Abstract
The incidence and prevalence of cardiovascular diseases are still rising. The principal mechanism that drives them is atherosclerosis, an affection given by dyslipidemia and a pro-inflammatory state. Paraoxonase enzymes have a protective role due to their ability to contribute to antioxidant and anti-inflammatory pathways, especially paraoxonase 1 (PON1). PON1 binds with HDL (high-density lipoprotein), and high serum levels lead to a protective state against dyslipidemia, cardiovascular diseases, diabetes, stroke, nonalcoholic fatty liver disease, and many others. Modulating PON1 expression might be a treatment objective with significant results in limiting the prevalence of atherosclerosis. Lifestyle including diet and exercise can raise its levels, and some beneficial plants have been found to influence PON1 levels; therefore, more studies on herbal components are needed. Our purpose is to highlight the principal roles of Praoxonase 1, its implications in dyslipidemia, cardiovascular diseases, stroke, and other diseases, and to emphasize plants that can modulate PON1 expression, targeting the potential of some flavonoids that could be introduced as supplements in our diet and to validate the hypothesis that flavonoids have any effects regarding PON1 function.

ACS OMEGA 2023; 8:42548-42554. [PMID: 38024697 PMCID: PMC10652819 DOI: 10.1021/acsomega.3c05282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2023] [Revised: 10/04/2023] [Accepted: 10/12/2023] [Indexed: 12/01/2023]
Abstract
Gastric problems are often caused by the well-known Helicobacter pylori (H. pylori) bacterium. One of the biggest obstacles to the treatment of H. pylori infections is increasing the antibiotic resistance. During our search for naturally derived anti-H. pylori compounds, six major compounds were isolated from the methylene chloride (CH2Cl2) and ethyl acetate (EtOAc) fractions of Rumex acetosa that showed anti-H. pylori activity. Three anthraquinones and three anthraquinone glucosides were identified as the major chemical constituents of the CH2Cl2 and EtOAc fractions, respectively. The chemical structures were identified to be emodin (1), chrysophanol (2), physcion (3), emodin-8-O-β-d-glucoside (4), chrysophanol-8-O-β-d-glucoside (5), and physcion-8-O-β-d-glucoside (6) by UV, 1H NMR, 13C NMR, and mass spectrometry. Anti-H. pylori activity, including the minimum inhibitory concentration (MIC) value of each compound, was evaluated against two H. pylori strains. All isolates exhibited anti-H. pylori activity with different potencies, with an MIC value ranging between 3.13 and 25 μM. However, some variations were found between the two strains. While compound 5 displayed the most potent antibacterial activity with an MIC50 value of 8.60 μM and an MIC90 value of 15.7 μM against H. pylori strain 51, compound 1 exhibited the most potent inhibitory activity against H. pylori strain 43504. The two compounds also showed moderate urease inhibitory activity, with compound 1 demonstrating activity higher than that of compound 5. Furthermore, a molecular docking study revealed the high binding ability of compounds 1 and 5 to the active site of H. pylori urease. The present study suggests that the six anthraquinones isolated from R. acetosa with the whole parts of this plant may be natural candidates for the treatment of H. pylori infection. Further studies are required to determine the exact mechanism of action and to evaluate safety issues in the human body.

Ahmad M, Ahmad T, Irfan HM, Noor N. Blood pressure-lowering and cardiovascular effects of plumbagin in rats: An insight into the underlying mechanisms. CURRENT RESEARCH IN PHARMACOLOGY AND DRUG DISCOVERY 2022; 3:100139. [PMID: 36568266 PMCID: PMC9780077 DOI: 10.1016/j.crphar.2022.100139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 10/17/2022] [Accepted: 11/15/2022] [Indexed: 11/20/2022] Open
Abstract
Background Plumbagin, a natural phenolic compound is investigated for response against blood pressure and vascular reactivity. Methodology Blood pressure lowering effects were observed by in-vivo invasive evaluation in normotensive rats, and in-vitro experimentation to measure changes of tension in isolated rat aorta and contractility in atria. Results The percentage decrease in mean arterial pressure (MAP) observed with plumbagin intravenously at doses of 0.1, 0.5, 1, 5, 10 μg/kg in normotensive rats was 7.16 ± 2.35, 15.5 ± 5.62, 19.5 ± 5.27, 26 ± 6.67, 34.33 ± 8.80, respectively. Plumbagin exerted vasorelaxant effects in rat aorta, unaffected by the removal of vascular endothelium, and L-NAME and methylene blue pretreatment. Plumbagin completely inhibited phenylephrine (1 μM) and High K+ (80 mM) induced contractions. Similar to a Ca+2 channel antagonist, plumbagin caused a rightward shift in the Ca+2 concentration-response-curves (CRCs), resembling nifedipine. Pre-incubation with plumbagin, significantly suppressed contractions induced by phenylephrine in Ca+2-free medium via disrupting Ca+2 release from intracellular stores. No change in vasorelaxant response was observed with the addition of potassium channel blockers, TEA and BaCl2. In rat atrial strips, plumbagin exerted significant negative inotropic and chronotropic effects. No significant change was observed with atropine and atenolol pretreatment, so the effect appeared independent of muscarinic and beta-adrenergic receptors. Conclusion This study suggests the blood pressure lowering effects of plumbagin. That could be contributed by a decrease in vascular resistance via calcium antagonism, interferences in calcium efflux, and depressive effects on the rate and force of cardiac contraction. Further studies would be necessary to probe deeper into the underlying mechanisms.

Abstract
The study evaluated prebiotic potential and the enzyme inhibition of extracts and isolated compounds of Rumex vesicarius (ruby dock), family Polygonaceae. Eight known compounds were identified in the roots of R. vesicarius. Extracts and compounds (1-8) increased the growth rate of Escherichia coli Nissle 1917 differentially compared to controls. The highest prebiotic index (PI) and activity score was recorded for EcN in the presence of compound 4, followed by, in descending order, petroleum ether, ethyl acetate, and total methanol extracts. The compounds and extracts reduced protease, α-amylase, and angiotensin-converting enzyme activities. This inhibitory activity was positively correlated with PI, Pscore, µu, and Ymax. These findings suggest that R. vesicarius is a good source of potential prebiotic and can boost beneficial bacteria. It may also be considered promising for treatment of diabetes mellitus, controlling weight, and regulating blood pressure.

Abstract
Rumex L., a genus in Polygonaceae family with about 200 species, is growing widely around the world. Some Rumex species, called "sorrel" or "dock", have been used as food application and treatment of skin diseases and hemostasis after trauma by the local people of its growing areas for centuries. To date, 29 Rumex species have been studied to contain about 268 substances, including anthraquinones, flavonoids, naphthalenes, stilbenes, diterpene alkaloids, terpenes, lignans, and tannins. Crude extract of Rumex spp. and the pure isolates displayed various bioactivities, such as antibacterial, anti-inflammatory, antitumor, antioxidant, cardiovascular protection and antiaging activities. Rumex species have important potential to become a clinical medicinal source in future. This review covers research articles from 1900 to 2022, fetched from SciFinder, Web of Science, ResearchGate, CNKI and Google Scholar, using "Rumex" as a search term ("all fields") with no specific time frame set for the search. Thirty-five Rumex species were selected and summarized on their geographical distribution, edible parts, traditional uses, chemical research and pharmacological properties.

Abstract
Objective This study determines the efficacy and probable underlying mode of action to the folk usage of Euphorbia hirta, Fagonia indica and Capparis decidua in hypertension. Methods The aqueous-methanol extracts of E. hirta (EH.Cr), F. indica (FI.Cr) and C. decidua (CD.Cr) were tested for antihypertensive effects in rats using non-invasive and in-vasive blood pressure measuring apparatus. In-vitro assays were carried out using isolated rat aortae using PowerLab station. Results EH.Cr, FI.Cr and CD.Cr at 500 mg/kg (orally) caused a fall in the mean systolic blood pressure in arsenic-induced hypertensive and normotensive rats, similar to nifedipine. In rat aortae, EH.Cr, CD.Cr and FI.Cr reversed low (20 mM), high (80 mM) K+ and phenylephrine (P.E)-driven contractions, while F. indica partially inhibited high K+ contractions. In the presence of TEA, F. indica remained unable to relax low K+ contractions. EH.Cr and CD.Cr moved Ca++ concentrations response curves to the right, like nifedipine. All fractions of EH.Cr and CD.Cr except aqueous, pet-ether and chloroform fractions of FI.Cr displayed Ca++ antagonistic activity. FI.Cr, its ethyl acetate and aqueous fraction exhibited TEA-sensitive potassium channel activation. On baseline tension, test materials also produced phentolamine-sensitive vasospasm. Conclusion E. hirta, F. indica and C. decidua possess antihypertensive activity in arsenic-induced hypertensive rats possibly mediated via endothelium-dependent vasorelaxation. In normotensive rats, E. hirta and C. decidua showed antihypertensive activities through endothelium-dependent and Ca++ antagonistic pathways, while F. indica exhibited potassium channel activation and Ca++ antagonistic like effects in its vasorelaxation. Additional weaker vasospastic effects were derived through α-adrenergic like pathways.

Abstract
Pulmonary arterial hypertension (PAH) is a type of high morbidity and mortality disease. Currently, the intrinsic metabolic alteration and potential mechanism of PAH are still not fully uncovered. Previously, we have found that polyphenol resveratrol (Rev) reversed the remodeling of the pulmonary vasculature and decreased the number of mitochondria in pulmonary arterial smooth muscle cells (PASMCs) (Lei Yu et al. (2017)). However, potential effects of Rev on the changed metabolic molecules derived from lung tissue and serum have no fully elucidated. Thus, we conducted a systematic elaboration through the metabonomics method. Various of metabolites in different pathways including amino acid metabolism, tricarboxylic acid cycle (TCA), acetylcholine metabolism, fatty acid metabolism and biosynthesis in male Wistar rats' sera and lung tissues were explored in three groups (normal group, PAH group, PAH and Rev treatment group). We found that leucine and isoleucine degradation, valine, leucine and isoleucine biosynthesis, tryptophan metabolism and aminoacyl-tRNA biosynthesis were involved in the development of PAH. Hydroxyphenyllactic, isopalmitic acid and cytosine might be significant key metabolites. Further work in this area may inform personalized treatment approaches in clinical practice of PAH through elucidating pathophysiology mechanisms of experimental verification.

Abstract
Background: Juglone, a natural phenolic compound obtained from the walnut tree, is known for its wide range of biological activities. However, it has yet to be tested for its effects on hypertension and vascular tone. This investigation was aimed to explore the antihypertensive effect and the nature of vascular reactivity of juglone in rat models.Methods: Juglone was tested in in vivo and in vitro experiments in rats. The responses were analyzed and recorded through a PowerLab data acquisition system.Results: Intravenous injection of juglone significantly decreased the mean arterial blood pressure (MAP) in normotensive and hypertensive rats (Max. fall, 43.50 ± 2.96 vs 49.66 ± 3.28 mmHg). In rats pretreated with Nω-Nitro l-arginine methyl ester (L-NAME), the effect of juglone on MAP was reduced as compared to the control. However, in rats pretreated with atropine the fall in MAP by juglone was not altered. Juglone induced relaxation in the phenylephrine, K+ (80 mM), and angiotensin II pretreated isolated rat aortic rings. This vasorelaxant effect was reduced with L-NAME pretreatment. Atropine pretreatment did not modify the vasorelaxant effect of juglone. Pre-incubation with juglone attenuated the intracellular Ca2+ release by suppressing phenylephrine peak formation and also shifted CaCl2 concentration-response curves (CRCs) to the right. Of note, combined treatment with 4-aminopyridine and barium chloride also reduced juglone-mediated vasorelaxation suggesting a role of K+-channels as well.Conclusion: In conclusion, juglone exerts its antihypertensive effect through vasorelaxation, which is mediated by nitric oxide, inhibition of intracellular calcium release and opening of K+-channels.

Abstract
Background The Rumex acetosa has been used in medicinal treatment, food technology and phytotherapeutics in Eastern Asia and many other countries. However, its effect on cardiovascular system and antiplatelet activity remained to be known. In this study, we examined the antiplatelet activity of R. acetosa in detailed manner to understand underlying mechanism. Methods To study this, whole blood was obtained from male Sprague Dawley (SD) rats and aggregation of washed platelets measured using light transmission aggregometry. Intracellular calcium ion concentration ([Ca2+]i) was measured using Fura-2/AM while ATP release evaluated by luminometer. Activation of integrin αIIbβ3 analyzed by flow cytometry and clot retraction. Furthermore, we studied the signaling pathways mediated by R. acetosa extract by western blot analysis. Results R. acetosa extract markedly inhibited collagen-induced platelet aggregation and ATP release in a dose-dependent manner. It also suppressed [Ca2+]i mobilization, integrin αIIbβ3 activation and clot retraction. The extract significantly attenuated phosphorylation of the MAPK pathway (i.e., ERK1/2, JNK), MKK4, PI3K/Akt, and Src family kinase. Conclusion Taken together, this data suggests that R. acetosa extract exhibits anti-platelet activity via modulating MAPK, PI3K/Akt pathways, and integrin αIIbβ3-mediated inside-out and outside-in signaling, and it may protect against the development of platelet-related cardiovascular diseases.

Abstract
BACKGROUND Matricaria pubescens is a medicinal plant from North Africa. This plant is widely used in alternative medicine as a remedy against rheumatism, inflammation, diabetes and hypertension. AIM The aim of the study was to evaluate the possible antihypertensive and vasodilator activity of the aqueous extract of Matricaria pubescens (M. pubescens). MATERIAL AND METHODS In the current study, the aqueous extract of the aerial parts of M. pubescens (AEMP) was prepared and its antihypertensive activity was examined in N(ω)-nitro-L-arginine methyl ester (L-NAME)-induced hypertensive rats. RESULTS The results indicated that AEMP reduced the systolic, diastolic, mean arterial blood pressure in hypertensive rats but not in normotensive rats. The data revealed that AEMP exhibits its antihypertensive effect through vasorelaxant activity. More interestingly, this study approved that the vasorelaxant capacity of AEMP seems to be mediated through vascular cyclooxygenase pathway, the opening of K+ channels and sGC-cGMP induction pathway. CONCLUSION The study illustrates the beneficial action of M. pubescens as an antihypertensive agent.

Abstract
Gerbera piloselloides (L.) Cass. (Compositae) possesses various biological effects. It is used as an oriental remedy for relieving cough and resolving phlegm. The present study is to investigate the vasodilation effects of Gerbera piloselloides on isolated rat mesenteric arteries (MAs) and the potential mechanism. Different organic extracts of Gerbera piloselloides were tested, and an HPLC-UV-FD-based analytical method was established to identify the active constituents. The principal components, namely, 8-MOP (8-methoxypsoralan) and 8-MSD (8-methoxysmyrindiol), were found to be predominant in the extracts of petroleum ether and dichloroform, which showed stronger vasodilation activities. 8-MSD was isolated from Gerbera piloselloides by silica gel column chromatography coupled with a Waters 2545 high throughput autopurification system, and its vasodilation effects were explored by an assay of tension on rat MA rings. The results suggest that 8-MSD induces vascular relaxation in rat MAs via an endothelium-dependent mechanism involving the Kir channel, which enables Ca2+ entry in the cell and activates production of NO. The present research indicates that 8-MSD may be therapeutically useful as an anti-hypertension agent and to potentially treat cardiovascular and gastrointestinal diseases.
