Abstract
Launaea fragilis (Asso) Pau is a Cholistan desert medicinal plant. Launaea species are used as traditional remedies against various inflammatory conditions. The current research was designed to evaluate the anti-nociceptive, anti-inflammatory, and anti-arthritic potential of ethanolic extract of L. fragilis (Et-LF). The plant extract was prepared by triple maceration. GC-MS screening explored the presence of various bioactive phytoconstituents including n-tetracosanol-1, 1-heptacosanol, and n-hexadecanoic acid. DPPH assay demonstrated the antioxidant potential of Et-LF. Safety profile data indicated that Et-LF was safe up to the oral dose of 5000 mg/kg in female rats. Anti-nociceptive activity of Et-LF was assessed in hot plate method and acetic acid-induced writhing model and the results suggested that Et-LF had significant analgesic effects in both animal models. Carrageenan, histamine, and serotonin-induced edema models were used to estimate the anti-inflammatory effects of Et-LF and were found to prevent paw edema development dose dependently. The anti-arthritic effect of Et-LF was estimated in CFA-induced arthritic rat model. Treatment with Et-LF 125, 250, 500 and flurbiprofen (FP) 10 mg/kg/day significantly attenuated the paw edema, reversed the reduced body weight, and restored the altered hematological parameters in arthritic rats. Gene expression studies revealed the significant downregulation of IL-1β, TNF-α, IL-6, NF‑κB, and COX-2, and upregulation of IL-4 and IL-10 in arthritic rats treated with various doses of plant extract. Histological evaluation of ankle joints showed that Et-LF mitigated pannus formation, infiltration of inflammatory cells, and fibrous connective tissue formation in the diseased rats. Thereof, it may be concluded that the recent study demonstrated the anti-nociceptive, anti-inflammatory, and anti-arthritic effects ascribed to the signifying presence of phytoconstituents in L. fragilis.

Protective Action Mechanisms of Launaea mucronata Extract and Its Nano-Formulation against Nephrotoxicity in Rats as Revealed via Biochemical, Histopathological, and UPLC-QTOF-MS/MS Analyses. Metabolites 2023; 13:786. [PMID: 37512493 PMCID: PMC10384424 DOI: 10.3390/metabo13070786] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 06/16/2023] [Accepted: 06/20/2023] [Indexed: 07/30/2023] Open
Abstract
Plants belonging to the Launaea genus have been extensively utilized ethnopharmacologically to treat a variety of diseases, including kidney disorders. Chromium is a common industrial pollutant that has been linked to kidney disease. The present work was designed for the investigation of the UPLC-QTOF-MS/MS metabolite profile of the L. mucronate ethanolic extract (LME), along with assessing the mechanistic protective actions of LME and its nano-silver formulation (LMNS) against K2Cr2O7-induced nephrotoxicity in rats. LMNE was successfully biosynthesized and confirmed using UV-Visible (UV-Vis) spectroscopy and transmission electron microscopy (TEM). The nephroprotective effects of LME and LMNE was assessed in rats exposed to potassium dichromate (K2Cr2O7, 15 mg/kg BW) to cause nephrotoxicity. LME and LMNS, separately, were administered twice daily for 14 days at doses of 200 and 400 mg/kg BW, respectively. The kidney function, catalase, UGT, Nrf2, PGE2, Cox-2, ERK, and MAPK levels in renal tissue were all assessed, along with histopathological examinations for exploring their ameliorative effects. Forty-five bioactive metabolites were annotated belonging to flavonoids, phenolic and organic acids, coumarins, and fatty acids. Metabolite profiling revealed that chlorogenic acid, apigenin, and luteolin glycosides were the main phenolics, with chlorogenic acid-O-hexoside reported for the first time in LME. The findings revealed that the serum kidney function indicators (urea and creatinine) were markedly elevated in K2Cr2O7-intoxicated rats. Furthermore, inflammatory indicators (COX-2 and PGE2), MAPK, and ERK were all markedly elevated in kidney tissue, whereas catalase, UGT, and Nrf2 levels were downregulated. Histological and immunohistochemical assays confirmed the toxic effects of K2Cr2O7 in the kidneys. In contrast, the administration of LME and LMNS prior to K2Cr2O7 considerably improved the architecture of the renal tissue, while also restoring levels of most biochemical markers. Functioning via the inhibition of the MAPK/ERK pathway, activating Nrf2, and modifying the antioxidant and metabolic enzymes, LME and LMNS exerted their nephroprotective effects against K2Cr2O7-induced toxicity.

Abstract
Inflammation is the core contributor in the pathogenesis of various acute and chronic illness including appendicitis, bronchitis, arthritis, cancer and neurological diseases. NSAIDs, commonly used medications for inflammatory diseases, on prolonged use cause GI bleeding, ulcers and many more issues. Plant-based therapeutic agents including essential oils in combination with low-dose synthetic drugs have been shown to produce synergistic effects and reduce complications of synthetic drugs. This study was designed to evaluate the anti-inflammatory, analgesic and anti-pyretic properties of Eucalyptus globulus essential oil alone and in combination with flurbiprofen. GC-MS analysis was performed to screen chemical composition of oil. In vitro anti-inflammatory assay (membrane stabilization assay) and in vivo inflammatory acute (carrageenan and histamine-induced paw oedema) and chronic (cotton pellet-induced granuloma and Complete Freund's adjuvant-induced arthritis) models were performed to check anti-inflammatory properties. Acetic acid-induced algesia and yeast-induced pyrexia models were performed to check analgesic and anti-pyretic properties. qRT-PCR was performed to study the effect of treatments on the expression of inflammatory biomarkers. GC-MS analysis of E. globulus essential oil showed the presence of eucalyptol along with other active biomolecules. 500 + 10 mg/kg of oil-drug combination showed significantly (p < 0.05) better in vitro membrane stabilization effects as compared with groups treated with 500 mg/kg of E. globulus oil and 10 mg/kg of Flurbiprofen alone. 500 + 10 mg/kg of oil-drug combination showed significantly (p < 0.05) better anti-inflammatory, analgesic and antipyretic effects as compared to 500 mg/kg of E. globulus oil alone in all in vivo models. When comparison was done between 500 + 10 mg/kg of oil-drug combination-treated and 10 mg/kg Flurbiprofen-treated group, the former group showed significantly (p < 0.05) better anti-inflammatory and anti-pyretic effects, but there were non-significant differences in the analgesic model. Animal group treated with 10 mg/kg of Flurbiprofen showed significantly (p < 0.05) better anti-inflammatory and analgesic effects than group treated with 500 mg/kg of oil alone while, there were non-significant differences in anti-pyretic effects. qRT-PCR analysis showed significant (p < 0.05) down-regulation in the expression of IL-4 and TNF-α in serum samples of animals treated with 500 + 10 mg/kg of oil-drug combination as compared to the diseased control (arthritic) group. Overall, the current research demonstrates that Eucalyptus globulus essential oil in combination with flurbiprofen showed better anti-inflammatory, analgesic and anti-pyretic effects than oil and flurbiprofen alone which is attributed to the down-regulation of pro-inflammatory biomarkers (IL-4 and TNF-α). Further studies are required to formulate a stable dosage form and to check the anti-inflammatory efficacy in different inflammatory disorders.

J Exp Pharmacol 2023; 15:63-79. [PMID: 36864852 PMCID: PMC9970881 DOI: 10.2147/jep.s396769] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 02/15/2023] [Indexed: 02/24/2023] Open
Abstract
Background Ethnobotanical studies in various districts of Ethiopia reported that Ehretia cymosa (E. cymosa) is used for the management of headache, abdominal pain, arthritis and rheumatism. However, there is no scientific investigation done so far to confirm these traditional claims. Thus, the aim of this study was to assess the analgesic and anti-inflammatory effects of the 80% methanol extract and fractions of E. cymosa leaves. Methods The dried and pulverized leaves of E. cymosa were soaked with 80% methanol to obtain a crude extract. Fractionation was done using chloroform, ethyl acetate and water by a soxhlet apparatus. The analgesic effects of the crude extract and solvent fractions were assessed using acetic acid-induced writhing and hot plate tests whereas anti-inflammatory activities were investigated using carrageenan-induced paw edema and cotton-pellet-induced granuloma models. Results In all the tested doses, the 80% methanol extract and solvent fractions revealed substantial (p < 0.001) analgesic activities in acetic acid induced writhing test. In the hot plate method, all the tested doses of E. cymosa crude extract and the solvent fractions produced significant analgesic activities (p < 0.05). In the carrageenan-induced acute inflammation model, all tested doses of the crude extract and solvent fractions resulted in a significant decline in paw edema. The 80% methanol extract and solvent fractions of E. cymosa at all the tested doses significantly reduced inflammatory exudates and granuloma mass formations (p < 0.001). Conclusion From the results of this investigation, it can be stated that 80% methanol extract, aqueous, ethyl acetate and chloroform fractions of E. cymosa exhibited considerable analgesic and anti-inflammatory activities, supporting the plant's traditional use as a remedy for a variety of painful and inflammatory conditions.

Wound Healing and Antioxidant Properties of Launaea procumbens Supported by Metabolomic Profiling and Molecular Docking. Antioxidants (Basel) 2022; 11:antiox11112258. [PMID: 36421445 PMCID: PMC9687060 DOI: 10.3390/antiox11112258] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 11/10/2022] [Accepted: 11/10/2022] [Indexed: 11/18/2022] Open
Abstract
Wounds adversely affect people’s quality of life and have psychological, social, and economic impacts. Herbal remedies of Launaea procumbens (LP) are used to treat wounds. In an excision wound model, topical application of LP significantly promoted wound closure (on day 14, LP-treated animals had the highest percentages of wound closure in comparison with the other groups, as the wound was entirely closed with a closure percentage of 100%, p < 0.05). Histological analysis revealed a considerable rise in the number of fibroblasts, the amount of collagen, and its cross-linking in LP-treated wounds. Gene expression patterns showed significant elevation of TGF-β levels (2.1-fold change after 7 days treatment and 2.7-fold change in 14 days treatment) and downregulation of the inflammatory TNF-α and IL-1β levels in LP-treated wounds. Regarding in vitro antioxidant activity, LP extract significantly diminished the formation of H2O2 radical (IC50 = 171.6 μg/mL) and scavenged the superoxide radical (IC50 of 286.7 µg/mL), indicating antioxidant potential in a dose-dependent manner. Dereplication of the secondary metabolites using LC-HRMS resulted in the annotation of 16 metabolites. The identified compounds were docked against important wound-healing targets, including vascular endothelial growth factor (VEGF), collagen α-1, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and transforming growth factor-β (TGF-β). Among dereplicated compounds, luteolin 8-C-glucoside (orientin) demonstrated binding potential to four investigated targets (VEGF, interleukin 1β, TNF-α, and collagen α-1). To conclude, Launaea procumbens extract could be regarded as a promising topical therapy to promote wound healing in excisional wounds, and luteolin 8-C-glucoside (orientin), one of its constituents, is a potential wound-healing drug lead.

Abstract
Taraxacum officinale (TO) has been historically used for medicinal purposes due to its biological activity against specific disorders. To investigate the antioxidant and the antiproliferativepotential of TO essential oil in vitro and in vivo, the chemical composition of the essential oil was analyzed by GC-MS. The in vivo antioxidant capacity was assessed on liver and kidney homogenate samples from mice subjected to acetaminophen-induced oxidative stress and treated with TO essential oil (600 and 12,000 mg/kg BW) for 14 days. The in vitro scavenging activity was assayed using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and the reducing power methods. The cytotoxic effects against the HeLa cancer cell line were analyzed. The GC-MS analysis showed the presence of 34 compounds, 8 of which were identified as major constituents. The TO essential oil protected mice’s liver and kidneys from acetaminophen-induced oxidative stress by enhancing antioxidant enzymes (catalase, superoxide dismutase, and glutathione) and lowering malondialdehyde levels. In vitro, the TO essential oil demonstrated low scavenging activity against DPPH (IC50 = 2.00 ± 0.05 mg/mL) and modest reducing power (EC50 = 0.963 ± 0.006 mg/mL). The growth of the HeLa cells was also reduced by the TO essential oil with an inhibition rate of 83.58% at 95 µg/mL. Current results reveal significant antioxidant and antiproliferative effects in a dose-dependent manner and suggest that Taraxacum officinale essential oil could be useful in formulations for cancer therapy.

Abstract
Background: Inflammation is a strong reaction of the non-specific natural immune system that helps to start protective responses against encroaching pathogens and develop typical immunity against intruding factors. However, prolonged inflammation may lead to chronic autoimmune diseases. For thousands of years, medicinal plants have served as an excellent source of treatment for chronic pathologies such as metabolic diseases. Purpose: The present study aims to evaluate the anti-inflammatory and anti-angiogenic potential of Moringa olifera Lam. extract (MO) and Moringa-loaded nanoclay films. Methods: The extract preparation was done through the maceration technique using absolute methanol (99.7%) and labelled as Mo. Me. Mo. Me-loaded nanoclay-based films were prepared by using pectin and sericin (Table 1). The in vitro studies characterized the film thickness, moisture, and phytochemical contents. The in vivo anti-inflammatory tests involved using a cotton pellet-induced granuloma model assay. In addition, the chick chorioallantoic membrane (CAM) assay was employed for angiogenesis activity. Results: The phytochemical analysis of the extract confirmed the presence of alkaloids, glycosides, flavonoids and phytosterol. This extract contained quercetin in a large quantity. Cotton-pellet induced granuloma model study revealed a comparable (p > 0.05) effect of a high dose of Mo. Me (500 mg/kg) as compared with standard drug. Noteworthy, data obtained through the RT-PCR technique manifested the dose-dependent anti-oedematous effect of Moringa olifera via downregulation of TNF-α and interleukin-1ß. The findings of the CAM assay exhibited a remarkable anti-angiogenic activity of Mo. Me loaded nanoclay films, showing diffused vasculature network in the macroscopic snapshot. Conclusion:Moringa olifera and its nanocomposite films have therapeutic potential against inflammation.

Abstract
Melilotus indicus (L.) All. is known to have anti-inflammatory and anticancer properties. The present study explored the in vivo skin carcinogenesis attenuating potential of ethanolic extract of M. indicus (L.) All. (Miet) in a 7,12-dimethylbenz[a]anthracene (DMBA)-induced skin cancer model. The ethanolic extract of the plant was prepared by a maceration method. HPLC analysis indicated the presence of quercetin in abundance and also various other phytoconstituents. DPPH radical scavenging assay results showed moderate antioxidant potential (IC50 = 93.55 ± 5.59 μg/mL). A topical acute skin irritation study showed the nonirritant nature of Miet. Data for the skin carcinogenic model showed marked improvement in skin architecture in Miet and its primary phytochemicals (quercetin and coumarin) treated groups. Miet 50% showed comparable effects with 5-fluorouracil. Significant (p < 0.05) anticancerous effects were seen in coumarin-quercetin combination-treated animals than in single agent (coumarin and quercetin alone)-treated animals. Chorioallantoic membrane (CAM) assay results showed the antiangiogenic potential of Miet. Treatment with Miet significantly down-regulated the serum levels of CEA (carcinoembryonic antigen) and TNF-α (Tumor necrosis factor-α). Data for the docking study indicated the binding potential of quercetin and coumarin with TNF-α, EGFR, VEGF, and BCL2 proteins. Thus, it is concluded that Miet has skin cancer attenuating potential that is proposed to be due to the synergistic actions of its bioactive molecules. Further studies to explore the effects of Miet and its bioactive molecules as an adjuvant therapy with low dose anticancer drugs are warranted, which may lead to a new area of research.

Abstract
Uncontrolled inflammation plays a central role in the pathogenesis of various diseases. Currently available anti-inflammatory agents on prolonged use may lead to ulcers or thrombus formation. The present study was designed to evaluate the anti-inflammatory, anti-arthritic and anti-angiogenic potentials of methanol extract of Viola betonicifolia using battery of in vivo models. Methanol extract of Viola betonicifolia (Vb.Me) was prepared through maceration. High performance liquid chromatography (HPLC) and gas chromatography mass spectrometery (GC-MS) were performed to identify bioactive compounds present in Vb.Me. In vivo safety profile of Vb.Me was evaluated following OECD 425 acute toxicity guidelines. Anti-inflammatory potential of Vb.Me at three different dose levels was evaluated in in vivo acute (carrageenan and, histamine-induced paw oedema), sub-chronic (cotton pellet-induced granuloma) and chronic (Complete Freund's adjuvant-induced arthritis) models. Blood and paws samples were collected to study effects of Vb.Me treatment on the expression of various pro- and anti-inflammatory genes (RT-PCR) and to study the histopathological changes at tissue levels. Effects of Vb.Me on neovasculature development were studied in ex-ovo chicken chorioallantoic membrane (CAM) assay. Quercetin and n-hexadecanoic were identified as one of the major bioactive molecules in HPLC and GC-MS analysis of Vb.Me. Toxicity data revealed that Vb.Me was safe for administration up to the dose of 2000 mg/kg. Findings of inflammatory models showed that Vb.Me produced time and dose-dependent effects. 500 mg/kg Vb.Me showed significantly (p < 0.05) better effects as compared with 125 and 250 mg/kg. 500 mg/kg Vb.Me also showed comparable anti-inflammatory effects with indomethacin in both acute and chronic models respectively. RT-PCR data exhibited significant (p < 0.05) down-regulation of IL-6, IL-1ß, NF-kß, TNF-α and COX-2 genes with simultaneous up-regulation of IL-4 and IL-10 genes in the blood samples of animals treated with 500 mg/kg of Vb.Me and 10 mg/kg of indomethacin respectively. CAM assay data revealed arrest of microvessel outgrowth in Vb.Me-treated eggs. Altogether, findings of the current study indicate that Vb.Me exerts in vivo anti-inflammatory and anti-angiogenic effects through regulation of expression of various pro- and anti-inflammatory genes. Synergist actions of various bioactive molecules in Vb.Me are proposed to be responsible for these attributes. However, further studies to standardize the extract and evaluation of its potential in various inflammation-induced diseases are warranted.

Ziziphus Oxyphylla hydro-methanolic extract ameliorates hypertension in L-NAME induced hypertensive rats through NO/cGMP pathway and suppression of oxidative stress related inflammatory biomarkers. JOURNAL OF ETHNOPHARMACOLOGY 2022; 285:114825. [PMID: 34774683 DOI: 10.1016/j.jep.2021.114825] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 09/20/2021] [Accepted: 11/05/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ziziphus Oxyphylla belongs to family Ziziphus and has been used traditionally in hypertension. It is enriched with quercetin and kaempferol derivatives, catechin and cyclopeptide alkaloids. AIM The current research evaluates the antihypertensive potential of aqueous methanolic extract of Z. oxyphylla (AMEZO) in NG-nitro-L-arginine methyl ester (LNAME) induced hypertension in rats. MATERIAL AND METHODOLOGY Phytochemical analysis of AMEZO was carried out using high performance liquid chromatography (HPLC) and electrospray ionization mass spectrometry (ESI-MS/MS). Antihypertensive activities of AMEZO (200 and 400 mg/kg) and Kaempferol were assessed in L-NAME (185 μmol/kg, intraperitoneal) injected hypertensive rats. In normotensive rats, blood pressure was assessed using Power Lab data system. Serum and tissue samples were preserved for estimation of nitric oxide (NO), Cyclic guanosine monophosphate (cGMP), interleukin-6 (IL-6), tumor necrosis factor (TNF- α) and oxidative stress markers respectively. mRNA levels of eNOS, ACE, COX-2 and NF-kB genes were assessed through qPCR. RESULTS The HPLC and ESI-MS/MS identified kaempferol, quercetin, catechin, ceanothic acid, zizybernalic acid and oxyphylline F. Chronic administration of AMEZO and kaempferol in L-NAME induced hypertensive rats significantly (p < 0.001) reduced systolic, diastolic and mean blood pressure. AMEZO and kaempferol caused meaningfully improved (p < 0.001) serum NO and cGMP levels. AMEZO administration also noticeably decrease the elevated IL-6 and TNF- α concentration in hypertensive animals. Administration of AMEZO and kaempferol also improved oxidative stress markers (MDA, CAT, SOD, GSH). The antihypertensive activity of AMEZO also resulted in upregulation of eNOS and downregulation of ACE. CONCLUSION These data depict that AMEZO and kaempferol showed antihypertensive activity in LNAME induced hypertensive rats possibly mediated through improvement in NO and cGMP levels, modulation of mRNA expression of eNOS, ACE, COX-2 and NF-kB and suppression of oxidative stress related inflammatory markers, proposing a defensive role in cardiovascular diseases.

Abstract
BACKGROUND Raphanus sativus is traditionally used as an anti-inflammatory agent. OBJECTIVES The current study was designed to explore the in vivo anti-inflammatory and antiangiogenic properties of Raphanus sativus seeds oil. METHODS Cold press method was used for the extraction of oil (RsSO) and was characterised using GC-MS techniques. Three in vitro antioxidant assays (DPPH, ABTS, and FRAP) were performed to explore antioxidant potential of RsSO. Disc diffusion methods were used to study in vitro antimicrobial properties. In vivo anti-inflammatory properties were studied in both acute and chronic inflammation models. In ovo chicken, a chorioallantoic membrane assay was performed to study antiangiogenic effects. Molecular mechanisms were identified using serum TNF-α ELISA kit and docking tools. RESULTS GC-MS analysis of RsSO revealed the presence of hexadecanoic and octadecanoic acid. Findings of DPPH, ABTS, and FRAP models indicated relatively moderate radical scavenging properties of RsSO. Oil showed antimicrobial activity against a variety of strains tested. Data of inflammation models showed significant (p < 0.05) anti-inflammatory effects of RsSO in both acute and chronic models. 500 mg/kg RsSO halted inflammation development significantly better (p < 0.05) as compared with lower doses. Histopathological evaluations of paws showed minimal infiltration of inflammatory cells in RsSO-treated animals. Findings of TNF-α ELSIA and docking studies showed that RsSO has the potential to downregulate the expression of TNF-α, iNOS, ROS, and NF-κB, respectively. Moreover, RsSO showed in vivo antiangiogenic effects. CONCLUSION Data of the current study highlight that Raphanus sativus seeds oil has anti-inflammatory, and antiangiogenic properties and can be used as an adjunct to standard NSAIDs therapy to reduce its dose and side effects.

Abstract
INTRODUCTION Inflammation is a vital reaction of the natural immune system that protects against encroaching agents. However, uncontrolled inflammation can lead to complications. Trigonella foenumgraecum is traditionally used as an anti-inflammatory herb. OBJECTIVES The current study was conducted to explore the antioxidant, anti-inflammatory, and antiangiogenic potentials of Trigonella foenum-graecum seeds oil. METHODS Oil was extracted from seeds of Trigonella foenum-graecum by cold press method and labelled as TgSO. Phytochemical (GC-MS, Folin-Ciocalteu method) and metal analyses were conducted to evaluate the metalo-chemical profile of TgSO. In vitro antioxidant assays (2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis-3- ethylbenzothiazoline-6-sulfonic acid and ferric reducing antioxidant power) were performed to assess its antioxidant potential. In vitro antimicrobial activity was evaluated using agar disc diffusion method and the safety profile of TgSO was assessed in acute toxicological studies following OECD 425 guidelines. In vivo antiinflammatory activities of TgSO were assessed in carrageenan, serotonin, histamine, formalin, and cotton pelletinduced oedema models. Serum TNF-α, Superoxide Dismutase (SOD) and, Catalases (CAT) levels were assessed by ELISA kits. In vivo antiangiogenic activity of TgSO was screened in chick Chorioallantoic Membrane (CAM) assay. Histopathological studies using excised paws were conducted to observe the effects of TgSO treatment at the tissue level. In silico docking studies were conducted to screen the binding potentials of identified compounds with TNF-α. RESULTS Extraction by cold press method yielded 16% of TgSO. Phytochemical analysis of TgSO through GCMS showed the presence of eugenol, dihydrocoumairn, heptadecanoic acid, tri- and tetradecanoic acid, and hexadecanoic acid, respectively. Total phenolic contents of TgSO were found to be 0.30±0.01mg/g gallic acid equivalent in Folin-Ciocalteu method. Metal analysis indicated the presence of different metals in TgSO. Findings of antioxidant models showed the moderate antioxidant potential of TgSO. Findings of antimicrobial assays showed that TgSO was active against bacterial (S. aureus, S. epidermidis) and fungal (C. albicans, and A. niger) strains. In vivo toxicity study data showed that TgSO was safe up to the dose of 5000 mg/kg. Data of oedema models showed a significant (p<0.05) reduction in oedema development in TgSO treated animals in both acute and chronic models. Histopathological evaluations of paws showed minimum tissue infiltration with inflammatory cells in TgSO-treated animals. Treatment with TgSO also significantly (p<0.05) down-regulated TNF-α in serum while levels of SOD and CAT were up-regulated. Findings of the CAM assay revealed the antiangiogenic activity of TgSO. Findings of in silico docking studies showed that identified phytoconstituents can bind with culprit cytokine (TNF-α). CONCLUSION Data obtained from the current study conclude that TgSO has antioxidant, anti-inflammatory, and antiangiogenic effects that validate its traditional uses. Synergistic actions of different phytoconstituents are proposed to be responsible for the observed effects.

Abstract
Purpose Rheumatoid arthritis is an autoimmune disorder that directly affects joints. However, other body organs including heart, eyes, skin, blood vessels and lungs may also be affected. The purpose of this study was to design and evaluate a nanoemulgel formulation of diflunisal (DIF) and solubility enhanced diflunisal (DIF-IC) for enhanced topical anti-inflammatory activity. Methodology Nanoemulsion formulations of both DIF and DIF-IC were prepared and incorporated in three different gelling agents, namely carboxymethylcellulose sodium (CMC-Na), sodium alginate (Na-ALG) and xanthan gum (XG). All the formulations were evaluated in term of particle size, pH, conductivity, viscosity, zeta potential and in vitro drug release. The formulation 2 (NE2) of both DIF and DIF-IC which expressed optimum release and satisfactory physicochemical properties was incorporated with gelling agents to produce final nanoemulgel formulations. The optimized nanoemulgel formulation was subjected to three different in vivo anti-inflammatory models including carrageenan-induced paw edema model, histamine-induced paw edema model and formalin-induced paw edema model. Results DIF-IC-loaded nanoemulgel formulations yielded significantly enhanced in vitro skin permeation than DIF-loaded nanoemulgel. The nanoemulgel formulation of DIF-IC formulated with XG produced improved in vivo anti-inflammatory activity. Conclusion It was recommended that DIF-IC-based nanoemulgel formulation prepared with XG could be a better option for effective topical treatment of inflammatory conditions.

Chemical Profile of Launaea nudicaulis Ethanolic Extract and Its Antidiabetic Effect in Streptozotocin-Induced Rats. Molecules 2021; 26:1000. [PMID: 33668635 PMCID: PMC7918448 DOI: 10.3390/molecules26041000] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 02/07/2021] [Accepted: 02/07/2021] [Indexed: 11/24/2022] Open
Abstract
Launaea nudicaulis is used in folk medicine worldwide to treat several diseases. The present study aimed to assess the antidiabetic activity of L. nudicaulis ethanolic extract and its effect on diabetic complications in streptozotocin-induced hyperglycemic rats. The extract was orally administrated at 250 and 500 mg/kg/day for 5-weeks and compared to glibenclamide as a reference drug at a dose of 5 mg/kg/day. Administration of the extract exhibited a potential hypoglycemic effect manifested by a significant depletion of serum blood glucose concurrent with a significant elevation in serum insulin secretion. After 5-weeks, extract at 250 and 500 mg/kg/day decreased blood glucose levels by about 53.8 and 68.1%, respectively, compared to the initial values (p ≤ 0.05). The extract at the two dosages prevented weight loss of rats from the 2nd week till the end of the experiment, compared to diabetic control rats. The extract further exhibited marked improvement in diabetic complications including liver, kidney and testis performance, oxidative stress, and relative weight of vital organs, with respect to diabetic control. Histopathological examinations confirmed the previous biochemical analysis, where the extract showed a protective effect on the pancreas, liver, kidney, and testis that degenerated in diabetic control rats. To characterize extract composition, UPLC-ESI-qTOF-MS identified 85 chromatographic peaks belonging to flavonoids, phenolics, acyl glycerols, nitrogenous compounds, and fatty acids, with four novel phenolics reported. The potential anti-diabetic effect warrants its inclusion in further studies and or isolation of the main bioactive agent(s).

Abstract
Asphodelus tenuifolius is traditionally used in the management of rheumatic pain and inflamed body parts. The current study validated its traditional use as an anti-arthritic and anti-inflammatory agent using a series of in vivo models. Carrageenan and histamine-induced acute oedema models were employed to study the effects of n-hexane (n-HeAT) and ethanolic (EeAT) extracts on acute inflammatory mediators and were found to inhibit oedema formation in a dose-dependent manner. Formalin and complete Freund's adjuvant (CFA) were injected into the hind paw of rats for the induction of arthritis. In the formalin model both n-HeAT and EeAT showed significantly better (p < 0.05) anti-oedema effects from day 6 onward. In CFA model rats were treated on 8th day of induction with extracts at the doses of 250, 500, and 750 mg/kg respectively. Piroxicam (10 mg/kg) and normal saline (10 mL/kg) were used as positive and negative controls respectively. Both n-HeAT and EeAT significantly (p < 0.05) decreased arthritis development in a time-dependent manner and at 28th day extent of inflammation was even less than that observed at day 8. The arthritic score was measured at day 12, 16, 20, 24, and 28 and was observed to be significantly less (p < 0.05) in animals treated with 750 mg/kg of n-HeAT and EeAT, respectively. Joint inflammation (p < 0.01), bone erosion (p < 0.001) and, pannus formation (p < 0.01) were significantly declined in A. tenuifolius treatment groups. Radiographic evaluations (X-ray) were conducted to check bone integrity and extent of inflammation and were observed to be diminished at day 28 in A. tenuifolius extracts treated groups. HPLC was performed to screen the phytochemical profile of n-HeAT and EeAT and were found to contain flavonoids and phenolic compounds. Quantitative real-time polymerase chain reaction (qPCR) was performed to detect effects of n-HeAT and EeAT treatments on inflammatory markers i.e., IL-4, IL-6, IL-10, COX-2, NF-κB, and I-κB using blood samples. ELISA assays were performed for the detection of levels of C-reactive proteins, respectively. Significant downregulation of TNF-α, IL-4, IL-6, IL-1β, COX-2, NF-κB with simultaneous upregulation of IL-10 and I-κB was observed in n-HeAT and EeAT treatment groups. ELISA assays also showed significant (p < 0.05) down-modulation in the serum levels of CRP and TNF-α. Both extracts showed relatively weak antioxidant activities as compared with ascorbic acid in in vitro assay. Based on findings of the current study it is concluded that A. tenuifolius has anti-inflammatory and anti-arthritic effects and thus has potential to be used as an adjunct to standard NSAIDs therapy.Graphic abstract.

Abstract
Chronic wounds may lead to the development of various pathological conditions such as diabetic foot ulcers and pressure sores. The current study evaluated wound healing and anti-inflammatory potentials of methanolic extract of Ephedra ciliata using series of in vivo models. Methanolic extract of Ephedra ciliata was prepared by maceration (Ec.Me). Qualitative and quantitative (HPLC) phytochemical and metal analyses were conducted to explore the chemical and metal profiles of Ec.Me. Safety profile (behavioural) and, antimicrobial, antioxidant, wound healing, anti-inflammatory and anti-angiogenic potentials of Ec.Me were evaluated using well-established in vitro and in vivo models. ELISA assay was performed to estimate the effects of Ec.Me treatment on serum levels of TNF-α. HPLC analysis identified quercetin as one of the major compounds in Ec.Me. Safety study data showed that Ec.Me was safe up to the dose of 2000 mg/kg. Antimicrobial assay data showed that Ec.Me was active against bacterial (Staphylococcus aureus) as well as fungal (Candida albicans and Aspergillus niger) strains. Ec.Me showed modertate antioxidant potential in in vitro and in vivo models. Data of excision and burn wound healing models showed that Ec.Me, promoted wound closure in a dose and time-dependent manner. Treatment with 20% Ec.Me cream and heparin showed almost the same effects with no statistical differences (p > 0.05). Ec.Me also showed time-dependent anti-inflammatory activities in both acute and chronic models. In carrageenan model, treatment with 200 mg/kg of Ec.Me showed comparable anti-inflammatory effects (p > 0.05) with quercetin and indomethacin throughout the study. In cotton pellet granuloma model treatment with 200 mg/kg of Ec.Me and indomethacin inhibited granuloma formation significantly better (p < 0.05) as compared with the rest of the treatment groups. Histopathological examination of skin samples showed marked improvement in architecture with minimal infiltration of inflammatory cells. Data of in vivo angiogenesis assay showed marked improvement in vessels length, density, branching points, total segments and total nets after treatment with Ec.Me, indicating no toxic effects towards vasculature development. Significant (p < 0.05) downregulation of TNF-α was observed in serum samples of animals treated with Ec.Me. Based on data of the current study, it is concluded that quercetin-rich extract of Ephedra ciliata has wound healing and anti-inflammatory potentials via downregulation of TNF-α. Moreover, it is suggested that the antimicrobial activity of Ec.Me prevented microbial invasion, thus promoted natural wound healing mechanisms as well.

Abstract
Inflammation and angiogenesis are two major contributors to tumourigenesis. Melilotus indicus is traditionally used as an anti-inflammatory agent. The current study was designed to investigate the anti-inflammatory and anti-angiogenic properties of ethanolic extract of M. indicus (Miet) whole plant and its marker compound (coumarin) using a series of in vivo methods. Extraction by maceration was adopted to prepare ethanolic extract. Phytochemical compounds present in Miet were investigated using both qualitative and quantitative methods. In vivo safety profile of Miet was investigated in behavioural studies. Four acute oedema models such as carrageenan, serotonin, histamine-induced paw oedema and xylene-induced ear oedema, and chronic formaldehyde-induced paw oedema model were employed to explore the anti-inflammatory potential of Miet. Chorioallantoic chick membrane assay (CAM) was performed to explore anti-angiogenic potential of Miet. Histopathological evaluations were conducted to access improvement in skin texture of paws. TNF-α ELISA kit was used to study effects of treatment on serum levels of TNF-α. Extraction by maceration resulted in formation of greenish coloured semisolid extract with a high coumarin content. In vivo toxicological studies revealed LD50 of Miet was greater than 8000 mg/kg. Data of acute inflammatory models depicted significant (p < 0.05) inhibition of oedema in Miet, coumarin and standard (piroxicam/indomethacin) treated groups. 750 mg/kg of Miet induced comparable (p > 0.05) anti-inflammatory effects to that of standard-treated groups. Coumarin showed better anti-inflammatory effects in carrageenan-induced paw oedema model as compared with histamine- and serotonin-induced oedema models. Data of chronic inflammatory models also depicted dose-dependent anti-inflammatory attributes of Miet which were comparable with standard treated groups. Significant (p > 0.05) downregulation of TNF-α in serum samples of animals treated with Miet and piroxicam was observed as compared with control group. Furthermore, Miet significantly halted blood vessels formation in CAM assay. Overall, data of the current study highlight that M. indicus has anti-inflammatory and anti-angiogenic potentials, and, thus, can potentially be used as an adjuvant therapy in solid tumours management.
