Available and novel plant-based carbon dots derived from Vaccaria Semen carbonisata alleviates liver fibrosis. Front Mol Biosci 2023; 10:1282929. [PMID: 38116381 PMCID: PMC10729316 DOI: 10.3389/fmolb.2023.1282929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 10/27/2023] [Indexed: 12/21/2023] Open
Abstract
Background: Liver fibrosis represents an intermediate stage in the progression of liver disease, and as of now, there exists no established clinical therapy for effective antifibrotic treatment. Purpose: Our aim is to explore the impact of Carbon dots derived from Vaccaria Semen Carbonisata (VSC-CDs) on carbon tetrachloride-induced liver fibrosis in mice. Methods: VSC-CDs were synthesized employing a modified pyrolysis process. Comprehensive characterization was performed utilizing various techniques, including transmission electron microscopy (TEM), multiple spectroscopies, X-ray photoelectron spectroscopy (XPS), and high-performance liquid chromatography (HPLC). A hepatic fibrosis model induced by carbon tetrachloride was utilized to evaluate the anti-hepatic fibrosis effects of VSC-CDs. Results: VSC-CDs, exhibiting a quantum yield (QY) of approximately 2.08%, were nearly spherical with diameters ranging from 1.0 to 5.5 nm. The VSC-CDs prepared in this study featured a negative charge and abundant chemical functional groups. Furthermore, these particles demonstrated outstanding dispersibility in the aqueous phase and high biocompatibility. Moreover, VSC-CDs not only enhanced liver function and alleviated liver damage in pathomorphology but also mitigated the extent of liver fibrosis. Additionally, this study marks the inaugural demonstration of the pronounced activity of VSC-CDs in inhibiting inflammatory reactions, reducing oxidative damage, and modulating the TGF-β/Smad signaling pathway. Conclusion: VSC-CDs exerted significant potential for application in nanodrugs aimed at treating liver fibrosis.

Ahn CR, Baek SH. Enhancing Gastric Cancer Therapeutic Efficacy through Synergistic Cotreatment of Linderae Radix and Hyperthermia in AGS Cells. Biomedicines 2023; 11:2710. [PMID: 37893084 PMCID: PMC10604735 DOI: 10.3390/biomedicines11102710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 09/21/2023] [Accepted: 09/26/2023] [Indexed: 10/29/2023] Open
Abstract
Gastric cancer remains a global health threat, particularly in Asian countries. Current treatment methods include surgery, chemotherapy, and radiation therapy. However, they all have limitations, such as adverse side effects, tumor resistance, and patient tolerance. Hyperthermia therapy uses heat to selectively target and destroy cancer cells, but it has limited efficacy when used alone. Linderae Radix (LR), a natural compound with thermogenic effects, has the potential to enhance the therapeutic efficacy of hyperthermia treatment. In this study, we investigated the synergistic anticancer effects of cotreatment with LR and 43 °C hyperthermia in AGS gastric cancer cells. The cotreatment inhibited AGS cell proliferation, induced apoptosis, caused cell cycle arrest, suppressed heat-induced heat shock responses, increased reactive oxygen species (ROS) generation, and promoted mitogen-activated protein kinase phosphorylation. N-acetylcysteine pretreatment abolished the apoptotic effect of LR and hyperthermia cotreatment, indicating the crucial role of ROS in mediating the observed anticancer effects. These findings highlight the potential of LR as an adjuvant to hyperthermia therapy for gastric cancer. Further research is needed to validate these findings in vivo, explore the underlying molecular pathways, and optimize treatment protocols for the development of novel and effective therapeutic strategies for patients with gastric cancer.

Abstract
CONTEXT Laurolitsine is an aporphine alkaloid and exhibits potent antihyperglycemic and antihyperlipidemic effects in ob/ob mice. OBJECTIVE To investigate the pharmacokinetics, tissue distribution and excretion of laurolitsine. MATERIALS AND METHODS A LC-MS/MS method was established and validated to determine laurolitsine concentrations in the biological matrix of rats (plasma, tissue homogenate, urine and faeces). 10 Sprague-Dawley (SD) rats were used for plasma exposure study: 5 rats were injected with 2.0 mg/kg of laurolitsine via the tail vein, and the other 5 rats were administered laurolitsine (10.0 mg/kg) by gavage. 25 SD rats used for tissue distribution study and 5 SD rats for urine and faeces excretion study: rats administered laurolitsine (10.0 mg/kg) by gavage. After administered, serial blood, tissue, urine and faeces were collected. Analytical quantification was performed by a previous LC-MS/MS method. The pharmacokinetics, bioavailability, tissue distribution and excretion of laurolitsine were described. RESULTS The pharmacokinetic parameters of oral and intravenous administration with Tmax were 0.47 and 0.083 h, t1/2 were 3.73 and 1.67 h, respectively. Oral bioavailability was as low as 18.17%. Laurolitsine was found at a high concentration in the gastrointestinal tract, liver, lungs and kidneys (26 015.33, 905.12, 442.32 and 214.99 ng/g at 0.5 h, respectively) and low excretion to parent laurolitsine in urine and faeces (0.03 and 1.20% in 36 h, respectively). CONCLUSIONS This study established a simple, rapid and accurate LC-MS/MS method to determine laurolitsine in different rat samples and successful application in a pharmacokinetic study.

Baihe Wuyao decoction ameliorates CCl 4-induced chronic liver injury and liver fibrosis in mice through blocking TGF-β1/Smad2/3 signaling, anti-inflammation and anti-oxidation effects. JOURNAL OF ETHNOPHARMACOLOGY 2020; 263:113227. [PMID: 32783983 DOI: 10.1016/j.jep.2020.113227] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Revised: 05/31/2020] [Accepted: 07/02/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Baihe Wuyao decoction (BWD), a prescription of Traditional Chinese Medicines, composed of Lilium brownii var. viridulum Baker.(Lilii Bulbus) and Lindera aggregata (Sims) Kosterm. (Linderae Radix), has been used to treat epigastric pain and superficial gastritis for hundreds of years in China. Recently, some compounds obtained from Lilii Bulbus and Linderae Radix had active effects of hepatic protection or liver fibrosis alleviation. Thus, we aim to evaluate the effects of BWD on treatment of chronic liver injury and liver fibrosis induced by carbon tetrachloride (CCl4) and to elucidate the possible molecular mechanism. MATERIALS AND METHODS Mice were treated with BWD (low, medium and high dose), diammonium glycyrrhizinate or vehicle by oral gavage once daily, simultaneously intraperitoneal injected with a single dose of CCl4 (1 μl/g body weight) twice a week for consecutive 6 weeks. Next, all mice were sacrificed after fasted 12 h, and serums and liver tissues were harvested for analysis. The hepatic injury was detected by serum biomarker assay, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT). The hepatic histology and collagen were illustrated by hematoxylin-eosin staining and Sirius red staining respectively. The antioxidant capacity of liver tissues was evaluated by the contents of superoxide dismutase (SOD) and malondialdehyde (MDA) in liver homogenization. The mRNA gene or protein expressions related to fibrosis, oxidative stress and inflammation molecules were performed by real-time quantitative PCR (RT-PCR) or Western-blot. RESULTS BWD exhibited a good hepatic protection with ameliorating liver histological changes, decreasing serum AST and ALT contents, and reducing hepatic fibrosis with stimulation ECMs (such as Collagen1 and Collagen3) degradation. BWD inhibited hepatic stellate cells (HSCs) activation, promoted matrix metalloproteinase-2 (MMP2), MMP9, and MMP12 while suppressing tissue inhibitors of matrix metalloproteinase-1 (TIMP1) expression, and blocked traditional fibrosis TGF-β1/Smad2/3 signal pathway. Moreover, BWD exhibited anti-inflammation effect proved by the reduction of liver Interleukin-1β (IL-1β), TNF-α, IL-11 mRNA levels and promoted anti-oxidation effects determined by inhibition of liver MDA and iNOS levels while promoting liver SOD and Mn-SOD. CONCLUSION BWD ameliorates CCl4-induced CLI and liver fibrosis which is correlated to its blocking TGF-β1/Smad2/3 signaling, anti-inflammation, and anti-oxidation effects. BWD, as a small traditional prescription, is a promising treatment for CLI and liver fibrosis through multiple pharmacological targets.

Abstract
ABSTRACT Stephania tetrandra S. Moore (S. tetrandra) is distributed widely in tropical and subtropical regions of Asia and Africa. The root of this plant is known in Chinese as "Fen Fang Ji". It is commonly used in traditional Chinese medicine to treat arthralgia caused by rheumatism, wet beriberi, dysuria, eczema and inflamed sores. Although promising reports have been published on the various chemical constituents and activities of S. tetrandra, no review comprehensively summarizes its traditional uses, phytochemistry, pharmacology and toxicology. Therefore, the review aims to provide a critical and comprehensive evaluation of the traditional use, phytochemistry, pharmacological properties, pharmacokinetics and toxicology of S. tetrandra in China, and meaningful guidelines for future investigations.

Abstract
Boldo leaves (Boldo folium, from Peumus boldus Mol.) are very frequently used as a medicinal herb in Chile and are exported to many countries to be used in teas or as extracts included in herbal remedies, primarily as an aid to digestion and as a mild sedative. Scientific support for these uses is scanty, and boldine, an alkaloid viewed as characteristic of the tree and present in high concentration in the bark, is extracted by specialized companies and sold as the supposed main active constituent. Consequently, boldine has been the subject of a considerable number of research papers, while some of the other alkaloids present to a greater extent in the leaves have been relatively neglected except when found in large amounts in other species. These studies range from assays of antioxidant activity to anti-inflammatory, antineoplastic and other medical applications. The essential oil, usually containing a large percentage of the toxic ascaridole, was once used as a vermifuge and is now regarded with caution, but is still of interest as a possible natural insecticide, fungicide, antiparasitic and herbicide. The last decade has seen an explosive increase in papers pointing to possible uses of boldo and its constituents. This review attempts to bring these publications together in a comprehensive way with the purpose of stimulating and orienting further research into the useful properties of this Chilean endemic tree.

[DOI: 10.2174/1573411014666180423152612] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/20/2022]
Abstract
Introduction:
Ultra-Performance Liquid Chromatographic (UPLC) method enables analyst
to establish an analysis at higher pressure than High Performance Liquid Chromatographic (HPLC)
method towards liquid chromatographic methods. UPLC method provides the opportunity to study a
higher pressure compared to HPLC, and therefore smaller column in terms of particle size and internal
diameter are generally used in drug analysis. The UPLC method has attracted gradually due to its advantages
such as short analysis time, the small amount of waste reagents and the significant savings in
the cost of their destruction process. In this review, the recent selected studies related to the UPLC
method and its method validation are summarized. The drug analyses and the results of the studies
which were investigated by UPLC method, with certain parameters from literature are presented.
Background:
Quantitative determination of drug active substances by High-Performance Liquid
Chromatography (HPLC) from Liquid Chromatography (LC) methods has been carried out since the
1970's with the use of standard analytical LC methods. In today's conditions, rapid and very fast even
ultra-fast, flow rates are achieved compared to conventional HPLC due to shortening analysis times,
increasing method efficiency and resolution, reducing sample volume (and hence injection volume),
reducing waste mobile phase. Using smaller particles, the speed and peak capacity are expanding to
new limit and this technology is named as Ultra Performance Liquid Chromatography. In recent years,
as a general trend in liquid chromatography, ultra-performance liquid chromatography has taken the
place of HPLC methods. The time of analysis was for several minutes, now with a total analysis time
of around 1-2 minutes. The benefits of transferring HPLC to UPLC are much better understood when
considering the thousands of analyzes performed for each active substance, in order to reduce the cost
of analytical laboratories where relevant analysis of drug active substances are performed without
lowering the cost of research and development activities.
Methods:
The German Chemist Friedrich Ferdinand Runge, proposed the use of reactive impregnated
filter paper for the identification of dyestuffs in 1855 and at that time the first chromatographic method
in which a liquid mobile phase was used, was reviewed. Christian Friedrich Chönbein, who reported
that the substances were dragged at different speeds in the filter paper due to capillary effect, was
followed by the Russian botanist Mikhail S. Tswet, who planted studies on color pigment in 1906.
Tswet observes the color separations of many plant pigments, such as chlorophyll and xanthophyll
when he passes the plant pigment extract isolated from plant through the powder CaCO3 that he filled
in the glass column. This method based on color separation gives the name of "chromatographie"
chromatography by using the words "chroma" meaning "Latin" and "graphein" meaning writing.
Results and Conclusion:
Because the UPLC method can be run smoothly at higher pressures than the
HPLC method, it offers the possibility of analyzing using much smaller column sizes and column diameters.
Moreover, UPLC method has advantages, such as short analysis time, the small amount of
waste reagents and the significant savings in the cost of their destruction process. The use of the
UPLC method especially analyses in biological samples such as human plasma, brain sample, rat
plasma, etc. increasingly time-consuming due to the fact that the analysis time is very short compared
to the HPLC, because of the small amount of waste analytes and the considerable savings in their cost.

Pharmacokinetics and Tissue Distribution Study of Pinosylvin in Rats by Ultra-High-Performance Liquid Chromatography Coupled with Linear Trap Quadrupole Orbitrap Mass Spectrometry. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2018; 2018:4181084. [PMID: 30584452 PMCID: PMC6280233 DOI: 10.1155/2018/4181084] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2018] [Revised: 10/27/2018] [Accepted: 11/07/2018] [Indexed: 01/09/2023]
Abstract
Pinosylvin is a potential anti-inflammatory and antioxidant compound and the major effective medicinal ingredient in the root of Lindera reflexa Hemsl. However, few investigations have been conducted regarding the pharmacokinetics, excretion, characteristics of tissue distribution, and major metabolites of pinosylvin in rats after oral administration. To better understand the behavior and mechanisms of action underlying the activity of pinosylvin in vivo, we established a simple, sensitive, and reliable ultra-high-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method for quantifying pinosylvin in rat plasma, urine, feces, and various tissues (including heart, liver, spleen, lung, kidneys, large intestine, small intestine, and stomach). Noncompartmental pharmacokinetic parameters indicated that pinosylvin is rapidly distributed and taken up by tissues. The time to peak (maximum) concentration (Tmax) was 0.137 h, and the apparent elimination half-life (t1/2) was 1.347±0.01 h. The results of the tissue distribution study suggest that pinosylvin is widely distributed to various tissues; the highest concentration was observed after 10 min in the stomach, followed by the heart, lung, spleen, and kidneys. Results of the excretion study suggest that a small amount of pinosylvin is excreted from the urine and feces in the parent form; the 73 h accumulative excretion ratios of urine and feces were 0.82% and 0.11%, respectively. It is likely that pinosylvin is mostly metabolized in vivo. Nine metabolites were found, and the main metabolic pathways of pinosylvin in rats included glucuronidation, hydroxylation, and methylation. Four metabolites had higher concentrations in the stomach, suggesting that the stomach is a potential target organ of pinosylvin. In conclusion, the present study may provide a material basis for studying the pharmacological action of pinosylvin and provides meaningful information for the clinical treatment of chronic gastritis and gastric ulcers using Radix Linderae Reflexae.

[PMID: 29348751 PMCID: PMC5733964 DOI: 10.1155/2017/5178729] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2017] [Accepted: 07/02/2017] [Indexed: 12/17/2022] Open
Abstract
Two analytical platforms, gas chromatography (GC) coupled to quadrupole-time-of-flight (QTOF) mass spectrometry (MS) and reversed-phase ultrahigh performance liquid chromatography (UHPLC) coupled to diode array (DAD) and QTOF detection, were applied in order to study the alkaloid profile of Fumaria capreolata. The use of these mass analyzers enabled tentatively identifying the alkaloids by matching their accurate mass signals and suggested molecular formulae with those previously reported in libraries and databases. Moreover, the proposed structures were corroborated by studying their fragmentation pattern obtained by both platforms. In this way, 8 and 26 isoquinoline alkaloids were characterized using GC-QTOF-MS and RP-UHPLC-DAD-QTOF-MS, respectively, and they belonged to the following subclasses: protoberberine, protopine, aporphine, benzophenanthridine, spirobenzylisoquinoline, morphinandienone, and benzylisoquinoline. Moreover, the latter analytical method was selected to determine at 280 nm the concentration of protopine (9.6 ± 0.7 mg/g), a potential active compound of the extract. In conclusion, although GC-MS has been commonly used for the analysis of this type of phytochemicals, RP-UHPLC-DAD-QTOF-MS provided essential complementary information. This analytical method can be applied for the quality control of phytopharmaceuticals containing Fumaria extracts currently found in the market.

Metabolite identification and pharmacokinetic profiling of PP242, an ATP-competitive inhibitor of mTOR using ultra high-performance liquid chromatography and mass spectrometry. J Chromatogr B Analyt Technol Biomed Life Sci 2017; 1072:244-251. [PMID: 29195143 DOI: 10.1016/j.jchromb.2017.11.027] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Revised: 11/14/2017] [Accepted: 11/22/2017] [Indexed: 02/06/2023]
Abstract
PP242 is a second generation novel selective ATP-competitive inhibitor of mTOR that displayed promising anti-cancer activity over several cancer types by inhibiting both the complexes of mTOR (mTORC1 and mTORC2). The purpose of this study is to identify the possible metabolites and to evaluate the pharmacokinetic profile of PP242 after a single oral administration to Sprague-Dawley (SD) rats. Two metabolites, including one phase I and one phase II, were identified by in vitro and in vivo studies using rat liver microsomes (RLMs) as well as rat plasma, urine and feces, respectively, through ultra high-performance liquid chromatography-linear ion trap quadrupole-orbitrap-mass spectrometry (UHPLC-LTQ-Orbitrap-MS). The major biotransformation pathways of PP242 were hydroxylation and glucuronide conjugation. Additionally, a simple and rapid quantification method was developed and validated. The method recovery was within 79.7-84.6%, whereas the matrix effect was 78.1-96.0% in all three quality control (QC) concentrations (low, medium and high) including the LLOQ. Other parameters showed acceptable results according to the US food and drug administration (FDA) guidelines for bioanalytical method validation. Afterwards, pharmacokinetic parameters were evaluated in rat plasma by successfully applying the validated method using liquid chromatography-tandem mass spectrometry (LC-MS/MS). After a single oral administration at a dose of 5mg/kg, the maximum plasma concentration (Cmax) of PP242 was 0.17±0.08μg/mL, while the elimination was moderately fast (T1/2: 172.18±45.54min). All of the obtained information on the metabolite identification and pharmacokinetic parameter elucidation could facilitate the further development of PP242.

[PMID: 27394958 DOI: 10.1016/j.steroids.2016.07.002] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2016] [Revised: 06/14/2016] [Accepted: 07/04/2016] [Indexed: 10/21/2022]
Abstract
A sensitive and credible high performance liquid chromatography hyphenated to mass spectrometry (HPLC-MS/MS) was established to quantify the concentration of gracillin in rat plasma. The plasma samples were subjected to a direct protein precipitation process with acetonitrile as a precipitant in a single-step. Ginsenoside Rb1 was selected as an internal standard (IS). The chromatographic separation of analyte and IS were carried out on an Inersil ODS-3 C18 column (250×4.6mm, 5μm) with a binary solvent system containing acetonitrile and 0.1% formic acid in water at a flow rate of 1mLmin(-1) under a gradient elution mode. Mass spectrometric detection was performed on a triple quadrupole tandem mass spectrometer by the multiple reaction monitoring (MRM) mode to examine the precursor-to-daughter ion transitions of 1110.3→948.2 for IS and 886.1→739.9 for gracillin, respectively, in a positive electrospray ionization mode. The calibration curve showed a promising linearity over a concentration range of 0.065-800ngmL(-1) with a better regression coefficient of r(2)=0.9960. The intra- and inter-day precisions (as relative standard deviation) of the assay at three quality control levels were all less than 3.48%, while the intra- and inter-day accuracies (as relative error) ranged from -8.43% to 9.74%, whose data were within the acceptable limits. The mean extraction recoveries of analyte from rat plasma were all more than 74.11%, and no notable matrix effect was observed. Stability experiments revealed that gracillin remained stable throughout the analytical procedure under various stored conditions. The above validated method was successfully used to investigate the pharmacokinetic behaviors of gracillin orally administrated to rats at three proportion doses. The pharmacokinetic analysis would pave the way for understanding the pharmacological actions and provide a meaningful foundation for further development and application in preclinical and clinical use of gracillin in the near future.
