Purpose: To develop a simple, rapid and sensitive ultra-performance liquid chromatography - electrospray ionization-mass spectrometry (UPLC–ESI–MS/MS) method was developed and fully validated for the simultaneous determination of galangin, kaempferide, galangin-3-methylether, kaempferol and quercetin in rat plasma after oral administration of Mongolian Medicine, Shudage-4 extracts. Methods: The galangin, kaempferide, galangin-3-methylether, kaempferol and quercetin were separated on a C18 column using 0.1 % formic acid at a flow rate of 0.4 mL / min and detected by a mass spectrometer in negative-ion mode with selected reaction monitoring (SRM) mode. Plasma samples were processed with a simple deproteinization technique using ethyl acetate and acetonitrile. Following the protein precipitation, the plasma samples were evaporated under gentle stream of nitrogen and analyzed by above method. Naringin was used as an internal standard (IS). Method validation was performed according to the Chinese Food and Drug Administration guidelines. Results: A good linearity (r2 ≥ 0.9990) was showed by the UPLC – ESI – MS / MS method, the low limits of quantification for galangin, kaempferide, galangin-3-methylether, kaempferol and quercetin were 229.8, 78.8, 32.0, 123.7 and 137.8 ng / mL, respectively. The results of inter-day and intra-day precisions met the experimental requirement (< 7.8 %). The matrix effect and recovery efficiency of the five analytes were more than 72.9 and 88.7 % respectively. The stability of the analytes were satisfactory. The UPLC – ESI – MS / MS method has been used for the five analytes’ pharmacokinetics study successfully after gastrointestinal route of the Mongolian Medicine Shudage-4. The pharmacokinetic parameters showed significant differences (P < 0.05) between the normal and gastric ulcer groups. The metabolism and transport of the five analytes in gastric ulcer rates were faster than in normal rats after administration of Shudage - 4 extract. Double-peak phenomenon appeared in galangin, galangin – 3 - methylether and quercetin. Conclusion: The results suggest that the metabolism and transport of Mongolian Medicine Shudage-4 in gastric ulcer rats is faster than in normal rats and may be enriched and acted on at the lesion site.

Veratrum nigrum L. is a well-known traditional Chinese medicine with a lot of pharmacological activities including antihypertensive, anticancer, and antifungal effects. In the current experiment, a rapid and sensitive UPLC-MS/MS method that takes only 7 min run time has been established and validated for simultaneous determination of eight bioactive compounds including cyclopamine, jervine, veratramine, polydatin, quercetin, apigenin, resveratrol, and veratrosine in rat plasma. The chromatographic separation of analytes and internal standard was performed on a Phenyl-Hexyl column ( 2.1 × 100   mm , 1.7 μm) with the mobile phase consisting of water (0.1% formic acid) and acetonitrile at a flow rate of 0.3 mL/min. An electrospray ionization (ESI) source was used to detect the samples in both positive and negative ion modes. The intra- and interday precisions of the compounds were less than 9.5% and the accuracy ranged from -10.8% to 10.4%. The extraction recoveries of the compounds were in the range of 85.1 ± 1.5 % to 102.6 ± 8.0 % , and the matrix effect ranged from 91.2 ± 4.5 % to 113.8 ± 1.5 % . According to the results of the stability test, the eight compounds have good stability under various conditions and the relative standard deviation (RSD) less than 13.2%. The pharmacokinetic parameters of the eight compounds in rat plasma after oral administration of Veratrum nigrum L. extract were successfully determined by the established UPLC-MS/MS method.

Aim and Objective:: An analytical method for the determination of mobocertinib, an investigational tyrosine kinase inhibitor, was developed and optimized by high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) in rat plasma. Materials and Methods:: Plasma samples were pretreated by the protein precipitation method with a methanol solution of osimertinib as the internal standard (IS). Chromatographic separation was performed using an Inertsil ODS-3 column (50 mm × 4.6 mm, I.D. 5 μm) column with the temperature maintained at 40 °C. The mobile phase consisted of water (containing 0.1% formic acid) and methanol in a gradient mode at a flow rate of 0.5 mL/min. Mass spectrometric detection was carried out in the selected reaction monitoring (SRM) mode with positive electrospray ionization, and the mass transitions of mobocertinib and osimertinib were m/z 587.01 → 71.88 and m/z 499.80 → 71.94, respectively. The method was validated in terms of selectivity, linearity, accuracy and precision, extraction recovery and matrix effect, stability and carryover as per the guidelines for bioanalytical method validation (FDA, 2018). The method was applied to the pharmacokinetic study of mobocertinib in rats by oral gavage at the doses of 2, 6, and 18 mg/kg. A total of 216 plasma samples from 18 rats were analyzed. Results:: It showed good linearity over the range of 1-1000 ng/mL (R2 = 0.9957). The intra-batch accuracy was within 94.65-102.59% and the precision was within 5.49-10.46%. The inter-batch accuracy was within 97.08-102.25% with a precision of 7.54-10.13%. The extraction recovery and matrix factor were acceptable for the bioanalysis of mobocertinib. Additionally, mobocertinib was found to be stable under the detected conditions. Mobocertinib showed linear pharmacokinetic characteristics following oral administration to rats at 2.0-18.0 mg/kg. Conclusion:: The developed and validated method was successfully employed in the pharmacokinetic study in rats following oral administration of mobocertinib at the doses of 2, 6, and 18 mg/kg.

Background: Curcumin (CUR), a natural isolated compound from turmeric, has been the promising star in fighting many diseases but the broad application of curcumin has been limited ascribed to low bioavailability. Objective: The aim of this study is to pursue the enhancement of curcumin bioavailability through co-administration of vitamin C. Methods: Such purpose was achieved through the analysis of curcumin pharmacokinetics by high performance liquid chromatography coupled with electrospray ionization - tandem mass spectrometry (HPLC - ESI - MS/MS). The plasma was separated on a C18 reverse phase column using acetonitrile and ammonium formate solution (pH 6.5; 2.0 mM) at 0.8 mL/min. MS/MS detection was carried out in negative mode using mass patterns of m/z 367.0 > 216.7 for curcumin and m/z 265.2 > 223.9 for internal standard (honokiol). Results: Successful application of the proposed method in the pharmacokinetic study presented clear changes in key pharmacokinetic parameters including the growth of AUC (0-t) up to 2.4 times, 2.2-fold increase of Cmax, 2.2-fold loss of CL, and 1.5-fold diminishment of t1/2. Conclusion: We developed an HPLC-ESI-MS/MS method for determination of curcumin in rat plasma and validated the improvement of bioavailability of curcumin through co-administration of vitamin C. We reasoned these changes to the inhibition of lipid peroxidation induced by the use of vitamin C. Such a simple strategy is possible to become an alternative for enhancing curcumin efficiency in practice.

Background: Quercitrin is widely found in herbal medicines, and it is particularly important in the design of new therapeutic agents. Because of its wide range of biological activities, methods for detecting quercitrin and its pharmacokinetics in biological samples must be investigated. Objective: To develop and validate a sensitive and reliable ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method for the quantitative determination of quercitrin levels in rat plasma and test its application in a pharmacokinetic investigation after the oral administration of Polygoni cuspidati folium capsules (HC). Methods: First, a rapid analytical method implementing UHPLC-MS/MS for the quantification of quercitrin levels in rat plasma was developed and validated. The analyte and internal standard (IS) tinidazole were extracted from rat plasma via protein precipitation with 800 μL of methanol and 50 μL of 1% formic acid solution. Chromatographic separation was performed using an Agilent ZORBAX C18 column within 4 min. Mass spectrometry was performed for quantification using a triple-quadrupole mass spectrometer employing electrospray ionization in the negative ion mode. The MRM transitions for quercitrin and IS were m/z 447.2→229.9 and m/z 246.0→125.8, respectively. The UHPLC-MS/MS method for the quantitative determination of quercitrin levels in rat plasma was then applied to investigate its pharmacokinetics after the oral administration of HC in rats. Results: The developed UHPLC-MS/MS method for detecting quercitrin in rat plasma was linear over the range of 0.1–160 ng/mL. The linear regression equation was Y = (0.7373 ± 0.0023)X − (0.0087 ± 0.0021) (r2 = 0.9978). The intra- and interday precision values were within 7.8%, and the recoveries of quercitrin and IS exceeding 67.3%. The UHPLC-MS/MS method was successfully applied to characterize the pharmacokinetic profile of quercitrin in eight rats after the oral administration of HC. The experimentally obtained values were fit to a one-compartment, first-order pharmacokinetic model, and they appeared to fit the concentration-time curve. Conclusion: Quercitrin was proven to be stable during sample storage, preparation, and analytical procedures. The pharmacokinetic parameters suggested that quercitrin may be present in the peripheral tissues of rats.

Background: Danyikangtai powder, a traditional Chinese medicine (TCM) formula, shows promise to become a novel drug candidate for the simultaneous treatment of chronic cholecystitis and chronic pancreatitis. However, the pharmacokinetic behavior of Danyikangtai powder remains unclear. Objective: We investigated the comparative pharmacokinetics of four flavonoids in rats after oral administration of Danyikangtai powder and three compatibilites. Materials and methods: The comparative pharmacokinetics was studied by ultra performance liquid chromatography tandem mass spectrometry (UPLC–MS/MS). Chromatographic separation was performed on an Universil XB-C18 column with a gradient mobile phase containing 0.1% (v/v) aqueous formic acid and acetonitrile. All analytes and internal standard were quantitated in the multiple reaction monitoring mode with a positive electrospray ionization interface. Results and discussion: Danyikangtai powder and Scutellariae radix have similar pharmacokinetic behaviors in rats after oral administration. However, the elimination of four flavonoids in rats after oral administration of Danyikangtai powder was accelerated, which was possibly related to the reduction of the potential hepatotoxicity of Scutellariae radix. The varying degrees of change in pharmacokinetic parameters after oral administration of different herb combinations suggested that herb–herb interactions occurred in vivo. Conclusions: This study will be helpful to reveal the safety, rational and mechanism of Danyikangtai powder formula compatibility, thereby providing pre-clinical research data for its new drug development and guidance for its rational clinical application.

AbstractA sensitive method for quantitation of JW5473 in rat plasma has been established using ultra performance liquid chromatography-electrospray ionization tandem mass spectrometry (UPLC-ESI/MS/MS). Tramadol was used as an internal standard. JW5473 and internal standard in plasma sample was extracted using acetonitrile (protein precipitation). A centrifuged upper layer was then evaporated and reconstituted with the mobile phase of 0.5% formic acid-acetonitrile (40:60, v/v). The reconstituted samples were injected into a C18 reversed-phase column. Using MS/MS in the multiple reaction monitoring (MRM) mode, JW5473 and tramadol were detected without severe interference from rat plasma matrix. JW5473 produced a protonated precursor ion ([M+H]+) at m/z 432.3 and a corresponding product ion at m/z 114.4. And the internal standard produced a protonated precursor ion ([M+H]+) at m/z 264.4 and a corresponding product ion at m/z 58.1. Detection of JW5473 in human plasma by the UPLC-ESI/MS/MS method was accurate and precise with a quantitation limit of 1.0 ng/mL. The validation, reproducibility, stability, and recovery of the method were evaluated. The method has been successfully applied to pharmacokinetic studies of JW5473 in rat plasma. Pharmacokinetic parameters of JW5473 was evaluated after intravenous (i. v.; at doses of 15 mg/kg) and oral (p.o.; at doses of 30 mg/kg) administration of JW5473 in rats. After p.o. administration (30 mg/kg) of JW5473, F (Fraction absorbed) value was approximately 70.5%.

Fructus polygoni orientalis (FPO) is widely used in clinical practice in China, especially in treatment of liver diseases including viral hepatitis, liver fibrosis, and liver cirrhosis. However, its pharmacokinetic (PK) alterations in liver fibrotic rats have rarely been reported. To study whether taxifolin, one of the main flavonoids in FPO can be absorbed into blood after oral administration of FPO extract and to compare the differences in pharmacokinetic parameters of taxifolin to normal and liver fibrotic rats induced by porcine serum (PS), a UPLC-MS/MS method was developed and validated for determination of taxifolin in rat plasma using puerarin as the internal standard (IS). All validation parameters met the acceptance criteria according to regulatory guidelines. The results indicated that after treatment of rats with PS alone for 12 weeks, the liver fibrotic model group was built successfully. The taxifolin can be absorbed into the blood after oral administration of the FPO extract. The Cmax of taxifolin was 1940 ± 502.2 ng/mL and 2648 ± 208.5 ng/mL (p<0.05), the AUC0∼t of taxifolin was 4949.7 ± 764.89 h·ng/mL and 6679.9 ± 734.26 h·ng/mL (p<0.05), the AUC0∼∞ of taxifolin was 5049.4 ± 760.7 and 7095.2 ± 962.3 h·ng/mL (p<0.05), and the mean residence time (MRT) of taxifolin was 2.46 ± 0.412 h and 3.17 ± 0.039 h (p<0.05) in the normal and fibrotic model groups, respectively. These results confirmed that the pharmacokinetic parameters of taxifolin are altered in liver fibrosis, manifested as Cmax, AUC0∼t, AUC0∼∞, and the mean residence time (MRT). It suggested that it is essential to consider the characteristics of pharmacokinetics after oral administration of FPO in liver disease patients.

Abstract1-(4-(Pyrrolidin-1-yl-methyl)phenyl)-3-(4-((3-(trifluoromethyl) phenyl)amino)quinazolin-6-yl)urea (ZCJ14), a novel epidermal growth factor receptor (EGFR) inhibitor, with diarylurea moiety, displays anticancer effect. In the present study, an LCMS/MS method was established to determine the concentration of ZCJ14 in rat plasma. Furthermore, the method was applied to investigate the pharmacokinetic characteristics of ZCJ14. Chromatographic separation of ZCJ14 and internal standard (IS) [1-phenyl-3-(4-((3-(trifluoromethyl)phenyl)amino) quinazolin-6-yl)urea] was accomplished by gradient elution using the Kromasil C18 column. The selected reaction monitoring transitions were performed at m/z 507.24→436.18 and 424.13→330.96 for ZCJ14 and IS, resp. The established method was linear over the concentration range of 10–1000 ng mL−1. The intra- and inter-day precisions were < 11.0 % (except for LLOQ which was up to 14.3 %) and the respective accuracies were within the range of 87.5–99.0 %. The extraction recovery and matrix effect were within the range of 88.4–104.5 % and 87.3–109.9 %, resp. ZCJ14 was stable under all storage conditions. The validated method was successfully applied to the pharmacokinetic study of ZCJ14 in rats, and the pharmacokinetic parameters have been determined. The oral bioavailability of ZCJ14 was found to be 46.1 %. Overall, this accurate and reliable quantification method might be useful for other diarylurea moiety-containing drugs.

AbstractIn this study, a simple and rapid liquid chromatography-mass spectrometry method was developed to simultaneously determinate five 16-deoxybarringtogenol C triterpenoid saponins with the potential of neuroprotection in rat plasma following the oral administration of the Xanthoceras sorbifolia Bunge husks extract. With digoxin as the internal standard, the plasma samples were pre-treated by ethyl acetate-isopropanol (1:1, v/v). The chromatographic separation of the five analytes was performed using a Phenomenex C18 column (250 mm × 4.6 mm, 5.0 mm) with a mobile phase of 0.05% formic acid (A)-acetonitrile (B). The mass spectrometric detection was carried out in the selected ion mode in positive ionization. The extraction recoveries of the five analytes were all over 71.28%. The established method was fully validated in line with the ICH and Food and Drug Administration (FDA) guidelines and successfully applied to the pharmacokinetic study on the five analytes in rat plasma. The terminal half-life (t1/2) of the five analytes was 2.92 ± 0.57, 5.52 ± 1.75, 2.48 ± 0.62, 2.95 ± 0.94, and 2.34 ± 0.81, respectively. This study was purposed to investigate the oral pharmacokinetic parameters and gain an in-depth insight into the reasonable preclinical use of the husks extract derived from X. sorbifolia Bunge.
