Evaluation of the inhibition potential of plumbagin against cytochrome P450 using LC-MS/MS and cocktail approach

Plumbagin (5-hydroxy-2-methyl-1,4-naphthoquinone), a natural naphthoquinone compound isolated from roots of Plumbago zeylanica L., has drawn a lot of attention for its plenty of pharmacological properties including antidiabetes and anti-cancer. The aim of this study was to investigate the effects of plumbagin on CYP1A2, CYP2B1/6, CYP2C9/11, CYP2D1/6, CYP2E1 and CYP3A2/4 activities in human and rat liver and evaluate the potential herb-drug interactions using the cocktail approach. All CYP substrates and their metabolites were analyzed using high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). Plumbagin presented non-time-dependent inhibition of CYP activities in both human and rat liver. In humans, plumbagin was not only a mixed inhibitor of CYP2B6, CYP2C9, CYP2D6, CYP2E1 and CYP3A4, but also a non-competitive inhibitor of CYP1A2, with Ki values no more than 2.16 muM. In rats, the mixed inhibition of CYP1A2 and CYP2D1, and competitive inhibition for CYP2B1, CYP2C11 and CYP2E1 with Ki values less than 9.93 muM were observed. In general, the relatively low Ki values of plumbagin in humans would have a high potential to cause the toxicity and drug interactions involving CYP enzymes.

Lack of correlation between in vitro and in vivo studies on the inhibitory effects of (-)-sophoranone on CYP2C9 is attributable to low oral absorption and extensive plasma protein binding of (-)-sophoranone

(-)-Sophoranone (SPN) is a bioactive component of Sophora tonkinensis with various pharmacological activities. This study aims to evaluate its in vitro and in vivo inhibitory potential against the nine major CYP enzymes. Of the nine tested CYPs, it exerted the strongest inhibitory effect on CYP2C9-mediated tolbutamide 4-hydroxylation with the lowest IC50 (Ki) value of 0.966 ¡À 0.149 muM (0.503 ¡À 0.0383 muM), in a competitive manner. Additionally, it strongly inhibited other CYP2C9-catalyzed diclofenac 4′-hydroxylation and losartan oxidation activities. Upon 30 min preincubation of human liver microsomes with SPN in the presence of NADPH, no obvious shift in IC50 was observed, suggesting that SPN is not a time-dependent inactivator of the nine CYPs. However, oral co-administration of SPN had no significant effect on the pharmacokinetics of diclofenac and 4′-hydroxydiclofenac in rats. Overall, SPN is a potent inhibitor of CYP2C9 in vitro but not in vivo. The very low permeability of SPN in Caco-2 cells (Papp value of 0.115 ¡Á 10-6 cm/s), which suggests poor absorption in vivo, and its high degree of plasma protein binding (>99.9%) may lead to the lack of in vitro-in vivo correlation. These findings will be helpful for the safe and effective clinical use of SPN.

Photocatalytic pilot scale degradation study of pyrimethanil and of its main degradation products in waters by means of solid-phase extraction followed by gas and liquid chromatography with mass spectrometry detection

Aqueous solutions of Pyrimethanil, as technical grade product (TP), with 98.2% purity, and commercial formulation (CF), containing 40% (w/v) of Pyrimethanil, were submitted to photocatalytic degradation under sunlight in the presence of TiO2 as catalyst in a preindustrial pilot plant. Complete Pyrimethanil degradation was achieved after ca. 230 min of irradiation, in both TP and CF, but total mineralization was not observed, as was demonstrated by the TOC values of 3-4 mg/L, measured at the end of the experiments (907 min). A qualitative and quantitative study of the degradation products (DPs) generated during the process was performed by GC- MS, using El and Cl as ionization modes, and by LC-API-MS, using Atmospheric Pressure Chemical Ionization (APCI) and Electrospray (ES) interfacing techniques. Up to 22 compounds could be detected as degradation intermediates. To evaluate the extraction efficiency of these DPs from the aqueous solution, specially for the more polar intermediates, a recovery study was performed with Pyrimethanil and seven of the commercially available DPs. Liquid-liquid extraction (LLE) and solid-phase extraction (SPE), with different sorbents, were compared. A SPE method using Lichrolut-EN cartridges was selected as the most adequate, but recoveries ?60% were obtained for four of the DPs studied (aniline formamide, 1,3-benzenediol, and 4,6- dimethyl-2-pyrimidinamine). Structure identification of DPs allowed us to propose two main routes in the degradation process. One route involves the attack of hydroxyl radicals to the pyrimidine and benzene rings with further rings opening and the other one corresponds to a photoinduced hydrolysis of the molecule by the amine group bonds.

Sulfenylation of beta-Diketones Using C- H Functionalization Strategy

Sulfenylation of beta-diketones is challenging as beta-diketones undergo deacylation after sulfenylation in the reaction medium. The sulfenylation of beta-diketones without deacylation under metal-free conditions at ambient temperature via a cross dehydrogenative coupling (CDC) strategy is reported. The resultant products can be further manipulated to form alpha,alpha-disubstituted beta-diketones and pyrazoles.
