JOURNAL OF ETHNOPHARMACOLOGY 2024:118902. [PMID: 39395765 DOI: 10.1016/j.jep.2024.118902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2024] [Revised: 09/03/2024] [Accepted: 10/04/2024] [Indexed: 10/14/2024]
Abstract
ETHNOPHARMACOLOGIC RELEVANCE Chuanxiong Rhizoma (CX) is the dried root rhizomes of the plant Ligusticum chuanxiong Hort. of the family Umbelliferae. CX is listed as a superior herb in the book "Shennong Bencao Jing". It has a pungent and warm nature and belongs to the liver, gallbladder, and pericardium meridians. CX is documented in the Chinese Pharmacopoeia from 1963 to 2020 editions. CX as a well-known traditional Chinese medicine for promoting blood circulation, regulating qi, dispelling wind, and relieving pain, has been proven to contain a variety of bioactive compounds with diverse pharmacological activities and medicinal value. AIM OF THE STUDY The current review aims to provide a comprehensive analysis of the botany, traditional uses, phytochemistry, pharmacology, toxicity, quality control and pharmacokinetics of CX. MATERIALS AND METHODS The relevant information of CX was obtained from several databases including Web of Science, PubMed, ACS Publications, Google Scholar, Baidu Scholar, CNKI, Ph.D, MSc dissertations, as well as The Catalogue of Life, Flora of China database, and The Global Biodiversity Information Facility. RESULTS CX is widely used in traditional medicine for treating various diseases related to the cardiovascular system, liver and kidney system, nervous system, respiratory system, and more. Over 400 compounds have been identified in CX, including phthalides, alkaloids, organic acids and its esters, polyphenols, terpenes and their derivatives, polysaccharides, hydrocarbons and their derivatives, coumarins, lignans and others. The plant extracts, compounds and Chinese patent medicines possess various pharmacological activities, including cardiovascular system protection, nervous system protection, cerebrovascular system protection, anti-inflammatory, liver and lung protection, anti-diabetes, anti-osteoporosis, anti-bacterial, anti-aging, anti-oxidant, immune regulation, prevention of DNA damage, prevention of postoperative peritoneal adhesion. CONCLUSION Considering its traditional and modern applications, phytochemical composition, and pharmacological properties, CX can be regarded as a traditional Chinese medicine resource for treating various diseases related to the cardiovascular, hepatorenal, nervous, and respiratory systems. Current research mainly focuses on cell and animal experiments, where some active ingredients exhibit diverse pharmacological activities. However, further studies are needed to fully understand its specific mechanisms of action. In addition, there are multiple active ingredients in CX, but current research mainly focuses on the pharmacological effects of individual components, with little research on the interactions and synergistic effects between different components. It is recommended to strengthen the research on the interactions of CX compounds and their components to reveal the overall pharmacological mechanisms. This will contribute to quality control, new drug development, commercialization, and promote its continuous development in the field of medicine.

Gu X, Li Z, Feng Y, Hu Y, Xie K, Shang J, Ma C, Ju W, Zou J, Xu M. A mathematical multiple-dimensional strategy for Q-markers identification based on "five principles": Tianshu Capsule for migraine treatment as an example. JOURNAL OF ETHNOPHARMACOLOGY 2024; 337:118848. [PMID: 39307208 DOI: 10.1016/j.jep.2024.118848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2024] [Revised: 08/25/2024] [Accepted: 09/19/2024] [Indexed: 09/28/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Quality control is a critical element for Traditional Chinese medicine (TCM). Due to the varied chemical components, mechanisms of action, and pharmacological functions in TCM, ensuring quality is more challenging compared to chemical drugs. Then, the concept of quality markers (Q-markers) was proposed and ideal Q-markers for TCM prescriptions need to compliant with "five principles", including pharmacological effectiveness, specificity, transfer and traceability, measurability, and prescription compatibility. AIM OF THE STUDY To establish a mathematical multiple-dimensional "spider-web" strategy and identify the Q-markers of Tianshu capsule (TSC), a Chinese patent medicine for the treatment of migraine, following the "five principles" rules. MATERIALS AND METHODS Q-marker candidates of TSC were firstly screened according to the HPLC fingerprints. Their contents in 10 batches of TSC and stabilities under high temperature, high humidity and in work solutions were determined quantitatively by HPLC-UV (measurability). Their existences in Gastrodiae Rhizoma, Chuanxiong Rhizoma, TSC, rat plasma and brain samples were investigated using HPLC-Q-TOF/MS (transfer and traceability). Their anti-migraine efficacies were evaluated by network pharmacology and mice hot-plate analgesia test; and their relationships with the property (flavor) of Gastrodiae Rhizoma or Chuanxiong Rhizoma were studied by molecular docking (effectiveness). Their contributions were defined based on their herb source according to the compatibility theories of Da Chuan Xiong Fang (compatibility). Their biosynthetic pathways were studied, and their frequencies detected in different plant families were calculated (specificity). Finally, an eight dimensional "spider-web" mode was developed for 10 components, and the regression area (RA) and the coefficient variation (CV) of each candidate were calculated after data normalization. RESULTS Ten components including gastrodin, parishin E, chlorogenic acid, ferulic acid, isochlorogenic acid A, senkyunolide I, H, A, Z-ligustilide and levistilide A were selected and evaluated as the Q-marker candidates. The results showed that gastrodin, senkyunolide I, and senkyunolide A had the higher RA and lower CV than other compounds with the established "spider-web" mode, indicating that they could be used as the Q-markers of TSC. CONCLUSION The multi-dimensional "spider-web" mode based on "five principles" was firstly applied to identify the Q-markers of TSC, and it can be used as a practical strategy to discover Q-markers of other compounded prescriptions.

JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117121. [PMID: 37660954 DOI: 10.1016/j.jep.2023.117121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 05/28/2023] [Accepted: 08/30/2023] [Indexed: 09/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Wuwei Jiangya decoction (WJD) is a traditional Chinese medicinal formula (Fangji) composed of Gastrodiae Rhizoma, Chuanxiong Rhizoma, Puerariae Lobatae Radix, Cyathulae Radix, and Achyranthis Bidentatae Radix, all of which have been verified to combat hypertension. However, the integrative "shot-gun" mechanism of WJD and its primary active ingredients are still unclear. AIM OF THE STUDY To investigate the anti-hypertensive effects of WJD and its originating ingredients. METHODS Network-based degree distribution analysis combined with in vivo experiments were performed. RESULTS A total of 144 active ingredients in WJD were identified to regulate 84 hypertension-related targets, which are mainly involved in blood pressure and blood vessel diameter regulation. However, for the anti-hypertension effects, "more does not mean better". The majority (76%) of the hubs in the H-network were regulated by no more than four ingredients. We identified 16 primary ingredients that accounted for the therapeutic action against hypertension. For compatibility, the five herbs consistently focused on blood pressure, vascular diameter, and angiogenesis, with the renin-angiotensin system as a primary target. The characteristics of each herb were involved in processes such as lipid localization and oxidative stress, which interact to constitute the regulatory network targeting hypertension, its risk factors, and organ damage. In vivo, WJD significantly reduced systolic blood pressure (SBP), improved left ventricular mass index, and ameliorated cardiac hypertrophy and vascular injury by moderating the renin-angiotensin system via activating the ACE2/Ang-(1-7)/Mas signaling pathway. CONCLUSION WJD can lower SBP and ameliorate cardiac hypertrophy and vascular injury through the ACE2/Ang-(1-7)/Mas pathway, thus providing new insights into the development of traditional Chinese medicine as a therapeutic agent for hypertension.

[PMID: 37038017 DOI: 10.1007/s10787-023-01219-8] [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: 01/30/2023] [Accepted: 03/29/2023] [Indexed: 04/12/2023]
Abstract
Simvastatin is a semisynthetic inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase and is used extensively to treat atherosclerotic cardiovascular disease. Apart from the lipid-lowering effect, simvastatin has been documented to offer impressive vasorelaxant activity. However, the mechanism associated with this vasorelaxant activity has yet not been substantially explored. Thus, the present study has aimed to elucidate the mechanism(s) associated with simvastatin-induced vasorelaxation using an established rat aortic ring model. The results from the study depicted that simvastatin caused significant relaxation in aortic rings pre-contracted with phenylephrine and potassium chloride (KCl). The vasorelaxant effect of simvastatin was attenuated by methylene blue (sGC-dependent cyclic guanosine monophosphate (cGMP) inhibitor), NG-nitro-L-arginine methyl ester (L-NAME; NO synthase inhibitor), 4-aminopyridine (Kv blocker), glibenclamide (KATP blocker), and barium chloride (Kir blocker). In addition, the vasorelaxant effect of simvastatin was slightly reduced by PD123319 (angiotensin II type 2 receptor (AT2R) antagonist). However, indomethacin (COX inhibitor), 1H-[1,2,4]Ox adiazolol [4,3-α]quinoxalin-1-one (ODQ; selective soluble guanylate cyclase (sGC) inhibitor), losartan (angiotensin II type 1 receptor (AT1R) antagonist), atropine (muscarinic receptor blocker), and tetraethyl ammonium (TEA; KCa blocker) did not affect the vasorelaxant effect of simvastatin. Furthermore, simvastatin was found to attenuate the release of calcium (Ca2+) from intracellular stores in the presence of ruthenium red (ryanodine receptor, RyR inhibitor) and extracellular stores via nifedipine (voltage-operated Ca2+ channels, VOCC blocker) and SK&F96365 (receptor-operated Ca2+ channel, ROCC blocker). Thus, it can be concluded that the vasorelaxant effect of simvastatin involves NO/cGMP pathways, AT2R receptors, Ca2+ channels, and K+ channels.

Abstract
Cardio-cerebrovascular diseases (CVDs) are a serious threat to human health and account for 31% of global mortality. Ligusticum chuanxiong Hort. (CX) is derived from umbellifer plants. Its rhizome, leaves, and fibrous roots are similar in composition but have different contents. It has been used in Japanese, Korean, and other traditional medicine for over 2000 years. Currently, it is mostly cultivated and has high safety and low side effects. Due to the lack of a systematic summary of the efficacy of CX in the treatment of CVDs, this article describes the material basis, molecular mechanism, and clinical efficacy of CX, as well as its combined application in the treatment of CVDs, and has been summarized from the perspective of safety. In particular, the pharmacological effect of CX in the treatment of CVDs is highlighted from the point of view of its mechanism, and the complex mechanism network has been determined to improve the understanding of CX's multi-link and multi-target therapeutic effects, including anti-inflammatory, antioxidant, and endothelial cells. This article offers a new and modern perspective on the impact of CX on CVDs.

Tianma Gouteng Decoction regulates oxidative stress and inflammation in AngII-induced hypertensive mice via transcription factor EB to exert anti-hypertension effect. Biomed Pharmacother 2021; 145:112383. [PMID: 34736077 DOI: 10.1016/j.biopha.2021.112383] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2021] [Revised: 10/18/2021] [Accepted: 10/25/2021] [Indexed: 01/01/2023] Open
Abstract
Hypertension is one of the important causes of cardiovascular diseases, and the imbalance of vascular homeostasis caused by oxidative stress and endothelial inflammation occurs throughout hypertension pathogenesis. Therefore, inhibiting oxidative stress and endothelial inflammation is important for treating hypertension. Tianma Gouteng Decoction (TGD) is a Chinese herbal medicine that is commonly used to treat hypertension in China, and demonstrates clinically effective antihypertensive effects. However, its blood pressure reduction mechanism remains unclear. In this study, we further determined the antihypertensive effects of TGD and revealed its underlying mechanism. We established an AngII-induced hypertension mice model, which was treated with TGD for six weeks. We monitored blood pressure, heart rate, and body weight every week. After six weeks, we detected changes in the structure and function of the heart, the structure of blood vessels, and vasomotor factors. We also detected the expression of oxidative stress and inflammation-related genes. We found that TGD can significantly reduce blood pressure, improve cardiac structure and function, and reverse vascular remodeling, which could be due to the inhibition of oxidative stress and inflammation. We also found that the effect of inhibiting oxidative stress and inflammation could be related to the up-regulation of transcription factor EB (TFEB) expression by TGD. Therefore, we used AAV9 to knock down TFEB and observe the role of TFEB in TGD's antihypertensive and cardiovascular protection properties. We found that after TFEB knockdown, the protective effect of TGD on blood pressure and cardiovascular remodeling in AngII-induced hypertensive mice was inhibited, and that it was unable to inhibit oxidative stress and inflammation. Therefore, our study demonstrated for the first time that TGD could exert anti-oxidative stress and anti-inflammatory effects through TFEB and reverse the cardiovascular remodeling caused by hypertension.

Vasorelaxant-Mediated Antihypertensive Effect of the Leaf Aqueous Extract from Stephania abyssinica (Dillon & A. Rich) Walp (Menispermaceae) in Rat. BIOMED RESEARCH INTERNATIONAL 2021; 2021:4730341. [PMID: 34660790 PMCID: PMC8519676 DOI: 10.1155/2021/4730341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 09/17/2021] [Indexed: 11/21/2022]
Abstract
Stephania abyssinica is a medicinal plant used in Cameroon alternative medicine to treat arterial hypertension (AHT). Previous in vitro studies demonstrated the endothelium nitric oxide-independent vasorelaxant property of the aqueous extract from Stephania abyssinica (AESA). But its effect on AHT is unknown. The present study was undertaken to explore other vasorelaxant mechanisms and to determine the antihypertensive effects of AESA in male Wistar rats. Phytochemical analysis of AESA was carried out using the liquid chromatography-mass spectrometry (LC-MS) method. The vasorelaxant effects of AESA (1-1000 μg/mL) were studied on rat isolated thoracic aorta rings, in the absence or presence of indomethacin (10 μM) or methylene blue (10 μM). The inhibitory effect of AESA on phenylephrine (PE, 10 μM) or KCl- (60 mM) induced contraction as well as the intracellular calcium release was also evaluated. The in vivo antihypertensive activity of AESA (43, 86, or 172 mg/kg/day) or captopril (20 mg/kg/day) administered orally was assessed in L-NAME- (40 mg/kg/day) treated rats. Blood pressure and heart rate (HR) were measured at the end of each week while serum or urinary nitric oxide (NO), creatinine, and glomerular filtration rate (GFR) were determined at the end of the 6 weeks of treatment, as well as histological analysis of the heart and the kidney. The LC-MS profiling of AESA identified 9 compounds including 7 alkaloids. AESA produced a concentration-dependent relaxation on contraction induced either by PE and KCl, which was significantly reduced in endothelium-denuded vessels, as well as in vessels pretreated with indomethacin and methylene blue. Moreover, AESA inhibited the intracellular Ca2+ release-induced contraction. In vivo, AESA reduced the AHT, heart rate (HR), and ventricular hypertrophy and increased serum NO, urine creatinine, and GFR. AESA also ameliorated heart and kidney lesions as compared to the L-NAME group. These findings supported the use of AESA as a potential antihypertensive drug.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plectranthus vettiveroides (Jacob) N.P. Singh & B.D. Sharma is a traditional medicinal plant used in Siddha System of Medicine and its aromatic root is used to reduce the elevated blood pressure. AIM The aim of the present study was to study vasorelaxant property of the root essential oil nanoemulsion (EON) of P. vettiveroides. METHODS The EON was formulated to enhance the solubility and bioavailability and characterized. The preliminary screening was performed by treating the EON with aortic rings pre-contracted with phenylephrine (1 μM) and potassium chloride (80 mM). The role of K⁺ channels in EON induced vasorelaxation was investigated by pre-incubating the aortic rings with different K⁺ channel inhibitors namely, glibenclamide (a non-specific ATP sensitive K⁺ channel blocker, 10 μM), TEA (a Ca2⁺ activated non-selective K⁺ channel blocker, 10-2 M), 4-AP (a voltage-activated K⁺ channel blocker, 10-3 M) and barium chloride (inward rectifier K⁺ channel blocker, 1 mM). The involvement of extracellular Ca2+ was performed by adding cumulative dose of extracellular calcium in the presence and absence of EON and the concentration-response curve (CRC) obtained is compared. Similarly, the role of nitric oxide synthase, muscarinic and prostacyclin receptors on EON induced vasorelaxation were evaluated by pre-incubating the aortic rings with their inhibitors and the CRC obtained in the presence and absence of inhibitor were compared. RESULTS The GC-MS and GC-FID analyses of the root essential oil revealed the presence of 62 volatile compounds. The EON exhibited significant vasorelaxant effect through nitric oxide-mediated pathway, G-protein coupled muscarinic (M3) receptor pathway, involvement of K+ channels (KATP, KIR, KCa), and blocking of the calcium influx by receptor-operated calcium channel. CONCLUSION It is concluded that the root essential oil of P. vettiveroides is possessing marked vasorelaxant property. The multiple mechanisms of action of the essential oil of P. vettiveroides make it a potential source of antihypertensive drug.

Abstract
At present, cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide, and global trends suggest that this panorama will persist or worsen in the near future. Thus, optimization of treatment strategies and the introduction of novel therapeutic alternatives for CVD represent key objectives in contemporary biomedical research. In recent years, phytotherapy-defined as the therapeutic use of whole or minimally modified plant components-has ignited large scientific interest, with a resurgence of abundant investigation on a wide array of medicinal herbs (MH) for CVD and other conditions. Numerous MH have been observed to intervene in the pathophysiology of CVD via a myriad of molecular mechanisms, including antiinflammatory, anti-oxidant, and other beneficial properties, which translate into the amelioration of three essential aspects of the pathogenesis of CVD: Dyslipidemia, atherosclerosis, and hypertension. Although the preclinical data in this scenario is very rich, the true clinical impact of MH and their purported mechanisms of action is less clear, as large-scale robust research in this regard is in relatively early stages and faces important methodological challenges. This review offers a comprehensive look at the most prominent preclinical and clinical evidence currently available concerning the use of MH in the treatment of CVD from a bench-to-bedside approach.

A mixed herbal extract as an adjunctive therapy for attention deficit hyperactivity disorder: A randomized placebo-controlled trial. Integr Med Res 2021; 10:100714. [PMID: 33665099 PMCID: PMC7903061 DOI: 10.1016/j.imr.2021.100714] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 12/26/2020] [Accepted: 12/28/2020] [Indexed: 12/24/2022] Open
Abstract
Background Methylphenidate improves clinical symptoms and brain activity in attention deficit hyperactivity disorder (ADHD) patients through the attention-regulation network's dopamine system. Additionally, water-soluble extracts (HX106) of four plants (Gastrodia elata Blume, Liriope platyphylla Wang et Tang, Salvia miltiorrhiza Bunge, and Dimocarpus longan Lour) improve cognitive function. We hypothesized that the combination of HX106 and methylphenidate would improve ADHD symptoms and brain activity of the attention network more effectively than the combination of placebo and methylphenidate. Methods Twenty-seven patients with ADHD were administered a herbal mixture and methylphenidate (n=13), or placebo and methylphenidate (n=14) during a 4-week, randomized, double-blind, placebo-controlled clinical trial. Changes in ADHD symptoms (K-ARS scores), as well as brain activity and functional connectivity, were assessed at baseline and 4 weeks later. Results The HX106 group showed a greater improvement in total attention (16.8%) and inattention (17.2%) scores than the placebo group. The HX106 group showed increased brain activity within the left precuneus compared to the placebo group. The HX106 group also showed increased functional connectivity from the precuneus seed to the left middle temporal gyrus compared with the placebo group. In all participants, the changes in K-ARS scores were negatively correlated with changes in brain activity in the left middle temporal gyrus. Conclusions HX106 enhanced the effect of methylphenidate on ADHD symptoms and increased brain activity in the attention-regulation network. Therefore, HX106 may be an effective adjunctive therapy for patients with ADHD.

Abstract
Migraine is a recurrent disease with complex pathogenesis and is difficult to cure. At present, commercially available western migraine drugs are prone to generate side effects while treating the disease. Traditional Chinese medicine (TCM) avoids side effects via treatment with the principles of “treating both symptoms and root causes”, “overall adjustment”, and “treatment based on syndrome differentiation”. Three strategies of drug treatment were developed based on the syndromes, i.e., removing stasis, calming liver Yang, and reinforcing deficiency. Prescriptions of removing stasis mostly contain Chuanxiong rhizome (Chuan Xiong) to remove blood stasis by promoting blood circulation and improve properties of hemorheology, and Da Chuan Xiong Formula (DCXF) is a traditional prescription widely used in clinical practice. Prescriptions of calming liver Yang usually take Ramulus Uncariae cum Uncis (Gou Teng) as the main herb, which can calm the liver Yang via improving vasomotor function, and Tian Ma Gou Teng Decoction (TMGTD) is the representative drug. For reinforcing deficiency, Chinese doctors frequently utilize Angelica Sinensis (Dang Gui) and Astragali Radix (Huang Qi) to nourish blood and Qi in order to improve the weak state of human body; Dang Gui Bu Xue Decoction (DGBXD) is the commonly used prescription. These strategies not only treat the symptoms of diseases but also their root causes, and with the features of multiple targets, in multiple ways. Therefore, TCM prescriptions have obvious advantages in the treatment of chronic diseases such as migraine. In this review, we provided an overview of the pathogenesis of migraine and the function of representative TCM preparations in therapy of migraine as well as the mechanism of action according to effective researches, in order to provide reference and clue for further researches.

Moringa oleifera leaf extract induces vasorelaxation via endothelium-dependent hyperpolarization and calcium channel blockade in mesenteric arterial beds isolated from L-NAME hypertensive rats. Clin Exp Hypertens 2020; 42:490-501. [PMID: 31965874 DOI: 10.1080/10641963.2020.1714640] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/06/2023]
Abstract
BACKGROUND An aqueous extract of Moringa oleifera leaves (MOE) is known to cause relaxation of mesenteric resistance arteries of rats in which hypertension has been induced by the administration of L-NAME, but the mechanism(s) of action of MOE remains unclear. The purpose of this study was to investigate these mechanisms in mesenteric arterial beds isolated from L-NAME induced hypertensive rats. Methods: An investigation of vascular reactivity was conducted on isolated mesenteric arterial beds by measuring the changes in perfusion pressure using an in vitro system. RESULTS MOE (0.001-3 mg in 0.1 ml injection volume) caused a dose-dependent relaxation in methoxamine (5 µM) pre-contracted arterial beds, which was partially abolished by endothelium removal. The endothelium-dependent component of vasorelaxation was insensitive to both L-NAME (100 µM) and indomethacin (10 µM), while completely inhibited in high KCl (45 mM)-induced contraction. MOE (1 and 3 mg/ml) showed a dose-dependent inhibitory effect on CaCl2-induced contractions of denuded preparations in Ca2+-free medium containing a high KCl (60 mM) or methoxamine (10 µM). In Ca2+-free medium, MOE (3 mg/ml) also inhibited phenylephrine-induced contractions of denuded preparations. Conclusion: These findings suggest that MOE relaxes mesenteric arterial beds of L-NAME hypertensive rats via both endothelium-dependent and endothelium-independent mechanisms. The endothelium-dependent action occurred via endothelium-derived hyperpolarizing factor-mediated hyperpolarization. The endothelium-independent action was related to blocking the entry of extracellular Ca2+ via voltage-operated and receptor-operated Ca2+ channels, and inhibiting mobilization of sarcolemmal Ca2+ via inositol trisphosphate receptor Ca2+ channels. MOE may be potentially useful as a natural vasodilator against hypertension.

Antihypertensive effects of allicin on spontaneously hypertensive rats via vasorelaxation and hydrogen sulfide mechanisms. Biomed Pharmacother 2020; 128:110240. [PMID: 32480217 DOI: 10.1016/j.biopha.2020.110240] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 04/27/2020] [Accepted: 05/03/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Allicin, the principle active constituent in garlic, has been reported to have antihypertensive effects on drug-induced hypertension or renal hypertension in rats, but reports on spontaneously hypertensive rats (SHRs) are rare. Allicin is comprised of a variety of sulfur-containing compounds, and hydrogen sulfide (H2S) has been shown to have specific vasomotor effects. We therefore hypothesize that allicin may exert a vasorelaxant activity by inducing H2S production, and this eventually result in a reduction in blood pressure in SHRs. METHODS The in vivo antihypertensive effect of allicin was assessed using a tail-cuff method on SHRs. The in vitro vasorelaxant effect and in-depth mechanisms of allicin were explored on rat mesenteric arterial rings (RMARs) isolated from SD rats. RESULTS In the in vivo study, administration of allicin (7 mg/kg and 14 mg/kg, 4 weeks, i.g) dramatically decreased the blood pressure in SHRs, which was also shown to be attenuated by H2S synthase inhibitor (PAG, 32 mg/kg, i.g). In in vitro studies, allicin (2.50-15.77 mM) produced a concentration-dependent vasorelaxation on RMARs, which was obviously reduced by preincubation with PAG. The removal of endothelium led to a decline in allicin's vasorelaxation, which was almost completely mitigated when treatment was followed with PAG. Inhibitors of nitric oxide (NO) and prostaglandin (PGI2) pathways separately suppressed the vasorelaxation induced by allicin to a certain degree. When the RMARs incubated with PAG were treated with or without the above inhibitors in separate groups, the relaxations caused by allicin were almost identical under both these conditions. Moreover, allicin treatment increased cyclic guanosine monophosphate (cGMP) and cyclic adenosine monophosphate (cAMP) levels (downstream products of NO and PGI2 pathways), which was decreased by PAG. Additionally, allicin increased the acetylcholine-induced endothelium-derived hyperpolarizing factor (EDHF) -mediated relaxation, which was unaffected by PAG. CONCLUSION Allicin exhibits a potent antihypertensive effect through vasodilatory properties and H2S mechanisms. Moreover, the vasodilation of allicin is partially dependent on endothelium. The endothelium-dependent vasodilation of allicin is mediated by the NO-sGC-cGMP, PGI2-AC-cAMP and EDHF pathways, of which H2S participates in the first two but not the third one. The endothelium independent vasodilation can be predominantly attributed to H2S production.

Abstract
Vasodilatation is one of the key therapeutic strategies for the treatment of various cardiovascular diseases with high blood pressure. Therefore, development of drugs assisting blood vessel dilation is promising. It has been proven that many drugs display definite vasorelaxant effects. However, there are very few studies that systemically explore the effective vasodilators. In this work, we build a transcriptome-based functional gene module reference approach for systematic pursuit of agents with vasorelaxant effects. We firstly curate two functional gene modules that are specifically involved in positive and negative regulation of vascular diameter based on the known gene functional interaction knowledge. Secondly, a collection of gene expression profiles following herbal component treatment are collected from a public gene expression database. Then, the correlation of the gene modules is evaluated in each herbal component–induced gene expression profile by gene set enrichment analysis. The vasorelaxant effects of the candidate compounds can be predicted and ordered by the values of a defined index. Finally, the top 10 candidate compounds are experimentally tested for their vasorelaxant effects on vessel contraction induced by Phe in aortic rings. This strategy integrating different types of technologies is expected to help to create new opportunities for the development of novel vasodilators.

Abstract
Hypertension is one of the most common cardiovascular diseases, resulting in serious complications such as cardiovascular damage and chronic kidney disease. Tianshu capsule (TSC), composed of Chuanxiong (Ligusticum chuanxiong Hort) and Tianma (Gastrodiaelata Blume), has been widely used to treat the blood stasis type of headache and migraine in clinic. Results of previous research showed its antihypertensive effects, but the underlying mechanisms were still unclear. The purpose of this study was to evaluate the antihypertensive effect of TSC on spontaneously hypertensive rats by 1H NMR-based metabonomics and enzyme-linked immunosorbent assay (ELIAS), explore potential biomarkers and targets, and probe the potential mechanism of TSC on antihypertensive treatment. The results showed that TSC could decrease the product of oxidative stress (MDA) and enhance the activities of SOD and GSH-Px, down-regulate the expression of enzymes (LDHA, PKM2 and HK2) related to glycolysis, and perturb the levels of a series of amino acids (isoleucine, alanine, asparagine, citrate, etc.) and pathways. Multivariate statistical analyses showed remarkable changes in some endogenous metabolites after administrating TSC related to oxidative stress, amino acid metabolism and energy metabolism disturbances. Some enzymes (alanine-glyoxylate aminotransferase-2, tyrosine hydroxylase, dopa decarboxylase, etc.) related to metabolic biomarkers were predicted as the potential targets of TSC treatment on SHRs. The discoveries are helpful to understand the antihypertensive mechanism of TSC and provide theoretical evidence for its future research, development and clinical use.
