Abstract
Riccardin D-N (RD-N) is an aminomethylated derivative of the macrocyclic bisbibenzyl compound riccardin D (RD), which has shown stronger activity against cancer cells than RD. However, there has been no research on the metabolism of RD-N. The present study aimed to characterize the in vitro metabolism and metabolic stability of RD-N after incubation with mouse and human hepatic S9 fractions using high performance liquid chromatography-hybrid triple quadrupole/linear ion trap mass spectrometry (HPLC-Q-LIT-MS). Multiple ion monitoring (MIM) and multiple reaction monitoring (MRM)-information dependent acquisition-enhanced product ion (MIM/MRM-IDA-EPI) scans were used to identify the metabolites formed. MRM scans were also used to quantify the changes in the amount of RD-N and to semi-quantify the main metabolites. Twenty-eight metabolic products were detected and 25 structures were predicted. Hydroxylation, dehydrogenation, glucuronidation, and methylation were proposed to be the principle metabolic pathways in the in vitro incubation with human and mouse hepatic S9 fractions. There were differences in the number and abundance of RD-N metabolites between the human and mouse hepatic S9 fractions. RD-N was shown to have good metabolic stability. After 2 h of incubation, 44% of the original RD-N remained in the human hepatic S9 fraction compared with 22% in the mouse. The major metabolites of RD-N, M4, M8, M20 and M21, were monitored semi-quantitatively using the typical transitions. Finally, HPLC-Q-LIT-MS was used for the identification and quantitation of the metabolites of R D-N, which is a simple and efficient method to rapidly screen potential drug candidates.

Simultaneous Quantitation of a Novel α₁/β₁-Blocker TJ0711 and Its Two Metabolites in Dog Plasma Using LC-MS/MS and Its Application to a Pharmacokinetic Study after Intravenous Infusion. Pharmaceutics 2019; 11:pharmaceutics11010038. [PMID: 30669292 PMCID: PMC6359546 DOI: 10.3390/pharmaceutics11010038] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Revised: 01/12/2019] [Accepted: 01/14/2019] [Indexed: 11/17/2022] Open
Abstract
TJ0711∙HCl, which is a novel α1/β1 adrenoceptor blocking agent with a ratio of 1:1 for α1/β1, is designed to treat and prevent perioperative hypertension. M1 and M3 were identified as important metabolites in vitro for either antihypertension activity or the major metabolite production. In order to obtain a pharmacokinetic profile of both TJ0711 and its metabolites, a rapid, selective, and reliable LC-MS/MS method was developed and validated for simultaneous determination of TJ0711 and two metabolites in beagle dog plasma via efficiently separating two interferential metabolites M16 and M4 from M1 and M3, respectively. Chromatographic separation was achieved on a Waters CORTECS C18+ column (2.1 × 100 mm, 2.7 μm). The mass spectrometric detection was carried out in positive ion MRM mode with ESI+ source. Protein precipitation was used in sample preparation and provided good recovery without a matrix effect. Good linearity was observed at the ranges of 0.5–100 ng/mL for TJ0711 and M3, 0.1–20 ng/mL for M1. Additional validation results were within the acceptance limits followed U.S. FDA guidelines for bioanalytical method validation. This method was successfully applied to an intravenous infusion pharmacokinetic study of TJ0711 at dosing rates of 3, 6, and 12 µg/kg/min in anesthetized beagle dogs for the first time. TJ0711 and its two metabolites exhibited effective proportionality in the dosage of 3 to 12 µg/kg/min. Neither TJ0711 nor its metabolites showed significant differences in pharmacokinetic parameters such as t1/2, CL, and Vss among three dose groups.

Abstract
A rapid, robust and sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for bioanalysis of TJ0711, a novel vasodilatory β-blocker in dog plasma. This assay is able to chromatographically separate TJ0711 from its isobaric metabolite as well as glucuronide conjugates. Chromatographic separation was achieved on a Welch Ultimate-XB C18 column (2.1 × 100 mm, 3 μm). The analyte and internal standard (propranolol) were extracted from plasma by liquid-liquid extraction using ethyl acetate. The mass spectrometric detection was carried out in positive ion multiple reaction monitoring mode. Good linearity was obtained over the concentration range of 0.5-500 ng/mL (r > 0.99) for TJ0711. Moreover, the method had good accuracy (RE ranging from -2.70 to -0.32%) and precision (RSD < 7.55%). TJ0711 was stable in dog plasma for at least 6 h at ambient temperature, for at least 30 days at -20°C and after three freeze-thaw cycles. This method was successfully applied to a preclinical pharmacokinetic study and the results demonstrated linear pharmacokinetics of TJ0711 over a dose range from 0.03 to 0.3 mg/kg. No significant gender differences were observed in TJ0711 plasma pharmacokinetic parameters.

Applicability of the Rayleigh equation for enantioselective metabolism of chiral xenobiotics by microsomes, hepatocytes and in-vivo retention in rabbit tissues. Sci Rep 2016; 6:23715. [PMID: 27021918 PMCID: PMC4810358 DOI: 10.1038/srep23715] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2015] [Accepted: 03/14/2016] [Indexed: 01/22/2023] Open
Abstract
In this study we propose a new approach for analyzing the enantioselective biodegradation of some antidepressant drugs mediated by human and rat liver microsomes by using the Rayleigh equation to describe the enantiomeric enrichment−conversion dependencies. Analysis of reported degradation data of additional six pesticides, an alpha blocker and a flame retardant by microsomes or hepatocytes in vitro reaffirmed the universality of the approach. In all the in vitro studied cases that involved enantioselective degradation, a Rayleigh dependence of the enantiomeric enrichment was observed. Published data regarding in vivo retention of myclobutanil in liver, kidney, muscle and brain tissues of rabbits following injection of the racemate were remodeled showing prevalence of the Rayleigh law for the chiral enrichment of the fungicide in the various tissues. This approach will revolutionize data organization in metabolic pathway research of target xenobiotics by either liver microsomes, hepatocytes or their organ-specific in vivo retention. The fact that the enantiomeric enrichment as a function of the conversion can be described by a single quantifier, will pave the road for the use of structure activity predictors of the enantiomeric enrichment and for mechanistic discrimination based on parametric dependence of the quantifier.

Abstract
The enantioselective pharmacokinetics of TJ0711 hydrochloride were studied in rats given different doses of rac-TJ0711 hydrochloride via intravenous and oral routes. R- and S-TJ0711 hydrochloride were both rapidly absorbed, and the average AUC0-∞ of R-TJ0711 hydrochloride was greater than that of S-TJ0711 hydrochloride after intragastric administration, with an R/S AUC ratio 1.11 and 1.35 for 30 and 50 mg/kg dose group, respectively. In contrast, the average AUC0-∞ of R-TJ0711 hydrochloride was smaller than that of S-TJ0711 hydrochloride after intravenous injection, with an R/S AUC ratio 0.57 and 0.73 for 10 and 20 mg/kg dose group, respectively. R-TJ0711 hydrochloride plasma half-lives were shorter than those of S-TJ0711 hydrochloride for all groups. AUC0-4h and Cmax between the two enantiomers were significantly different after oral administration of 50 mg/kg dose of the racemate, while no significant differences between the two enantiomers were found for all the pharmacokinetic parameters of the 30 mg/kg dose group. Significant differences between the two enantiomers were detected for nearly all the pharmacokinetic parameters after intravenous administration, except for the VZ of 20 mg/kg dose group. This study suggests that dose and route of administration will influence the enantioselectivity in the pharmacokinetics of TJ0711 hydrochloride in rats.

Abstract
13-197 is a novel NF-κB inhibitor that shows promising in vitro efficacy data against pancreatic cancer. In this study, we characterized the pharmacokinetics, tissue distribution, protein binding and metabolism of 13-197 in mice and rats. A valid, sensitive and selective LC-MS/MS method was developed. This method was validated for the quantification of 13-197, in the range of 0.1 or 0.2-500 ng/mL in mouse plasma, liver, kidney, lung, heart, spleen, brain, urine and feces. 13-197 has low bioavailability of 3 and 16% in mice and rats, respectively. It has faster absorption in mice with 12-fold shorter Tmax than in rats. Tissue concentrations were 1.3-69.2-fold higher in mice than in rats at 72 h after intravenous administration. 13-197 is well distributed to the peripheral tissues and has relatively high tissue-plasma concentration ratios, ranging from 1.8 to 3634, in both mice and rats. It also demonstrated more than 99% binding to plasma proteins in both mice and rats. Finally, <1% of 13-197 is excreted unchanged in urine and feces, and metabolite profiling studies detected more than 20 metabolites in mouse and rat plasma, urine and feces, which indicates that 13-197 is extensively metabolized and primarily eliminated by metabolism rather than by excretion.
