Development of a novel UHPLC-MS/MS method for the quantification of corynoxeine: Application to pharmacokinetics and tissue distribution studies in normal and chronic unpredictable mild stress-induced depression rats. J Pharm Biomed Anal 2024; 238:115850. [PMID: 37948778 DOI: 10.1016/j.jpba.2023.115850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 10/19/2023] [Accepted: 11/05/2023] [Indexed: 11/12/2023]
Abstract
Corynoxeine, a natural active alkaloid found in Genus Uncaria, has been reported to have anti-depressant effects. In this study, a sensitive and efficient ultra-high performance liquid chromatography tandem mass spectrometry method for quantifying corynoxeine in rat plasma and tissues was established, validated and applied to investigate the pharmacokinetics and tissue distribution differences between normal rats and chronic unpredictable mild stress (CUMS)-induced depression model rats following oral administration. All bio-samples were prepared by methanol protein precipitation method with theophylline as internal standard (IS). Chromatographic separation was conducted on an Agilent ZORBAX Eclipse Plus C18 column using mobile phase A (acetonitrile) and B (0.1% formic acid in water) in gradient elution mode with a flow rate of 0.3 mL/min. Mass spectrometric detection was performed in multiple-reaction monitoring mode with positive electrospray ionization source. The transitions of m/z 383.0→160.2 for corynoxeine and m/z 181.1→124.0 for IS were chosen for quantification. The method showed good linearity, stability, accuracy, precision, recovery, and non-significant matrix effect, which were within the acceptable ranges. The pharmacokinetic results revealed that the absorption and bioavailability of corynoxeine in depression rats decreased compared to normal rats. The tissue distribution of corynoxeine trended to be mostly in the intestine and stomach and the distribution of this compound in intestine tissue of depression rats was significantly increased compared to the normal rats. The pharmacokinetics and tissue distribution profiles of corynoxeine were altered in CUMS-induced depression rats compared to normal rats and these experimental findings could provide beneficial information to the mechanism research and clinical applications of corynoxeine.

Abstract
Hepatocellular carcinoma (HCC) causes 830000 deaths every year and is becoming the third malignant tumor worldwide. One of the primary reasons is the lack of effective drugs. Hernandezine (HER), a bisbenzylisoquinoline alkaloid of Thalictrum simplex, has been confirmed to have antitumor activity. But there are few reports about its effect on HCC and the underlying mechanisms still remain unclear. Therefore, the antitumor effects and mechanisms of HER on HCC were evaluated in HepG2 and Hep3B cells. The in vitro experiments demonstrated that HER significantly induced G0/G1 phase arrest, inhibited the proliferation and promoted cell apoptosis in liver cancer cell lines. In the mechanisms, the antitumor effects of HER on liver cancer cells were mediated by phosphatidylinositol 3-kinase (PI3K)-protein kinase B (AKT) pathway and reactive oxygen species (ROS), simultaneously. In one way, HER inhibited the activities of PI3K-AKT pathway, which interrupt the dimer formation of cyclin-dependent kinase 4 (CDK4) and cyclin D1 (CCND1) and result to G0/G1 phase arrest. In another way, after HER treatment, ROS accumulated in liver cancer cells and caused mitochondria injury which further influenced the expression of apoptosis-related proteins and eventually resulted to HepG2 and Hep3B cell apoptosis. In addition, HER showed a tumor restrain function in HepG2 and Hep3B bearing nude mice. Overall, these findings indicated that HER is a promising antitumor drug, which may provide a new direction for clinical HCC treatment.

Abstract
The need for reliable results in Toxicological Analysis is recognized and required worldwide. The analytical validation ensures that a method will provide trustworthy information about a particular sample when applied in accordance with a predefined protocol, being able to determine a specific analyte at a distinct concentration range for a well-defined purpose. The driving force for developing method validation for bioanalytical projects comes from the regulatory agencies. Thus, the approach of this work is to present theoretical and practical aspects of method validation based on the analysis objective, whether for prevention or diagnosis. Although various legislative bodies accept differing interpretations of requirements for validation, the process for applying validation criteria should be adaptable for each scientific intent or analytical purpose.

Abstract
Doxorubicin (DOX) is an effective anti-tumor drug widely used in clinics. Hernandezine (HER), isolated from a Chinese medicinal herb, has a selective inhibitory effect on DOX multidrug resistance, making DOX more effective in treating cancer. The aim of this study was to investigate the effect of the interaction of HER and DOX on pharmacokinetics. Male Sparague-Dawley rats were randomly divided into three groups: a single DOX group, a single HER group, and a combination group. Plasma concentrations of DOX and HER were determined by the LC-MS/MS method at specified time points after administration, and the main pharmacokinetic parameters were estimated. The results showed that there were significant differences in the Cmax and AUC0-∞ of DOX in the single drug group and combined drug group, indicating that HER could improve the absorption of DOX. However, DOX in combination, in turn, reduced the free drug concentration of HER, possibly because DOX enhanced the HER drug-protein binding effect. The results could be used as clinical guidance for DOX and HER to avoid adverse reactions.

Abstract
A rapid, sensitive and selective ultra high-performance liquid chromatography-tandem mass spectrometry UHPLC-MS/MS method has been developed and validated for the simultaneous determination of fourteen bioactive ingredients (gallic acid, geniposidic acid, protocatechuic acid, caffeic acid, ferulic acid, scopoletin, apigenin-7-o-glucuronide, daidzein, apigenin, ursolic acid, oleanolic acid, β-sitosterol, coniferin, and stigmasterol) in the plasma and tissues of rats. Danshensu and icariin were used as internal standards (IS1 and IS2). The chromatographic separation was achieved by using an Agilent ZORBAX RRHD Eclipse Plus C18 column (2.1 mm × 50 mm, 1.8 μm) with gradient elution using mobile phase, which consisted of 0.1% acetic acid water (solvent A) and methanol (solvent B) and pumped at a flow rate of 0.3 mL/min. Mass spectrometric detection was performed in multiple reaction monitoring (MRM) mode utilizing electrospray ionization (ESI) in positive and negative mode. The plasma samples were pretreated via protein precipitation with 300 μL of methanol containing 0.1% (v/v) formic acid and organ homogenates were processed by solid-phase extraction (SPE) with Waters Oasis HLB 3 cc (60 mg), respectively. The intra- and inter- day precisions (RSD%) were less than 10.3%, while the accuracy was ranged from -7.34% to 9.10%. Extraction recovery ranged from 85.02 to 112.0% and the matrix effects ranged from 85.12% to 109.6%. The present method exhibited excellent linearity and the lower limits of quantification (LLOQ) were 30.0 ng/mL, 15.0 ng/mL, 80.0 ng/mL, 30.0 ng/mL, 10.0 ng/mL, 3.0 ng/mL, 2.5 ng/mL, 2.5 ng/mL, 1.5 ng/mL, 15.0 ng/mL, 75.0 ng/mL, 15.0 ng/mL, 30.0 ng/mL, and 20.0 ng/mL for gallic acid, protocatechuic acid, geniposidic acid, caffeic acid, ferulic acid, scopoletin, apigenin-7-o-glucuronide, daidzein, apigenin, ursolic acid, oleanolic acid, β-sitosterol, coniferin, and stigmasterol, respectively. This analytical method was verified by the FDA guidelines for bioanalytical method validation and applied to investigate the pharmacokinetics and biodistribution of fourteen constituents of Hedyotis diffusa Willd extract in rats. These results provide useful information for improving the pharmacokinetics and biodistribution of fourteen bioactive ingredients of Hedyotis diffusa Willd extract in SD rats, supporting additional clinical application and Chinese herbal medicine safety evaluations.
