Article  145 and 146)] simultaneously inhibited three P450s (CYP1A2, CYP2C9/CYP2D6, and CYP3A4). Cytochrome P-450 CYP2C9 Inhibitors Accession Number DBCAT000489 (DBCAT004132) Description. Koike M, Otsu F, Sakakibara J, Goto N. The current status of health food- or supplement-related adverse health effects. 4 and are summarized in Table 3. Common interactions are associated with the inhibition of drug-metabolizing enzymes, particularly cytochrome P450s (CYPs, P450s). The two diet products (no. adapted from the US Food and Drug Administration (FDA) prescribing information as used in previous studies and Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines.11-14 Notably, no participants were ho-mozygous for CYP2C9*3, and no participants carried the CYP2C9*4 variant, which can interfere with detection of CYP2C9*3. The open reading frames of CYP1A2, CYP2C9, CYP2C19, and CYP3A4 were amplified by PCR from cDNA obtained from human hepatocytes by using primers specific for CYP1A2 (forward: 5′-CACCATGGCATTGTCCCAGTCTGTTC-3′; reverse: 5′-TCAGTTGATGGAGAAGCGCAGCCG-3′), CYP2C9 (forward: 5′-CACCATGGATTCTCTTGTGGTCCTTG-3′; reverse: 5′-TCAGACAGGAATGAAGCACAGCTGGTAG-3′), CYP2C19 (forward: 5′-CACCATGGATCCTTTTGTGGTCCTTGTG-3′; reverse: 5′-TCAGACAGGAATGAAGCACAGCTGA-3′), and CYP3A4 (forward: 5′-CACCATGGCTCTCATCCCAGACTTGGC-3′; reverse: 5′-TCAGGCTCCACTTACGGTGCCATC-3′), respectively. 5). 2008;392:1093–108. However, the consumption of health foods has increased rapidly, because they are inexpensive and readily available in comparison with FOSHU. CYP2C9 is involved in many drug interactions.Some of the substrates that warrantparticular attention are warfarin,phenytoin, and oral hypoglycemics.Some of the more potent CYP2C9inhibitors include amiodarone, fluorouracil,metronidazole, miconazole(especially systemic use), and sulfamethoxazole(usually combined withtrimethoprim). Curcumin is a known constituent of turmeric and a P450 inhibitor [14]. Delavirdine, a non-nucleoside inhibitor of HIV-1 reverse transcriptase, is metabolized primarily through desalkylation catalyzed by CYP3A4 and CYP2D6 and by pyridine hydroxylation catalyzed by CYP3A4. 168)] simultaneously inhibited the five P450s by more than 50%. In this study, we established a system to assess the inhibitory effects of health foods on P450-mediated metabolism using Ad-P450 cells.

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. Retinoids induce cytochrome P450 3A4 through RXR/VDR-mediated pathway. Cytochrome 2C9 inhibition. von Moltke LL, Weemhoff JL, Bedir E, Khan IA, Harmatz JS, Goldman P, et al. This site needs JavaScript to work properly. 2007;235:83–91. Although many reports have provided useful information on the safe and effective use of health foods … … Fluvoxamin ist ein starker Inhibitor für 1A2 und 2C19 sowie ein mittelmäßiger Inhibitor für 2C9 und 3A4.  |  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. Δ = Strong Inhibitor, = Moderate Inhibitors, = Weak Inhibitors Furthermore, the results of the inhibition of CYP2D6 in Ad-P450 cells were consistent with those obtained using Ad-CYP2D6-infected cells in our previous study [8]. Constructs of these P450-expressing adenoviruses, Ad-CYP1A2, Ad-CYP2C9, Ad-CYP2C19, and Ad-CYP3A4, were made according to the procedure described [11]. The Km, Vmax, and IC50 values were determined using Prism software (version 6.0; GraphPad Software Inc., San Diego, CA, USA). Sasaki, T., Sato, Y., Kumagai, T. et al. Thus, it is difficult to deduce the effects of health foods on P450-mediated metabolism solely from the assessment of their main ingredients. 15) does not contain vitamin A and vitamin D, while the amounts of water-soluble vitamins, such as vitamins B1, B2, B6, B12, and pantothenic acid, were higher than those in other vitamin-based products. Quinidine was purchased from Tokyo Chemical Industry (Tokyo, Japan). The other calculations were performed using Excel (Microsoft, Seattle, MA, USA). Li G, Huang K, Nikolic D, van Breemen RB. 4). 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. Fluconazole inhibition of CYP2C9 can result in markedly elevated levels of warfarin, with a resultant risk of hemorrhage. Springer Nature. 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. These media were collected and metabolites were analyzed by LC-MS/MS. 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. The column oven temperature was maintained at 40 °C. Google Scholar. HHS 2010 Jul 20;130(2):275-83. doi: 10.1016/j.jep.2010.05.002. Publically available sources such as the www.pharmvar.org or www.pharmgkb.org provide guidance on phenotype predictions and allele frequencies. Another 29 products were also confirmed to inhibit one or more P450s. Missense variant CYP2C9∗3 is also known to be significantly associated with phenytoin-related ADR in Asian people as a result of delayed clearance and accumulation of metabolites. After 12 h, the cell medium was changed with culture medium (Biopredic International) containing P450 substrate cocktail (100 μM phenacetin, 25 μM diclofenac, 10 μM omeprazole, 10 μM dextromethorphan, and 10 μM midazolam) and then the cells were incubated for 24 h. HepG2 cells were purchased from RIKEN cell Bank (Tsukuba, Japan) and were cultured in Dulbecco’s modified Eagle’s medium (Wako Pure Chemical Industries) supplemented with 10% fetal bovine serum (Biowest, Miami, FL, USA), non-essential amino acids (Thermo Fisher Scientific, Maltham, MA, USA), and antibiotic-antimycotic (Thermo Fisher Scientific) under 5% CO2-95% air at 37 °C. 65 and 66), one turmeric-based product (no. We determined the Km values of P450 substrates and IC50 values of P450 inhibitors in Ad-P450 cells. Previous in vitro work has demonstrated that genotype-dependent inhibition of CYP2C9 mediated flurbiprofen metabolism, suggesting the possibility of genotype-dependent inhibition interactions in vivo. The activity levels of P450s in Ad-P450 cells and human hepatocytes were calculated via simultaneous liquid chromatography/tandem mass spectrometry analysis utilizing a P450 substrate cocktail. The safety, immunological benefits, and efficacy of ginseng in organ transplantation. Accessed 24 Dec 2015. 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. However, due to their high cost and lot-to-lot variations in drug metabolism, it is difficult to continuously obtain human primary hepatocytes that have the same metabolic activities, and therefore these cells are unsuitable for high-throughput testing. 2015;18:316–27.

In order to comprehensively elucidate health food-drug interactions, we developed Ad-P450 cells mimicking the activity levels of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 in human hepatocytes and established a P450 inhibition assessment system. There are five “new” drugs as CYP2C9 inhibitors of potential clinical significance, three of them kinase inhibitors (ceritinib, sonidegib, and vemurafenib). National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Of the 172 health foods, five products (two products having dietary effects, one turmeric-based product, one collagen-based product, and one propolis-containing product) simultaneously inhibited the five P450s by more than 50%. Drugs and compounds which inhibit or antagonize the biosynthesis or actions of CYTOCHROME P-450 CYP2C9. In vitro and animal pharmacokinetic data support the possibility of CYP3A4/CYP2C9 inhibition by pomegranate juice; however, the human relevance for drug-drug interaction was not established based on the limited case studies. 2004;32:587–94. 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. However, health foods that are on the market in Japan contain a number of ingredients, and such products may contain impurities. The herbal compounds investigated were capable of inhibiting CYP2C9 and CYP3A4 catalytic activities, but the potencies differed. Drocourt L, Ourlin JC, Pascussi JM, Maurel P, Vilarem MJ. Chalasani N, Bonkovsky HL, Fontana R, Lee W, Stolz A, Talwalkar J, et al. Terms and Conditions, Drug Metab Pharmacokinet. Drug Metab Dispos. Aoyama K, Yoshinari K, Kim HJ, Nagata K, Yamazoe Y. However, this established assessment system is easily applicable to health food-drug interactions testing for many health foods, because Ad-P450 cells are inexpensive with little to no lot-to-lot variations. © 2021 BioMed Central Ltd unless otherwise stated. Epigallocatechin gallate, the most abundant catechin in green tee, is also a potent inhibitor of CYP3A in human liver and intestinal microsomes [5]. Effect of health foods on P450-mediated metabolism in Ad-P450 cells. tobacco smoke and grapefruit juice) may also act as CYP inducers and inhibitors 4-hydroxydiclofenac and 1-hydroxymidazolam were purchased from Becton Dickinson (Franklin Lakes, NJ, USA). Silybin inactivates cytochromes P450 3A4 and 2C9 and inhibits major hepatic glucuronosyltransferases. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. 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. However, there are few reports concerning their P450 inhibitory activities. Preparation of Ad-CYP2D6 was previously described [8]. 125) also inhibited the five P450s, with CYP2C9 being the most inhibited. Interaction studies with inhibitors of CYP3A4 have not demonstrated significant changes in the pharmacokinetics of losartan or E3174. We investigated the inhibitory effects of 172 health foods, whose uses in Japan were confirmed in our previous survey [8], on P450-mediated metabolism in Ad-P450 cells. The inhibition by forskolin and collagen had not been previously reported. Article  Herbal medicines are widely consumed by patients in different clinical settings in the United States and all over the world. 2020 May;44(3):399-404. doi: 10.1016/j.jgr.2020.02.001. We recently reported the effects of health foods that are available in Japan on CYP2D6-mediated metabolism [8]. Rifampicin. Of the 172 health food products tested, five products simultaneously inhibited all the five P450s, and another 29 products inhibited at least one of the P450s. Diclofenac, Ibuprofen) Sulfonylharnstoffen (z.B. Ginsenoside Rd also had significant inhibitory potency on both CYP2C9- and CYP3A4-mediated index reactions with IC(50) values of 105 and 62 micromol/L, respectively. Part of After 48 h, the cells were simultaneously infected with Ad-CYP1A2 at 5 multiplicity of infection (MOI), Ad-CYP2C9 at 1 MOI, Ad-CYP2C19 at 2 MOI, Ad-CYP2D6 at 0.05 MOI, and Ad-CYP3A4 at 10 MOI. 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]. 62) and one vitamin-based (no. 2002 Feb;57(12):847-51. doi: 10.1007/s00228-001-0399-0. 1). There has been an increase in reports of adverse effects in association with the expanding health food market. We have established a system to assess the inhibitory effects of health foods on P450-mediated metabolism using Ad-P450 cells. J Pharm Pharmacol. We determined the Km values for typical P450 reactions and IC50 values of representative P450 inhibitors in the Ad-P450 cells. We confirmed that one isoflavone-based (no. 5-Hydroxyomeprazole was purchased from Toronto Research Chemical (North York, Canada). Google Scholar. It is concluded that the components of ginseng and ginkgo biloba screened are capable of inhibiting CYP2C9- and CYP3A4-mediated metabolic reactions. 2006 Sep;33(9):813-5. doi: 10.1111/j.1440-1681.2006.04445.x. NIH The CYP2C9 gene is highly polymorphic. Although the P450 activities in HepG2 cells infected with five P450-expressing adenoviruses were slightly lower in comparison with those in human hepatocytes, the ratios of the activities of each P450 were almost identical between these two cells (Fig. COVID-19 is an emerging, rapidly evolving situation. The residues were dissolved in acetonitrile containing 0.1% acetic acid and the solutions were subjected to liquid chromatography/tandem mass spectrometry (LC-MS/MS) analysis. We established a comprehensive assessment system to investigate the effects of health foods on P450-mediated metabolism and found that 34 of the 172 health foods have the potential to inhibit human P450 activities. 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. Omeprazol, Fluconazol und Voriconazol. The only “old” inhibitor is the widely used antiarrhythmic amiodarone, which is used in research projects as an example of a drug with a very long half-life, complex kinetics and multiple potential interactions (McDonald et al. Inhibition of human cytochromes P450 by components of Ginkgo biloba. Lim SW, Luo K, Quan Y, Cui S, Shin YJ, Ko EJ, Chung BH, Yang CW. Kiyoshi Nagata. Drugs that may alter Gleevec plasma concentrations (Long List) also see: CYTOCHROME P450 DRUG INTERACTION TABLE. 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. 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. Curr Top Med Chem. The specific P450 inhibitors used showed concentration-dependent inhibition, and the IC50 values are shown in Table 2. 1). CYP2C9 Inhibition CYP2C9 is an enzyme found mainly in your liver. Nebulizer gas flow rate and drying gas flow rate were 3 and 15 L/min, respectively. Deswegen führte die Einnahme von Fluvoxamin zu einer Inhibition des Abbaus von Diazepam und hiermit zu einem erhöhten Diazepam-Plasmaspiegel mit begleitender erhöhter Sedierung der Patientin als Folg… Drug Metab Pharmacokinet. 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. Induktoren sind Rifampicin, Prednisolon, Hyperforin u.v.a.
