A liquid?chromatography-tandem mass spectrometry analysis of nine cytochrome P450 probe drugs and their corresponding metabolites in human serum and urine

Cocktail phenotyping using specific probe drugs for cytochrome P450 (CYP) enzymes provides information on the real-time activity of multiple CYPs. We investigated different sample preparation techniques and validated a liquid?chromatography-tandem mass spectrometry (LC-MS/MS) method with simple protein precipitation for the analysis of nine CYP probe drugs and their metabolites in human serum and urine. Specific CYP probe drugs (melatonin, CYP1A2; nicotine, CYP2A6; bupropion, CYP2B6; repaglinide, CYP2C8; losartan, CYP2C9; omeprazole, CYP2C19 and CYP3A4; dextromethorphan, CYP2D6; chlorzoxazone, CYP2E; midazolam, CYP3A4) and their main metabolites, with the exception of 3?-hydroxyrepaglinide, were quantified in human serum and urine using the developed LC-MS/MS method. The analytical method was fully validated showing high selectivity, linearity, acceptable accuracy (85?115?%) and precision (2?19?%) and applied to a pharmacokinetic study in four healthy volunteers after oral administration of drugs given as a cocktail. All probe drugs and their metabolites (totally 19 analytes) were detected and quantified from human serum and urine over the time range of 1 to 6?h after oral administration. Therefore, the proposed method is applicable for drug interaction and CYP phenotyping studies utilizing?a cocktail approach. [Figure not available: see fulltext.]

Pd/PTABS: Low Temperature Etherification of Chloroheteroarenes

A mild, general, and highly efficient catalytic etherification protocol for chloroheteroarenes was developed using the Pd/PTABS catalytic system. The protocol is selective for the etherification of chloroheteroarenes using a large variety of electron-rich and electron-deficient phenol bearing synthons which include inter alia biologically and commercially important estrone, estradiol, tyrosine, and several other molecules. The mildness of the new protocol is expected to be beneficial for the synthesis of complex drugs and drug intermediates offering late-stage modification of bioactive compounds.

BPNN-QSTR Modeling to Develop Isosteres as Sulfur-Free, Anti-Wear Lubricant Additives

The principle of isosterism was employed to design low- or zero-sulfur anti-wear lubricant additives. Thiobenzothiazole compounds and 2-benzothiazole-S-carboxylic acid esters were employed as templates. Sulfur in the thiazole ring or in the branched chain was exchanged with oxygen, CH2, or an NH group. Similarly, the template’s benzimidazole ring was replaced with a quinazolinone group. Quantitative structure tribo-ability relationship (QSTR) models by back propagation neural network (BPNN) method were used to study correlations between additive structures and their anti-wear performance. The features of rubbing pairs with different additives were identified by energy dispersive spectrometer-scanning electron microscope analysis. A wide range of samples showed that sulfur substitution in additive molecules was found to be reasonable and feasible. Combined effects of the anti-wear additive and the base oil were able to improve antiwear performance.

Construction of a polyheterocyclic benzopyran library with diverse core skeletons through diversity-oriented synthesis pathway

In this study, a divergent and practical solid-phase parallel diversity-oriented synthesis (DOS) strategy was successfully applied for the construction of five discrete core skeletons embedded with privileged benzopyranyl substructure. The diversity of these core skeletons was expanded through the introduction of various substituents at the R, R1, and R2 positions from a single key intermediate in five different pathways. More importantly, we efficiently maximized the molecular diversity through the transformation of the core skeleton itself by using the library-to-library concept and created a distinctively different collection of small molecules with the same building blocks. A 434-member polyheterocyclic benzopyran library was constructed on a scale of about 10 mg with the potential for further diversification. Without further purification, the average purity of the library is 85%.

Validated liquid chromatography-tandem mass spectrometry method for determination of totally nine probe metabolites of cytochrome P450 enzymes and UDP-glucuronosyltransferases

A simplified, rapid, and selective liquid chromatography-tandem mass spectrometry method for the determination of the activities of cytochrome P450 (CYP) enzymes and UDP-glucuronosyltransferases (UGTs) in two separate settings was developed and successfully applied to 8 CYP isoenzymes and UGT2B7 enzyme activities in rat liver microsomes. The triple-quadrupole mass spectrometric detection was operated in positive mode for the probe metabolites: CYP1A2 (resorufin), CYP2B6 (hydroxybupropion), CYP2C19 (5-hydroxyomeprazole), CYP2D6 (dextrophan), CYP3A4 (6beta-hydroxytestosterone), and UGT2B7 (morphine-3-glucuronide); also in negative mode for CYP2C9 (4- hydroxytolbutamide), CYP2E1 (6-hydroxychloroxazone), and CYP4A (hydroxylauric acid). The metabolic reactions were terminated with acetonitrile, containing metoprolol and acetaminophen as the internal standard for positive and negative ion electrospray ionization, respectively. The method was validated over the concentration range of 25-2500 ng/mL for 5-hydroxyomeprazole, dextrophan, hydroxylauric acid, and morphine-3-glucuronide; 5-500 ng/mL for resorufin; 3-300 ng/mL for hydroxybupropion; 10-1000 ng/mL for 4-hydroxytolbutamide; 40-4000 ng/mL for 6-hydroxychloroxazone; and 63-6300 ng/mL for 6beta- hydroxytestosterone. All of the extraction recoveries of these analytes were greater than 85%, except for hydroxylauric acid at mid-concentration with a recovery of 83.2%¡À3.2%. The matrix effects were between 85.8% and 119.9%; the respective within- and between-run precisions were 0.9-12.0% and 2.0-13.9%; and the within- and between-run accuracy levels were 0.6-17.2% and 0.1-15.1%, respectively, for all these analytes. All of the analytes were stable during the assay and storage in the liver microsomes of Sprague-Dawley rats. The measurement activity of multiple enzymes was feasible using a cocktail approach. This method proved to be a robust, fast, accurate, specific and sensitive assay, and was successfully used to investigate in vivo enzyme activities of 8 major CYP isoenzymes and UGT2B7 in Sprague-Dawley rats with fatty livers. By the end of the eighth week, the CD-fed induced fatty liver rats showed a significant decrease in the activities of CYP1A2 and UGT2B7 as compared to the standard diet group.

In vitro inhibitory effects of friedelin on human liver cytochrome P450 enzymes

Context: Friedelin is a triterpenoid with several biological activities. However, the affects of Friedelin on the activity of human liver cytochrome P450 (CYP) enzymes remains unclear. Objective: This study investigates the inhibitory effects of Friedelin on the major human liver CYP isoforms (CYP3A4, 1A2, 2A6, 2E1, 2D6, 2C9, 2C19 and 2C8). Materials and methods: First, the inhibitory effects of Friedelin (100 lM) on the eight human liver CYP isoforms were investigated in vitro using human liver microsomes (HLMs), and then enzyme inhibition, kinetic studies, and time-dependent inhibition studies were conducted to investigate the IC50, Ki and Kinact/KI values of Friedelin. Results: The results indicate that Friedelin inhibited the activity of CYP3A4 and 2E1, with the IC50 values of 10.79 and 22.54 muM, respectively, but other CYP isoforms were not affected. Enzyme kinetic studies showed that Friedelin is not only a noncompetitive inhibitor of CYP3A4, but also a competitive inhibitor of CYP2E1, with Ki values of 6.16 and 18.02 muM, respectively. In addition, Friedelin is a time-dependent inhibitor of CYP3A4 with Kinact/Ki value of 4.84 nM/min. Discussion and conclusion: The in vitro studies of Friedelin with CYP isoforms suggested that Friedelin has the potential to cause pharmacokinetic drug interactions with other co-administered drugs metabolized by CYP3A4 and 2E1. Further clinical studies are needed to evaluate the significance of this interaction.

Drug Oxidation by Cytochrome P450BM3: Metabolite Synthesis and Discovering New P450 Reaction Types

There is intense interest in late-stage catalytic C-H bond functionalization as an integral part of synthesis. Effective catalysts must have a broad substrate range and tolerate diverse functional groups. Drug molecules provide a good test of these attributes of a catalyst. A library of P450BM3 mutants developed from four base mutants with high activity for hydrocarbon oxidation produced human metabolites of a panel of drugs that included neutral (chlorzoxazone, testosterone), cationic (amitriptyline, lidocaine) and anionic (diclofenac, naproxen) compounds. No single mutant was active for all the tested drugs but multiple variants in the library showed high activity with each compound. The high conversions enabled full product characterization that led to the discovery of the new P450 reaction type of oxidative decarboxylation of an alpha-hydroxy carboxylic acid and the formation a protected imine from an amine, offering a novel route to alpha-functionalization of amines. The substrate range and varied product profiles suggest that this library of enzymes is a good basis for developing late-stage C-H activation catalysts.
