Rhinacanthin-C mediated herb-drug interactions with drugtransporters and phase i drug-metabolizing enzymes

Rhinacanthin-C is a major active constituent in Rhinacanthus nasutus (L.) Kurz, a plant widely used in herbal remedies. Its potential for pharmacokinetic herb-drug interaction may exist with drug transporters and drug metabolizing enzymes. This study assessed the possibility for rhinacanthin-C-mediated drug interaction by determining its inhibitory effects against major human efflux and influx drug transporters as well as various human cytochrome P450(CYP) isoforms. Rhinacanthin-C demonstrated a moderate permeability through the Caco-2 monolayers [Papp (AP-to-BL) 5 1.26 3 1026 cm/s]. It significantly inhibited transport mediated by both P-glycoprotein (P-gp) (IC50 5 5.20 mM) and breast cancer resistance protein (BCRP) (IC50 5 0.83 mM) across Caco-2 and BCRPoverexpressing Madin-Darby canine kidney II cells (MDCKII) cells. This compound also strongly inhibited uptake mediated by organic anion-transporting polypeptide 1B1 (OATP1B1) (IC50 5 0.70 mM) and OATP1B3 (IC50 5 3.95 mM) in OATP1B-overexpressing HEK cells. In addition to its inhibitory effect on these drug transporters, rhinacanthin-C significantly inhibited multiple human CYP isoforms including CYP2C8 (IC50 5 4.56 mM), 2C9 (IC50 5 1.52 mM), 2C19 (IC50 5 28.40 mM), and 3A4/5 (IC50 5 53 mM for midazolam and IC50 5 81.20 mM for testosterone), but not CYP1A2, 2A6, 2B6, 2D6, and 2E1. These results strongly support a high propensity for rhinacanthin-C as a perpetrator of clinical herb-drug interaction via inhibiting various influx and efflux drug transporters (i.e., P-gp, BCRP, OATP1B1, and OATP1B3) and CYP isoforms (i.e., CYP2C8, CYP2C9, and CYP2C19). Thus, the potential for significant pharmacokinetic herb-drug interaction should be addressed when herbal products containing rhinacanthin-C are to be used in conjunction with other prescription drugs.

Discovery of N -benzoxazol-5-yl-pyrazole-4-carboxamides as nanomolar SQR inhibitors

Succinate-ubiquinone oxidoreductase (SQR, EC 1.3.5.1, complex II), an essential component of cellular respiratory chain and tricarboxylic acid (or Krebs) cycle, has been identified as one of the most significant targets for pharmaceutical and agrochemical. Herein, with the aim of discovery of new antibacterial lead structure, a series of N-benzoxazol-5-yl-pyrazole-4-carboxamides were designed, synthesized, and evaluated for their SQR inhibitory effects. Very promisingly, one candidate (Ki Combining double low line 11 nM, porcine SQR) was successfully identified as the most potent synthetic SQR inhibitor so far. The further inhibitory kinetics studies revealed that the candidate is non-competitive with respect to the substrate cytochrome c and DCIP. Computational simulations revealed that the titled compounds have formed hydrogen bond with D-Y91 and B-W173 and the pyrazole ring formed cation- interaction with C-R46. In addition, in R1 position, -CHF2 group has increased the binding affinity and decreased the entropy contribution, while -CF3 group displayed completely opposite effect when bound with SQR. The results of the present work showed that N-benzoxazol-5-yl-pyrazole-4-carboxamide is a new scaffold for discovery of SQR inhibitors and worth further study.

A comprehensive assay for nine major cytochrome P450 enzymes activities with 16 probe reactions on human liver microsomes by a single LC/MS/MS run to support reliable in vitro inhibitory drug-drug interaction evaluation

1. A comprehensive method for the simultaneous characterization of xenobiotic compound inhibition of nine major CYP enzymes in human liver microsomes was established by using 16 CYP-catalyzed reactions of 14 probe substrates with three cocktail incubation sets and a single LC/MS/MS analysis.2. The three cocktail subgroups were developed to minimize the effects of organic solvents, polyunsaturated fatty acids and mutual substrate interactions: Group I was composed of tolbutamide (CYP2C9), S-mephenytoin (CYP2C19), testosterone (CYP3A4), dextromethorphan (CYP2D6); Group II was composed of nifedipine (CYP3A4), midazolam (CYP3A4), coumarin (CYP2A6), bupropion (CYP2B6), diclofenac (CYP2C9); Group III was composed of phenacetin (CYP1A2), chlorzoxazone (CYP2E1), omeprazole (CYP2C19 and CYP3A4), paclitaxel (CYP2C8), (+)-bufuralol (CYP2D6). In the case of CYP2C9, CYP2C19, CYP2D6 and CYP3A4, multiple probe substrates were used due to the phenomenon of multiple substrate-binding pockets and substrate-dependent inhibition. All probe metabolites were simultaneously analyzed with a polarity switching mode in a single LC/MS/MS run.3. This method was validated against the single probe substrate assay using 12 well-characterized CYP inhibitors and two new entities (GT0918, MDV3100). The IC50 values of each inhibitor in the cocktail agreed well with that of the individual probe drug as well as with values reported in previous literatures.

Evaluation of the impact of 16-dehydropregnenolone on the activity and expression of rat hepatic cytochrome P450 enzymes

16-dehydropregnenolone (DHP) is a promising novel antihyperlipidemic agent developed and patented by Central Drug Research Institute (CDRI), India. The purpose of the present study was to investigate whether DHP influences the activities and mRNA expression of hepatic drug-metabolizing cytochrome P450 (CYP) enzymes (CYP1A2, CYP2C11, CYP2D2, CYP2E1 and CYP3A1) in Sprague-Dawley (SD) rats. A cocktail suspension of CYP probe substrates which contained caffeine (CYP1A2), tolbutamide (CYP2C11), dextromethorphan (CYP2D2), chlorzoxazone (CYP2E1) and dapsone (CYP3A1) was administered orally on eighth- or fifteenth-day to rats pre-treated with DHP intragastrically at a dose of 36 and 72?mg/kg for one week and two weeks. The concentrations of probe drugs in plasma were estimated by liquid chromatography-tandem mass spectrometry (LC?MS/MS). Alongside, the effect of DHP on CYPs activity and mRNA expression levels were assayed in isolated rat liver microsomes and by real-time reverse transcription-polymerase chain reaction (RT-PCR), respectively. DHP had significant inducing effects on CYP1A2, 2C11, 2D2 and 2E1 with no effect on CYP3A1 in dose- and time-dependent manner, as revealed from the pharmacokinetic profiles of the probe drugs in rats. In-vitro microsomal activities and mRNA expression results were in good agreement with the in-vivo pharmacokinetic results. Collectively, the results unveiled that DHP is an inducer of rat hepatic CYP enzymes. Hence, intense attention should be paid when DHP is co-administered with drugs metabolized by CYP1A2, 2C11, 2D2 and 2E1, which might result in drug-drug interactions and therapeutic failure.
