Abstract
High dose of fluoride intake is associated with toxic effects on kidney and cardiac tissues. This study evaluated the potential protective effect of fermented rooibos tea (RTE) on sodium fluoride (NaF)-induced cardiorenal toxicity in rats. Male Wistar rats (n = 56) were randomly allocated into one of seven equal groups: control, NaF (100 mg/kg orally), NaF + RTE (2%, w/v), NaF + RTE (4%, w/v), NaF + lisinopril (10 mg/kg orally), 2% RTE, and 4% RTE. The experiment lasted for 14 days and RTE was administered to the rats as their sole source of drinking fluid. NaF induced cardiorenal toxicity indicated by elevated level of urea, creatinine, LDH, creatinine kinase-MB, and cardiac troponin I in the serum, accompanied by altered histopathology of the kidney and heart. Furthermore, levels of H2O2, malondialdehyde, and NO were elevated, while GSH level was depleted in the kidney and heart due to NaF intoxication. Protein levels of c-reactive protein, TNFα, IL-1B, and NF-κB were increased by NaF in the serum, kidney, and heart. RTE at 2% and 4% (w/v) reversed cardiorenal toxicity, resolved histopathological impairment, attenuated oxidative stress and inhibited formation of pro-inflammatory markers. RTE at both concentrations down-regulates the mRNA expression of NF-κB, and upregulates the mRNA expression of both IκB and IκKB, thus blocking the activation of NF-κB signaling pathway. Taken together, these results clearly suggest that the protective potential of rooibos tea against NaF-induced cardiorenal toxicity, oxidative stress, and inflammation may be associated with the modulation of the NF-κB signaling pathway.

Systematic elucidation of the multi-target pharmacological mechanism of Terminalia arjuna against congestive cardiac failure via network pharmacology and molecular modelling approaches. Nat Prod Res 2023; 37:3733-3740. [PMID: 37665010 DOI: 10.1080/14786419.2023.2252565] [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: 04/15/2023] [Revised: 08/12/2023] [Accepted: 08/23/2023] [Indexed: 09/05/2023]
Abstract
Congestive cardiac failure (CCF) is a pathophysiologic state when the heart is not able to maintain its cardiac output to meet the demand of metabolising tissues. CCF is responsible for approximately 2.9 million deaths worldwide. The heterogeneous nature of CCF draws the attention of researchers to find more enthralling and promising diagnostic and treatment options. Terminalia arjuna (Arjuna) is an evergreen, deciduous tree exhibited various astringent, anti-bacterial, and anti-microbial properties. T. arjuna is being used in various regions for anginal pain, hypertension, congestive heart failure, and dyslipidemia. Although previous in vitro studies have demonstrated the therapeutic potential of T. arjuna, the exact molecular mechanism underlying its protective effect on the heart remains unclear. In this study, a network pharmacology technique was used to explore the active ingredients, potential targets in T. arjuna for the treatment of CCF. In the framework of this study, we explored the active ingredient-target-pathway network and figured out that oleanolic acid, arjunolic acid, luteolin, kaempferol, cholesterol, ellagic acid 4-O-xylopyranoside 3,3'-dimethyl ether, and cyclohexyl (2,4-dimethyl phenyl) methanone contributed significantly to the development of CCF by affecting AKT1, MAPK14, TNF, IL6, ESR1, and HSP90AA1 genes. Molecular docking analysis further validated the activities of these compounds against potential targets. To sum up, integrated network pharmacology and docking analysis revealed that T. arjuna exerts its cardioprotective effect by acting on various signalling pathways, including the thyroid hormone, VEGF signalling pathway, AGE-RAGE signalling pathway in diabetic complications, HIF signalling pathway, sphingolipid signalling pathway, and oestrogen signalling pathways. Overall, this study provides valuable insights into the molecular mechanism of T. arjuna in CCF and highlights its potential as a promising preventive treatment for this condition.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia arjuna (Roxb. ex DC.) Wight & Arnot (Combretaceae) is one of the most frequently used medicinal trees in Indian traditional medicinal systems. It is used for the treatment of a variety of diseases including cardiovascular disorders. AIM OF THE STUDY The purpose of this review was to provide a comprehensive overview of the phytochemistry, medicinal uses, toxicity, and industrial applications of T. arjuna bark (BTA), as well as to identify gaps in research and applications of this important tree. It also aimed to analyze trends and future research paths to utilize the full potential of this tree. MATERIALS AND METHODS Extensive bibliographic research on the T. arjuna tree was carried out using scientific research engines and databases such as Google Scholar, PubMed, and Web of Science, covering all relevant English-language articles. The database "World Flora Online (WFO)" (http://www.worldfloraonline.org) was used to confirm plant taxonomy. RESULTS To date, BTA has been traditionally employed for several disorders such as snakebites, scorpion stings, gleets, earaches, dysentery, sexual disorders, and urinary tract infections along with the cardioprotective activity. About 38 phytocompounds were identified from BTA and were classified as triterpenoids, tannins, flavonoids, and glycosides. A wide range of in vitro and in vivo pharmacological effects of BTA were reported such as anti-cancer, antimicrobial, antiviral, anti-inflammatory, antioxidant, hepatoprotective, anti-allergic, anti-diabetic, and wound healing activities. The oral administration of BTA (500 mg/kg) per day did not result in any toxicity in humans. The in vivo acute and sub-acute toxicity analysis of the methanol extract of BTA and one of its major compounds, 7-methyl gallate, did not produce any adverse effects up to a dose of 1000 mg/kg. CONCLUSIONS This comprehensive review highlights various aspects of traditional knowledge, phytochemicals, and pharmacological significance of BTA. The review covered safety information on employing BTA in pharmaceutical dosage forms. Despite its long history of medicinal benefit, more studies are needed to understand the molecular mechanisms, structure-activity relationship, and potential synergistic and antagonistic effects of its phytocompounds, drug administration, drug-drug interactions, and toxicological effects.

Abstract
Myocardial infarction (MI) continues to be an important issue in healthcare systems worldwide, leading to high rates of morbidity and mortality. Despite ongoing efforts towards the development of preventive measures and treatments, addressing the challenges posed by MI remains difficult both in developed and developing countries. However, researchers recently investigated the potential cardioprotective effects of taraxerol utilizing an isoproterenol (ISO)-induced cardiotoxicity model among Sprague Dawley rats. Specifically, subcutaneous tissue injections consisting of 5.25 mg/kg or 8.5 mg/kg ISO were administered over two consecutive days as stimuli to induce cardiac injury. To investigate the possibility of preventing damage caused by ISO-induced cardiotoxicity by taraxerol treatment, five groups were formed: a normal control group (1% Tween 80), an ISO control group, an amlodipine group administered 5 mg/kg/day, and various doses of taraxerol. The study results showed that treatment significantly reduced cardiac marker enzymes. Additionally, pretreatment with taraxerol increased myocardial activity in SOD and GPx, leading to significant reductions in serum CK-MB levels along with MDA, TNF-α, and IL-6. Further histopathological analysis supported these observations, as treated animals had less cellular infiltration compared to untreated ones. These multifaceted findings suggest that oral administration of taraxerol could potentially protect hearts from ISO-caused damage by increasing endogenous antioxidant concentrations while decreasing pro-inflammatory cytokines.

Abstract
Cardiovascular diseases (CVDs) are one of the leading disorders of serious death and cause huge economic loss to patients and society. It is estimated that about 18 million people have a high death ratio due to the incidence of CVDs such as (stroke, coronary heart disease, and non-ischemic heart failure). Bioactive compounds (BACs) are healthy nutritional ingredients providing beneficial effects and nutritional value to the human body. Epidemiological studies strongly shed light on several bioactive compounds that are favorable candidates for CVDs treatment. Globally, the high risk of CVDs and related results on human body parts made them a serious scenario in all communities. In this present review, we intend to collect previously published data concerned over the years concerning green-colored foods and their BACs that aim to work in the prevention, diagnosis, and/or systematic treating CVDs. We also comprehensively discussed the oral delivery of several bioactive compounds derived from fruits and vegetables and their bioavailability and physiological effects on human health. Moreover, their important characteristics, such as anti-inflammatory, lowering blood pressure, anti-obesity, antioxidant, anti-diabetics, lipid-lowering responses, improving atherosclerosis, and cardioprotective properties, will be elaborated further. More precisely, medicinal plants' advantages and multifaceted applications have been reported in this literature to treat CVDs. To the best of our knowledge, this is our first attempt that will open a new window in the area of CVDs with the opportunity to achieve a better prognosis and effective treatment for CVDs.

Abstract
Herbal medicines were the main source of therapeutic agents in the ancestral era. Terminalia arjuna (TA) is one such medicinal plant widely known for its several medicinal properties, especially its cardiovascular properties. They have several phytochemicals, such as flavonoids, polyphenols, triterpenoids, tannins, glycosides, and several minerals, proteins, and others that are responsible for the above-mentioned medicinal properties. In this review, we have first elaborated on the various processes and their parameters for the efficient extraction of relevant phytochemicals from TA extracts. Secondly, the mechanisms behind the various medicinal properties of TA extracts are explained. We have also highlighted the role of TA extracts on the green synthesis of metallic nanoparticles, especially silver and gold nanoparticles, with an elucidation on the mechanisms behind the synthesis of nanoparticles. Finally, TA extracts-based polymeric formulations are discussed with limitations and future perspectives. We believe that this review could help researchers understand the importance of a well-known cardioprotective medicinal plant, TA, and its biomedical properties, as well as their role in green nanotechnology and various formulations explored for encapsulating them. This review will help researchers design better and greener nanomedicines as well as better formulations to improve the stability and bioavailability of TA extracts.

Abstract
The study was designed to determine the fluoride distribution after its oral exposure in drinking water and its associated impact on biochemical, antioxidant markers and histology in the liver, kidney, and heart of male Wistar rats. On 100 ppm exposure, the highest accretion of fluoride occurred in the liver followed by the kidney and heart. Fluoride exposure significantly (p˂0.05) increased the plasma levels of dehydrogenase, aminotransferases, kidney injury molecule-1 (KIM-1), and other plasma renal biomarkers but decreased the levels of total plasma proteins and albumin in a dose-dependent manner. Reduction (p˂0.05) in the activities of antioxidant enzymes viz. acetylcholinesterase, arylesterase, superoxide dismutase, catalase, glutathione peroxidase, and reductase with increased levels of protein and lipid peroxidation was recorded in the liver, kidney, and heart of fluoride-administered rats. Fluoride exposure (100 ppm) induced lipid peroxidation was highest in kidney (4.4 times) followed by liver (2.6 times) and heart (2.5 times) and as compared to their respective control. The percent rise in protein oxidation at 30% was almost equal in the kidney and liver but was 21.5% in the heart as compared to control. The histopathological alterations observed included congestion and hemorrhage along with degeneration and necrosis of parenchymal cells in hepato-renal tissues and myocardium, severity of which varied in a dose-dependent manner. Taken together, fluoride distribution in the liver, heart, and kidney after chronic fluoride intake correlated well with fluoride-induced hepatic and cardio-renal toxicity in a concentration-dependent manner. These results draw attention that chronic fluoride intake pose a significant health risk for human and animal residents of fluoride endemic areas.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia argentea Mart. & Zucc. (Combretaceae), popularly known as "capitão do campo", is native from the Brazilian cerrado, which is used in folk medicine to treat inflammatory diseases. AIM OF THE STUDY We aimed to investigate the anti-inflammatory effects, toxicity and mechanisms of action regarding the use of the hydroalcoholic extract of T. argentea bark. MATERIALS AND METHODS Toxicity was determinate in vitro using the macrophage lineage J774.1 without LPS. Cells were treated with 0.5; 2; 8; 32 and 125 μg/mL of the plant extract. Cell viability was assessed by MTT colorimetric assay. The production of nitrite and cytokines was also determined in the supernatants. A NF-κB reporter assay using RAW macrophages was employed to elucidate the impact of the plant extract on the expression of such molecule. In mice, toxicity was assessed by orally given an intermediate to high concentration of the plant extract on a single dose (1000 or 5000 mg/kg) or low and intermediate doses (300 or 1000 mg/kg) twice daily for 14 days. Blood samples were collected for biochemical analysis. The anti-inflammatory activity was assessed using the air-pouch model with or without pre-inoculation with the inflammatory stimuli LPS (0.5 μg/mL), followed by treatment with plant extract at 5, 60 or 300 mg/kg administered in the air pouch (subcutaneous injection). After 4 h, mice were euthanized and the air pouches washed with 2 mL heparinized PBS (10 IU/mL). Then, the local production in the air pouch wash of cytokines, total proteins and leukocytes was assessed. RESULTS No signals of toxicity were observed either in cells or mice. Regardless the concentration used in vitro, the extract exhibited a significant anti-inflammatory activity, as perceived by the reduction of the inflammatory cytokines IL-1β, TNF-α and IL-6 and nitrites on cell supernatants. This was concomitant with a downregulation in NF-κB and elevated levels of IL-10. In mice, similar effects were observed, especially when the plant extract was given at 300 mg/kg, inhibiting the release of IL-1β, TNF-α, IL-6 and proteins, as well as increasing the release of IL-10. CONCLUSIONS Altogether, our results demonstrated that the hydroalcoholic extract of T. argentea bark has anti-inflammatory activity without inducing toxicity in cells or living animals. This activity seems to be chiefly influenced by a downregulation in NF-κB, inflammatory cytokines and production of nitrite along with augmented concentration of IL-10.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 261:113080. [PMID: 32534117 DOI: 10.1016/j.jep.2020.113080] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 05/01/2020] [Accepted: 06/04/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Various traditional texts like Ayurveda and Materia Medica profoundly mentioned the ethnopharmacological use of Terminalia bellirica fruit for its protective effect on heart and various other vital organs. Hence the present research was focussed to scientifically prove the effect of T. bellirica in support of its traditionally claimed use as cardioprotective agent. AIM THE STUDY The aim and objective of the present study was to investigate the protective effect of T. bellirica (Roxb.) against drugs viz. Doxorubicin (DOX) and Isoproterenol (ISO) induced cardiotoxicity in wistar albino rats. MATERIAL AND METHODS Cardiotoxicity was induced using DOX (15 mg/kg, i.p.) and ISO (85 mg/kg s.c.) models. Methanolic extract of T. bellirica (METB) was subjected to rats in two different doses (low dose of 250 mg/kg p.o.; and high dose of 500 mg/kg p.o.) for the purpose of investigation of various biochemical markers present in cardiac tissue as well as in blood serum, in order to assess the improvement in drugs induced cardiotoxicity. Also, the histopathological study was carried out in terms of ultrastructural changes occurred in the myocardium during drugs induced cardiomyopathy, to ensure the proposed cardioprotective effect of METB. RESULT Biochemical investigation of cardiac tissue using METB showed significant decrease in CK-MB (creatine kinase-muscle/brain) activity and MDA (malondialdehyde) levels and increase in GSH (reduced glutathione) levels. It also increased the activity of SOD (superoxide dismutase) and CAT (catalase). In serum, METB increased the levels of oxidative stress markers like ALP (alkaline phosphatase), UA (uric acid), ALT (alanine transferase), and AST (aspartate transaminase) near to their normal values as in control group. The use of METB also decreased the levels of total cholesterol and TGs (triglycerides) in serum and significantly increased HDL (high density lipoprotein) levels. Treatment with METB also proved a considerable restoration in histopathological findings of myocardium. CONCLUSION In the present study it was concluded that T. bellirica fruit has profound potential for the treatment of drugs induced cardiotoxicity suggesting the consumption of T. bellirica for cardiac benefits during routine treatment of cardiotoxicity.

Abstract
Arjuna (Terminalia arjuna) tree has been popular in Indian traditional medicine to treat cardiovascular ailments. The tree accumulates bioactive triterpene glycosides (saponins) and aglycones (sapogenins), in a tissue-preferential manner. Oleanane triterpenes/saponins (derived from β-amyrin) with potential cardioprotective function predominantly accumulate in the bark. However, arjuna triterpene saponin pathway enzymes remain to be identified and biochemically characterized. Here, we employed a combined transcriptomics, metabolomics and biochemical approach to functionally define a suite of oxidosqualene cyclases (OSCs) that catalyzed key reactions towards triterpene scaffold diversification. De novo assembly of 131 millions Illumina NextSeq500 sequencing reads obtained from leaf and stem bark samples led to a total of 156,650 reference transcripts. Four distinct OSCs (TaOSC1-4) with 54-71 % sequence identities were identified and functionally characterized. TaOSC1, TaOSC3 and TaOSC4 were biochemically characterized as β-amyrin synthase, cycloartenol synthase and lupeol synthase, respectively. However, TaOSC2 was found to be a multifunctional OSC producing both α-amyrin and β-amyrin, but showed a preference for α-amyrin product. Both TaOSC1 and TaOSC2 produced β-amyrin, the direct precursor for oleanane triterpene/saponin biosynthesis; but, TaOSC1 transcript expressed preferentially in bark, suggesting a major role of TaOSC1 in the biosynthesis of oleanane triterpenes/saponins in bark.

Abstract
Icariin, a major component of Epimedium species, was evaluated using isoproterenol (ISO)-induced cardiotoxicity in Wistar rats. Rats were treated with icariin at the doses of 1, 5, and 10 mg kg-1 orally for 15 days. Afterward, rats were administered with ISO (85 mg kg-1, subcutaneous) on 14th and 15th day to produce cardiac injury. Sildenafil (0.7 mg kg-1, intraperitoneal) was used as a positive reference to compare the effects of icariin. ISO-treated rats showed significant changes in hemodynamic parameters. Elevated levels of cardiac troponin T, nitric oxide, and tumor necrosis factor-alpha in serum, positive expression of nuclear factor-kappa B (NF-κB) and inducible nitric oxide synthase in cardiac tissue, and a decrease in serum level of interleukin-10, manifested inflammation and associated cardiac injury. However, pretreatment with icariin and sildenafil significantly prevented the hemodynamic fall and showed improved contractile and lusitropic states. Furthermore, pretreatment groups also showed a reversal of other toxicity markers to normal. Additionally, pretreatment with icariin and sildenafil significantly increased the myocardial cyclic guanosine monophosphate (cGMP) levels. Our results thus indicated the potential role of icariin in the restoration of the ISO-induced cardiac toxicity and restored membrane integrity through modulation of cGMP and NF-κB signaling.

Dipeptidyl peptidase IV Inhibitory activity of Terminalia arjuna attributes to its cardioprotective effects in experimental diabetes: In silico, in vitro and in vivo analyses. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 57:158-165.

Abstract
BACKGROUND The marketed synthetic (Dipeptidyl peptidase-IV) DPP-IV Inhibitors are expensive antidiabetic drugs and have been reported to cause unacceptable adverse effects such as pancreatitis, angioedema, thyroid and pancreatic cancers. In this scenario research to develop novel DPP-IV Inhibitors from alternative sources is the need of the hour. HYPOTHESIS/PURPOSE Terminalia arjuna, a medicinal herb with antidiabetic and cardioprotective activities may represent a natural DPP-IV Inhibitor, the DPP-IV Inhibitory activity of which may translate into demonstrable therapeutic benefits in setting of diabetes with cardiovascular co-morbidities. STUDY DESIGN The study type used for the present study was an experimental (In vitro, In vivo and In silico) design. METHOD The DPP-IV Inhibitory, antidiabetic and cardioprotective effects of Terminalia arjuna was evaluated in the experimental model of myocardial infarction co-existing with diabetes. To determine the active principle of Terminalia arjuna responsible for DPP-IV Inhibitory activity, the crystal structure of DPP-IV was considered as receptor which was docked against Arjunetin, Arjungenin, Arjunic acid, Arjunone, Ellagic acid, Gallic acid, Sitagliptin and Vildagliptin. The binding sites as well as affinity of various active ingredients of Terminalia arjuna for DPP- IV enzyme was elucidated using in silico studies and compared to Vildagliptin. RESULTS Terminalia arjuna demonstrated significant DPP-IV Inhibitory, antidiabetic (significant reduction in HbA1C) and cardioprotective effects (restoration of myocardial CPK-MB) in the experimental model of myocardial infarction co-existing with diabetes. The cardioprotective efficacy correlated to its DPP-IV Inhibitory activity. The active ingredients of Terminalia arjuna (Arjunetin, Arjungenin, Arjunic Acid Arjunone, Ellagic acid and Gallic acid) demonstrated significant inhibition of DPP-IV enzyme. Arjunic acid and Arjunone prefers the active site pocket of DPP-IV enzyme. Compounds like Arjunetin and Vildagliptin prefers to bind near the interface region of the DPP-IV as their biological active forms are homodimer. Sitagliptin binds near the α/β hydrolase domain. CONCLUSION The DPP-IV Inhibitory activity of Terminalia arjuna was found to be comparable to Vildagliptin. The DPP-IV Inhibitory activity translated into significant cardioprotective effects in the setting of diabetes. The active ingredient of Terminalia arjuna; Arjunetin, Arjungenin, Ellagic acid and Arjunic acid showed superior DPP-IV Inhibitory activity as compared to synthetic DPP-IV inhibitors (Sitagliptin and Vildagliptin) based on results of docking studies.

Abstract
Dilated cardiomyopathy (DCM) is the most common form of non-ischemic cardiomyopathy. It is characterized by ventricular chamber dilation, and myocyte hypertrophy. Human tumorous imaginal disc 1 (Tid1), a chaperone protein and response to regulate number of signaling molecules in the mitochondria or cytosol. Tid1 also plays a major role in preventing DCM; however, the role of Tid1 in isoproterenol (ISO)-induced cardiac apoptosis and hypertrophy remains unclear. H9c2 cells were pretreated Tid1 before ISO-induced hypertrophy and apoptosis and then evaluated by IHC, TUNEL assay, IFC, Co-IP, and Western blot. From the IHC experiment, we found that Tid1 proteins were increased in tissues from different stages of human myocardial infarction. Using H9c2 cardiomyoblast cells we found that Tid1 was decreased by ISO treatment. However, over-expression of Tid1S suppressed NFATc3, BNP and calcineurin protein expression and inhibited NFATc3 nuclear translocation in ISO induced cardiomyoblast cells. On the other hand, Tid1S over-expression activated survival proteins p-AKTser473 and decreased caspase-3 and cytochrome c expression. We also found that overexpression of Tid1 enhanced CHIP expression, and induced CHIP to ubiquitinate Gαs, resulting in increased Gαs degradation. Our study showed that Gαs is a novel substrate of CHIP, and we also found that the Tid1-CHIP complex plays an essential role in inhibiting ISO induced cardiomyoblast hypertrophy and apoptosis.

Abstract
Background Arjunarishta (AA), a formulation used as cardiotonic is a hydroalcoholic formulation of Terminalia arjuna (Roxb.) Wight and Arn. (TA) belonging to family Combretaceae. Objective To evaluate the anti-hyperglycemic and anti-hyperlipidemic effect of Arjunarishta on high-fat diet fed animals. Materials and methods High-fat diet fed (HFD) Wistar rats were randomly divided into three groups and treated with phytochemically standardized Arjunarishta (1.8 ml/kg), and hydroalcoholic extract of T. arjuna (TAHA) (250 mg/kg) and rosuvastatin (10 mg/kg), for 3 months. Intraperitoneal glucose tolerance test, blood biochemistry, liver triglyceride and systolic blood pressure were performed in all the groups. Effect of these drugs on the expression of tumor necrosis factor-α (TNF-α) and insulin receptor substrate-1 (IRS-1) and peroxisome proliferators activated receptor γ coactivator 1-α (PGC-1α) were studied in liver tissue using Quantitative Real-time PCR. Results HFD increased fasting blood glucose, liver triglyceride, systolic blood pressure and gene expression of TNF-α, IRS-1 and PGC-1α. Treatment of AA and TAHA significantly reduced fasting blood glucose, systolic blood pressure, total cholesterol and triglyceride levels. These treatments significantly decreased gene expression of TNF-α (2.4, 2.2 and 2.6 fold change); increased IRS-1 (2.8, 2.9 and 2.8 fold change) and PGC-1α (2.9, 3.7 and 3.3 fold change) as compared to untreated HFD. Conclusion Anti-hyperglycemic, anti-hyperlipidemic effect of Arjunarishta may be mediated by decreased TNF-α and increased PGC-1α and IRS-1.

Abstract
AIMS Cardiovascular disease is the leading cause of death with high morbidity and mortality, and chronic heart failure is the terminal phase of it. This study aimed to investigate the protective effects of the low-dose rosuvastatin on isoproterenol-induced chronic heart failure and to explore the possible related mechanisms. METHODS Male Sprague Dawley rats were given isoproterenol 5 mg/kg once a day for 7 days to establish heart failure model by subcutaneous injection. Simultaneously, low-dose rosuvastatin (5 mg/kg) was orally administrated from day 1 to day 14. Protective effects were evaluated by hemodynamic parameter, histopathological variables, serum asymmetric dimethylarginine (ADMA), cardiac troponin I (cTnI), brain natriuretic peptide (BNP) and myocardial nitric oxide (NO), and the levels of dimethylarginine dimethylaminohydrolase 2 (DDAH2), arginine methyltransferases 1 (PRMT1) and endothelial nitric oxide synthase (eNOS) expression were analyzed. RESULTS Therapeutic rosuvastatin (5 mg/kg) significantly attenuated isoproterenol-induced hypertrophy, remodeling and dysfunction of ventricle, reduced the increased serum content of ADMA, cTnI, and BNP, and elevated myocardial NO in rats (P<.05). Besides, rosuvastatin also significantly inhibited fibrosis of myocardium, normalized the increased PRMT1 and decreased DDAH2 expression. CONCLUSIONS Low-dose rosuvastatin exerted cardioprotective effects on isoproterenol-induced heart failure in rats by modulating DDAH-ADMA-NO pathway, and it may present the new therapeutic value in ameliorating chronic heart failure.

Proteomic analysis of the protective effects of aqueous bark extract of Terminalia arjuna (Roxb.) on isoproterenol-induced cardiac hypertrophy in rats. JOURNAL OF ETHNOPHARMACOLOGY 2017; 198:98-108. [PMID: 28063919 DOI: 10.1016/j.jep.2016.12.050] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2016] [Revised: 12/12/2016] [Accepted: 12/31/2016] [Indexed: 06/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aqueous bark extract of Terminalia arjuna (TA) has been in use as an ethnomedicine for cardiovascular ailments in the Indian subcontinent for centuries. Studies using hemodynamic, ROS scavenging and anti-inflammatory parameters in animal models have shown its anti-atherogenic, hypotensive, inotropic, anti-inflammatory effects. However, details analysis on its effects on established molecular and cell biological markers are a prerequisite for its wider acceptance to the medical community. AIMS OF THE STUDY To test the efficacy of TA extract in ameliorating cardiac hypertrophy induced by ISO in rats. METHODS Cardiac hypertrophy was induced by ISO (5mg/kg/day s.c. for 14 days) in rats and a standardized aqueous extract of TA stem bark was orally administered by gavage. Total RNA and protein were isolated from control, ISO, ISO plus TA and TA treated rat hearts and analyzed for the transcripts for the markers of hypertrophy, signaling kinases, transcription factors and total protein profile. RESULTS TA extract reversed the induction of fetal genes like β-myosin heavy chain, skeletal α-actin and brain natriuretic peptide in hypertrophic rat hearts. While ISO slightly increased the level of phospho-ERK, TA repressed it to about one third of the base line level. Survival kinase Akt, ER stress marker Grp78 and epigenetic regulator HDAC5 were augmented by ISO and TA restored them by various extents. ISO administration moderately increased the transcription factor NFκB binding activity, while coadministration of TA further increased it. AP-1 binding activity was largely unchanged by ISO treatment but it was upregulated when administered along with TA. MEF2D binding activity was increased by ISO and TA restored it to the baseline level. Global proteomic analysis revealed that TA treatment restored a subset of proteins up- and down-regulated in the hypertrophied hearts. Amongst those restored by TA were purinergic receptor X, myosin light chain 3, tropomyosin, and kininogen; suggesting a nodal role of TA in modulating cardiac function. CONCLUSIONS This study for the first time reveals that TA partially or completely restores the marker mRNAs, signaling kinases, transcription factors and total protein profile in rat heart, thereby demonstrating its efficacy in preventing ISO-induced cardiac hypertrophy.

Abstract
The present study evaluated the cardioprotective effects of Terminalia arjuna on classical and immuno-inflammatory markers in coronary artery disease (CAD) as an adjuvant therapy. One hundred sixteen patients with stable CAD were administered placebo/T. arjuna (500 mg twice a day) along with medications in a randomized, double-blind clinical trial. To understand the specificity and efficacy of T. arjuna, we evaluated its effect through microarray and in silico analysis in few representative samples. Data was further validated via real-time PCR (n = 50) each at baseline, 3 months, and 6 months, respectively. rIL-18 cytokine was used to induce inflammation in vitro to compare its effects with atorvastatin. T. arjuna significantly down-regulated TG, VLDL-C, and immuno-inflammatory markers in stable CAD versus placebo-treated subjects. Microarray and pathway analysis of a few samples from T. arjuna/placebo-treated groups and real-time PCR validation further confirmed our observations. Our data demonstrate the anti-inflammatory and immunomodulatory effects of T. arjuna that may attenuate ongoing inflammation and immune imbalance in medicated CAD subjects.

Abstract
Terminalia arjuna, commonly known as arjuna, belongs to the family of Combretaceae. Its bark decoction is being used in the Indian subcontinent for anginal pain, hypertension, congestive heart failure, and dyslipidemia, based on the observations of ancient physicians for centuries. The utility of arjuna in various cardiovascular diseases needs to be studied further. Therefore, the present review is an effort to give a detailed survey of the literature summarizing the experimental and clinical studies pertinent to arjuna in cardiovascular disorders, which were particularly performed during the last decade. Systematic reviews, meta-analyses, and clinical studies of arjuna were retrieved through the use of PubMed, Google Scholar, and Cochrane databases. Most of the studies, both experimental and clinical, have suggested that the crude drug possesses anti-ischemic, antioxidant, hypolipidemic, and antiatherogenic activities. Its useful phytoconstituents are: Triterpenoids, β-sitosterol, flavonoids, and glycosides. Triterpenoids and flavonoids are considered to be responsible for its beneficial antioxidant cardiovascular properties. The drug has shown promising effect on ischemic cardiomyopathy. So far, no serious side effects have been reported with arjuna therapy. However, its long-term safety still remains to be elucidated. Though it has been found quite useful in angina pectoris, mild hypertension, and dyslipidemia, its exact role in primary/secondary coronary prevention is yet to be explored.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia arjuna (Roxb.) Wight & Arn. is one of the most popular and beneficial medicinal plants in indigenous system of medicine for the treatment of cardiovascular diseases. This comprehensive review provides latest updates on traditional use, phytochemistry, pharmacological and toxicological data, clinical efficacy and safety of Terminalia arjuna as well as outlined strategies for future research and development to scientifically validate the therapeutic potential of this plant. MATERIALS AND METHODS Information about Terminalia arjuna was collected via a systematic electronic and library search of various indexed and non-indexed journals, some local books and varied articles published on ethnopharmacology, phytochemistry and traditional uses. Various pre-clinical (2000-2014) and clinical studies (1990-2014) have also been considered regarding efficacy and safety profile of Terminalia arjuna. RESULTS Evidence from various in vitro, in vivo and clinical trials reveal the pleiotropic effects of Terminalia arjuna such as anti-atherogenic, hypotensive, inotropic, anti-inflammatory, anti-thrombotic and antioxidant actions for treatment of various cardiovascular disorders. It is clearly documented that this plant has a good safety profile when used in conjunction with other conventional drugs. However, there is a paucity of data regarding the exact molecular mechanism of its action, appropriate form of drug administration, whether whole crude drug or aqueous or alcoholic extract should be used, toxicological studies and its interaction with other drugs. CONCLUSIONS In conclusion, this review highlights the importance as well as pleiotropic actions and functional aspects of Terminalia arjuna especially in cardiovascular diseases. Though, various pharmacological studies and clinical trials support its benefit in the CVD as per traditional use, new clinical trials using more rigorous state of the art technology and in a larger population setup are warranted to assess the traditional putative efficacy of Terminalia arjuna.

Abstract
Cardiorenal syndrome (CRS) is a complex disease in which the heart and kidney are simultaneously affected and their deleterious declining functions are reinforced in a feedback cycle, with an accelerated progression. Although the coexistence of kidney and heart failure in the same individual carries an extremely bad prognosis, the exact cause of deterioration and the pathophysiological mechanisms underlying the initiation and maintenance of the interaction are complex, multifactorial in nature, and poorly understood. Current therapy includes diuretics, natriuretic hormones, aquaretics (arginine vasopressin antagonists), vasodilators, and inotropes. However, large numbers of patients still develop intractable disease. Moreover, the development of resistance to many standard therapies, such as diuretics and inotropes, has led to an increasing movement toward utilization and development of novel therapies. Herbal and traditional natural medicines may complement or provide an alternative to prevent or delay the progression of CRS. This review provides an analysis of the possible mechanisms and the therapeutic potential of phytotherapeutic medicines for the amelioration of the progression of CRS.

Abstract
The present study was designed to examine the therapeutic potential of Terminalia arjuna bark extract in improving cardiovascular autonomic neuropathy in Streptozotocin (STZ)-induced diabetic Wistar Albino rats. The baroreflex was evaluated by measuring the changes in heart rate with changes in arterial blood pressure induced by bolus injections of phenylephrine (vasoconstrictor) and sodium nitroprusside (vasodilator). T. arjuna bark extract, Rosuvastatin and Insulin were tested/administered therapeutically in rat model of uncontrolled diabetes. After 8 weeks of STZ administration, the reflex bradycardia and tachycardia response to hypertension and hypotension, respectively, were impaired in the diabetic group. The reflex bradycardia improved significantly after 1 month treatment of T. arjuna while the reflex tachycardia could not improve. The decreased body weight, heart rate, blood pressure and raised blood sugar in diabetic rats were not improved by T. arjuna therapy. Rosuvastatin treatment exerted similar effects while Insulin improved all the parameters. Further T. arjuna, Rosuvastatin and Insulin significantly reduced oxidative stress and inflammatory cytokine levels in diabetic rats. Results suggest that T. arjuna bark extract improves the altered baroreflex sensitivity in diabetic rats possibly through maintaining endogenous antioxidant enzyme activities and decreasing cytokine levels.

Elevation of carbohydrate antigen 125 in chronic heart failure may be caused by mechanical extension of mesothelial cells from serous cavity effusion. Clin Biochem 2013; 46:1694-700. [PMID: 24060730 DOI: 10.1016/j.clinbiochem.2013.09.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2013] [Revised: 09/12/2013] [Accepted: 09/13/2013] [Indexed: 12/21/2022]
Abstract
OBJECTIVES The practical application of elevated carbohydrate antigen 125 (CA125) to predict clinical outcome in chronic heart failure (CHF) is under debate. The mechanism for this CA125 elevation remains unknown. We hypothesize that mechanical stress on mesothelial cells initiates CA125 synthesis. DESIGN AND METHODS A total of 191 patients suffering from edema and/or dyspnea were enrolled. 109 patients were diagnosed as CHF, and 82 patients without CHF were assigned as control group. Echocardiography, CA125, N-terminal pro-brain natriuretic peptide (NT-proBNP), and other biochemical parameters were measured. All enrolled patients underwent heart function classification. RESULTS Patients with serous cavity effusion (SCE) demonstrated higher serum CA125 than patients without SCE (82.91 (61.90-103.92) vs. 44.98 (29.66-60.30) U/mL, P<0.001). In the absence of SCE, CA125 levels in CHF patients were slightly higher than non-CHF patients (52.37 (34.85-69.90) vs. 35.15 (23.81-46.49) U/mL, P=0.017). Additionally, compared with non-CHF patients, CHF patients had higher levels of high-sensitivity C-reactive protein (hsCRP) and lower superoxide dismutase (SOD). In all enrolled patients, CA125 levels were negatively correlated with SOD concentrations (r=-0.567, P<0.001), and positively correlated with hsCRP levels (r=0.608, P<0.001). Receiver operating characteristic curve analysis showed that CA125 was better in predicting SCE than NT-proBNP, while NT-proBNP was more suitable for predicting CHF than CA125. The in vitro study demonstrated that MUC16, the CA125 coding gene, was up-regulated by mechanical stretch on human mesothelial cell line (MeT-5A). CONCLUSIONS CA125 elevation in CHF was associated with SCE. Mechanical extension of mesothelial cells from SCE plays an important role in CA125 increase.

Abstract
Vascular complications are a leading cause of mortality and morbidity in diabetic patients. Herbal drugs are increasingly being used in the treatment of cardiovascular disorders. The present study was designed to examine the therapeutic potential of Terminalia arjuna bark extract in improving myocardial function in streptozotocin (STZ)-induced diabetic rats. After 8 weeks of STZ administration, rats showed a decline in left ventricular pressure (LVP), maximal rate of rise and fall in LVP (LV [dP/dt] max and LV [dP/dt] min), cardiac contractility index (LV [dP/dt] max/LVP), and rise in LV end-diastolic pressure. Altered lipid profile, oxidative stress, and increased levels of endothelin 1 (ET-1), tumor necrosis factor-α (TNF-α), and interleukin 6 (IL-6) along with histological changes in heart and pancreas were observed in diabetic rats. T arjuna significantly attenuated cardiac dysfunction and myocardial injury in diabetic rats. It also reduced oxidative stress, ET-1, and inflammatory cytokine levels. The decreased body weight, heart rate blood pressure, and raised blood sugar in diabetic rats did not improve after T arjuna therapy. Results suggest that T arjuna bark extract improves the altered myocardial function in diabetic rats possibly through maintaining endogenous antioxidant enzyme activities, decreasing ET-1 and cytokine levels.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia arjuna - stem bark extract is traditionally used as cardiotonic in Ayurvedic medicine. AIM OF THE STUDY The present study was aimed to evaluate the molecular basis for cardioprotective potential of Terminalia arjuna (TA) stem bark, using cell cultures of human monocytic (THP-1) and human aortic endothelial cells (HAECs). MATERIALS AND METHODS Inhibitory effect of alcoholic (TAAE) and aqueous (TAWE) extracts of TA-stem bark was assessed on human 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, lipoprotein lipase (LpL) and lipid peroxidation in rat (wistar) liver and heart homogenates. The patterns of H2O2 induced reactive oxygen species (ROS) generation were observed by confocal microscopy. The activities of antioxidant enzymes and reducing power of the cells were measured in a microplate reader. Gene transcripts of proinflammatory markers in THP-1 and HAECs were assayed by real time PCR and levels of inflammatory protein markers by ELISA or flow cytometry. Phytochemical analyses of TAAE and TAWE were done using liquid chromatography, coupled to mass spectrometry (LC-MS). RESULTS TAAE and TAWE inhibited the lipid peroxidation and HMG-CoA reductase but had no effect on LpL. Both the extracts attenuated H2O2 mediated ROS generation in THP-1 cells by promoting catalase (CAT), glutathione peroxidase (GPx) activities, and by sustaining cellular reducing power. TAAE was highly effective in attenuating proinflammatory gene transcripts in THP-1 cells and HAECs, whereas the response to TAWE depended on the type of transcript and cell type. Both extracts decreased the levels of typical inflammatory marker proteins, viz. LPS induced tumor necrosis factor (TNF)-α secreted by THP-1 cells and TNF-α induced cell surface adhesion molecules on HAECs, namely vascular cell adhesion molecule-1 (VCAM-1) and E-selectin. Phytochemical analyses indicated the richness in phenolic compounds and terpenes of TAAE and TAWE, while revealing variability in their metabolite profile. CONCLUSION Our study scientifically validates the antioxidative and antiinflammatory properties of Terminalia arjuna stem bark. The marked effects on cultured human monocytic and aortic endothelial cells (HAEC) provide the biochemical and molecular basis for therapeutic potential of TA-stem bark against cardiovascular diseases (CVD).

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia pallida is an evergreen endemic tree, mentioned in Ayurveda as the fruits of Terminalia pallida are excellent in cardioprotective property. Tribal people use Terminalia pallida fruit for the treatment of diabetes and this plant widely used in many other disorders. AIM OF STUDY The present investigation was to evaluate the antioxidant, biochemical profile and histological studies of qualitatively standardized ethanolic extract of Terminalia pallida fruits (TpFE) against isoproterenol-induced myocardial infarction in rats. MATERIALS AND METHODS TpFE was standardized by high performance liquid chromatography (HPLC) and mass spectroscopy (MS). Rats were pretreated orally with different doses of TpFE (100, 300, and 500mgkg(-1) body weight) and cardioprotective positive control gallic acid (GA) for 30 days prior to isoproterenol (ISO) induced myocardial infarction. The rats were sacrificed, hearts were collected and homogenized for biochemical analysis. The effects on total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C), high density lipoprotein cholesterol (HDL-C), lipid peroxidation (LPO) marker, malondialdehyde (MDA), creatine kinase (CK), lactate dehydrogenase (LDH), alanine transaminase (ALT), aspartate transaminase (AST), catalase (CAT), glutathione peroxidase (GPx), sodium potassium (Na(+)/K(+)), calcium (Ca(2+)) and magnesium (Mg(2+)) adenosine triphosphatases (ATPases) were estimated in heart tissue homogenate. RESULTS Rats administered with ISO showed a significant increase in TC, TG, LDL-C, VLDL-C, and MDA and a significant decrease in HDL-C, cardiac marker enzymes - CK, LDH, ALT and AST. ISO significantly reduced antioxidants - CAT, GPx, and membrane bound enzymes - Na(+)/K(+), Ca(2+) and Mg(2+) ATPases. Pretreatment with TpFE (100, 300, and 500mgkg(-1) bw) and GA (15mgkg(-1) bw) for a period of 30 days significantly inhibited the effects of ISO. Moreover, biochemical findings were supported by histopathological observations. CONCLUSION The present study provide evidence for the first time, that TpFE pretreatment ameliorated myocardial injury in ISO-induced myocardial infarcted rats and exhibited cardioprotective activity.
