more than 50% (Fig. Part of Health food-drug interactions are a particular concern from the viewpoint of safe and effective use of health foods. Journal of Pharmaceutical Health Care and Sciences We therefore believe that the development of a P450 inhibition screening system for complete health food products, rather than their main ingredients, may lead to more appropriate use of the products. The mobile phase consisted of acetonitrile containing 0.1% acetic acid and water containing 0.1% acetic acid (85:15) with a flow rate of 200 μL/min. Of the five products that simultaneously inhibited the five P450s, we further examined the effects of their ingredients in the turmeric-based products on P450-mediated metabolism. Consumers have recently become more aware of the benefits and risks of using health foods, through information provided by relevant regulatory agencies. Phenacetin, acetaminophen, dextromethorphan, dextrorphan, furafyllin, and sulfaphenazole were purchased from Sigma-Aldrich (St. Louis, MO, USA). Google Scholar. CYP2C9 has an important role in the metabolism of many Nonsteroidal anti-inflammatory drugs … The activity levels are shown as means ± SD (n = 3). After shaking, the mixtures were centrifuged at 2500 × g for 10 min and the supernatants were evaporated to dryness at 60 °C in a block incubator. The chromatographic separation was performed on Xterra MS C18 columns (2.1 mm × 100 mm, 5 μm) (Waters, Milford, MA, USA). These results suggest that P450 inhibition by the turmeric-based product could also be associated with ingredients other than curcumin. The other calculations were performed using Excel (Microsoft, Seattle, MA, USA). 1). Fluvoxamin ist ein starker Inhibitor für 1A2 und 2C19 sowie ein mittelmäßiger Inhibitor für 2C9 und 3A4.

WebMD provides information about interactions between Ibuprofen-Glycerin Oral and selected-nsaids-selected-cyp2c9-inhibitors. Ad-P450 cells were incubated in culture medium containing P450 substrate cocktail and curcumin (10–300 μM) for 5 h. These media were collected and metabolites were analyzed by LC-MS/MS. Our findings suggest that quercetin and ginsenoside Rd have the potential to interact with conventional medicines that are metabolized by CYP2C9 and CYP3A4 in vivo. All of the usual enzymeinducers, such as barbiturates, carbamazepine,and rifampin, can substantiallyincrease CYP2C9 activity. Silibinin has been reported to inhibit CYP2C9 and CYP3A4 through mechanism-based inhibition (MBI) [15]. Ad-P450 cells were incubated in culture medium containing P450 substrate cocktail and test solution (0.5%) for 5 h. These media were collected and metabolites were analyzed by LC-MS/MS. Diazepam ist hauptsächlich ein Substrat von CYP2C19 wird aber auch über CYP3A4 metabolisiert. 2013;14:134–43 (in Japanese). The ionization mode used was positive in the multiple reaction monitoring. von Moltke LL, Weemhoff JL, Bedir E, Khan IA, Harmatz JS, Goldman P, et al. Kinetic analysis of P450-mediated metabolism in Ad-P450 cells. It is also an irreversible inhibitor of CYP3A4. Thus, it is difficult to deduce the effects of health foods on P450-mediated metabolism solely from the assessment of their main ingredients. While health food-drug interactions are a particular concern from the viewpoint of safe and effective use of health foods, information regarding such interactions is limited owing to the lack of established methods to assess the effects of health food products on drug metabolism. Based on the data from our previous survey [8], we investigated the effects of health foods, for which actual use in Japan has been confirmed, on the five P450s. (e) Strong inhibitor of CYP2C19 and moderate inhibitor of CYP2C9 and CYP3A. Wang K, Chen S, Xie W, Wan YJ. There are five “new” drugs as CYP2C9 inhibitors of potential clinical significance, three of them kinase inhibitors (ceritinib, sonidegib, and vemurafenib). We investigated the inhibitory effects of 172 health foods that were recently in circulation in Japan on P450-mediated metabolism using Ad-P450 cells. J Ginseng Res. 2004;32:587–94. A turmeric-based product (no. Herbal medicines are widely consumed by patients in different clinical settings in the United States and all over the world. The activity levels of CYP1A2 (phenacetin O-deethylation activity), CYP2C9 (diclofenac 4′-hydroxylation activity), CYP2C19 (omeprazole 5-hydroxylation activity), CYP2D6 (dextromethorphan O-demethylation activity), and CYP3A4 (midazolam 1′-hydroxylation activity) in human hepatocytes were calculated via simultaneous LC-MS/MS analysis utilizing the P450 substrate cocktail. This work was supported by a Health and Labor Sciences Research Grant for Research on Food Safety (No. PubMed  Effect of health foods on cytochrome P450-mediated drug metabolism. Furthermore, it is of great importance to assess the effects of health foods on the five P450s that most strongly contribute to drug metabolism in human livers in order to obtain beneficial and fundamental information under the current situation where there is limited scientific evidence regarding health food-drug interactions. Long List of Inhibitors and Inducers of CYP3A4 and CYP2D6 LRG Team 2018-07-09T14:46:40-04:00. CYP2C9 Polymorphism Activity: Frequency in Various Populations 18. The clearance of CYP2C9-processed drugs is approximately doubled with rifampicin . Reporting of adverse effects has also increased in association with the expansion of the health food market [1]. Foods with health claims and so-called ‘health foods’ have been widely sold and consumed in Japan. HHS Expression of CYP3A4, CYP2B6, and CYP2C9 is regulated by the vitamin D receptor pathway in primary human hepatocytes. Based on these data, we simultaneously infected HepG2 cells with Ad-CYP1A2 (5 MOI), Ad-CYP2C9 (1 MOI), Ad-CYP2C19 (2 MOI), Ad-CYP2D6 (0.05 MOI), and Ad-CYP3A4 (10 MOI) to mimic the activity levels of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 in human hepatocytes. These results show that the Ad-P450 cells are useful tools to assess drug metabolism and health food-drug interactions. We determined the Km values for typical P450 reactions and IC50 values of representative P450 inhibitors in the Ad-P450 cells. We established Ad-P450 cells mimicking the activity levels of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 in human hepatocytes. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. 2 and 3, Table 2) [12, 13]. In this study, we have utilized hepatocellular carcinoma cells (HepG2 cells) and P450-expressing adenoviruses to establish cells (named Ad-P450 cells) that mimic the activities of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4, which strongly contribute to human drug metabolism in human hepatocytes [10]. Zhang FL, He X, Zhai YR, He LN, Zhang SC, Wang LL, et al. The cells (Ad-P450 cells) were cultured for 72 h and then incubated in culture medium containing P450 substrate cocktail for 5 h. Human cryopreserved primary hepatocytes seeded in type I collagen-coated 48-well plate at a density of 8.5 × 104 cells/well were incubated with culture medium containing P450 substrate cocktail for 24 h.

CYP2C9 Inhibition CYP2C9 is an enzyme found mainly in your liver. Quinidine was purchased from Tokyo Chemical Industry (Tokyo, Japan). A kinase inhibitor used in the treatment of unresectable liver carcinoma and advanced renal carcinoma. High-throughput cytochrome P450 cocktail inhibition assay for assessing drug-drug and drug-botanical interactions. To investigate the properties of Ad-P450 cells, we performed kinetic analyses using P450 substrates and calculated IC50 values for specific representative P450 inhibitors (CYP1A2, furafylline; CYP2C9, sulfaphenazole; CYP2C19, ticlopidine; CYP2D6, quinidine; CYP3A4, ketoconazole) in Ad-P450 cells (Figs. 2006 Sep;33(9):813-5. doi: 10.1111/j.1440-1681.2006.04445.x. Health foods were purchased from Japanese retail markets. The cells were incubated in culture medium containing P450 substrate cocktail for 5 h. Ad-P450 cells were incubated in culture medium containing phenacetin (2.5–100 μM), diclofenac (0.5–20 μM), omeprazole (0.25–10 μM), dextromethorphan (1–50 μM), or midazolam (0.25–10 μM) for 5 h. In P450 inhibition assessments, Ad-P450 cells were incubated in culture medium containing P450 substrate cocktail and each typical P450 inhibitors (furafylline for CYP1A2 [0.05–30 μM], sulfaphenazole for CYP2C9 [0.01–10 μM], ticlopidine for CYP2C19 [0.3–300 μM], quinidine for CYP2D6 [0.01–10 μM], or ketoconazole for CYP3A4 [0.01–10 μM]) for 5 h. Recommended daily dose of health foods (tablet, capsule, and powder) was incubated in 10 mL of 70% ethanol for 2 h at 37 °C. In contrast to the assessment of health food-drug interactions using human hepatocytes, assessment using Ad-P450 cells might not provide an accurate prediction of the interaction because of the limited number of P450s expressed in Ad-P450 cells. Although most health foods contain ingredients that promote health and improve health-related conditions, the effectiveness of these products has not been proven. More than 50 single nucleotide polymorphisms (SNPs) have been described in the regulatory and coding regions of the CYP2C9 gene, some of them are associated with reduced enzyme activity compared with wild type in vitro. 2013;28:244–9.
