An extensive cocktail approach for rapid risk assessment of in vitro CYP450 direct reversible inhibition by xenobiotic exposure

Acute exposure to environmental factors strongly affects the metabolic activity of cytochrome P450 (P450). As a consequence, the risk of interaction could be increased, modifying the clinical outcomes of a medication. Because toxic agents cannot be administered to humans for ethical reasons, in vitro approaches are therefore essential to evaluate their impact on P450 activities.In this work, an extensive cocktail mixture was developed and validated for in vitro P450 inhibition studies using human liver microsomes (HLM). The cocktail comprised eleven P450-specific probe substrates to simultaneously assess the activities of the following isoforms: 1A2, 2A6, 2B6, 2C8, 2C9, 2C19, 2D6, 2E1, 2J2 and subfamily 3A. The high selectivity and sensitivity of the developed UHPLC-MS/MS method were critical for the success of this methodology, whose main advantages are: (i) the use of eleven probe substrates with minimized interactions, (ii) a low HLM concentration, (iii) fast incubation (5 min) and (iv) the use of metabolic ratios as microsomal P450 activities markers. This cocktail approach was successfully validated by comparing the obtained IC50 values for model inhibitors with those generated with the conventional single probe methods. Accordingly, reliable inhibition values could be generated 10-fold faster using a 10-fold smaller amount of HLM compared to individual assays. This approach was applied to assess the P450 inhibition potential of widespread insecticides, namely, chlorpyrifos, fenitrothion, methylparathion and profenofos. In all cases, P450 2B6 was the most affected with IC50 values in the nanomolar range. For the first time, mixtures of these four insecticides incubated at low concentrations showed a cumulative inhibitory in vitro effect on P450 2B6.

Binuclear molybdenum alkoxide as the versatile catalyst for the conversion of carbon dioxide

The triply bonded dimolybdenum compound, Mo2(OtBu)6 (1), was investigated as a homogeneous catalyst for the conversion of CO2. The compound 1 acted as a rare example of a versatile catalyst with an impressive ability to transform CO2 into various valuable products, including propiolic acids, cyclic carbonates, and benzo[d]thiazole- and benzo[d]oxazolecarboxylic acids, in high yields with short reaction times and excellent selectivity at ambient pressure and low temperatures (25-75 C). This is the first report of the application of a metal-metal bond-containing species in the catalytic conversion of CO2.

The Effects of Cruciferous Vegetable-Enriched Diets on Drug Metabolism: A Systematic Review and Meta-Analysis of Dietary Intervention Trials in Humans

Relatively few studies exist in the literature that discuss the effects of diet on drug metabolism and how this can affect interindividual differences in systemic drug exposure. Several studies have investigated the effects of cruciferous vegetables (Cruciferae) or their constituents on drug-metabolizing activity, as these vegetables form an important part of many peoples? diets. In general, the ingestion of cruciferous vegetables is associated with induction of cytochrome P450 (CYP) 1A2 activity in vivo; however, there is contention between reports, and the clinical significance of potential diet?drug interactions remains unclear. This study reports a systematic review, critical appraisal, and meta-analysis of the published literature in this area, and discusses the clinical significance of Cruciferae-enriched diets in the context of diet?drug interactions. Twenty-three dietary intervention trials with drug metabolism end points were identified across Embase, Medline, and the Cochrane Controlled Register of Trials (CENTRAL). Cruciferous vegetables represented in the literature included broccoli, Brussels sprout, cabbage, cauliflower, radish, and watercress. A range of phase I and II drug-metabolizing enzymes and phenotyping metrics were represented in the literature. The meta-analyses performed demonstrated a significant effect on CYP1A2 and glutathione S-transferase-alpha (GST-alpha), with consumption of Cruciferae increasing the activities of these enzymes by 20?40% and 15?35%, respectively. The results herein suggest that patients undergoing pharmacotherapy with CYP1A2 or GST-alpha substrates could have altered drug exposure profiles if they regularly eat large or variable amounts of cruciferous vegetables. Recommendations regarding the design of future randomized, controlled trials to test hypotheses in this area are included.

Metabolic characterization of meso-dihydroguaiaretic acid in liver microsomes and in mice

meso-Dihydroguaiaretic acid (MDGA) is a major component of Myristica fragrans and Machilus thunbergii that is traditionally used as a spice and for medicinal purposes. Despite reports of various biological activities exerted by MDGA, there is no information regarding its metabolic properties. The purpose of this study was to determine the metabolic stability and cytochrome P450 (CYP) inhibitory potential of MDGA, using pooled human liver microsomes (HLMs) to characterize its metabolic properties. In addition, pharmacokinetic analysis was performed in mice treated intravenously (5 mg/kg) or orally (20 mg/kg) with MDGA for comparison with our in vitro results. The half-life of MDGA in HLMs and mouse liver microsomes incubated with NADPH, UDPGA or NADPH plus UDPGA was 25.41 and 22.74, 0.39 and 0.20 or 0.28 and 0.22 min, respectively. In our pharmacokinetic study, MDGA rapidly declined in plasma and had low bioavailability, which was attributable to extensive metabolism by UDP-glucuronosyltransferases and CYPs. Among CYP isoforms, CYP2E1 activity was selectively inhibited by MDGA through a competitive inhibitory mode, with an inhibitory constant (Ki) value of 13.1 muM. These results suggest that MDGA can be used as a selective CYP2E1 inhibitor in vitro, which warrants evaluation of the pharmacological significance of MDGA-induced CYP2E1 inhibition.

Dithiocarboxylic Acids, Dithiocarboxylic Esters, or Thiocarboxylic Amides by Reaction of Methylene-active Chloromethyl Compounds with Sulfur

With a mixture of sulfur and amine in DMF at room temperature halomethyl compounds (1,5-10) can be oxidized to give thiocarboxylic acids (2,11-16) and their derivatives (3,4,17-35).We studied this reaction in detail especially with chloroacetic derivatives (11-15) or chloromethyl heterocycles (16) formally derived from chloroacetic acid.The resulting thiooxalic acid derivatives (11-27) represent activated acids and very useful C2-synthons, especially for the synthesis of heterocycles.Oxidation in the presence of triethylamine leads to dithiocarboxylates (11-16) which can be alkylated to dithioesters (17-27) in high yields.As a rule, with different primary and secondary amines instead of tertiary amines these dithiocarboxylates or dithiocarboxylic esters can be transformed already at low temperatures to thioamides (28-35).
