Effects of hispidulin on the activity of human liver cytochrome P450 enzymes

Hispidulin is a flavonoid compound with a variety of pharmacological properties, andhow-ever, whether hispidulin affects the activity of human liver cytochrome P450 (CYP) enzymes remains un-clear.In this study, the inhibitory effects of hispidulin on the eight human liver CYP isoforms (i.e., 1A2, 3A4, 2A6, 2E1, 2D6, 2C9, 2C19, and 2C8) were investigated in vitro using human liver microsomes (HLMs).The results showed that hispidulin inhibited the activity of CYP3A4 and 2E1, with IC50 values of 13.96 and 20.67 muM, respectively, but that other CYP isoforms were not affected. Enzyme kinetic studies showed that hispidulin was not only a non-competitive inhibitor of CYP3A4, but also a competitive inhibitor of CYP2E1, with Ki values of 7.77 and 11.75 muM, respectively. In addition, hispidulin is a time-de-pendent inhibitor for CYP2E1 with Kinact/KI value of 0.026/2.22 muM-1min-1.The in vitro studies of hispidulin with CYP isoforms indicate that hispidulin has the potential to cause pharmacokinetic drug interactions with other co-administered drugs metabolized by CYP3A4 and 2E1. Further clinical studies are also needed to evaluate the significance of this interaction.

Elemental sulfur as a sulfuration agent in the copper-catalyzed C-H bond thiolation of electron-deficient arenes

By utilizing elemental sulfur as the thiolation agent and oxidant, a copper-catalyzed direct C-H bond thiolation of electron-deficient arenes was demonstrated. Various electron-deficient arenes were proved to be suitable for this transformation. Preliminary mechanistic studies indicated that this reaction underwent a radical pathway, in which the trisulfur radical anion (S3-) might play a vital role. Meanwhile, KIE experiments suggested that C-H bond cleavage was not involved in the rate-determining step.

Highly sensitive LC?MS/MS methods for the determination of seven human CYP450 activities using small oral doses of probe-drugs in human

Cocktails composed of several Cytochrome P450 (CYP450)-selective probe drugs have been shown of value to characterize in vivo drug-metabolism activities. Our objective was to develop and validate highly sensitive and selective LC?MS/MS assays allowing the determination of seven major human CYP450 isoenzyme activities following administration of low oral doses of a modified CYP450 probe-drug cocktail in patients. The seven-drug cocktail was composed of caffeine, bupropion, tolbutamide, omeprazole, dextromethorphan, midazolam (all administered concomitantly) and chlorzoxazone (administered separately) to phenotype for CYP1A2, 2B6, 2C9, 2C19, 2D6, 3A4/5 and 2E1, respectively. Serial plasma and urine samples were collected over an 8?h period. The probe-drugs and their respective metabolites were measured in both human plasma and urine, except for omeprazole (plasma only) and chlorzoxazone (urine only). Samples were analyzed by high performance liquid chromatography with heated electrospray ionization tandem mass spectrometry (HPLC-HESI-MS/MS) using a Phenomenex Luna PFP (2) analytical column (3?mum PFP(2) 150?¡Á?3?mm) for chromatographic separation. Optimal detection was achieved based on 3 different analytical methods; (1) isocratic elution with a mobile phase consisting of acetonitrile and water both fortified with 0.01% formic acid for the analysis of bupropion, tolbutamide, chlorzoxazone and their respective metabolites; (2) isocratic elution with a mobile phase composed of acetonitrile and ammonium formate (pH 3; 10?mM) for omeprazole, dextromethorphan, midazolam and their metabolites; (3) for caffeine and paraxanthine, gradient elution using acetonitrile and 0.01% formic acid in water was used. All calibration functions were linear for all probe drugs and metabolites in both matrices over wide analytical ranges. The main advantages of our methods are the use of specific probe drugs available in most countries, the administration of small doses of probe drugs, small volume of plasma required for the analyses and simple and rapid extraction procedures. The methods met all requirements of specificity, sensitivity, linearity, precision and accuracy and stability generally accepted in bioanalytical chemistry. Determination of CYP450 phenotype in patients will permit characterization of their capacities to metabolize drugs through CYP450 under specific conditions at a definite time. This tool will be highly clinically relevant since wide intersubject variability observed in drug response is largely explained by variation in drug metabolism; it will be particularly useful in polymedicated patients with multiple comorbidities. So far, our CYP450 cocktail assays have been successfully applied to phenotype CYP450 activities in patients.

Time of the day dictates the variability of biomarkers of exposure to disinfection byproducts

Non-persistent environmental chemicals (NOPEC) are xenobiotics with short half-lives of elimination (< 7 h). Similar to chronopharmacokinetics, NOPEC metabolism may follow diurnal patterns of cytochrome P450 activity. The role of circadian liver clock in shaping NOPEC metabolism and their concomitant measurements of biomarkers of exposure and effect remains poorly understood in real-life human settings. Metabolic activation (toxication) by CYP2E1 converts trihalomethanes (THM) to harmful metabolites. We investigated the diurnal variation of urinary THM exposures and their metabolism patterns as catalyzed by CYP2E1 redox activity, using the surrogate marker of 4-hydroxynonenal (4HNE). We implemented three time-series trials with adult volunteers conducting specific household cleaning activities at predefined times of a day. Circadia variation of 4HNE was assessed with a cosinor model and its mesor levels increased with THM exposure. The time of exposure within the day dictated the magnitude of urinary THM levels and their toxication effect; in all three trials and relative to urinary THM levels before the activity, lower and higher median THM were measured right after the activity in morning and afternoon/night, respectively. This is consistent with higher reported CYP2E1 redox activity in light/active phase. Population health studies should incorporate time-stamped biomarker data to improve the understanding of chronic disease processes. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 1750-45-4, you can also check out more blogs about1750-45-4

Benzoxazole and benzothiazole amides as novel pharmacokinetic enhancers of HIV protease inhibitors

A new class of benzoxazole and benzothiazole amide derivatives exhibiting potent CYP3A4 inhibiting properties was identified. Extensive lead optimization was aimed at improving the CYP3A4 inhibitory properties as well as overall ADME profile of these amide derivatives. This led to the identification of thiazol-5-ylmethyl (2S,3R)-4-(2-(ethyl(methyl)amino)-N-isobutylbenzo[d]oxazole- 6-carboxamido)-3-hydroxy-1-phenylbutan-2-ylcarbamate (C1) as a lead candidate for this class. This compound together with structurally similar analogues demonstrated excellent ‘boosting’ properties when tested in dogs. These findings warrant further evaluation of their properties in an effort to identify valuable alternatives to Ritonavir as pharmacokinetic enhancers.
