[PMID: 39149011 PMCID: PMC11325353 DOI: 10.1016/j.heliyon.2024.e34934] [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: 04/22/2024] [Revised: 07/12/2024] [Accepted: 07/18/2024] [Indexed: 08/17/2024] Open
Abstract
The fruit of Saba senegalensis is respectively known among local folks in Ghana, Senegal, and Burkina Faso as εsononantin, maad and weda. The plant has been used traditionally, ethnobotanically, and medicinally in most West African countries. The phytochemicals that have been discovered in various extracts of S. senegalensis parts include alkaloids, coumarins, anthracene glycosides, anthocyanosides, anthocyanins, coumarins, flavonoids, saponins, saponin glycosides, sterols, condensed tannins, tannins, triterpenes, and triterpenoids. Presently, isolation and characterisation of phytochemicals from various parts of S. senegalensis has not been fully explored since scientists have isolated only two steroidal alkaloids from the stem of the plant namely Irehine and Homoandrost-9-ene-17β,17aβ-diol-3β-(methylamino)-17aα-methyl-12-one. The phytochemicals have shown biological properties such as anti-oxidant, anti-inflammatory, anthelmintic, anti-microbial, analgesic, larvicidal, ovicidal, myostimulant, hypotensive, anti-diabetic, anti-lipid peroxidation and anti-mycobacterial effects. Additionally, isolation and characterisation of medicinally beneficial phytochemicals from various parts of the plant, namely latex, leaf, stem, flower, root, fruit, and bark should be comprehensively investigated. Thus, this current review summarises the traditional uses, phytochemicals, and biological properties of various parts of the plant.

Leaves of Allium cepa and Xylopia aethiopica fruits as potent sources of natural antioxidant for stabilization of viscera FISH oil during accelerated storage. Heliyon 2024; 10:e31225. [PMID: 38799740 PMCID: PMC11126847 DOI: 10.1016/j.heliyon.2024.e31225] [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: 03/08/2024] [Revised: 05/10/2024] [Accepted: 05/13/2024] [Indexed: 05/29/2024] Open
Abstract
The present study investigated the antioxidant activities of methanolic extracts of two local plants and their capacities to preserve the quality of viscera fish oil during storage. The total phenolic, total flavonoids and tannins contents were analyzed by colorimetry, the preliminary antioxidant tests done and identification of phenolic compounds by HPLC-DAD (Diode Array Detector) and ESI-MS. After these evaluation, the plant extracts were added in viscera fish oil at concentration 200-1000 ppm. The oxidative stability of these fish oil samples was evaluated by measuring their qualities indices during 16 days at 70 °C. Here, oils were collected at the day 0, 4, 8, 12 and 16. The total phenolic, flavonoids and tannins contents in Xylopia aethiopica fruits were 15.62 g Eq acid galic/100g of dry extract, 10.85 mg Eq quercetin/100g of dry extract and 0.79 mg Eq cathechin/100 mg of dry extract. Those of Allium cepa leaves were 6.85 g Eq acid galic/100g of dry extract, 1.50 mg Eq quercetin/100g of dry extract and 0.11 mg Eq cathechin/100 mg of dry extract. All the methanolic extracts exhibited antioxidant activity. The results recorded after FRAP assay revealed the low IC50 (12.87 mg/mL) in Allium cepa extract compared to that of Xylopia aethiopica extract (44.90 mg/mL). These local plants contain many classes of phenolic compounds and they can be used in oil and fat industries as alternative of synthetic antioxidants.

Abstract
In this study, the total phenolic and flavonoid contents (TPC and TFC), secondary metabolite composition (LC-HRMS/MS analyses) and antioxidant potential (DPPH, ABTS, GOR, CUPRAC, and phenanthroline assays) of Linum trigynum L. (LT) extracts were determined. Our results showed for the first time that the extracts (PE, CHCl3, AcOEt, and n-BuOH) of LT exert antioxidant activity. The AcOEt and n-BuOH extracts were the most antioxidant compared to the standards, and had a higher amount of TPC (323.51 ± 0.62; 229.98 ± 6.80 µg GAE/mL) and TFC (183.75 ± 1.17 and 157.50 ± 1.77 µg QE/mL), resectively. The high antioxidant properties of these extracts may be due to their major compounds (phenolic compounds) detected by LC-HRMS/MS analyses including flavonoids (40 compounds) and phenolic acids and derivatives (18 and 19 compounds, respectively). AcOEt and n-BuOH extracts of LT can be used as an excellent source of antioxidant phytochemicals to prevent or treat various diseases.

Abstract
As one of the main sources of natural antioxidants, flowering plants play a role in the prevention and treatment of many diseases directly and indirectly. Honey is considered as an important nutrient in the supply of natural antioxidants, the amount of which is directly dependent on the plant origin and geographical location of the bee feeding place. The existence of valuable communities of native and endemic plant species has turned Alborz, Zagros and Azerbaijan into the most important hubs of honey production in Iran. In this study, we collected samples of honey from more than 90 regions in Alborz, Zagros and Azerbaijan during the years 2020 to 2021. We evaluated the samples using melissopalynology method and measuring the amount of antioxidant activity. The rise of antioxidant activity in honey is dependent on the abundance of some plant families as well botanical origins. The abundance of plant families Rosaceae, Amaranthaceae, Fabaceae and Asteraceae showed a higher influence on the amount of antioxidants in honey than other plant families. Also, the abundance of plant families Rosaceae and Fabaceae increased with increasing altitude. In general, the amount of antioxidant activity of honey samples shows a different percentage under the influence of ecological and geographical changes.

Liver protective effect of chloroform extract of Bauhinia purpurea leaves is attributed partly to its antioxidant action and the presence of flavonoids. PHARMACEUTICAL BIOLOGY 2023; 61:1152-1161. [PMID: 37559390 PMCID: PMC10416740 DOI: 10.1080/13880209.2023.2241510] [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: 01/30/2023] [Revised: 05/29/2023] [Accepted: 07/23/2023] [Indexed: 08/11/2023]
Abstract
CONTEXT Bauhinia purpurea L. (Fabaceae) is used in the Ayurvedic system to treat various oxidative-related ailments (e.g., wounds, ulcers etc.). Therefore, it is believed that the plant also has the potential to alleviate oxidative-related liver damage. OBJECTIVE This study elucidates the hepatoprotective activity of chloroform extract of B. purpurea leaves (CEBP) in paracetamol (PCM)-induced liver injury (PILI) rats. MATERIALS AND METHODS Male Sprague-Dawley rats (n = 6) were pre-treated once daily (p.o.) with CEBP (50-500 mg/kg) for seven consecutive days before being administered (p.o.) a hepatotoxic agent, 3 g/kg PCM. Liver enzyme levels were determined from the collected blood, while the collected liver was used to determine the activity of endogenous antioxidant enzymes and for histopathological examination. CEBP was also subjected to radical scavenging assays and phytochemical analysis. RESULTS CEBP significantly (p < 0.05) reversed the toxic effect of PCM by increasing the serum levels of AST and ALT, and the activity of endogenous catalase (CAT) and superoxide dismutase (SOD) while reducing the liver weight/body weight (LW/BW) ratio. Other than low TPC value and radical scavenging activity, CEBP had a high antioxidant capacity when evaluated using the oxygen radical absorbance capacity (ORAC) assay. UHPLC-ESI-MS analysis of CEBP showed the presence of flavonoids. DISCUSSION AND CONCLUSIONS CEBP exerts its hepatoprotective activity through a non-free radical scavenging pathway that involves activation of the endogenous enzymatic antioxidant defense system. Further study is needed to identify the responsible bioactive compounds before the plant can be developed as a future alternative hepatoprotective medicament for clinical use.

Abstract
Viola L. is the largest genus of the Violaceae family with more than 500 species across the globe. The present extensive literature survey revealed Viola species to be a group of important nutritional and medicinal plants used for the ethnomedicinal treatment of noncommunicable diseases (NCDs) such as diabetes, asthma, lung diseases, and fatigue. Many plant species of this genus have also received scientific validation of their pharmacological activities including neuroprotective, immunomodulatory, anticancer, antihypertensive, antidyslipidemic, analgesic, antipyretic, diuretic, anti-inflammatory, anthelmintic, and antioxidant. Viola is highly rich in different natural products some of which have been isolated and identified in the past few decades; these include flavonoids terpenoids and phenylpropanoids of different pharmacological activities. The pharmacokinetics and clinical studies on this genus are lacking, and the present review is aimed at summarizing the current understanding of the ethnopharmacology, phytochemistry, nutritional composition, and pharmacological profile of medicinal plants from the Viola genus to reveal its therapeutic potentials, gaps, and subsequently open a new window for future pharmacological research.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2023; 2023:1901529. [PMID: 37868204 PMCID: PMC10586904 DOI: 10.1155/2023/1901529] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 07/11/2023] [Accepted: 09/19/2023] [Indexed: 10/24/2023]
Abstract
Background Free radicals are very reactive molecules produced during oxidation events that in turn initiate a chain reaction resulting in cellular damage. Many degenerative diseases in humans, including cancer and central nervous system damage, are caused by free radicals. Scientific evidence indicates that active compounds from natural products can protect cells from free radical damage. As a result, the aim of this review is to provide evidence of the use of diverse Ethiopian medicinal plants with antioxidant properties that have been scientifically validated in order to draw attention and foster further investigations in this area. Methods The keywords antioxidant, radical scavenging activities, reactive oxygen species, natural product, Ethiopian Medicinal plants, and 2, 2-Diphenyl-1-picrylhydrazyl radical scavenging assay (DPPH) were used to identify relevant data in the major electronic scientific databases, including Google Scholar, ScienceDirect, PubMed, Medline, and Science domain. All articles with descriptions that were accessed until November 2022 were included in the search strategy. Results A total of 54 plant species from 33 families were identified, along with 46 compounds isolated. More scientific studies have been conducted on plant species from the Brassicaceae (19%), Asphodelaceae (12%), and Asteraceae (12%) families. The most used solvent and extraction method for plant samples are methanol (68%) and maceration (88%). The most examined plant parts were the leaves (42%). Plant extracts (56%) as well as isolated compounds (61%) exhibited significant antioxidant potential. The most effective plant extracts from Ethiopian flora were Bersama abyssinica, Solanecio gigas, Echinops kebericho, Verbascum sinaiticum, Apium leptophyllum, and Crinum abyssinicum. The best oxidative phytochemicals were Rutin (7), Flavan-3-ol-7-O-glucoside (8), Myricitrin (13), Myricetin-3-O-arabinopyranoside (14), 7-O-Methylaloeresin A (15), 3-Hydroxyisoagatholactone (17), β-Sitosterol-3-O-β-D-glucoside (22), Microdontin A/B (24), and Caffeic acid (39). Conclusion Many crude extracts and compounds exhibited significant antioxidant activity, making them excellent candidates for the development of novel drugs. However, there is a paucity of research into the mechanisms of action as well as clinical evidence supporting some of these isolated compounds. To fully authenticate and then commercialize, further investigation and systematic analysis of these antioxidant-rich species are required.

Apigetrin-enriched Pulmeria alba extract prevents assault of STZ on pancreatic β-cells and neuronal oxidative stress with concomitant attenuation of tissue damage and suppression of inflammation in the brain of diabetic rats. Biomed Pharmacother 2023; 162:114582. [PMID: 36989727 DOI: 10.1016/j.biopha.2023.114582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 03/15/2023] [Accepted: 03/21/2023] [Indexed: 03/30/2023] Open
Abstract
In the present study, in vitro, in vivo, and in silico models were used to evaluate the therapeutic potential of Pulmeria alba methanolic (PAm) extract, and we identified the major phytocompound, apigetrin. Our in vitro studies revealed dose-dependent increased glucose uptake and inhibition of α-amylase (50% inhibitory concentration (IC50)= 217.19 µg/mL), antioxidant (DPPH, ferric-reducing activity of plasma (FRAP), and lipid peroxidation (LPO) [IC50 = 103.23, 58.72, and 114.16 µg/mL respectively]), and anti-inflammatory potential (stabilizes human red blood cell (HRBC) membranes, and inhibits proteinase and protein denaturation [IC50 = 143.73, 131.63, and 198.57 µg/mL]) by the PAm extract. In an in vivo model, PAm treatment reversed hyperglycemia and attenuated insulin deficiency in rats with streptozotocin (STZ)-induced diabetes. A post-treatment tissue analysis revealed that PAm attenuated neuronal oxidative stress, neuronal inflammation, and neuro-cognitive deficiencies. This was evidenced by increased levels of antioxidants enzymes (superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH)), and decreased malondialdehyde (MDA), proinflammatory markers (cyclooxygenase 2 (COX2), nuclear factor (NF)-κB and nitric oxide (NOx)), and acetylcholinesterase (AChE) activities in the brain of PAm-treated rats compared to the STZ-induced diabetic controls. However, no treatment-related changes were observed in levels of neurotransmitters, including serotonin and dopamine. Furthermore, STZ-induced dyslipidemia and alterations in serum biochemical markers of hepatorenal dysfunction were also reversed by PAm treatment. Extract characterization identified apigetrin (retention time: 21,227 s, 30.48%, m/z: 433.15) as the major bioactive compound in the PAm extract. Consequently, we provide in silico insights into the potential of apigetrin to target AChE/COX-2/NOX/NF-κB Altogether the present study provides preclinical evidence of the therapeutic potential of the apigetrin-enriched PAm extract for treating oxidative stress and neuro-inflammation associated with diabetes.

Abstract
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-mediated coronavirus disease 2019 (COVID-19) infection remains a global pandemic and health emergency with overwhelming social and economic impacts throughout the world. Therapeutics for COVID-19 are limited to only remdesivir; therefore, there is a need for combined, multidisciplinary efforts to develop new therapeutic molecules and explore the effectiveness of existing drugs against SARS-CoV-2. In the present study, we reported eight (SCOV-L-02, SCOV-L-09, SCOV-L-10, SCOV-L-11, SCOV-L-15, SCOV-L-18, SCOV-L-22, and SCOV-L-23) novel structurally related small-molecule derivatives of niclosamide (SCOV-L series) for their targeting potential against angiotensin-converting enzyme-2 (ACE2), type II transmembrane serine protease (TMPRSS2), and SARS-COV-2 nonstructural proteins (NSPs) including NSP5 (3CLpro), NSP3 (PLpro), and RdRp. Our correlation analysis suggested that ACE2 and TMPRSS2 modulate host immune response via regulation of immune-infiltrating cells at the site of tissue/organs entries. In addition, we identified some TMPRSS2 and ACE2 microRNAs target regulatory networks in SARS-CoV-2 infection and thus open up a new window for microRNAs-based therapy for the treatment of SARS-CoV-2 infection. Our in vitro study revealed that with the exception of SCOV-L-11 and SCOV-L-23 which were non-active, the SCOV-L series exhibited strict antiproliferative activities and non-cytotoxic effects against ACE2- and TMPRSS2-expressing cells. Our molecular docking for the analysis of receptor-ligand interactions revealed that SCOV-L series demonstrated high ligand binding efficacies (at higher levels than clinical drugs) against the ACE2, TMPRSS2, and SARS-COV-2 NSPs. SCOV-L-18, SCOV-L-15, and SCOV-L-09 were particularly found to exhibit strong binding affinities with three key SARS-CoV-2's proteins: 3CLpro, PLpro, and RdRp. These compounds bind to the several catalytic residues of the proteins, and satisfied the criteria of drug-like candidates, having good adsorption, distribution, metabolism, excretion, and toxicity (ADMET) pharmacokinetic profile. Altogether, the present study suggests the therapeutic potential of SCOV-L series for preventing and managing SARs-COV-2 infection and are currently under detailed investigation in our lab.

Mahgoob AAE, Tousson E, Abd Eldaim MA, Ullah S, Al-Sehemi AG, Algarni H, El Sayed IET. Ameliorative role of chitosan nanoparticles against silver nanoparticle-induced reproductive toxicity in male albino rats. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:17374-17383. [PMID: 36192590 DOI: 10.1007/s11356-022-23312-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Accepted: 09/23/2022] [Indexed: 06/16/2023]
Abstract
This study was designed to evaluate the protective potentials of chitosan nanoparticles (ChNPs) against silver nanoparticle (AgNP)-induced reproductive toxicity in male Wister albino rats. AgNPs, ChNPs, and AgNPs particles coated with ChNPs were characterized by using transmission electron microscope. Control rats were injected interperitoneally with 0.5% aqueous carboxymethyl cellulose. Second group was given ChNPs at a dose 300 mg/kg bwt. Third group was given AgNPs at a dose 50 mg/kg bwt. Fourth group was given AgNPs with chitosan nanoparticles simultaneously. Fifth group was given silver nanoparticles coated with chitosan nanoparticles at a dose 300 mg/kg bwt. TEM showed the formation of AgNPs with average size of 42.7 nm, ChNPs with average size of 33.3 nm, and AgNPs coated with ChNPs with average size of 48.1 nm. AgNPs significantly reduced serum levels of FSH, LH, testosterone and prolactin, sperm count, morphology index, vitality, total motility and progressive motility, the activities of catalase and superoxide dismutase, and the concentration of reduced glutathione in testicular tissues. However, it significantly increased malondialdehyde concentration in testicular tissues, sperm abnormalities, testicular tissue damages, non-progressive motility, and immotile sperms. On the contrast, ChNPs ameliorated AgNP-induced alteration in serum levels of sex hormones, spermogram, and testicular tissue's structure and functions. These results indicated that ChNPs had protective potential against AgNP-induced reproductive toxicity and ChNPs coating AgNPs had more potent protective effect than ChNPs administrated together with AgNPs.

Biochemical and tissue physiopathological evaluation of the preclinical efficacy of Solanum torvum Swartz leaves for treating oxidative impairment in rats administered a β-cell-toxicant (STZ). Biomed Pharmacother 2022; 154:113605. [PMID: 36030588 DOI: 10.1016/j.biopha.2022.113605] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 08/22/2022] [Accepted: 08/23/2022] [Indexed: 12/06/2022] Open
Abstract
The current study evaluated the protective role of Solanum torvum Swartz against diabetes-induced oxidative stress and tissue impairment in streptozotocin (STZ)-intoxicated rats. Rats with STZ (40 mg/kg intraperitoneally (i.p.))-induced diabetes were divided into five groups (n = 5) and treated with (i) normal saline, (ii) 150 mg/kg body weight (BW) of the ethanol extract of S. torvum leaf (EESTL), (ii) 300 mg/kg BW EESTL, (iv) 100 mg/kg BW metformin, and (v) 50 m/kg BW metformin + 100 mg/kg BW EESTL orally for 21 days. Our results revealed that the EESTL displayed dose-dependent ferric-reducing antioxidant power (FRAP) activity, scavenged DPPH radicals (IC50) = 13.52 ± 0.45 µg/mL), and inhibited lipid peroxidation in an in vitro models. In addition, the EESTL demonstrated dose-dependent inhibitory activity against α-amylase (IC50 =138.46 ± 3.97 µg/mL) and promoted glucose uptake across plasma membranes of yeast cells in a manner comparable to that of metformin. Interestingly, the extract demonstrated in vivo blood glucose normalization effects with concomitant increased activities of antioxidant parameters (superoxide dismutase (SOD), catalase, and reduced glutathione (GSH)) while decreasing malondialdehyde (MDA) levels when compared to untreated rats. Similarly, serum biochemical alterations, and tissues (liver, kidney, and pancreases) histopathological aberrations in untreated rats with STZ-induced diabetes were attenuated by treatment with the EESTL. Biometabolite characterization of the extract identified gallic acid (45.81 ppm), catechin (1.18 ppm), p-coumaric acid (1.43e-1 ppm), DL-proline 5-oxo-methyl ester (9.16 %, retention time (RT): 8.57 min), salicylic acid (3.26% and 7.61 min), and butylated hydroxytoluene (4.75%, RT: 10.18 min) as the major polyphenolic compounds in the plant extract. In conclusion, our study provides preclinical evidence of the antioxidant properties and oxidative stress-preventing role of S. torvum in STZ-dosed diabetic rats. Taken together, the EESTL represents a reserve of bioactive metabolites for managing diabetes and associated complications.

Large-scale transcriptomic analysis of coding and non-coding pathological biomarkers, associated with the tumor immune microenvironment of thyroid cancer and potential target therapy exploration. Front Cell Dev Biol 2022; 10:923503.

Abstract
Papillary thyroid carcinoma (PTC) is the most prevalent endocrine malignancy with a steadily increasing global incidence in recent decades. The pathogenesis of PTC is poorly understood, and the present diagnostic protocols are deficient. Thus, identifying novel prognostic biomarkers to improve our understanding of the mechanisms of pathogenesis, diagnosis, and designing therapeutic strategies for PTC is crucial. In this study, we integrated 27 PTC transcriptomic datasets and identified overlapping differentially expressed genes (DEGs) and differentially expressed microRNAs, collectively known as thyroid tumor-enriched proteins (TTEPs), and TTEmiRs, respectively. Our integrated bioinformatics analysis revealed that TTEPs were associated with tumor stages, poor surgical outcomes, distant metastasis, and worse prognoses in PTC cohorts. In addition, TTEPs were found to be associated with tumor immune infiltrating cells and immunosuppressive phenotypes of PTC. Enrichment analysis suggested the association of TTEPs with epithelial-to-mesenchymal transition (EMT), cell-matrix remodeling, and transcriptional dysregulation, while the TTEmiRs (miR-146b-5p and miR-21-5p) were associated with the modulation of the immune response, EMT, migration, cellular proliferation, and stemness. Molecular docking simulations were performed to evaluate binding affinities between TTEPs and antrocinnamomin, antcin, and antrocin, the bioactive compounds from one of the most reputable Taiwan indigenous medicinal plants (Antrodia camphorata). Our results revealed that antcin exhibited higher binding efficacies toward FN1, ETV5, and NRCAM, whereas antrocin demonstrated the least. Among the targets, fibronectin (FN1) demonstrated high ligandability potential for the compounds whereas NRCAM demonstrated the least. Collectively, our results hinted at the potential of antcin for targeting TTEPs. In conclusion, this comprehensive bioinformatics analysis strongly suggested that TTEPs and TTEmiRs could be used as potential diagnostic biomarker signatures and be exploited as potential targets for therapeutics development.

Abstract
The quest for novel anti-diabetic medication from medicinal plants is very important since they contain bioactive phytochemicals that offer better activity and safety compared to conventional therapy. In the present study, in vitro, in vivo and in silico approaches were explored to evaluate the anti-inflammatory, antioxidants, and hypoglycemic activities of the crude methanol extract of Azanza garckeana pulp. Our in vitro analysis revealed that the extract contains total phenols (260.80 ± 2.23 mg/100 g) and total flavonoids (10.28 ± 1.29 mg/100 g) contents, and demonstrated dose-dependent in vitro antioxidants activities in; DPPH (IC50 =141.30 ± 1.64 µg/mL), FRAP (IC50 =155.07 ± 1.03 µg/mL), LPO (IC50 =184.96 ± 2.01 µg/mL), and ABTS (IC50 =162.56 ± 1.14 µg/mL) assays; anti-inflammatory activities in: membrane stabilization (IC50 =141.34 ± 0.46 µg/mL), protein denaturation (IC50 =203.61 ± 2.35 µg/mL) and proteinase activities (IC50=f 171.35 ± 1.56 µg/mL) assays; and hypoglycemic activities in: α- amylase (IC50 277.85 ± 2.51 µg/mL), and glucose uptake by yeast cells assays. In vivo analysis revealed that the extract exhibited dose-dependent anti-inflammatory, hypoglycemic activities and improved the weight gain in STZ-induced diabetic rats. In addition, the extract attenuated oxidative stress and increased the activities of SOD, catalase, GSH while depleting the level of LPO in STZ induced diabetic rats. Consequently, the liquid chromatography mass spectrometry (LC-MS) characterization of A. garckeana pulp, revealed the presence of 2-Hexadecen-1-ol,3,7,11,15-tetramethyl-,(2E,7 R,11 R)-, nonyl flavanone, testolactone and 6-(Benzyloxy)- 4,4-Dimethyl-2-Chromanone. These compounds were subjected to pharmacoinformatics analysis among which testolactone and 6-(Benzyloxy)- 4,4-Dimethyl-2-Chromanone demonstrated the best drug-likeness, pharmacokinetics, and also exhibited potential hypoglycemic and anti-inflammatory properties. Altogether, the present study provides preclinical evidence of the antioxidant, anti-inflammatory and antidiabetic activities of A. garckeana extract suggesting its potential applications for the development of alternative therapy for diabetes and its associated inflammatory condition.

BIOMED RESEARCH INTERNATIONAL 2022; 2022:4122166. [PMID: 35496049 PMCID: PMC9045995 DOI: 10.1155/2022/4122166] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 03/29/2022] [Accepted: 04/05/2022] [Indexed: 02/07/2023]
Abstract
Drug-induced liver injury (DILI) is the main cause of liver damage mediated by the excretion of toxic active drug metabolites. Omega-3 fatty acids and vitamin C have potent antioxidant, anti-inflammatory, and antiapoptotic effects that could offer protection against oxidative stress and liver damage. This study evaluated the hepatoprotective effect of omega-3 and vitamin C alone as well as in a combined form in methotrexate- (MTX-) induced acute liver injury in mice. Male ICR mice of seven groups (7 mice per group) were used. Groups 1 (control group) and 2 (MTX) received 0.9% saline/day (po) for 9 days. Groups 3 and 4 received 100 and 200 mg/kg bw/day omega-3 (po), respectively, for 9 days. Groups 5 and 6 received 100 and 200 mg/kg bw/day vitamin C (po), respectively, for 9 days, while group 7 received omega-3 (100 mg/kg bw/day) and vitamin C (100 mg/kg bw/day) (po) for 9 days. All animals in groups 2 to 7 received 20 mg/kg/day MTX (I.P.) once on the 10th day. Our results revealed that MTX significantly induced the elevation of transaminases, alkaline phosphates (ALP), lactate dehydrogenase (LDH), and malonaldehyde (MDA) while depleting the levels of superoxide dismutase (SOD) and glutathione (GSH) when compared to the control group. Treatment with omega-3 fatty acids or vitamin C significantly attenuated the antioxidants and biochemical alterations in a dose-independent manner. Our molecular docking study of ligand-receptor interaction revealed that both ascorbic acid and omega-3 docked well to the binding cavity of LDH with high binding affinities of -5.20 and -4.50 kcal/mol, respectively. The histopathological features were also improved by treatment with omega-3 and vitamin C. The combined form of omega-3 and vitamin C showed a remarkable improvement in the liver enzymes, oxidative stress biomarkers, and the histopathological architecture of the mice. Conclusively, the combination of omega-3 and vitamin C demonstrated a synergistic therapeutic effect against MTX-intoxicated mice, hence representing a potential novel strategy for the management of drug-induced liver disorders.

Abstract
Cordia africana Lam (Boraginaceae) is widely used in Ethiopian folk medicine for the treatment of different types of liver disorders. Thus, this study aimed to investigate the hepatoprotective effects of an aqueous (CAAE), 80% methanol extracts of C. africana stem bark (CAME), and the solvent fractions of the methanol extract against acetaminophen (APAP)-induced liver injury in rats. Acute toxicity test and APAP-induced lethality test were done on mice of either sex, while APAP dose selection test was done on female rats. Male rats were used for hepatoprotective experiments and the liver injury was induced using 2 g/kg APAP given orally. Serum levels of the liver enzymes and total bilirubin (TB), as well as lipid profiles, were determined. Histopathological examination of the liver tissues was also conducted to confirm the findings of biochemical analysis. Intraperitoneal (i.p.) sodium pentobarbital (SPB)-induced sleeping duration was also used to determine the protective effect of the test substances. Oral administration of APAP resulted in a significant increase in serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), TB, low-density lipoprotein (LDL), total cholesterol (TC), and triglycerides (TGs) and decrease in serum high-density lipoprotein (HDL). Administration of the standard drug, silymarin 100 mg/kg, extracts at doses of 100, 200, and 400 mg/kg and fractions at the dose of 400 mg/kg reversed the serum levels of all parameters to normal. CAME exerted a significant dose-dependent hepatoprotective effect in terms of ALT and AST, while CAAE significant dose-dependent hepatoprotective effect was in terms of AST, ALP, and TGs. The protective effect of the extracts and fractions was also confirmed by histopathological investigations and SPB-induced sleeping time. From the results of the present study, it can be concluded that C. africana stem bark aqueous, 80% methanol crude extracts, and solvent fractions of the methanol extract showed hepatoprotective effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Neurodegenerative diseases are neuronal diseases that affect the brain components by degenerating the structure and function of the central or peripheral nervous system progressively. It is a leading cause of death and affects huge amount of people worldwide. Plant-based medicines have been utilised in the therapies for many illnesses that have defied western treatments, including neurodegenerative diseases. AIM OF THIS REVIEW This review presents an overview of the major neurodegenerative diseases and reported prominent medicinal plants used in managing those diseases in West Africa. METHODS Scientific articles regarding medicinal plants and their usefulness in managing neurodegenerative diseases in West Africa were pooled from different scientific databases. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses to filter articles based on their relevance. Pharmacological activity, plant parts used, experimental models, and some isolated chemical compounds of those plants were summarised. RESULTS In the West Africa region, Fabaceae (19%) and Solanaceae (13%) have the highest representation of plant families used to treat neurological diseases, while Apocynaceae, Asteraceae, Euphorbiaceae have also been utilised. Flavonoids, alkaloids, phenolic compounds, terpenoids, coumarins present in those plants and their derivatives are reported to possess neuro-protective effects. Biochemical enzymes correlating to antioxidants, anti-inflammatory effects are the potential targets against neurodegenerative diseases. CONCLUSION Medicinal plants for anti-neurodegenerative diseases in West Africa have been documented with their neuropharmacological activities. Plant families such as Fabaceae, Solanaceae, Apocynaceae, Asteraceae, and Euphorbiaceae could be a major natural source for discovery of anti-neurodegenerative drugs, thus the metabolites from them should be given priority for neurological research. This review will provide clues for further investigations on the screening and development of anti-neurodegenerative natural products from West African medicinal plants.

Identification of a Novel Theranostic Signature of Metabolic and Immune-Inflammatory Dysregulation in Myocardial Infarction, and the Potential Therapeutic Properties of Ovatodiolide, a Diterpenoid Derivative. Int J Mol Sci 2022; 23:ijms23031281. [PMID: 35163208 PMCID: PMC8836044 DOI: 10.3390/ijms23031281] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 01/18/2022] [Accepted: 01/21/2022] [Indexed: 01/27/2023] Open
Abstract
Myocardial infarction (MI) is a multifactorial global disease, recognized as one of the leading causes of cardiovascular morbidity and mortality. Timely and correct diagnoses and effective treatments could significantly reduce incidence of complications and improve patient prognoses. In this study, seven unconventional differentially expressed genes (DEGs) (MAN2A2, TNFRSF12A, SPP1, CSNK1D, PLAUR, PFKFB3, and CXCL16, collectively termed the MTSCPPC signature) were identified through integrating DEGs from six MI microarray datasets. The pathological and theranostic roles of the MTSCPPC signature in MI were subsequently analyzed. We evaluated interactions of the MTSCPPC signature with ovatodiolide, a bioactive compound isolated from Anisomeles indica (L.) Kuntze, using in silico molecular docking tools and compared it to specific inhibitors of the members of the MTSCPPC signature. Single-cell transcriptomic analysis of the public databases revealed high expression levels of the MTSCPPC signature in immune cells of adult human hearts during an MI event. The MTSCPPC signature was significantly associated with the cytokine–cytokine receptor interactions, chemokine signaling, immune and inflammatory responses, and metabolic dysregulation in MI. Analysis of a micro (mi)RNA regulatory network of the MTSCPPC signature suggested post-transcriptional activation and the roles of miRNAs in the pathology of MI. Our molecular docking analysis suggested a higher potential for ovatodiolide to target MAN2A2, CSNK1D, and TNFRSF12A. Collectively, the results derived from the present study further advance our understanding of the complex regulatory mechanisms of MI and provide a potential MI theranostic signature with ovatodiolide as a therapeutic candidate.

Sterculia tragacantha Lindl Leaf Extract Ameliorates STZ-Induced Diabetes, Oxidative Stress, Inflammation and Neuronal Impairment. J Inflamm Res 2021; 14:6749-6764. [PMID: 34916823 PMCID: PMC8668250 DOI: 10.2147/jir.s319673] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 11/17/2021] [Indexed: 12/13/2022] Open
Abstract
Background Sterculia tragacantha is a medicinal plant commonly used in the western part of Nigeria, for managing diabetes mellitus. However, there is a dearth of scientific information on the antidiabetic and neuroprotective properties of the plant. Methods The in silico, in vitro and in vivo models were used to evaluate the antioxidants, antidiabetic, anti-inflammatory and neuroprotective potential of aqueous extract of Sterculia tragacantha leaf (AESTL) in streptozotocin (STZ)-induced diabetic rats. Thirty (30) male albino rats (155.34±6.33 g) were intraperitoneal injected with 40 mg/kg of freshly prepared streptozotocin and were divided into 5 groups (A-E) of 6 animals each. Groups A–D were treated with 0, 150 and 300 mg/kg of AESTL, and 200 mg/kg body weight of metformin respectively, while group E serve as the normal control. Results The results of in vitro analysis revealed dose-dependent antioxidant activities; ABTS (IC50 = 63.03±2.57 μg/mL), DPPH (117.49±2.35 μg/mL), FRAP (15.19±0.98 mmol/100g), TAC (43.38±0.96 mg/100g), hypoglycaemic effect; α-amylase (IC50 = 77.21±4.35 μg/mL) and α-glucosidase (IC50 = 443.25±12.35), and anti-cholinesterase; AChE (IC50 = 113.07±3.42 μg/mL) and BChE (IC50 = 87.50±4.32 μg/mL) activities of AESTL. In vivo study revealed dose-dependent hypoglycemic effect and body weight improvement in rats treated with the AESTL. In addition, AESTL improved the antioxidant status and attenuated STZ-induced dysregulations of Na+-K+-ATPase, cholinesterases and neurotransmitters in the brain tissue of experimental rats. The results also demonstrated that AESTL could regulate anti-inflammatory response via inhibition of COX-2/NO signaling axis in the brain of diabetic rats. Molecular docking analysis revealed that epicatechin and procyanidin B2, the bioactive compounds from AESTL, docked well to the binding cavities of acetylcholinesterase, butyrylcholinesterase, α-amylase and α-glucosidase with binding affinities ranges between –8.0 and –11.4 kcal/mol, suggesting that these compounds are the bioactive component that could be responsible for the antidiabetic and neuroprotective activities of AESTL. Conclusion The results of the present study strongly suggested that the AESTL extract could be very useful for halting diabetes progression and its associated neuroinflammation complications.

Glyphaeaside C- enriched extract of Glyphaea brevis restored the antioxidant and reproductive integrity of 1,4-Dinitrobenzene-intoxicated rats. Biomed Pharmacother 2021; 145:112359. [PMID: 34887141 DOI: 10.1016/j.biopha.2021.112359] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 10/15/2021] [Accepted: 10/19/2021] [Indexed: 01/10/2023] Open
Abstract
This study assessed the fertility potential of methanol leaf extract of Glyphaea brevis (MGB) in rats exposed to 1,4-Dinitrobenzene (DNB), an environmental reprotoxicant. Male Wistar rats were orally exposed to 50 mg/kg DNB and administered 750 mg/kg MGB, 1500 mg/kg MGB or 300 mg/kg vitamin E for 21 days after 48 h of DNB exposure. Determination of serum reproductive hormone levels by enzyme-linked immunosorbent assays, evaluation of hematologic profile, computer-assisted sperm analyses (CASA) of sperm kinematics and morphology, assessment of testicular and spermatozoan antioxidant systems, and histopathological evaluation of reproductive tissues were performed. HPLC-DAD analysis identify Glyphaeaside C as the major component of the extract. In rats toxified with 50 mg/kg DNB, testicular and epididymal weights, serum levels of luteinizing hormone, testosterone and follicle-stimulating hormone, and packed cell volume, haemoglobin concentration, and white blood cell counts were decreased. There was altered sperm kinematics which reflected in increased sperm abnormalities. Treatment with the Glyphaeaside C -enriched MGB counteracted all DNB-induced changes and corrected DNB-induced aberrations in kinematic endpoints. Also, testicular and epididymal antioxidant systems were disrupted and there was damage to tissue histoarchitecture. Furthermore, our molecular docking study revealed that Glyphaeaside-C exhibited high binding affinities to the binding pocket of some free radical generating enzymes. Conclusively, the results indicated that Glyphaeaside C-enriched extract of Glyphaea brevis leaf enhanced the quality of semen and improved the functional capabilities of spermatozoa following exposure of rats to DNB which could translate to enhanced fertility.

Identification of NSP3 ( SH2D3C) as a Prognostic Biomarker of Tumor Progression and Immune Evasion for Lung Cancer and Evaluation of Organosulfur Compounds from Allium sativum L. as Therapeutic Candidates. Biomedicines 2021; 9:1582. [PMID: 34829812 PMCID: PMC8615911 DOI: 10.3390/biomedicines9111582] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 10/26/2021] [Accepted: 10/27/2021] [Indexed: 12/21/2022] Open
Abstract
The multi-domain non-structural protein 3 (NSP3) is an oncogenic molecule that has been concomitantly implicated in the progression of coronavirus infection. However, its oncological role in lung cancer and whether it plays a role in modulating the tumor immune microenvironment is not properly understood. In the present in silico study, we demonstrated that NSP3 (SH2D3C) is associated with advanced stage and poor prognoses of lung cancer cohorts. Genetic alterations of NSP3 (SH2D3C) co-occurred inversely with Epidermal Growth Factor Receptor (EGFR) alterations and elicited its pathological role via modulation of various components of the immune and inflammatory pathways in lung cancer. Our correlation analysis suggested that NSP3 (SH2D3C) promotes tumor immune evasion via dysfunctional T-cell phenotypes and T-cell exclusion mechanisms in lung cancer patients. NSP3 (SH2D3C) demonstrated a high predictive value and association with therapy resistance in lung cancer, hence serving as an attractive target for therapy exploration. We evaluated the in silico drug-likeness and NSP3 (SH2D3C) target efficacy of six organosulfur small molecules from Allium sativum using a molecular docking study. We found that the six organosulfur compounds demonstrated selective cytotoxic potential against cancer cell lines and good predictions for ADMET properties, drug-likeness, and safety profile. E-ajoene, alliin, diallyl sulfide, 2-vinyl-4H-1,3-dithiin, allicin, and S-allyl-cysteine docked well into the NSP3 (SH2D3C)-binding cavity with binding affinities ranging from -4.3~-6.70 Ă and random forest (RF) scores ranging from 4.31~5.26 pKd. However, S-allyl-cysteine interaction with NSP3 (SH2D3C) is unfavorable and hence less susceptible to NSP3 ligandability. In conclusion, our study revealed that NSP3 is an important onco-immunological biomarker encompassing the tumor microenvironment, disease staging and prognosis in lung cancer and could serve as an attractive target for cancer therapy. The organosulfur compounds from A. sativum have molecular properties to efficiently interact with the binding site of NSP3 and are currently under vigorous preclinical study in our laboratory.

Abstract
Alzheimer’s disease (AD) is the most frequent cause of neurodegenerative dementia and affects nearly 50 million people worldwide. Early stage diagnosis of AD is challenging, and there is presently no effective treatment for AD. The specific genetic alterations and pathological mechanisms of the development and progression of dementia remain poorly understood. Therefore, identifying essential genes and molecular pathways that are associated with this disease’s pathogenesis will help uncover potential treatments. In an attempt to achieve a more comprehensive understanding of the molecular pathogenesis of AD, we integrated the differentially expressed genes (DEGs) from six microarray datasets of AD patients and controls. We identified ATPase H+ transporting V1 subunit A (ATP6V1A), BCL2 interacting protein 3 (BNIP3), calmodulin-dependent protein kinase IV (CAMK4), TOR signaling pathway regulator-like (TIPRL), and the translocase of outer mitochondrial membrane 70 (TOMM70) as upregulated DEGs common to the five datasets. Our analyses revealed that these genes exhibited brain-specific gene co-expression clustering with OPA1, ITFG1, OXCT1, ATP2A2, MAPK1, CDK14, MAP2K4, YWHAB, PARK2, CMAS, HSPA12A, and RGS17. Taking the mean relative expression levels of this geneset in different brain regions into account, we found that the frontal cortex (BA9) exhibited significantly (p < 0.05) higher expression levels of these DEGs, while the hippocampus exhibited the lowest levels. These DEGs are associated with mitochondrial dysfunction, inflammation processes, and various pathways involved in the pathogenesis of AD. Finally, our blood–brain barrier (BBB) predictions using the support vector machine (SVM) and LiCABEDS algorithm and molecular docking analysis suggested that antrocin is permeable to the BBB and exhibits robust ligand–receptor interactions with high binding affinities to CAMK4, TOMM70, and T1PRL. Our results also revealed good predictions for ADMET properties, drug-likeness, adherence to Lipinskís rules, and no alerts for pan-assay interference compounds (PAINS) Conclusions: These results suggest a new molecular signature for AD parthenogenesis and antrocin as a potential therapeutic agent. Further investigation is warranted.

Abstract
Ischemia-reperfusion injury is a urological emergency condition that could lead to necrosis, testicular damage subfertility, and infertility. The purpose of this study was to identify changes taking place in the rat testis at short-term (4 hr) as well as long-term (7 days) reperfusion following testicular torsion and to evaluate the effects of Proxeed Plus (PP), L-carnitine-rich antioxidant supplement, on preventing these changes using the biochemical parameters and histopathology. Thirty adult male rats were divided into five groups: in groups, 1-4 testicular ischemia was achieved by rotating the left testis 720° clockwise for 4 h and dividing into the sham, torsion/detorsion (T/D), T/D+1000 mg/kg BW PP, and T/D+5000 mg/kg BW PP groups, respectively. PP was administered intraperitoneally 30 min before detorsion while group 5 served as the normal control. All rats were sacrificed 4 h after detorsion. The same experimental design was set up, and animals were sacrificed after 7 days of detorsion. The testicular levels of human cyclooxygenase-2; tumor necrosis factor; interleukins-1β, 6, and 10; hydrogen peroxide; malonaldehyde; superoxide dismutase; catalase; glutathione transferase; glutathione peroxidase; glutathione reductase; and histopathological damage were evaluated. Our results revealed that rats in the torsion/detorsion group exhibited elevated testicular levels of oxidative markers and proinflammatory cytokines, low levels of antioxidant enzymes, and severe histological alterations relative to the control and sham groups. Treatments with 1000 and 5000 mg/kg BW of PP for 4 hr and 7 days significantly (p < 0.05) decreased the levels of the proinflammatory and oxidative markers while increasing the spermatogenesis, testicular levels of antioxidant enzymes, and anti-inflammatory cytokine (IL-10) in a dose-dependent manner. This suggested that PP exhibited anti-inflammatory and antioxidant activities against I/R testes thus serving as an effective supplement to protect against testicular assault.

Abstract
Testicular torsion is an acute urological emergency condition that occurs due to obstruction of blood flow to the testicles which may result in ischemia and loss of testicular functions. This study examined the protective effects of Proxeed Plus (PP), a dietary supplement on testicular ischemia/reperfusion (I/R) injured rats using oxidative stress markers, hormonal levels, apoptotic parameters, histological and immunohistochemistry analysis at 4 h and after 7 days of reperfusion. The protective treatment of the I/R injured rats with PP at 1000 and 5000 mg/kg body weight (bw) resulted in significant increases in the serum and tissue antioxidative defense capacities (superoxide dismutase, reduced glutathione, catalase, glutathione-s-transferase, and glutathione peroxidase), sex hormones (luteinizing hormone, follicle-stimulating hormone, and testosterone), also reduce pro-oxidative markers (malondialdehyde and hydrogen peroxide), serum iNOS and apoptotic parameters (Caspase -3 and Caspase -9) in comparison to the results detected in the I/R untreated rats. It was also observed that PP ameliorated histological changes of I/R injured rats; increased spermatogenetic activity, seminiferous tubular diameter, Leydig cell mass, and reduced expressions of testicular inducible nitric oxide synthase (iNOS). Therefore, the therapeutic use of Proxeed Plus could be considered a promising approach in averting testicular damage against I/R injury.

The purified fraction of M. senegalensis leaf shows dose dependent antiplasmodial activity with percentage curative effects of 15.24 ± 0.89, 45.70 ± 3.43 and 48.50 ± 4.56 at 75, 150 and 300 mg/kg bw against Plasmodium chabaudi and % curative effects of 44.25 ± 3.21, 72.74 ± 6.54 and 76.30 ± 8.32 respectively against Plasmodium berghei. The purified fraction exhibited 53.16 ± 4.09 and 60.76 ± 7.54 anti-inflammatory effect, 43.35 ± 4.98% and 44.83 ± 3.86% analgesic effect at 75 and 150 mg/kg bw respectively. GC-MS analysis confirmed the presence of 20α)-3-hydroxy-2-oxo-24-nor-friedela-1(10),3,5,7-tetraen-carboxylic acid-(29)-methylester, 2(4H)-Benzofuranone, 5,6,7,7a-tetrahydro- and 3-hydroxy-20(29)-lupen-28-ol and a terpenes (phytol) as the major antimalarial compounds in the fraction. The purified fraction increases the serum total proteins and transaminases concentrations but had no effect on serum levels of sodium, potassium, chloride, alkaline phosphatase, triglyceride and glucose in the mice.
Conclusion
The purified fraction of M. senegalensis leaf exhibited promising antimalarial, analgesic and anti-inflammatory activities. Thus, could serve as a template for the synthesis of new drug.

Abstract
Abstract
Background
Chemotherapy is the most widely used means of controlling trypanosomosis, however, effectiveness of the drugs available is limited by a number of factors. This study investigates the oxidative stress profile of aqueous extract of the fruit pulp of Adansonia digitata on some organs in rats infected with Trypanosoma brucei brucei.
Methods
Thirty-five male albino rats were divided into 7 groups of 5 rats each. Groups B, C, D, E, F and G were inoculated with 0.20 ml of suspension containing 106 T. b. brucei. Group A were neither infected nor treated. Group B were infected but not treated. At onset of parasitaemia, rats in group C were treated with diminazene aceturate at 3.5 mg/kg body weight once, while rats in group D were treated with vitamin C at 200 mg/kg body weight for 3 days consecutively. Rats in groups E, F and G were treated orally for 3 days with the aqueous extract of fruit pulp of A. digitata at a dosage of 40 mg/kg, 80 mg/kg and 160 mg/kg body weight respectively. Liver and kidney tissues of the rats were collected at necropsy (10 days PI) for oxidative stress analysis.
Results
There was a significant (p < 0.05) effect in the concentration levels of malondialdehyde, superoxide dismutase, glutathione peroxidase and catalase among the different groups treated with aqueous extract of fruit pulp of A. digitata.
Conclusion
The extract of A. digitata exert protective effects against tissue peroxidation in albino rats experimentally infected with T. b. brucei.

Abstract
BACKGROUND AND AIM Many natural products worldwide are used for medicinal purposes. Various insect-isolated compounds were investigated in pursuit of new therapeutic agents. This study aimed to compare the effects of methanol extract of hemolymph of Sarcophaga argyrostoma larvae with diminazene aceturate on some hematological and biochemical indices of mice infected with Trypanosoma evansi. MATERIALS AND METHODS Sixteen albino mice were randomly divided into four groups, of four mice, which received different treatments: In Group 1 (G1), mice were infected intraperitoneally with 1×104 T. evansi and received no treatment (positive control), in Group 2 (G2), infected mice were treated with 0.5 mL/kg of diminazene aceturate, in Group 3 (G3), infected mice were treated with 0.5 mL/kg methanol extract of the hemolymph of S. argyrostoma larvae, and in Group 4 (G4), uninfected mice received 0.5 ml of distilled water (negative control). In G3, treatment was started 3 days before injecting the parasite, while for the other groups, a single dose of treatment was applied when the parasite appeared in the blood. RESULTS Mice from G3 showed low parasitemia of 29×104/mm3 4 days post-infection until the infection completely disappeared on the 5th day, which was earlier than for other groups. The results showed that the numbers of red blood corpuscles (red blood cells [RBCs]) and white blood cells (WBCs) per unit volume were significantly different (p<0.05) between the four groups. The highest RBC (9.09×103 cell/ mm3) and WBC (14.30×103 cell/ mm3) counts were recorded in G3, whereas the lowest values of 6.60 and 4.60×103cell/ mm3, respectively, were recorded for G2. In addition, there were significant differences (p<0.05) between the different groups for platelet counts per unit volume, with G3 having the most (943×103 cell/ mm3) and G2 having the least (357×103 cell/ mm3). There was a significant (p<0.05) difference in the indices of biochemical activities between the extract-treated infected groups and the standard drug-treated group. CONCLUSION This study suggests that the methanol extract of the hemolymph of S. argyrostoma larva exhibits trypanocidal activity, so it may be exploited as a suitable candidate for the development of trypanocidal drugs.

Abstract
The incidence of liver diseases is increasing globally, and many patients in developing countries are resorting to the use of herbal products as treatment. This study was aimed at establishing the safety and effectiveness outcomes for patients with deranged liver panel treated with a Ghanaian finished polyherbal product. The product Heptonica is prepared by CPMR from three medicinal plants: Bidens pilosa, Citrus aurantifolia, and Trema orientalis. Fifty (50) participants with clinical and biochemical signs of liver impairment were purposively recruited and treated for a period of 28 days. Participants received Heptonica at a dose of 30 mL 8 hourly after meals for the treatment period. Clinical and biochemical evaluation (liver panel test, renal function test, haematology, and urinalysis) of subjects for the safety and effectiveness of the product was undertaken at days 0 (baseline), 14, and 28. Compared to the baseline values, Heptonica did not have any untoward effect on renal function, haematological parameters, and urine parameters of subjects. Clinical and liver panel results of the participants also improved compared to the baseline: serum aspartate transaminase (AST) (p < 0.0001), alanine transaminase (ALT) (p < 0.0001), gamma-glutamyltransferase (GGT) (p- 0.0013), total bilirubin (p-0.0136), direct bilirubin (p < 0.0001), total proteins (p-0.0409), and alkaline phosphates (p- 0.0284). Level of albumin showed no significant difference within the study period. The outcome of this study indicates Heptonica has hepatorestorative action with no observable toxicity and can be used with confidence as indicated as a liver tonic.

Antimalarial Activity of Cordia africana (Lam.) (Boraginaceae) Leaf Extracts and Solvent Fractions in Plasmodium berghei-Infected Mice. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:8324596. [PMID: 31531119 PMCID: PMC6721471 DOI: 10.1155/2019/8324596] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 07/22/2019] [Indexed: 01/08/2023]
Abstract
Background Malaria remains a major worldwide public health problem leading to death of millions of people. Spread and emergence of antimalarial drug resistance are the major challenge in malaria control. Medicinal plants are the key source of new effective antimalarial agents. Cordia africana (Lam.) is widely used for traditional management of malaria by local people in different parts of Ethiopia. The present study aimed to evaluate in vivo antimalarial effects of leaf extracts and solvent fractions of Cordia africana on Plasmodium berghei-infected mice. Methods The leaf extracts were prepared and tested for oral acute toxicity according to the OECD guideline. In vivo antimalarial effects of various doses of C. africana extracts and solvent fractions were determined using the four-day suppression test (both crude and fractions), as well as curative and chemoprophylactic tests (crude extracts). Results The acute toxicity test of the plant extract revealed that the medium lethal dose is higher than 2000 mg/kg. The crude extract of the plant exhibited significant parasitemia suppression in the four-day suppression (51.19%), curative (57.14%), and prophylactic (46.48%) tests at 600 mg/kg. The n-butanol fraction exhibited the highest chemosuppression (55.62%) at 400 mg/kg, followed by the chloroform fraction (45.04%) at the same dose. Conclusion Our findings indicated that both the crude leaf extracts and fractions of C. africana possess antimalarial effects, supporting the traditional claim of the plant.

Abstract
The global burden of heavy metal especially mercury, arsenic, lead, and cadmium toxicities remains a significant public health challenge. Developing nations are particularly at high risk and carry the highest burden of this hazard. Chelation therapy has been the mainstay for treatment of heavy metal poisoning where the chelating agent binds metal ions to form complex ring-like structures called "chelates" to enhance their elimination from the body. Metal chelators have some drawbacks such as redistribution of some heavy metals from other tissues to the brain thereby increasing its neurotoxicity, causing loss of essential metals such as copper and zinc as well as some serious adverse effects, e.g., hepatotoxicity. The use of natural antidotes, which are easily available, affordable, and with little or no side effects compared to the classic metal chelators, is the focus of this review and suggested as cheaper options for developing nations in the treatment of heavy metal poisoning.
