Consumers have recently become more aware of the benefits and risks of using health foods, through information provided by relevant regulatory agencies. While ginkgolide A, B, C, J, and bilobalide, known as constituents of Ginkgo biloba, have shown weak or negligible inhibition of CYP1A2, CYP2C9, and CYP3A in human liver microsomes, other constituents, such as ginkgolic acid I and II, have been reported to inhibit CYP1A2, CYP2C9, and CYP2C19 [6, 7]. The other calculations were performed using Excel (Microsoft, Seattle, MA, USA). 2019 Nov;14(6):621-630. doi: 10.1016/j.ajps.2018.12.003. Wang K, Chen S, Xie W, Wan YJ. Common interactions are associated with the inhibition of drug-metabolizing enzymes, particularly cytochrome P450s (CYPs, P450s). Eur J Clin Pharmacol. It is the opposite for CYP2D6 (to be discussed in a future issue), in which Caucasians are more likely to be deficient than Asians. CAS  Springer Nature. However, the consumption of health foods has increased rapidly, because they are inexpensive and readily available in comparison with FOSHU. tobacco smoke and grapefruit juice) may also act as CYP inducers and inhibitors 2 and 3, Table 2) [12, 13]. CYP2C9 is one of the most abundant CYP enzymes and responsible for the metabolism of over 15% clinical drugs, including oral sulfonylurea hypoglycemics, nonsteroidal anti-inflammatory agents, selective cyclooxygenase-2 inhibitors, antiepileptics, angiotensin II receptor inhibitors and anticoagulants. 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%. Chalasani N, Bonkovsky HL, Fontana R, Lee W, Stolz A, Talwalkar J, et al. 2008;392:1093–108. Ad-P450 cells were incubated in culture medium containing P450 substrate cocktail and test solution (0.5%) or curcumin (10–300 μM) for 5 h. Collected medium was mixed with an equal volume of ethyl acetate containing 0.1 μM nitrazepam (internal standard). Inhibitors - CYP inhibitors reduce the activity of CYP enzymes. 2015;148:1340–52. We therefore developed cells that mimicked the activities of cytochrome P450 1A2 (CYP1A2), CYP2C9, CYP2C19, CYP2D6, and CYP3A4, which strongly contribute to drug metabolism in human hepatocytes, and established a system to assess the inhibitory activity of health foods toward P450-mediated metabolism. Effects of herbal components on cDNA-expressed cytochrome P450 enzyme catalytic activity. In Vitro Cell Dev Biol Anim. 2020 Apr;45(2):173-225. doi: 10.1007/s13318-019-00582-8.

Phenacetin, acetaminophen, dextromethorphan, dextrorphan, furafyllin, and sulfaphenazole were purchased from Sigma-Aldrich (St. Louis, MO, USA). 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. 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. CAS  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 results may provide useful information to predict health food-drug interactions.

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. Drug Metab Dispos. PubMed  CYP2C9 ist am oxidativen Metabolismus verschiedener Arzneimittel in der Phase 1 beteiligt, unter anderem am Metabolismus von NSAR (z.B. We established Ad-P450 cells mimicking the activity levels of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 in human hepatocytes. Constructs of these P450-expressing adenoviruses, Ad-CYP1A2, Ad-CYP2C9, Ad-CYP2C19, and Ad-CYP3A4, were made according to the procedure described [11]. 2014;40:488–99. 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). These results suggest that P450 inhibition by the turmeric-based product could also be associated with ingredients other than curcumin. 2009;24:244–9. Misaka S, Kawabe K, Onoue S, Werba JP, Giroli M, Tamaki S, et al. The Km, Vmax, and IC50 values were determined using Prism software (version 6.0; GraphPad Software Inc., San Diego, CA, USA). Apigenin ; Starfruit juice ; Licochalcone A, a major compound in traditional Chinese herbal licorice ; Caffeic acid, commonly found in plants 5-Hydroxyomeprazole was purchased from Toronto Research Chemical (North York, Canada). 5). Moreover, this system has a valuable advantage, where it can mimic hepatocytes of P450-mediated metabolism, which showed interindividual variations by adjusting the ration of infection amount and species of P450-expressing adenovirus [22]. 1). Of the 172 products, five products [two products having dietary effects (diet, no. 2008;58:206–14. Clin Exp Pharmacol Physiol. Toxicology. All other reagents were of the highest grade available from Wako Pure Chemical Industries (Osaka, Japan) and Sigma-Aldrich. Article  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. Liu Y, Santillo MF, Flynn TJ, Ferguson MS. It can metabolize THC and 11-OH-THC, but a key point is that it only forms certain metabolites (2005 study, 2007 study). We investigated the inhibitory effects of 172 health foods that were recently in circulation in Japan on P450-mediated metabolism using Ad-P450 cells. 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. The CYP2C9 gene is highly polymorphic. 2015;18:316–27. J Biol Chem. 2015 ). CYP2C9 Polymorphism Activity: Frequency in Various Populations 18. Note this is not a exhaustive list of all CYP inhibitors and only the genes CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP3A4 and CYP3A5 are considered. von Moltke LL, Weemhoff JL, Bedir E, Khan IA, Harmatz JS, Goldman P, et al. Silybin inactivates cytochromes P450 3A4 and 2C9 and inhibits major hepatic glucuronosyltransferases. 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. Health foods have been widely sold and consumed in Japan. Most inhibitors of CYP2C9 are competitive inhibitors. Five products [collagen-based (no. Liquid-type health foods were used as test solutions without extraction procedure. 2015;239:1–8. 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. Cite this article. Products that inhibited any P450 by more than 50% were considered to have P450 inhibitory activity. Expression of CYP3A4, CYP2B6, and CYP2C9 is regulated by the vitamin D receptor pathway in primary human hepatocytes. Coleus forskohlii extract- and collagen-based products also inhibit CYP2D6. This may decrease the metabolism of other drugs that are substrates of the enzyme increasing their exposure. 135 and 136) simultaneously inhibited the four P450s except CYP1A2. Int J Mol Sci. We have established a system to assess the inhibitory effects of health foods on P450-mediated metabolism using Ad-P450 cells. 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. These media were collected and metabolites were analyzed by LC-MS/MS. Epub 2019 Jan 16. 2004;32:587–94. We established a comprehensive assessment system to elucidate the effects of health foods on P450-mediated metabolism and identified the inhibitory activity of 34 of 172 health foods toward the drug-metabolizing P450s. Sridar C, Goosen TC, Kent UM, Williams JA, Hollenberg PF. N.D.: not detected. These Increase CYP2C9. Data sharing not applicable to this article as no datasets were generated or analyzed during the current study. The P450s activities in Ad-P450 cells cultured in P450 substrate cocktail and 0.5% extractant (70% ethanol) for 5 h were set to 100%. 2015;45:978–89. This site needs JavaScript to work properly. We simultaneously infected HepG2 cells with five P450-expressing adenoviruses (Ad-CYP1A2, Ad-CYP2C9, Ad-CYP2C19, Ad-CYP2D6, and Ad-CYP3A4) to mimic the activity levels of these P450s in human hepatocytes, and named them Ad-P450 cells. Article  These results suggest that unidentified ingredients might be involved in P450 inhibition, since these two diet products do not include common ingredients other than C. forskohlii extract. Drug Metab Pharmacokinet. Zientek M, Miller H, Smith D, Dunklee MB, Heinle L, Thurston A, et al. Effect of health foods on cytochrome P450-mediated drug metabolism. 2010 Jul 20;130(2):275-83. doi: 10.1016/j.jep.2010.05.002. Based on the product labels, the collagen-based product (no. Ginsenosides Rb1, Rb2, and Rc had limited inhibitory activities on both enzyme reaction systems, whereas the effects of ginkgolides A and B appeared negligible. Table 3.4. Diclofenac, Ibuprofen) Sulfonylharnstoffen (z.B. 2 and 3). The cells were cultured for 72 h and subsequently used as Ad-P450 cells. Correspondence to However, there are few reports concerning their P450 inhibitory activities. Desolvation line temperature and heat block temperature was 250 and 400 °C, respectively. A vitamin-, an isoflavone, and a vitamin/mineral-based product (no. 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 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. … Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. The cells were seeded in type I collagen-coated 48-well plate at 8.5 × 104 cells/well. 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. Epub 2020 Feb 7. NLM 2020 May;44(3):399-404. doi: 10.1016/j.jgr.2020.02.001. Oligonucleotides were commercially synthesized by Fasmac (Atsugi, Japan). The resulting solution was centrifuged at 3500 × g for 15 min and the supernatant was used as a test solution. 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.
