Nat Prod Res 2024:1-6. [PMID: 39092521 DOI: 10.1080/14786419.2024.2387252] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 07/08/2024] [Accepted: 07/28/2024] [Indexed: 08/04/2024]
Abstract
This study aims to assess hepatoprotective properties of M. rotundifolia. Decoction was used to prepare the aqueous extract. The preliminary cytotoxicity evaluated against Caco 2 and RAW 264 cells demonstrate no cytotoxic effect. The preventive impact of the extract against liver damage was evaluated by examining blood levels of AST, ALT, ALP, total proteins, and histological alterations in liver tissues. Thirty albino rats were separated into five groups: the first served as normal group, the second was injected by olive oil (3 ml/kg), and the third was injected by CCL4 (3 ml/kg). However, groups IV and V received daily doses of 250 and 500 mg extract/kg bw, respectively before CCL4 injection. The results showed that the administration of the extract led to a marked improvement in plasma biochemical markers and a reduction in symptoms of CCL4-induced liver damage. The extract exhibits hepatoprotective activity, which may be attributed to its phytochemical components.

Abstract
The pharmacological activities of dictamnine and fraxinellone have been well reported; however, only a few studies have focused on the pharmacokinetics and bioavailability of concomitant delivery of these drugs in vivo. To shed light on this neglected area, we developed a rapid and sensitive UPLC-MS/MS method that quantified the levels of dictamnine and fraxinellone simultaneously in rat plasma. This method was initiated by a one-step protein precipitation strategy to purify plasma samples collected from rats treated with either oral or intravenous administration of dictamnine and fraxinellone. The mobile phase contained acetonitrile and 0.1% formic acid at a steady flow rate of 0.6 mL/min. As a result, an excellent analyte peak resolution was achieved, and the entire process took only 3 min per sample. The results were indicative of the desired linearity (r2 ≥ 0.999), precision (RSD% was within 15%), accuracy (RE% was within 15%), recoveries (≥80.66 and 68.15% for dictamnine and fraxinellone, respectively) and matrix effects (≥94.66 and 91.37% for dictamnine and fraxinellone, respectively). Additionally, the detectable limits of these two compounds were both low even when they reached 5 ng/mL. Taken together, these findings contribute to a better understanding of the pharmacokinetics and bioavailability properties of concomitant delivery of dictamnine and fraxinellone.

Abstract
Abstract
Background
Carbon tetrachloride (CCl4) is a well-characterized hepatotoxic agent. With rising cases of liver diseases, the identification, assessment, and development of hepatoprotective agents from plants source has become imperative.
Main body
With arrays of literature on plants with hepatoprotective potentials, this review sourced published literatures between 1998 and 2020 and systematically highlighted about 92 medicinal plants that have been reported to protect against CCl4-induced liver injury in animal models. The results show that herbal plants provide protection for the liver against CCl4 by downregulation of the liver marker enzymes and activation of antioxidant capacity of the liver cells with the restoration of liver architecture. We also provided the traditional and accompanying pharmacological uses of the plants. A variety of phytochemicals mostly flavonoids and polyphenols compounds were suggested to offer protection against liver injuries.
Conclusion
It can be concluded that there are a variety of phytochemicals in plant products with hepatoprotective activity against CCl4-induced toxicity in animal models.

Abstract
Anaphylactoid reactions are potentially fatal allergic diseases caused by mast cells (MCs), which release histamine and lipid mediators under certain stimuli. Therefore, there is an urgent need to develop new drug candidates to treat anaphylactoid reactions. The MrgX2 receptor mediates anaphylactoid reactions that cause inflammatory diseases. Cortex dictamni is a Chinese herb used for treating allergy-related diseases; however, its active compound is still unknown and its mechanism of action has not yet been reported. The aim of this study was to screen the anti-anaphylactoid compound from C. dictamni extracts. An MrgX2/CMC-HPLC method was established for screening MrgX2-specific compounds retained from the alcohol extract of C. dictamni. A mouse model of hindpaw extravasation was used to evaluate the anti-anaphylactoid effect of this ingredient. Intracellular Ca2+ mobilization was assessed using a calcium imaging assay. Enzyme immunoassays were performed to measure cytokine and chemokine release levels. The molecular signaling pathways were explored by western blotting. As a result, dictamnine was identified as an effective compound using the MrgX2/CMC method, which remarkably suppressed MC intracellular Ca2+ mobilization and the release of de novo degranulated substances, and inhibited PKC-PLCγ-IP3R-associated protein signaling molecules. Hence, dictamnine is a novel therapeutic candidate for anaphylactoid reactions via MrgX2.

Abstract
Objectives To investigate the neuroprotective effects of six natural compounds
(caffeine, gallic acid, resveratrol, epigallocatechin gallate [EGCG],
L-ascorbic acid and alpha tocopherol [Vitamin E] on heavy metal-induced cell
damage in rat PC12 cells. Methods In this in vitro experiment, rat PC12 cells were exposed to
four heavy metals (CdCl2, HgCl2, CoCl2 and
PbCl2) at different concentrations and cell apoptosis,
necrosis and oxidative stress were assessed with and without the addition of
the six natural compounds. Results The metals decreased cell viability but the natural compounds attenuated
their effects on apoptosis, necrosis and reactive oxygen species (ROS)
levels. Mitochondrial protein changes were involved in the regulation. Conclusion Overall, the natural compounds did provide protection against the
metal-induced PC12 cell damage. These data suggest that natural compounds
may have therapeutic potential against metal-induced neurodegenerative
disease.

Abstract
Quality inconsistency of herbal medicine is an obstacle that limits the extensive use and study of traditional Chinese medicine. Differences in environmental conditions and processing methods of herbal medicine often result in varying clinical outcomes in patients. Standard chemical markers used for the quality control (QC) of herbal medicine are usually the most abundant and characteristic components, which may not be therapeutically relevant or cannot comprehensively reflect the biological quality of the herbs. In view of this, a novel QC method for better assessment of herbal medicine has been developed via bioactivities analysis. Immunological activities of Dictamni Cortex, a typical herbal medicine for the treatment of various inflammatory diseases, from different geographical locations in China, were evaluated. Upon in vitro treatment of their water and ethanol extracts, distinct patterns of inflammatory cytokines including tumor necrosis factor (TNF)-α, interleukin (IL)-10, IL-6, IL-12p70, IL-1β, and chemokine CXCL8 were released from the lipopolysaccharides- and/or phytohaemagglutinin-stimulated human peripheral blood mononuclear cells (PBMC). Thus, in addition to the commonly used morphological, chemical, or DNA markers, the novel high-throughput profiling of inflammatory cytokines and chemokines of PBMC upon treatment with herbal extracts could be an important reference to help for the quality control of herbal medicine in the future.

Pre-treatment with a combination of Shenmai and Danshen injection protects cardiomyocytes against hypoxia/reoxygenation- and H 2O 2-induced injury by inhibiting mitochondrial permeability transition pore opening. Exp Ther Med 2019; 17:4643-4652.

Abstract
Increasing evidence has indicated that opening of the mitochondrial permeability transition pore (mPTP) has a vital role in myocardial ischemia/reperfusion (I/R) injury. Shenmai injection (SMI) plus Danshen injection (DSI) combination, termed Yiqi Yangyin Huoxue (YYH) therapy is used in the clinic to treat cardiovascular diseases, including myocardial I/R injury. Previous studies by our group have demonstrated the protective effect of pretreatment with YYH against myocardial I/R injury in isolated rat hearts. The present study aimed to examine the protective effect of YYH against hypoxia/reoxygenation (H/R)- and H2O2-induced cardiomyocyte injury, and to determine whether this effect is produced by inhibition of mPTP opening. Primary cardiomyocytes isolated from neonatal rats were cultured and randomly grouped into a control group, injury group and pretreatment group, with six duplicated wells in each group during each assay. Cardiomyocytes in the injury group were subjected to H/R to simulate I/R or exposed to H2O2 for 2 h to induce oxidative injury. Cellular injury was assessed via release of creatine kinase (CK) and lactate dehydrogenase (LDH), and cell viability was measured by an MTT assay. The mitochondrial membrane potential (ΔΨm) and cytosolic reactive oxygen species (ROS) were detected using the fluorescent probes rhodamine123 (Rh123) and chloromethyl-2,7-dichlorodihydrofluorescein diacetate (CM-H2DCFDA), respectively. Intracellular Ca2+, mitochondrial Ca2+ and mPTP opening were measured using fluo-4 acetoxymethyl (Fluo-4/AM), rhodamine-2 acetoxymethyl (Rhod-2/AM) and calcein acetoxymethyl (Calcein/AM) probes, respectively. The results indicated that pretreatment with YYH enhanced cell viability, increased ΔΨm, reduced CK and LDH release, and decreased intracellular ROS and Ca2+, thus reducing cardiomyocyte injury induced by H/R or H2O2. LY294002, a specific phosphoinositide 3-kinase (PI3K) inhibitor, and PD98059, a specific inhibitor of the extracellular signal-regulated kinase 1/2 (Erk1/2) pathway, eliminated the protective effects of the combination therapy on cell viability and the change in the ΔΨm in cardiomyocytes. In conclusion, pre-treatment with YYH has cardioprotective effects against H/R injury and oxidative stress via activation of the PI3K/Akt and Erk1/2 signaling pathways, which reduces mPTP opening, overproduction of ROS and calcium overload.

ScientificWorldJournal 2019; 2019:5236851. [PMID: 30940993 PMCID: PMC6421029 DOI: 10.1155/2019/5236851] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2018] [Revised: 01/30/2019] [Accepted: 02/10/2019] [Indexed: 12/11/2022] Open
Abstract
Background Liver diseases are a global health problem. Medicinal plants are being increasingly used to manage a wide variety of diseases including liver disorders. The aim of this study was to investigate the antioxidant properties and hepatoprotective activity of polyphenolic extract from the fruits of Tetrapleura tetraptera (T. tetraptera). Results The extract of T. tetraptera was administered at doses of 50 mg/kg and 100 mg/kg for 07 per os to rats before the induction of hepatotoxicity with of 2 ml/kg of 1:1 (v/v) carbon tetrachloride (CCl4) and olive oil through intraperitoneal route. The in vitro antioxidant and radical scavenging properties of T. tetraptera were conducted by the FRAP method, the phosphomolybdate method, and the inhibition potential of DPPH, ABTS, OH, and NO radicals. The extraction yield of T. tetraptera was 19.35%. This extract contains polyphenols (273.48 mg CAE/g DM), flavonoids (5.2549 mg SE/g DM), and flavonols (1.615 mg SE/g DM). This extract showed in vitro antioxidant activity, an inhibitor power of various free radicals, and radical scavenging potential dose-dependent. The fifty-percent inhibitory concentration of the extract (IC50) for the studied radical varied from 28.16 to 136 μg/L. In rats treated with the extract of T. tetraptera, in a dose-dependent manner, the levels of hepatotoxicity markers such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) significantly increased while the enzyme activities of superoxide dismutase (SOD), catalase (CAT), and the level of reduced glutathione (GHS) significantly increased compared to the control group. Conclusions The extracts from the fruit of T. tetraptera demonstrate antioxidant activity and hepatoprotective effects.

Protective effects of Gastrodia elata Blume on acetaminophen-induced liver and kidney toxicity in rats. Food Sci Biotechnol 2018; 27:1445-1454. [PMID: 30319855 DOI: 10.1007/s10068-018-0374-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2018] [Revised: 03/17/2018] [Accepted: 04/03/2018] [Indexed: 10/16/2022] Open
Abstract
An overdose of acetaminophen (AAP) causes hepatic and renal toxicity. This study examined the protective effects of Gastrodia elata Blume (GEB) on hepatic and renal injury induced by AAP. Rats were orally administered distilled water or GEB for 14 days and injected with AAP 1 h after the oral last administration; control rats were administered water without AAP injection. All rats were sacrificed 24 h after AAP injection. The GEB pretreatment group showed decreased necrosis and the expression of pro-inflammatory cytokines in the liver and kidney. TUNEL-positive cells and oxidative stress marker, such as malondialdehyde, were decreased. However, antioxidant enzymes, such as glutathione and superoxide dismutase, were increased. The expression of CYP2E1 and N-acetyl-beta-d-glucosaminidase was decreased in the GEB pretreatment group. This study shows that GEB prevents AAP-induced liver and kidney injury.

Abstract
During our study on the bioactivities of natural flavonoids, we found that the total flavonoids (TFs) and the main constituent of it, licochalcone A (lico A), activated unfolded protein response (UPR) and induced autophagy and thereby apoptosis in H292 cells. MicroRNAs, such as the tumor repressor miR-144-3p, were reported to be differentially expressed in lung cancer cells and were linked to ER stress, autophagy, and apoptosis. However, the underlying miRNA-based mechanism for lico A modulating proliferation, autophagy and apoptosis in lung cancer cells is elusive. In this study, we found that miR-144-3p was down-regulated in H292 cells comparing to normal embryonic lung cells WI-38, and lico A (10 μM) could increase miR-144-3p level in H292 cells. Knockdown of miR-144-3p significantly abrogated the apoptosis and proliferation-inhibiting effects of lico A, and lico A could enhance the proliferation-inhibiting effect and apoptosis induced by miR-144-3p overexpression. Moreover, overexpression miR-144-3p could induce ER stress by down-regulating Nrf2, and lico A enhanced the Nrf2 down-regulation caused by miR-144-3p overexpression. Co-transfection experiments showed that lico A potentially increased the dicing of pre-miR-144 so as to increase the mature miR-144-3p level. Interestingly, high level of lico A (40 μM) up-regulated CHOP protein, but failed to increase the downstream genes levels of CHOP, including Bim and Bcl-2 in H292 cells. Docking studies indicated that CHOP-mediated pathway was potentially blocked by high dose of lico A. Our results suggested that lico A could cause UPR, autophagy and apoptosis, and the underlying mechanism involved up-regulation of miR-144-3p, and increased lico A level would also increase the potential for lico A inhibiting CHOP-dependent apoptosis in H292 cells.

Abstract
Airway smooth muscle (ASM) is a prominent effecter in maintaining bronchial muscle contraction and responsible for airway hyper-responsiveness (AHR); the phenotype change and over-proliferation of airway smooth muscle cells (ASMCs) play key roles in the pathogenesis of asthma. The aim of this study was to investigate the anti-proliferation effects of Cortex Dictamni aqueous extract (CDAE) and ethanol extract (CDE) on ASMCs and the possible underline mechanisms. Cell proliferation rates were determined by MTT assay; matrix metalloproteinases-2 (MMP-2) activity was examined by gelatin zymography; cell proliferation and migration were appraised by in-vitro cell-gap closure assessment; protein expressions of p38, Bcl-2 and FAK of ASMCs were evaluated by western blotting and Ca2+ influx of cells was measured by confocal laser microscope. Our data demonstrated that the proliferation, migration and MMP-2 expressions of ASMCs were inhibited by CDAE or CDE; the protein expressions of p38, Bcl-2 and FAK in ASMCs were substantially reduced by CDAE and CDE detected by western blotting or immunocytochemistry; also the increased calcium influx has been observed instantaneously after ASMCs were stimulated by CDAE or CDE. These findings suggested that Cortex Dictamni extracts might have inhibitory effects on ASMCs over-proliferation which could be one of the underline mechanisms for the therapy of asthma.
