Inhibition of aflatoxin B1 biosynthesis in Aspergillus flavus by anthocyanidins and related flavonoids

Anthocyanidins and precursors or related flavonoids were tested at concentrations from 0.3 to 9.7 mM (~0.1-3.0 mg/mL) for activity against growth and aflatoxin B1 biosynthesis by Aspergillus flavus Link:Fr. NRRL 3357. Aflatoxin B1 production was inhibited by all anthocyanidins tested, and 3-hydroxy compounds were more active than 3-deoxy forms. Monoglycosides of cyanidin were 40% less inhibitory than the aglycon, whereas a monoglucoside and a diglucoside of pelargonidin were 80 and 5%, respectively, as active as the aglycon. Of eight flavonoids tested, only kaempferol was moderately active, whereas luteolin and catechin were weakly inhibitory. Binary combinations of delphinidin and three other aflatoxin inhibitors acted independently of each other. Results with an aflatoxin pathway mutant indicated that anthocyanidin inhibition occurred before norsolorinic acid synthesis.

Simultaneous phenotyping of CYP2E1 and CYP3A using oral chlorzoxazone and midazolam microdoses

Aims: Chlorzoxazone is the paradigm marker substrate for CYP2E1 phenotyping in vivo. Because at the commonly used milligram doses (250?750 mg) chlorzoxazone acts as an inhibitor of the CYP3A4/5 marker substrate midazolam, previous attempts failed to combine both drugs in a common phenotyping cocktail. Microdosing chlorzoxazone could circumvent this problem. Method: We enrolled 12 healthy volunteers in a trial investigating the dose?exposure relationship of single ascending chlorzoxazone oral doses over a 10,000-fold range (0.05?500 mg) and assessed the effect of 0.1 and 500 mg of chlorzoxazone on oral midazolam pharmacokinetics (0.003 mg). Results: Chlorzoxazone area under the concentration?time curve was dose-linear in the dose range between 0.05 and 5 mg. A nonlinear increase occurred with doses ?50 mg, probably due to saturated presystemic metabolic elimination. While midazolam area under the concentration?time curve increased 2-fold when coadministered with 500 mg of chlorzoxazone, there was no pharmacokinetic interaction between chlorzoxazone and midazolam microdoses. Conclusion: The chlorzoxazone microdose did not interact with the CYP3A marker substrate midazolam, enabling the simultaneous administration in a phenotyping cocktail. This microdose assay is now ready to be further validated and tested as a phenotyping procedure assessing the impact of induction and inhibition of CYP2E1 on chlorzoxazone microdose pharmacokinetics.

A cocktail approach for assessing the in vitro activity of human cytochrome P450s: An overview of current methodologies

An assessment of cytochrome P450 (CYP) enzyme activity is essential for characterizing the phase I metabolism of biological systems or to evaluate the inhibition/induction properties of xenobiotics. CYPs have generally been investigated individually by single probes, and metabolite formation has been monitored by liquid chromatography-mass spectrometry (LC-MS). To increase the throughput, many probes have been applied to assess multiple CYP activities simultaneously within a single experiment. This strategy is called the cocktail approach, and it has already been reviewed for in vivo applications, but never for in vitro ones. This review focuses for the first time on an in vitro cocktail approach, and it references the most notable articles on this topic. The advantages and limitations of applying cocktails for the in vitro activity assessment of major human CYPs, namely, CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1 and subfamily CYP3A, are discussed. This article considers the probe reaction selections for each CYP according to regulatory recommendations, probe metabolic properties (. i.e., specificity and turnover), probe concentrations and analytical sensitivity, but it also highlights a challenge specific to cocktail design, which is probe-probe interaction. The last part of the review reports some methodologies for incubating these cocktails and discusses some important issues regarding the incubation time, enzyme concentrations and sample preparation.

Carbon?Nitrogen Bond Formation Through Cross-Dehydrogenative Coupling Reactions

There are many methods available in the synthetic toolbox to construct carbon?nitrogen bonds, but these standardly require preactivation of the substrate. These involve classical, nonmetal catalyzed methods (e.g., nucleophilic substitutions) and catalytic methods (e.g., the Ullmann condensation reaction) as well as modern metal-catalyzed approaches with wide scope (Buchwald?Hartwig reaction, hydrogen-borrowing reactions). Cross-dehydrogenative couplings (CDCs) couple a C?H with an N?H bond and do not require any preactivation and are therefore considered the ?nec plus ultra? in amination chemistry. Based on the ubiquitous nature of C?H bonds in substrates and the wide availability of amines as reactants they inherently show great application potential. Especially from a sustainable chemistry point of view it holds great promise, provided green oxidants can be used in a safe manner. However, though major advances have been made in the field, this last addition to the carbon?nitrogen bond forming toolbox is still in its infancy. The major investigations and advances dealing with CDCs for C?N bond formation since 2014 are summarized in this review. Intra- and intermolecular direct oxidative amination reactions on C(sp2)?H as well as C(sp3)?H bonds are included. Both metal-catalyzed and metal-free approaches are covered, as well as the corresponding mechanistic proposals.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
