Exploring the composition and properties of Centella asiatica metabolites and investigating their impact on BSA glycation, LDL oxidation and α-amylase inhibition. J Pharm Biomed Anal 2024; 245:116143. [PMID: 38678859 DOI: 10.1016/j.jpba.2024.116143] [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: 12/21/2023] [Revised: 03/26/2024] [Accepted: 03/31/2024] [Indexed: 05/01/2024]
Abstract
Centella asiatica (L.) Urb. is a small herbaceous plant belonging to the Apiaceae family that is rich in triterpenes, such as asiaticoside and madecassoside. Centella asiatica finds broad application in promoting wound healing, addressing skin disorders, and boosting both memory and cognitive function. Given its extensive therapeutic potential, this study aimed not only to investigate the Centella asiatica ethanolic extract but also to analyze the biological properties of its organic fractions, such as antioxidant antiglycation capacity, which are little explored. We also identified the main bioactive compounds through spectrometry analysis. The ethanolic extract (EE) was obtained through a static maceration for seven days, while organic fractions (HF: hexane fraction; DF: dichloromethane fraction; EAF: ethyl acetate fraction; BF: n-butanol fraction and HMF: hydromethanolic fraction) were obtained via liquid-liquid fractionation. The concentration of phenolic compounds, flavonoids, and tannins in each sample was quantified. Additionally, the antiglycation (BSA/FRU, BSA/MGO, and ARG/MGO models) and antioxidant (FRAP, ORAC, and DPPH) properties, as well as the ability to inhibit LDL oxidation and hepatic tissue peroxidation were evaluated. The inhibition of enzyme activity was also analyzed (α-amylase, α-glycosidase, acetylcholinesterase, and butyrylcholinesterase). We also evaluated the antimicrobial and cytotoxicity against RAW 264.7 macrophages. The main compounds present in the most bioactive fractions were elucidated through ESI FT-ICR MS and HPLC-ESI-MS/MS analysis. In the assessment of antioxidant capacity (FRAP, ORAC, and DPPH), the EAF and BF fractions exhibited notable results, and as they are the phenolic compounds richest fractions, they also inhibited LDL oxidation, protected the hepatic tissue from peroxidation and inhibited α-amylase activity. Regarding glycation models, the EE, EAF, BF, and HMF fractions demonstrated substantial activity in the BSA/FRU model. However, BF was the only fraction that presented non-cytotoxic activity in RAW 264.7 macrophages at all tested concentrations. In conclusion, this study provides valuable insights into the antioxidant, antiglycation, and enzymatic inhibition capacities of the ethanolic extract and organic fractions of Centella asiatica. The findings suggest that further in vivo studies, particularly focusing on the butanol fraction (BF), may be promising routes for future research and potential therapeutic applications.

[PMID: 38597444 PMCID: PMC11006695 DOI: 10.12122/j.issn.1673-4254.2024.03.14] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Indexed: 04/11/2024]
Abstract
OBJECTIVE To investigate the effect of asiaticoside on blood pressure and relaxation of thoracic aorta in rats and explore the underlying mechanism. METHODS SD rats treated with 50 and 100 mg/kg asiaticoside by daily gavage for 2 weeks were monitored for systolic blood pressure changes, and histological changes of the thoracic aorta were evaluated using HE staining. In isolated rat endothelium-intact and endothelium-denuded thoracic aorta rings, the effects of asiaticoside on relaxation of the aortic rings were tested at baseline and following norepinephrine (NE)- and KCl-induced constriction. The vascular relaxation effect of asiaticoside was further observed in NE-stimulated endothelium-intact rat aortic rings pretreated with L-nitroarginine methyl ester, indomethacin, zinc protoporphyrin Ⅸ, tetraethyl ammonium chloride, glibenclamide, barium chloride, Iberiotoxin, 4-aminopyridine, or TASK-1-IN-1. The aortic rings were treated with KCl and NE followed by increasing concentrations of CaCl2 to investigate the effect of asiaticoside on vasoconstriction induced by external calcium influx and internal calcium release. RESULTS Asiaticoside at 50 and 100 mg/kg significantly lowered systolic blood pressure in rats without affecting the thoracic aorta histomorphology. While not obviously affecting resting aortic rings with intact endothelium, asiaticoside at 100 mg/kg induced significant relaxation of the rings constricted by KCl and NE, but its effects differed between endothelium-intact and endothelium-denuded rings. In endothelium-intact aortic rings pretreated with indomethacin, ZnPP Ⅸ, barium chloride, glyburide, TASK-1-IN-1 and 4-aminopyridine, asiaticoside did not produce significant effect on NE-induced vasoconstriction, and tetraethylammonium, Iberiotoxin and L-nitroarginine methyl ester all inhibited the relaxation effect of asiaticoside. In KCland NE-treated rings, asiaticoside obviously inhibited CaCl2-induced vascular contraction. CONCLUSION Asiaticoside induces thoracic aorta relaxation by mediating high-conductance calcium-activated potassium channel opening, promoting nitric oxide release from endothelial cells and regulating Ca2+ influx and outflow, thereby reducing systolic blood pressure in rats.

[PMID: 38007481 PMCID: PMC10676574 DOI: 10.1186/s40360-023-00701-x] [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: 02/23/2023] [Accepted: 10/31/2023] [Indexed: 11/27/2023] Open
Abstract
BACKGROUND Atherosclerosis is a form of cardiovascular disease that affects the endothelium of the blood vessel. Series of events are involved in the pathophysiology of this disease which includes the breaking down of the connective tissue elastin and collagen responsible for the tensile strength of the arterial wall by proteolytic enzyme. One of these enzymes called Cathepsin S (CatS) is upregulated in the progression of the disease and its inhibition has been proposed to be a promising pharmacological target to improve the prognosis of the disease condition. Asiatic acid and asiaticoside A are both pentacyclic triterpenoids isolated from Centella asiatica. Their use in treating various cardiovascular diseases has been reported. METHODS In this study through in silico and in vitro methods, the pharmacokinetic properties, residue interaction, and inhibitory activities of these compounds were checked against the CatS enzyme. The SwissADME online package and the ToxTree 3.01 version of the offline software were used to determine the physicochemical properties of the compounds. RESULT Asiatic acid reported no violation of the Lipinski rule while asiaticoside A violated the rule with regards to its molecular structure and size. The molecular docking was done using Molecular Operating Environment (MOE) and the S-score of - 7.25988, - 7.08466, and - 4.147913 Kcal/mol were recorded for LY300328, asiaticoside A, and asiatic acid respectively. Asiaticoside A has a docking score value (- 7.08466Kcal/mol) close to the co-crystallize compound. Apart from the close docking score, the amino acid residue glycine69 and asparagine163 both interact with the co-crystallized compound and asiaticoside A. The in vitro result clearly shows the inhibitory effect of asiaticoside and asiatic acid. Asiaticoside A has an inhibitory value of about 40% and asiatic acid has an inhibitory value of about 20%. CONCLUSION This clearly shows that asiaticoside will be a better drug candidate than asiatic acid in inhibiting the CatS enzyme for the purpose of improving the outcome of atherosclerosis. However, certain modifications need to be made to the structural make-up of asiaticoside A to improve its pharmacokinetics properties.

Asiaticoside Increases Caspase-9 Activity in MCF-7 Cells and Inhibits TNF-α and IL-6 Expression in Nude Mouse Xenografts via the NF-κB Pathway. Molecules 2023; 28:molecules28052101. [PMID: 36903346 PMCID: PMC10003851 DOI: 10.3390/molecules28052101] [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: 02/09/2023] [Revised: 02/21/2023] [Accepted: 02/22/2023] [Indexed: 02/26/2023] Open
Abstract
Background: We hypothesized that the antitumor effects of asiaticoside on breast cancer are driven by its ability to decrease the expression of tumor inflammation-promoting genes and increase apoptotic signaling. In this study, we aimed to better understand the mechanisms of action of asiaticoside as a chemical modulator or as a chemopreventive agent in breast cancer. Methods: MCF-7 cells were cultured and treated with 0, 20, 40, and 80 μM asiaticoside for 48 h. Fluorometric caspase-9, apoptosis, and gene expression analyses were conducted. For the xenograft experiments, we divided nude mice into the following 5 groups (10 animals per group): group I, control mice; group II, untreated tumor-bearing nude mice; group III, tumor-bearing nude mice treated with asiaticoside at weeks 1-2 and 4-7 and injected with MCF-7 cells at week 3; group IV, tumor-bearing nude mice injected with MCF-7 cells at week 3 and treated with asiaticoside beginning at week 6; and group V, nude mice treated with asiaticoside, as a drug control. After treatment, weight measurements were performed weekly. Tumor growth was determined and analyzed using histology and DNA and RNA isolation. Results: In MCF-7 cells, we found that asiaticoside increased caspase-9 activity. In the xenograft experiment, we found that TNF-α and IL-6 expression decreased (p < 0.001) via the NF-κB pathway. Conclusion: Overall, our data suggest that asiaticoside produces promising effects on tumor growth, progression, and tumor-associated inflammation in MCF-7 cells as well as a nude mouse MCF-7 tumor xenograft model.

Abstract
The aim of this study was to investigate the underlying protective mechanisms of asiaticoside (AS) against liver fibrosis (LF) both in vivo and in vitro. A rat model with carbon tetrachloride (CCl4)-induced liver fibrosis is employed to verify the effect and mechanism of AS on the process of liver fibrosis in vivo experiment. Hematoxylin/eosin and sirius red staining was conducted to assess the severity of liver injury and fibrosis. Further, the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), glutamyl transferase (GGT), and total bilirubin (TBil) were measured. In addition, LX2 cells were cultured for vitro experiment to investigate the influence of AS on hepatic stellate cells (HSCs). Overproduction of α-smooth muscle actin and type I collagen is characteristic of LF and HSCs, as determined by immunohistochemical and Western blot analyses. The expression levels of molecules associated with the Notch signaling pathway (i.e., Notch-1, Jagged-1, and Delta-like-4) were assessed by Western blot analysis. The results revealed that AS attenuated LF, as defined by reduced deposition of collagen, expression of α-smooth muscle actin and collagen type 1, and expression of biochemical parameters (alanine aminotransferase, aspartate aminotransferase, and hydroxyproline). Notably, AS suppressed the expression levels of Notch-1, Jagged-1, and Delta-like-4 in activated HSCs and LF. Collectively, these results demonstrate that AS prevented the progression of LF by modulating the Notch signaling pathway, indicating that AS has potential therapeutic effects against LF.

Asiaticoside alleviates cardiomyocyte apoptosis and oxidative stress in myocardial ischemia/reperfusion injury via activating the PI3K-AKT-GSK3β pathway in vivo and in vitro. ANNALS OF TRANSLATIONAL MEDICINE 2022; 10:69. [PMID: 35282120 PMCID: PMC8848378 DOI: 10.21037/atm-21-6667] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Accepted: 01/11/2022] [Indexed: 12/16/2022]
Abstract
Background Myocardial ischemia/reperfusion (MI/R) is one of the most important links in myocardial injury, causing damage to cardiac tissues including cell apoptosis, oxidative stress, and other serious consequences. Asiaticoside (AS), a new compound synthesized from genistein, is cardioprotective. This paper presents new evidence for the protective role of AS against MI/R injury in vitro and in vivo. Methods First, BALB/c mice underwent surgical ligation of the left anterior descending (LAD) artery to establish an MI/R animal model, and HL-1 cells were subjected to oxygen-glucose deprivation/reperfusion (OGD/R) to establish an in vitro model. Myocardial infarct size was examined by triphenyl tetrazolium chloride (TTC) staining, histopathological changes detected in heart tissues were observed using hematoxylin and eosin (H&E) and Masson staining, heart tissue apoptosis was assessed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining. Enzyme-linked immunosorbent assay (ELISA) kits were used to analyze cardiac troponin I (CTnI), creatine kinase-muscle and brain (CK-MB), lactate dehydrogenase (LDH), superoxide dismutase (SOD), malondialdehyde (MDA), and reduced glutathione (GSH). Cell viability was evaluated using Cell Counting Kit-8 (CCK-8) and live/dead assay. Cell apoptosis, reactive oxygen species (ROS), mitochondrial membrane potential, and mitochondrial superoxide were detected by flow cytometry and fluorescence microscopy. Both the protein expression in myocardial tissues and cardiomyocytes were examined by western blot. Results In the in vivo MI/R experiments,pretreatment of AS reduced myocardial infarct size, decrease leakage of myocardial enzyme, suppressed myocardial apoptosis, myocardial collagen deposition, and oxidative stress. In the in vitro OGD/R experiments, HL-1 cells pretreated with AS had increased cell viability, decreased apoptosis rates and depolarization of mitochondrial membrane potential, and attenuated intracellular ROS and mitochondrial superoxide. Moreover, AS downregulated the expression of apoptotic protein, and promoted phosphorylation of PI3K, AKT, and GSK3β, which was reversed by PI3K inhibitor LY294002. Conclusions The AS compound protects against MI/R injury by attenuating oxidative stress and apoptosis via activating the PI3K/AKT/GSK3β pathway in vivo and vitro.

Abstract
The medicinal herb Centella asiatica (L.) Urban known as gotu kola has been reported to exhibit a wide range of pharmacological activities. In particular, a significant body of scientific research exists on the therapeutic properties of preparations of C. asiatica or its triterpenes in the treatment of skin diseases. The present study is aimed to provide a comprehensive overview of the beneficial effects of C. asiatica on skin diseases. Peer-reviewed articles on the potent dermatological effects of C. asiatica were acquired from PubMed, Web of Science, Scopus, ScienceDirect, and SciFinder. This review provides an understanding of pharmacological studies which confirm the potent dermatological effects and underlying molecular mechanisms of C. asiatica. This medicinal plant and its triterpenes include asiaticoside, madecassoside, and their aglycones, asiatic acid and madecassic acid. These compounds exert therapeutic effects on dermatological diseases such as acne, burns, atopic dermatitis, and wounds via NF-κB, TGF-β/Smad, MAPK, Wnt/β-catenin, and STAT signaling in in vitro and in vivo studies. However, additional rigorously controlled long-term clinical trials will be necessary to confirm the full potential of C. asiatica as a therapeutic agent.

Abstract
Centella asiatica is a popular herb well-known for its wide range of therapeutic effects and its use as a folk medicine for many years. Its therapeutic properties have been well correlated with the presence of asiaticoside, madecassoside, asiatic and madecassic acids, the pentacyclic triterpenes. The herb has been extensively known to treat skin conditions; nevertheless, several pre-clinical and clinical studies have scientifically demonstrated its effectiveness in other disorders. Among the active constituents that have been identified in Centella asiatica, madecassoside has been the subject of only a relatively small number of scientific reports. Therefore, this review, while including other major constituents of this plant, focuses on the therapeutic potential, pharmacokinetics and toxicity of madecassoside.

Abstract
Centella asiatica (also known as Centella asiatica (L.) Urb. or Gotu kola) is a traditional Chinese medicine with extensive medicinal value, which is commonly used in Southeast Asian countries. This study aimed to summarize the effects of C. asiatica and its main components on neurological diseases, endocrine diseases, skin diseases, cardiovascular diseases, gastrointestinal diseases, immune diseases, and gynecological diseases, as well as potential molecular mechanisms, to study the pathological mechanism of these diseases based on the changes at the molecular level. The results showed that C. asiatica and its triterpenoids had extensive beneficial effects on neurological and skin diseases, which were confirmed through clinical studies. They exhibited anti-inflammatory, anti-oxidative stress, anti-apoptotic effects, and improvement in mitochondrial function. However, further clinical studies are urgently required due to the low level of evidence and lack of patients.

Abstract
Oxidized low-density lipoprotein (ox-LDL) was known to induce endothelial cell injury to the progression of atherosclerosis (AS). Sophocarpine (SPC), a compound of sophora alkaloids isolated from the plant Sophora alopecuroides, has been shown to exhibit various pharmacological activities. This study was designed to investigate the protective effect of SPC on ox-LDL-induced endothelial cells and explored its underlying mechanism. Our results show that SPC pre-incubation ameliorated ox-LDL-mediated HAECs cytotoxicity, DNA fragmentation, and apoptosis in a dose-dependent manner. Moreover, SPC significantly downregulated the mRNA or protein expression level of pro-inflammatory mediators (TGF-β, IL-6, IL-1β, TNF-α) and pro-inflammatory vascular adhesion molecules (VCAM-1, ICAM-1, and E-selectin). Mechanistically, SPC pre-treatment downregulated IκBα expression and inhibited translocation of NF-κB in ox-LDL-mediated HAECs, overexpression of NF-κB p65 counteracted the cytoprotective and anti-apoptotic effect of SPC, suggesting that its action is dependent on NF-κB signaling pathway. Collectively, SPC suppresses ox-LDL-induced HAECs injury by inhibiting the NF-κB signaling pathway.

Abstract
Background Neonatal hypoxic ischemic encephalopathy (HIE) is currently a leading cause of neonatal death. Asiaticoside (AT), a bioactive constituent isolated from Centella asiatica, possesses numerous biological properties. For instance, previous studies showed that AT could protect ischemia hypoxia neurons by mediating BCL-2 protein. However, the roles and underlying mechanisms of AT in neonatal HIE have not been clarified. Methods Rice-Vannucci was applied to construct a hypoxic-ischemic brain damage (HIBD) model. Pathological damage of brain neuron tissue was determined by hematoxylin-eosin (HE) staining, while apoptosis was evaluated by terminal-deoxynucleoitidyl transferase nick end labeling (TUNEL) staining. Western blot and immunohistochemistry were applied to monitor related proteins levels. Enzyme-linked immunosorbent assay (ELISA) was conducted to measure the expression levels of inflammatory cytokines. Results The present study indicated that AT dose-dependently ameliorated histologic damage and inhibited apoptosis induced by hypoxic ischemia (HI) (P<0.01). AT also dose-dependently alleviated oxidative damage and reduced the levels of proinflammatory cytokines (ICAM-1, IL-18, and IL-1β) and TLR4 level. In terms of mechanism, decrease of TLR and IL-18 suppressed NF-κB phosphorylation and reduced the levels of TNFα, IL-6, and p-STAT3, leading to the inactivation of NF-κB/STAT3 pathway. Interestingly, with the addition of lipopolysaccharide (LPS), the increase of TLR4 activated NF-κB/STAT3 pathway again. Conclusions Collectively, the data provide insight into a novel mechanism by which AT may be an effective agent for HIE via the TLR4/NF-κB/STAT3 pathway.

Abstract
Asiaticoside (AS), one of the main functional components of Centella asiatica, has been reported to protect neurons from ischemia-hypoxia-induced injury. However, the role of AS in myocardial oxygen-glucose deprivation/reoxygenation (OGD/R) injury has not been investigated. The aim of this study was to investigate the role of AS in OGD/R-treated H9c2 cardiomyocytes and the underlying mechanism involved. Cell viability was detected using MTT assay. Cell apoptosis was measured using flow cytometry. The oxidative stress was assessed by detecting the malonaldehyde (MDA) content and activities of superoxide dismutase, glutathione peroxidase, and catalase (CAT). The glucose consumption and lactate production were determined to reflect glycolysis rate. The expression levels of hexokinase II (HK2) were detected using reverse transcription quantitative polymerase chain reaction and Western blot. H9c2 cells were transfected with small interfering RNA targeting HK2 (si-HK2) to knockdown HK2. Results showed that AS improved cell viability and inhibited apoptosis in OGD/R-injured H9c2 cells. AS pretreatment prevented OGD/R-induced oxidative stress, as evidenced by the decreased MDA content, and increased activities of superoxide dismutase, glutathione peroxidase, and CAT. The decreased glucose consumption and lactate production in OGD/R-injured H9c2 cells were reversed after AS treatment. Mechanically, AS induced the expression of HK2 in OGD/R-injured H9c2 cells. Knockdown of HK2 abolished the protective effects of AS on OGD/R-injured H9c2 cells. In conclusion, the protective effects of AS on cardiomyocytes from OGD/R-induced injury were mediated at least partly by upregulating HK2.
