Natural angiotensin converting enzyme inhibitors: A safeguard against hypertension, respiratory distress syndrome, and chronic kidney diseases. Phytother Res 2023; 37:5464-5472. [PMID: 37675925 DOI: 10.1002/ptr.7987] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 08/05/2023] [Accepted: 08/08/2023] [Indexed: 09/08/2023]
Abstract
Hypertension is a serious concern as it is one of the causes of kideny failure and pulmonary fibrosis. An important therapeutic strategy for treating chronic hypertension is to inhibit the angiotensin converting enzyme (ACE). ACE inhibition reduces kidney damage, pulmonary artery pressure, and high blood pressure. Due to their high efficacy and low risk of side effects, natural renin-angiotensin system inhibitors have drawn increasing attention over the past decades. Alkaloids, amino acids, anthocyanidins, flavonoids, glucosinolates, isoflavonoids, phenolic acids, polyphenolics, and triterpenoids are among the bioactive metabolites pocessing an impressive ACE inhibitory activity. Many herbs including Rosmarinus officinalis, Hibiscus sabdariffa, Curcuma longa, Rauwolfia serpentina, Emblica officinalis, Cynara scolymus, Punica granatum, Mucuna pruriens, Capsicum annuum, and Moringa olifera were found having ACE inhibitory activities comparable to captopril and enalpril. These enticing natural ACE inhibitors deserve to be a safeguard medicine against hypertension, respiratory distress syndrome, and chronic kidney diseases. More clinical trials are required before new natural compounds and herbs can be used to treat chronic hypertension and its ramifications, such as respiratory distress syndrome and kidney failure.

Biologically Synthesized Peptides Show Remarkable Inhibition Activity against Angiotensin-Converting Enzyme: A Promising Approach for Peptide Development against Autoimmune Diseases. BIOMED RESEARCH INTERNATIONAL 2022; 2022:2396192. [PMID: 35769673 PMCID: PMC9236789 DOI: 10.1155/2022/2396192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 05/26/2022] [Accepted: 06/07/2022] [Indexed: 11/17/2022]
Abstract
Angiotensin-converting enzyme (ACE) regulates several biological functions besides its vital role in immune functions. ACE is elevated in immune cells in inflammatory diseases including atherosclerosis, granuloma, chronic kidney disease, and also autoimmune diseases, like multiple sclerosis, rheumatoid arthritis, and type I diabetes. No significant information prevails in the literature regarding the isolation, identification, and profiling of potential ACE inhibitory peptides. In the present study, indigenous crop varieties like seeds (peanut, corn, oat, sunflower, chickpea, parsley, cottonseed, papaya, sesame, and flaxseed) were used to evaluate their ACE inhibition activity. Variables including hydrolysis time, enzyme-to-substrate ratio (E/S), pH, and temperature were standardized to acquire the most suitable and optimum ACE inhibition activity. Seeds of cotton, chickpea, and peanuts displayed remarkably maximum ACE inhibition activity than other plants. The study disclosed that maximum ACE inhibitory activity (86%) was evaluated from cottonseed at pH 8.0, temperature of 45°C, hydrolysis time of 2 hrs, and enzyme to the substrate (E/S) ratio of 1 : 5 followed by peanuts (76%) and chickpea (55%). SDS-PAGE confirmed that vicilin protein is present in cottonseed and peanut seed while cruciferin and napin proteins are present in chickpeas. LC-MS/MS analysis disclosed potential novel peptides in hydrolyzed cottonseed that can be ascribed as potential ACE inhibitors which have never been reported and studied earlier. The current study further showed that cottonseed peptides due to their promising ACE inhibitory activity can be a valuable source in the field of ACE inhibitor development.

Abstract
Pulasan (Nephelium mutabile Blume) is an underutilized fruit native to tropical countries, including Malaysia, Thailand, and Indonesia. To date, the medicinal potential of pulasan remains unexplored, although this fruit shares the same genus with the well-known rambutan (Nephelium lappaceum). Therefore, the current study aims to examine the antioxidant properties of different parts of pulasan (flesh, rind, and kernel) and investigate the bioactive profile, anti-hypertensive and hypoglycemic properties of pulasan rind. Pulasan were extracted using different solvents, including distilled water, methanol, and ethanol. The antioxidant capacity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH), Trolox equivalent antioxidant capacity (TEAC), and ferric reducing antioxidant power (FRAP), and the antioxidant component was identified by total flavonoid content (TFC) and total phenolic content (TPC). The bioactive profile of pulasan rind was characterized by high-performance liquid chromatography (HPLC). The anti-hypertensive and hypoglycemic properties of pulasan rind were determined with angiotensin-converting enzyme (ACE) assay and alpha-amylase inhibition assay, respectively. Emerging findings revealed that pulasan rind exhibited the highest antioxidant capacity (DPPH, TEAC, and FRAP) in all extraction solvents and antioxidant components (TPC and TFC) in ethanolic extract. The ethanolic extracts of pulasan rind also had higher ACE and alpha-amylase inhibition activities than the distilled water extracts. Geraniin, chlorogenic acid, catechin, corilagin, syringic acid, and naringenin of pulasan rind may function as anti-hypertensive agents.

Abstract
G-protein-coupled receptors (GPCRs) are the largest family of cell surface signaling receptors known to play a crucial role in various physiological functions, including tumor growth and metastasis. Various molecules such as hormones, lipids, peptides, and neurotransmitters activate GPCRs that enable the coupling of these receptors to highly specialized transducer proteins, called G-proteins, and initiate multiple signaling pathways. Integration of these intricate networks of signaling cascades leads to numerous biochemical responses involved in diverse pathophysiological activities, including cancer development. While several studies indicate the role of GPCRs in controlling various aspects of cancer progression such as tumor growth, invasion, migration, survival, and metastasis through its aberrant overexpression, mutations, or increased release of agonists, the explicit mechanisms of the involvement of GPCRs in cancer progression is still puzzling. This review provides an insight into the various responses mediated by GPCRs in the development of cancers, the molecular mechanisms involved and the novel pharmacological approaches currently preferred for the treatment of cancer. Thus, these findings extend the knowledge of GPCRs in cancer cells and help in the identification of therapeutics for cancer patients.

Abstract
Angiotensin-converting enzyme (ACE) inhibitors are antihypertensive medications often used in the treatment of diabetes-related complications. Synthetic ACE inhibitors are known to cause serious side effects like hypotension, renal insufficiency, and hyperkalaemia. Therefore, there has been an intensifying search for natural ACE inhibitors. Many plants or plant-based extracts are known to possess ACE-inhibitory activity. In this review, articles focusing on the natural ACE inhibitors extracted from plants were retrieved from databases like Google Scholar, PubMed, Scopus, and Web of Science. We have found more than 50 plant species with ACE-inhibitory activity. Among them, Angelica keiskei, Momordica charantia, Muntingia calabura, Prunus domestica, and Peperomia pellucida were the most potent, showing comparatively lower half-maximal inhibitory concentration values. Among the bioactive metabolites, peptides (e.g., Tyr-Glu-Pro, Met-Arg-Trp, and Gln-Phe-Tyr-Ala-Val), phenolics (e.g., cyanidin-3-O-sambubioside and delphinidin-3-O-sambubioside), flavonoids ([-]-epicatechin, astilbin, and eupatorin), terpenoids (ursolic acid and oleanolic acid) and alkaloids (berberine and harmaline) isolated from several plant and fungus species were found to possess significant ACE-inhibitory activity. These were also known to possess promising antioxidant, antidiabetic, antihyperlipidemic and anti-inflammatory activities. Considering the minimal side effects and lower toxicity of herbal compounds, development of antihypertensive drugs from these plant extracts or phytocompounds for the treatment of diabetes-associated complications is an important endeavour. This review, therefore, focuses on the ACE inhibitors extracted from different plant sources, their possible mechanisms of action, present status, and any safety concerns.

Abstract
Picrorhiza kurroa Royle ex Benth. is a high-altitude plant having great medicinal value. However, its medicinal value at the peptide level is still unknown, which limits its utility in the development of peptide-based therapeutics. Here, we identify 65 peptides fromP. kurroa hydrolysate. Sequence analysis suggests that one novel bioactive peptide, ASGLCPEEAVPRR (BP1), has antioxidant potential and shows angiotensin-converting enzyme (ACE) and dipeptidyl peptidase-IV (DPP-IV) inhibitory activities. The molecular docking study showed that BP1 has a lower binding energy and strong affinity toward active pockets of ACE and DPP-IV, which explains its higher ACE [IC50 = 59.90 ± 9.52 μg/mL (43.40 μM)] and DPP-IV [IC50 = 3.04 ± 0.26 μg/mL (2.2 μM)] inhibitory activities. BP1 protects HEK293 cells from H2O2-induced oxidative damage by inhibiting intracellular reactive oxygen species (ROS) and malondialdehyde accumulation and activating the intrinsic antioxidant defense system. Additionally, phase-contrast microscopy studies revealed that pre-treatment of BP1 to HEK293 cells before exposure to H2O2 retains the normal morphology and blocks apoptosis. Furthermore, it also suppresses ROS-induced mitochondrial apoptosis via restoring the mitochondrial membrane potential (ΔΨm) and inhibiting caspase 3/7 activity. Therefore, BP1 has antioxidant potential and ACE and DPP-IV inhibitory activities that could be used for peptide-based formulation(s) in pharmaceuticals to treat diabetes, cardiovascular diseases, and other diseases associated with ROS.

Abstract
Probiotics can release many bioactive peptides that confer a myriad of benefits to the host health. However, exploring new bioactive peptides secreted by probiotics is hampered by lots of matrix-related interference peptides from the medium, and the low abundance. To this end, a new approach integrating mixed-mode cationic exchange based solid-phase extraction (MCX-SPE) coupled with liquid chromatography-mass spectrometry (LC-MS) and feature-based molecular networking (FBMN) was developed. FBMN's intuitive visualization results enabled twenty-five novel peptides to be quickly discovered and characterized from the cultures of three strains of Bifidobacterium, B. animalis, B. longum, and B. pseudolongum. Interestingly, four were uniquely secreted by B. animalis treated with gypenosides, and one showed ACE inhibitory effect with an IC50 value of 193.22 μM. Consequently, this approach could serve as a powerful tool for quickly discovering bioactive peptides from the complex metabolites of probiotics, which contributes to the development of functional foods and nutraceuticals.

Abstract
Angiotensin-converting enzyme (ACE) liable for the regulation of blood pressure was purified from human plasma by affinity chromatography. Impact of water and butanol extracts of Matricaria chamomilla L. on purity ACE was examined. ACE was purified using the affinity chromatography method. The enzyme activity was evaluated at 345 nm by a spectrophotometer. Extracts of M. chamomilla plant with butanol and water were prepared. Lisinopril was utilized as a specific inhibitor. ACE was purified 3,659-fold from human plasma and the specific activity was 1,350 EU/mg protein. The molecular weight and purity of ACE were found by SDS-PAGE and two bands of 60 and 70 kDa on the gel were detected. Water and butanol extracts of M. chamomilla demonstrated inhibitor impact on ACE activity. IC50 constants for water and butanol extracts of M. chamomilla were computed to be 1.292 and 0.353 mg/mL, respectively. The type of inhibition for whole inhibitors was identified as noncompetitive. IC50 and Ki constants for lisinopril were calculated to be 0.781 and 0.662 nM, respectively. These results indicate that butanol and water extracts of M. chamomilla may have an ACE inhibitor potential.

Abstract
Background:
The Rotonda’s Red Eggplant belongs to the family of Solanum aethiopicum
and it is cultivated in a specific area of Potenza (Basilicata, South of Italy) including villages of Rotonda,
Viggianello, Castelluccio Superiore and Castelluccio Inferiore. The Red Eggplant cultivated in
this area has gained the PDO, “Protected Designation of Origin”.
Objective:
The aim of this research was to evaluate the use of PDO Rotonda’s Red Eggplant extract
as a possible nutraceutical supplement. The antioxidant, antihypertensive, hypoglycemic, and hypolipidemic
properties were in vitro evaluated.
Methods:
The antioxidant activity was investigated by evaluating the scavenging properties against
2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)
(ABTS) radicals and by performing the Ammonium Molybdate and Folin-Ciocalteu assay. The hypoglycemic
and antihypertensive activity was studied by evaluating the α-Amylase, α-Glucosidase
and Angiotensin Converting Enzyme, respectively, inhibiting activity. In order to evaluate the hypolipidemic
activity, the pancreatic lipase inhibiting property was determined and Oil Red O staining
assay was performed. Finally, to evaluate the possible use of this extract as a minerals supplement,
Selenium, Potassium and Chrome bioaccessibility was studied.
Results:
The obtained results underline the good antioxidant, hypoglycemic, antihypertensive and
hypolipidemic in vitro properties of the PDO Rotonda’s Red Eggplant extract. Moreover, the obtained
data show a higher minerals bioaccessibility and this higher value could be ascribable to the
natural phytocomplex of PDO Rotonda’s Red Eggplant, which increases the minerals bioaccessibility
if compare it with a control sample.
Conclusion:
The obtained results show that PDO Rotonda’s Red Eggplant extract, might be used as
a possible nutraceutical supplement, along with traditional therapies, both for its biological properties
and for its minerals bioaccessibility value.

Abstract
China is a large country that produces Camellia oleifera Abel seed meal (COASM), a by-product of tea-seed oil, which is only used as an organic fertilizer, resulting in a serious waste of high-quality resources. The preparation of the ACE inhibitory peptide from COASM and the study of its functional properties are of practical importance in improving the comprehensive utilization of COASM. Our manuscript presents an optimized preparation of ACE inhibitory peptides with alkaline protease and enzyme kinetics parameters. Ultrafiltration, gel chromatography, and RP-HPLC purification were conducted for ACE inhibitory peptides, and peptide molecular weight distribution and amino acid composition were analyzed in the enzymolysis liquid. The following were the conditions of the optimized enzymatic hydrolysis to obtain ACE inhibitory peptides from COASM: 15 times of hydrolysis in distilled water for 3.5 h at 50°C, pH = 8.5, substrate concentration of 17 mg/g, and addition of 6% (w/w) alkaline protease. Under this condition, the peptides produced exhibited an ACE inhibition rate of 79.24%, and the reaction kinetics parameters are as follows: Km = 0.152 mg/mL and Vmax = 0.130 mg/mL·min. The majority of ACE inhibitory peptides from COASM have molecular weight below 1 kDa, and a high ACE inhibitory rate was achieved after dextran gel chromatography separation and purification (whose IC50 was 0.678 mg/mL). The hydrophobic amino acid content in this fraction reached 51.21%.

Abstract
Surface plasmon resonance (SPR) biosensor has been utilized for monitoring analyte-ligand interactions in modern drug discovery processes. SPR biosensors measure the change in refractive indexes over the course of analyte molecules' binding to a specific immobilized ligand on sensor chip. This effort highlights a comprehensive SPR study besides enzymatic assay for discovery of new Angiotensin Converting Enzyme (ACE) inhibitors via screening of medicinal plants. At first, five medicinal plants were selected as potential sources for developing new ACE inhibitors through hydrolyzing hippuryl-L-histidyl-L-leucine (HHL) assay. The interaction of selected extracts with immobilized ACE on the sensor chip (500D) confirmed that the Onopordum acanthium L. had the greatest ACE inhibition activity among the set of compounds and its active compound (onopordia) was isolated. SPR biosensor used to evaluate binding affinity of onopordia and ACE. Equilibrium constant (KD), and changes in Gibb's free energy of the binding (ΔGbinding) values for the interaction of onopordia with ACE were found to be 10.24 μM and -28.48 kJ/mol, respectively. Computational analysis supported the binding of onopordia to the ACE active site. Kinetic and thermodynamic parameters of binding revealed that onopordia is an acceptable ACE inhibitor and could treat hypertension. SPR biosensor can be used to improve the drug discovery process for many important classes of drug targets due to its great sensitivity.

Abstract
Background In the search of safe and effective lead molecules from natural sources, Mucuna pruriens (MP) L. (Fabaceae) seeds were utilized for exploring the antihypertensive potential. Traditionally, it is used as diuretic and hypotensive. Methods Bioassay-guided fractions were utilized for the isolation of active compounds by column chromatography. IC50 value, enzyme kinetics and inhibition mechanism were determined. In vivo time and dose-dependent hypotensive study followed by changes in mean arterial pressure (MAP) induced by angiotensin I (3 nmol/kg), angiotensin II (3 nmol/kg), and bradykinin (10 nmol/kg) in anesthetized rats was done. Plasma and tissue angiotensin I-converting enzyme (ACE) activities were also determined. Results Phytochemical analysis by spectroscopic techniques revealed the presence of known compounds like genistein, ursolic acid and L-DOPA from the ethyl acetate and water fraction, respectively. In vitro study revealed MP ethyl acetate (MPEA) fraction and genistein as the most active fraction (IC50 156.45 µg/mL) and compound (IC50 253.81 µM), respectively. Lineweaver-Burk plots revealed a non-competitive mode of inhibition. ACE protein precipitation was the suggested mechanism for inhibition. The extract showed a time- and dose-dependent decrease in MAP. Genistein was able to dose-dependently reduce the MAP, up to 53±1.5 mmHg (40 mg/kg, i.v.). As compared to control, it showed a dose-dependent decrease in plasma ACE activity of 40.61 % and 54.76 % at 10 mg/kg and 20 mg/kg, respectively. It also decreased the ACE activity in the aorta (107.67nM/ml min at 10 mg, p<0.001; 95.33nM/ml min at 20 mg p<0.001). Captopril was used as a standard for various in vitro and in vivo assays. Conclusions The study revealed the antihypertensive potential of MP seed compounds via ACE inhibition.

Abstract
The renin-angiotensin-aldosterone system is a signaling pathway which responsible in the blood pressure regulation. Angiotensin-converting enzyme (ACE) is one of the key elements responsible for the hypertensive mechanism. It converts angiotensin-I to angiotensin-II. The discovery history of the ACE inhibitory activity assay method has been through a long stage for decades and development continues until today. The ACE inhibitory activity has become an effective screening method in the search for new antihypertensive agents from herbal plants. Some of in vitro assay methods were used to examine the activity of ACE inhibitors based on the substrate usage, such as; Cushman and Cheung Method using a substrate hippuryl-histidyl-leucine (HHL), Holmquist method using a substrate furanacryloyl-tripeptide, Elbl and Wagner method using a substrate benzoil-[l-14C] glicyl-L-histidine-L-leucine, Carmel and Yaron method using a substrate o-aminobenzoylglycyl-p-nitrophenylalanilproline, and Lam method using 3-hydroxybutyrylglycyl-glycyl-glycine as substrate. Several different methods to measure the results of enzymatic reactions or separating substrate with products, including spectrophotometric, fluorometric, high-performance liquid chromatography, electrophoresis, and radiochemistry. Application of the test method for screening the ACE inhibitors activity and investigation of active compounds from natural products can be done easily with this method, it is very helpful in research because the results obtained are simple, accurate, and rapid.

In Silico Investigation of Traditional Chinese Medicine for Potential Lead Compounds as SPG7 Inhibitors against Coronary Artery Disease. Molecules 2016; 21:molecules21050588.

Abstract
Coronary artery disease (CAD) is the most common cause of heart attack and the leading cause of mortality in the world. It is associated with mitochondrial dysfunction and increased level of reactive oxygen species production. According to the Ottawa Heart Genomics Study genome-wide association study, a recent research identified that Q688 spastic paraplegia 7 (SPG7) variant is associated with CAD as it bypasses the regulation of tyrosine phosphorylation of AFG3L2 and enhances the processing and maturation of SPG7 protein. This study aims to identify potential compounds isolated from Traditional Chinese Medicines (TCMs) as potential lead compounds for paraplegin (SPG7) inhibitors. For the crystallographic structure of paraplegin, the disordered disposition of key amino acids in the binding site was predicted using the PONDR-Fit protocol before virtual screening. The TCM compounds saussureamine C and 3-(2-carboxyphenyl)-4(3H)-quinazolinone, have potential binding affinities with stable H-bonds and hydrophobic contacts with key residues of paraplegin. A molecular dynamics simulation was performed to validate the stability of the interactions between each candidate and paraplegin under dynamic conditions. Hence, we propose these compounds as potential candidates as lead drug from the compounds isolated from TCM for further study in drug development process with paraplegin protein for coronary artery disease.

Abstract
G protein-coupled receptors (GPCRs) regulate an array of fundamental biological processes, such as growth, metabolism and homeostasis. Specifically, GPCRs are involved in cancer initiation and progression. However, compared with the involvement of the epidermal growth factor receptor in cancer, that of GPCRs have been largely ignored. Recent findings have implicated many GPCRs in tumorigenesis, tumor progression, invasion and metastasis. Moreover, GPCRs contribute to the establishment and maintenance of a microenvironment which is permissive for tumor formation and growth, including effects upon surrounding blood vessels, signaling molecules and the extracellular matrix. Thus, GPCRs are considered to be among the most useful drug targets against many solid cancers. Development of selective ligands targeting GPCRs may provide novel and effective treatment strategies against cancer and some anticancer compounds are now in clinical trials. Here, we focus on tumor related GPCRs, such as G protein-coupled receptor 30, the lysophosphatidic acid receptor, angiotensin receptors 1 and 2, the sphingosine 1-phosphate receptors and gastrin releasing peptide receptor. We also summarize their tissue distributions, activation and roles in tumorigenesis and discuss the potential use of GPCR agonists and antagonists in cancer therapy.
