Although many reports have provided useful information on the safe and effective use of health foods … 15, 62, and 131) simultaneously inhibited two P450s (CYP1A2 and CYP2C9). (e) Strong inhibitor of CYP2C19 and moderate inhibitor of CYP2C9 and CYP3A. Reporting of adverse effects has also increased in association with the expansion of the health food market . Takikawa H, Murata Y, Horiike N, Fukui H, Onji M. Drug-induced liver injury in Japan: an analysis of 1676 cases between 1997 and 2006. Toxicol Lett. Accessed 24 Dec 2015. Desolvation line temperature and heat block temperature was 250 and 400 °C, respectively. Note: CYP3A4 is the main enzyme that metabolizes Gleevec and therefore effects may be more pronounced that those … Our results support the previous study, since the inhibition of CYP1A2 by two sesamin-based products was weaker than that of other P450s. These results suggest that Ad-P450 cells are useful for the assessment of P450-mediated drug metabolism, and drug-drug or health food-drug interactions. Although further study is needed to elucidate the P450 inhibition by vitamin-based product, the use of excessive amounts of water-soluble vitamins should be avoided to prevent health food-drug interactions. 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. Venlafaxine: in vitro inhibition of CYP2D6 dependent imipramine and desipramine metabolism; comparative studies with selected SSRIs, and effects on human hepatic CYP3A4, CYP2C9 and CYP1A2.

The activity levels are shown as means ± SD (n = 3). 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. Asian J Pharm Sci. For example, green tea extract has been reported to inhibit CYP2C9, CYP2D6, and CYP3A4 in human liver microsomes . Specifically, it forms metabolites in the pathway leading to excretion into … 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. Silibinin has been reported to inhibit CYP2C9 and CYP3A4 through mechanism-based inhibition (MBI) . High-throughput cytochrome P450 cocktail inhibition assay for assessing drug-drug and drug-botanical interactions. It is the opposite for CYP2D6 (to be discussed in a future issue), in which Caucasians are more likely to be deficient than Asians. Thus, it is difficult to deduce the effects of health foods on P450-mediated metabolism solely from the assessment of their main ingredients. 5). The activity levels are shown as means ± SD (n = 3). 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. 1997 Jun;43(6):619-26. doi: 10.1046/j.1365-2125.1997.00591.x. This report is the first to investigate the P450 inhibitory effects of a large number of health foods under the same conditions. Pan Y, Abd-Rashid BA, Ismail Z, Ismail R, Mak JW, Pook PC, Er HM, Ong CE. Note this is not a exhaustive list of all CYP inhibitors and only the genes CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP3A4 and CYP3A5 are considered. 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%. The herbal compounds investigated were capable of inhibiting CYP2C9 and CYP3A4 catalytic activities, but the potencies differed. Article Although most health foods contain ingredients that promote health and improve health-related conditions, the effectiveness of these products has not been proven. We investigated the inhibitory effects of 172 health foods, whose uses in Japan were confirmed in our previous survey , on P450-mediated metabolism in Ad-P450 cells. 2010;38:2117–23. Jpn J Pharm Health Care Sci. Omeprazol, Fluconazol und Voriconazol. The LC-MS/MS conditions were shown in Table 1. It was indicated that the noncompetitive binding site of 6-hydroxyflavone is the reported allosteric binding site of the CYP2C9 enzyme. Aoyama K, Yoshinari K, Kim HJ, Nagata K, Yamazoe Y. In addition, nineteen other products were found to inhibit one of the five P450s. Most inhibitors of CYP2C9 are competitive inhibitors. In this study, 7 herbal components ginsenosides Rb1, Rb2, Rc, and Rd (from ginseng quercetin) ginkgolides A and B (from ginkgo biloba) were investigated for their inhibitory effects on hepatic CYP2C9 and CYP3A4 catalytic activities in human liver microsomes. Diagnostic errors can occur due to rare sequence variations. 2004;32:587–94. 135 and 136) simultaneously inhibited the four P450s except CYP1A2. COVID-19 is an emerging, rapidly evolving situation. CYP2C9 has an important role in the metabolism of many Nonsteroidal anti-inflammatory drugs … About 3% to 5% of Caucasians are poor metabolizers for CYP2C19?that is, they lack functioning genes for the synthesis of CYP2C19. 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. Therefore, our results demonstrated that 34 (19.8%) of 172 health foods have P450 inhibitory activities. 5). 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. 2019 Nov;14(6):621-630. doi: 10.1016/j.ajps.2018.12.003. 2004;19:280–9. 5-Hydroxyomeprazole was purchased from Toronto Research Chemical (North York, Canada). 29–38 and 151) did not. Clotrimazole: A topical broad-spectrum antifungal agent used for the treatment of a wide variety of dermatophyte infections and candidiasis. Article 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. Nebulizer gas flow rate and drying gas flow rate were 3 and 15 L/min, respectively. It was recently reported that a metabolite of rutaecarpine, a principal constituent of Evodia rutaecarpa, strongly inhibits P450s , suggesting that health food-drug interactions could be caused by P450 inhibition through MBI. However, health foods that are on the market in Japan contain a number of ingredients, and such products may contain impurities.
