Bushmeleva K, Vyshtakalyuk A, Terenzhev D, Belov T, Nikitin E, Zobov V. Aronia melanocarpa Flavonol Extract-Antiradical and Immunomodulating Activities Analysis. PLANTS (BASEL, SWITZERLAND) 2023; 12:2976. [PMID: 37631187 PMCID: PMC10458422 DOI: 10.3390/plants12162976] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 08/04/2023] [Accepted: 08/14/2023] [Indexed: 08/27/2023]
Abstract
The study of Aronia melanocarpa's (A. melanocarpa) biological activity is focused on obtaining the crude extract and separation of the flavonol compounds. The extraction and fractionation of A. melanocarpa fruits, followed by quantitative analysis, were accomplished using high-performance liquid chromatography and Darco G-60 filtering. This approach enabled the quantification of flavonoids within each fraction. The antioxidative, immunomodulating activities and cytotoxicity with respect to the lymphoblast cell line RPMI-1788 were studied. The flavonol extract of A. melanocarpa has been shown to have a high capacity to neutralize free DPPH and AAPH radicals in vitro. It also caused an accelerated 'respiratory burst' formation of neutrophils and an increase in the metabolic reserves of cells in rats exposed to cyclophosphamide. The reference solution (an equivalent quercetin-rutin blend) contributed to a decrease in lipid peroxidation, intensifying phagocytosis processes. The studied compounds demonstrated their low influence on the leukocyte blood profile in animals.

Abstract
Over the past few decades, the green synthesis of nanoparticles has gained importance for their therapeutic efficacy and eco-friendly nature. Integrating green chemistry principles into multidisciplinary nanoscience research has paved the way for developing environmentally benign and sustainable methods for synthesizing gold and silver nanoparticles. In the present study, the flowers obtained from Clerodendrum infortunatum (L.), belonging to the family Verbenaceae, have been used for biosynthesizing silver nanoparticles (AgNPs) to evaluate the anthelmintic potential. UV-Vis spectroscopy, XRD, FTIR, SEM and TEM analyses were performed to ascertain the formation of AgNPs. Clerodendrum-derived AgNP (CLE-AgNP) has significantly affected the normal physiological functions of the poultry parasite Raillietina spp., a menace to the livestock industry. Our study manifests that CLE-AgNPs cause considerable distortion of the surface tegument of this cestode parasite leading to changes in the host-parasite interface. The histochemical localization studies of the tegument-associated enzymes viz. AcPase, AlkPase, ATPase and 5'-Nu, exposed to the drug, showed a substantial activity decline, thus establishing the anthelmintic potential of the CLE-AgNPs.

Abstract
Polyphenol has been used in treatment for some health disorders due to their diverse health promoting properties. These compounds can reduce the impacts of oxidation on the human body, prevent the organs and cell structure against deterioration and protect their functional integrity. The health promoting abilities are attributed to their high bioactivity imparting them high antioxidative, antihypertensive, immunomodulatory, antimicrobial, and antiviral activity, as well as anticancer properties. The application of polyphenols such as flavonoids, catechin, tannins, and phenolic acids in the food industry as bio-preservative substances for foods and beverages can exert a superb activity on the inhibition of oxidative stress via different types of mechanisms. In this review, the detailed classification of polyphenolic compunds and their important bioactivity with special focus on human health are addressed. Additionally, their ability to inhibit SARS-CoV-2 could be used as alternative therapy to treat COVID patients. Inclusions of polyphenolic compounds in various foods have demonstrated their ability to extend shelf life and they positive impacts on human health (antioxidative, antihypertensive, immunomodulatory, antimicrobial, anticancer). Additionally, their ability to inhibit the SARS-CoV-2 virus has been reported. Considering their natural occurrence and GRAS status they are highly recommended in food.

Translational suppression of SARS-COV-2 ORF8 protein mRNA as a Viable therapeutic target against COVID-19: Computational studies on potential roles of isolated compounds from Clerodendrum volubile leaves. Comput Biol Med 2021; 139:104964. [PMID: 34688170 PMCID: PMC8524706 DOI: 10.1016/j.compbiomed.2021.104964] [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: 09/14/2021] [Revised: 10/17/2021] [Accepted: 10/18/2021] [Indexed: 12/16/2022]
Abstract
The open reading frame 8 (ORF8) protein of SARS-CoV-2 has been implicated in the onset of cytokine storms, which are responsible for the pathophysiology of COVID-19 infection. The present study investigated the potential of isolated compounds from Clerodendrum volubile leaves to stall oxidative bursts in vitro and interact with ORF8 mRNA segments of the SARS-CoV-2 whole genome using computational tools. Five compounds, namely, harpagide, 1-(3-methyl-2-butenoxy)-4-(1-propenyl)benzene, ajugoside, iridoid glycoside and erucic acid, were isolated from C. volubile leaves, and their structures were elucidated using conventional spectroscopy tools. Iridoid glycoside is being reported for the first time and is thus regarded as a new compound. The ORF8 mRNA sequences of the translation initiation sites (TIS) and translation termination sites (TTSs) encoding ORF8 amino acids were retrieved from the full genome of SARS-CoV-2. Molecular docking studies revealed strong molecular interactions of the isolated compounds with the TIS and TTS of ORF8 mRNA. Harpagide showed the strongest binding affinity for TIS, while erucic acid was the strongest for TTS. The immunomodulatory potentials of the isolated compounds were investigated on neutrophil phagocytic respiratory bursts using luminol-amplified chemiluminescence technique. The compounds significantly inhibited oxidative burst, with 1-(3-methyl-2-butenoxy)-4-(1-propenyl)benzene having the best activity. Ajugoside and erucic acid showed significant inhibitory activity on T-cell proliferation. These results indicate the potential of C. volubile compounds as immunomodulators and can be utilized to curb cytokine storms implicated in COVID-19 infection. These potentials are further corroborated by the strong interactions of the compounds with the TIS and TTS of ORF8 mRNA from the SARS-CoV-2 whole genome.

Abstract
The global spread of the coronavirus infections disease − 2019 (COVID-19) and the search for new drugs from natural products particularly from plants are receiving much attention recently. In this study, the therapeutic potential of a new iridoid glycoside isolated from the leaves of Clerodendrum volubile against COVID-19 was investigated. Harpagide 5-O-β-D-glucopyranoside (HG) was isolated, characterised and investigated for its druglikeness, optimized geometry, and pharmacokinetics properties. Its immunomodulatory was determined by chemiluminescence assay using polymorphonuclear neutrophils (PMNs) in addition to T-cell proliferation assay. In silico analysis was used in determining its molecular interaction with severe acute respiratory syndrome coronavirus-2 (SARS-COV-2). HG displayed potent druglikeness properties, with no inhibitory effect on cytochrome P450 (1A2, 2C19, 2C9, 2D6 and 3A4) and a predicted LD50 of 2000 mg/kg. Its 1H-NMR chemical shifts showed a little deviation of 0.01 and 0.11 ppm for H-4 and H-9, respectively. HG significantly suppressed oxidative bursts in PMNs, while concomitantly inhibiting T-cell proliferation. It also displayed a very strong binding affinity with the translation initiation and termination sequence sites of spike (S) protein mRNA of SARS-COV-2, its gene product, and host ACE2 receptor. These results suggest the immunomodulatory properties and anti-SARS-COV-2 potentials of HG which can be explored in the treatment and management of COVID-19. Communicated by Ramaswamy H. Sarma

Abstract
Introduction:Doxorubicin (DOX), a well-known chemotherapeutic drug, has been reported to induce numerous toxic side effects including renal toxicity. This preliminary study was designed to investigate the ameliorative effects of methanolic leaf extract ofClerodendrum volubile(MECV) against DOX-induced nephrotoxicity in rats.Methods:Thirty male rats were divided into five groups; (a) Control group: rats were given 0.9% NaCl as vehicle, (b) DOX group: a single dose of DOX (25 mg/kg; i.p.) was administered and the rats were sacrificed 4 days after DOX injection, (c-e) Methanolic extract of C. volubile (MECV)-treated DOX groups: rats were given MECV (at the doses of 125, 250 and 500 mg/kg/d), respectively for 12 consecutive days, 8 days before and 4 days after the DOX administration.Results:DOX injection caused a significant increase (P<0.05) in serum creatinine and urea levels. The levels of renal antioxidant parameters: glutathione peroxidase, superoxide dismutase (SOD), catalase (CAT) and reduced glutathione were significantly (P<0.05) decreased in DOX-intoxicated rats with concomitant elevation of malondialdehyde level. Pretreatment with MECV restored antioxidant status, attenuated oxidative stress and improved kidney function markers. Pre-treatment with MECVprotected renal tissues against DOX-induced nephrotoxicity.Conclusion:The ameliorative effects ofC. volubileleaves on these renal biochemical parameters may be via its antioxidant action and may serve as a novel combination agent with DOX to limit its renal damage.

Abstract
INTRODUCTION Medicinal plants have long been recognized for their roles in the treatment and management of diabetes and its complications. The antioxidative and antidiabetic properties of Clerodendrum volubile flowers were investigated in vitro and ex vivo. METHODS The flowers were sequentially extracted with solvents of increasing polarity (n-hexane, ethyl acetate, ethanol and water). The concentrated extracts were subjected to in vitro antioxidant assays using the 2,2'-diphenyl-1-picrylhydrazyl (DPPH) scavenging and Ferric reducing antioxidant power (FRAP) protocols. Their inhibitory activities were investigated on α-glucosidase, pancreatic lipases, pancreatic ATPase and glucose-6-phosphatase activities. Their anti-oxidative and anti-apoptotic effects on Fe2+-induced oxidative injuries were also investigated in pancreatic and hepatic tissues ex vivo. RESULTS The extracts showed potent free radical scavenging activity and significantly (p < 0.05) inhibited all studied enzymes. The GSH level was significantly (p < 0.05) elevated in both tissues with concomitant increase in superoxide dismutase (SOD) and catalase activities as well as reduced levels of malondialdehyde (MDA). The extracts significantly (p < 0.05) suppressed DNA fragmentation in hepatic tissue. These activities were dose-dependent. The ethanol extract showed the best activity and can be attributed to the synergetic effect of its chemical constituents identified via gas chromatography-mass spectroscopy (GC-MS). CONCLUSION These results suggest the antioxidative, antidiabetic and anti-obesogenic potentials of C. volubile flowers.

Abstract
AbstractBackgroundNon-alcoholic fatty liver disease, which occurs in people who are not alcohol drinkers, describes some of the pathogenic conditions that may be in the least characterized by simple steatosis or can be as serious as non-alcoholic steatohepatitis and cirrhosis. Its mechanistic pathogenesis has been said to arise from insulin resistance and oxidative stress, which may be compounded by obesity. An experimental model showing, systemic insulin resistance, obesity and accumulated hepatic fatty acids was created in adult male rats using high-fat diet manipulation and surgical removal of the left kidney (uninephrectomy). This study sought to identify the impact of these multiple burdens on the liver mitochondrial membrane permeability transition pore opening, and the possible in vitro effects of the extracts ofClerodendrum volubileandManihot esculentaleaves on the membrane permeabilization.ResultsThe results indicated that the methanolic extract ofClerodendrum volubileleaf inhibited mitochondrial membrane pore opening in the insulin resistance condition or when it is followed by uni-nephrectomy, while the ethanolic extract ofManihot esculentaleaf does the same in the insulin resistance condition both prior to and following uni-nephrectomy.ConclusionSince the vegetable extracts were able to abrogate mitochondrial pore opening at low concentrations, the structural integrity of the mitochondria can possibly be restored over time if treated by the vegetable extracts. Research efforts should, therefore, be made to harness the drugability of the bioactives of these vegetables for use in the treatment of non-alcoholic fatty liver disease arising from insulin resistance and renal failure.

Abstract
Background The negative impact of diabetes on the liver is well documented. The white butterfly (Clerodendrum volubile) leaf has been used in traditional practices for the treatment of various diseases, such as hypertension, diabetes, and rheumatism, but without scientific validation. This work was designed to evaluate the hepatoprotective properties of Clerodendrum volubile leaves on oxidative stress in streptozotocin (STZ)-induced diabetes in rats. Methods The rats were divided into ten groups of five rats each. Diabetes was induced by a single injection of STZ (65 mg/kg body weight; i.p), while the C. volubile extract (at the respective doses of 50, 100 and 200 mg/kg body weight) was given to diabetic and non-diabetic rats orally for 14 days. Metformin (100 mg/kg body weight) served as the positive control. Biochemical assays were conducted on the plasma for hematological parameters, along with hepatic marker damages and antioxidant enzyme determination in vivo to assess hepatic injury. Results The diabetic control rats showed significant increase (p<0.05) in marker enzymes: aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and malondiadehyde with reduction in reduced glutathione, glutathione peroxidase, superoxide dismutase, catalase activities and plasma total protein content. Likewise, there were alterations in hematological indices in the diabetic control rats when compared with the normal control. However, treatment with C. volubile caused a reversal of the above parameters towards normal levels, thereby suggesting the modulating effect of the extract on oxidative stress, which may be a result of the high polyphenolic content and antioxidant capacity. Conclusions The protection of the liver tissues and the modulation of oxidative stress in STZ diabetic rats compare favorably to metformin, a standard antidiabetic drug.

Abstract
The toxicity and safety associated with the use of medicinal plants remains a major concern. In this study, the antidiabetic properties of the dichloromethane (DCM) fraction of C. volubile leaves were investigated in vitro. Its cytotoxic effect and mechanism of toxicity were also investigated in Human Embryonic Kidney (HEK293) cells. The fraction was subjected to in vitro antioxidant assays using the 2,2'-diphenyl-1-picrylhydrazyl (DPPH) scavenging and Ferric reducing antioxidant power (FRAP) protocols. Its enzyme-inhibitory properties were investigated on α-glucosidase and α-amylase activities. Gas Chromatography Mass Spectroscopy (GCMS) and Fourier Transform Infrared (FTIR) spectroscopic analysis were used to identify its phytoconstituents. Cytotoxicity was determined via MTT assay. The treated cells were assayed for reduced glutathione (GSH), non-protein thiol, nitric oxide and malondialdehyde (MDA) levels, as well as Superoxide Dismutase (SOD), catalase, myeloperoxidase and ATPase activities. Cell apoptosis and/or morphological changes were determined using the acridine orange and ethidium bromide (AO/EB) dual staining method. The fraction showed significant (p < 0.05) antioxidant and enzyme-inhibitory activity. It showed significant (p < 0.05) cytotoxic effect against HEK293 cells with concomitant depletion of antioxidative and elevation of proinflammatory biomarkers. Morphological changes were examined in the cells with an apoptotic index of 0.84. 1,1-Dodecanediol, diacetate was identified as the most predominant compound, while aromatics and amines as the most functional groups present in the fraction. These results suggest the antidiabetic and cytotoxic effects of C. volubile leaves. The toxicity can be attributed to induced oxidative stress and proinflammation with concomitant depletion of ATP leading to apoptosis of the cells.

Abstract
White Butterfly (Clerodendrum volubile) leaf is commonly used in traditional medicine for the management of various diseases including diabetes without the full understanding of the scientific basis for its use. This study sought to evaluate the antihyperglycemic, antihyperlipidemic and antioxidant effect of C. volubile leaves in streptozotocin (STZ)-induced diabetic rats. Aqueous extract of C. volubile was prepared and its effect assessed on relevant enzymes associated with diabetes. Fifty male Wistar rats were randomly separated into 10 groups each containing five rats. The induction of diabetes in rats was by a single intraperitoneal injection of STZ (65 mg/kg body weight) while C. volubile extract was administered orally to diabetic and non-diabetic animals, at the doses of 50, 100 and 200 mg/kg body weight for 14 days. Metformin (100 mg/kg body weight) served as positive control. Clerodendrum volubile extract inhibited α-glucosidase (IC50 = 0.20 mg/ml) and α-amylase (IC50 = 0.58 mg/ml). Furthermore, administration of C. volubile extract significantly reduced the elevated plasma glucose level and body weight, improved kidney functions, attenuated oxidative stress by decreasing MDA levels, enhancing superoxide dismutase, catalase and glutathione peroxidase activities, reinstated the lipid profile to nearly normal level and restored pancreatic histological integrity in diabetic rats. The results reveal that C. volubile represents a source of phytochemicals that exerts their antidiabetic effects through the modulation of glycemic and atherogenic indices as well as mitigation of free-radical-mediated damage.

Abstract
Type 2 diabetes is the most prominent of all diabetes types, contributing to global morbidity and mortality. Availability and cost of treatment with little or no side effect especially in developing countries, remains a huge burden. This has led to the search of affordable alternative therapies especially from medicinal plants. In this study, the antidiabetic effect of the methanolic extract, dichloromethane (DCM), butanol (BuOH) and aqueous fractions of Clerodendrum volubile leaves were investigated in type 2 diabetic rats for their effect on glucose homeostasis, serum insulin level and hepatic biomarkers, lipid profile, pancreatic redox balance and Ca2+ levels, and β-cell distribution and function. The DCM was further fractionated to isolate the active compounds, biochanin and 5,7,4'-trimethoxykaempferol. They were investigated for their toxicity and ADMET properties, α-glucosidase and angiotensin I converting enzyme (ACE) inhibitory activities in silico. There were significant (p < 0.05) decrease in blood glucose, cholesterol, LDL-C, vLDL-C, triglyceride, AST and ALT levels in all treated groups, with DCM fraction showing the best activity. All treated rats showed significantly (p < 0.05) improved anti-oxidative activities. Treatment with the DCM fraction led to significant (p < 0.05) increased serum insulin and pancreatic Ca2+ levels, as well as improved β-cell distribution and function. DCM fraction also showed improved glucose tolerance. DCM fraction dose-dependently inhibited ACE activity. The toxicity class of the isolated compounds was predicted to be 5. They were also predicted to be potent inhibitors of cytochrome P (CYPs) 1A2, 2D6 and 3A4. They docked well with α-glucosidase and ACE. These results indicate the therapeutic potential of the plant against type 2 diabetes, with the DCM fraction being the most potent which may be attributed to the isolated flavones. It further suggests antihypertensive potentials of the DCM fraction. However, inhibition of CYPs by the flavones may suggest caution in usage with other prescribed drugs metabolized by these enzymes.
