Effect of piperine on CYP2E1 enzyme activity of chlorzoxazone in healthy volunteers

1.?The purpose of the present study was to investigate the effect of piperine (PIP) on CYP2E1 enzyme activity and pharmacokinetics of chlorzoxazone (CHZ) in healthy volunteers. 2.?An open-label, two period, sequential study was conducted in 12 healthy volunteers. A single dose of PIP 20 mg was administered daily for 10 days during treatment phase. A single dose of CHZ 250 mg was administered during control and after treatment phases under fasting conditions. The blood samples were collected at predetermined time intervals after CHZ dosing and analyzed by HPLC. 3.?Treatment with PIP significantly enhanced maximum plasma concentration (Cmax) (3.14?4.96 mug/mL), area under the curve (AUC) (10.46?17.78 mug h/mL), half life (T1/2) (1.26?1.82 h) and significantly decreased elimination rate constant (Kel) (0.57?0.41 h ?1), apparent oral clearance (CL/F) (24.76?13.65 L/h) of CHZ when compared to control. In addition, treatment with PIP significantly decreased Cmax (0.22?0.15 mug/mL), AUC (0.94?0.68 mug h/mL), T1/2 (2.54?1.68 h) and significantly increased Kel (0.32?0.43 h ?1) of 6-hydroxychlorzoxazone (6-OHCHZ) as compared to control. Furthermore, treatment with PIP significantly decreased metabolite to parent (6-OHCHZ/CHZ) ratios of Cmax, AUC, T1/2 and significantly increased Kel ratio of 6-OHCHZ/CHZ, which indicate the decreased formation of CHZ to 6-OHCHZ. 4.?The results suggest that altered pharmacokinetics of CHZ might be attributed to PIP mediated inhibition of CYP2E1 enzyme, which indicate significant pharmacokinetic interaction present between PIP and CHZ. The inhibition of CYP2E1 by PIP may represent a novel therapeutic benefit for minimizing ethanol induced CYP2E1 enzyme activity and results in reduced hepatotoxicity of ethanol.

In vitro inhibitory effects of aurantio-obtusin on human liver cytochrome P450 enzymes

Aurantio-obtusin is an anthraquinone compound and possesses numerous pharmacological activities. However, whether aurantio-obtusin affects the activity of human liver cytochrome P450 (CYP) enzymes remains unclear. In this study, the inhibitory effects of aurantio-obtusin on the eight human liver CYP isoforms (i.e., 1A2, 3A4, 2A6, 2E1, 2D6, 2C9, 2C19, and 2C8) were investigated in vitro using human liver microsomes (HLMs). The results showed that aurantio-obtusin inhibited the activity of CYP1A2, 3A4, and 2E1, with IC50 values of 21.05, 13.57, and 16.12 muM, respectively, but that other CYP isoforms were not affected. Enzyme kinetic studies showed that aurantio-obtusin was not only a non-competitive inhibitor of CYP3A4, but also a competitive inhibitor of CYP1A2 and 2E1, with Ki values of 6.98, 9.52, and 8.32 muM, respectively. In addition, aurantio-obtusin is a time-dependent inhibitor for CYP3A4 with Kinact/KI value of 0.051/11.87 muM?1min?1. The in vitro studies of aurantio-obtusin with CYP isoforms indicate that aurantio-obtusin has the potential to cause pharmacokinetic drug interactions with other co-ad-ministered drugs metabolized by CYP1A2, 3A4, and 2E1. Further clinical studies are needed to evaluate the significance of this interaction.

Ultrasound assisted simultaneous reduction and direct functionalization of graphene oxide with thermal and cytotoxicity profile

The new sonochemical approach for simultaneous reduction and direct functionalization of graphene oxide (GrO) has been developed. The GrO was functionalized with 2-Aminobenzoxazole (2-ABOZ) in twenty min with complete deletion of hazardous steps. The significance of ultrasound was exemplified with the comparative conventional methods. The newly prepared f-(2-ABOZ)GrO was extensively characterized with near edge X-ray absorption fine structure (NEXAFS) spectroscopy, 13C solid state NMR, XPS, XRD, HRTEM, SAED, AFM, Raman, UV-vis, FTIR and TGA. The thermal stability of f-(2-ABOZ)GrO was confirmed with total percentage weight loss in TGA. The biological activity of f-(2-ABOZ)GrO was explored with MCF-7 and Vero cell lines. The inherent cytotoxicity was evaluated with SRB assay at 10, 20, 40 and 80 mug mL?1. The estimated cell viabilities were >78% with f-(2-ABOZ) GrO. A high cytocompatibility of f-(2-ABOZ)GrO was ensured with in vitro evaluation on living cell lines, and low toxicity of f-(2-ABOZ)GrO was confirmed its excellent biocompatibility. The morphological effect on Vero cell line evidently supports the formation of biocompatible f-(2-ABOZ)GrO. Therefore, f-(2-ABOZ)GrO was emerged as an advanced functional material for thermally stable biocompatible coatings.

Discovery of cytotoxic and pro-apoptotic compounds against leukemia cells: Tert-butyl-4-[(3-nitrophenoxy) methyl]-2,2-dimethyloxazolidine-3-carboxylate

Aims: We evaluated biological activity in leukemia cells lines of R and S enantiomers of tert-butyl 4-[(3-nitrophenoxy)-methyl]-2,2-dimethyloxazolidine-3- carboxylate (BNDC). Main methods: Cytotoxic activity was assessed by MTT assay. Flow cytometry assays were used to determined DNA fragmentation (Propidium Iodide-PI staining) and phosphatidylserine exposure (Annexin-V and PI staining). DNA condensation was evaluated by fluorescence microscopy using double-staining in leukemia cells (Hoechst and PI). Caspase activities were measured using Z-VAD-FMK, a non-selective caspase inhibitor, by flow cytometry and Z-DEVD-AMC, a selective caspase-3 substrate, by fluorescence spectrometry. Key findings: Both enantiomers displayed cytotoxic activity against leukemia cell lines (HL60, HL60.Bcl-2, HL60.Bcl-XL and Jurkat) with low toxicity against human peripheral blood mononuclear cell – PBMC based on IC50 values. In HL60 cell lines, compounds induce exposure of phosphatidylserine and DNA fragmentation, which could be blocked by pretreatment of cells with Z-VAD-FMK. Confirming this observation, both enantiomers induced caspase-3 activation. Additional analysis revealed an increased percentage of apoptotic cells (defined as those with fragmented nuclei and condensed chromatin) after treatment with compounds. Significance: Taken together, the results indicate that BNDC compounds exhibited cytotoxic and pro-apoptotic activities and have a potential for developing a new class of anticancer drugs.
