JOURNAL OF ETHNOPHARMACOLOGY 2023; 310:116417. [PMID: 36990302 DOI: 10.1016/j.jep.2023.116417] [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: 12/28/2022] [Revised: 03/17/2023] [Accepted: 03/20/2023] [Indexed: 06/19/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Campomanesia lineatifolia Ruiz & Pavón (Myrtaceae), an edible species found in Brazilian Forest, possesses leaves that are traditionally used for the treatment of gastrointestinal disorders in Brazil. Extracts of C. lineatifolia are rich in phenolics and exhibit antioxidant, and gastric antiulcer properties. Furthermore, Campomanesia spp. have been described to possess anti-inflammatory properties, but studies related to chemical constituents of C. lineatifolia are scarce in the literature. AIM OF THE STUDY This work aims to identify the chemical composition of the phenolic-rich ethanol extract (PEE) from C. lineatifolia leaves and evaluate the anti-inflammatory activity that could be related to its ethnopharmacological use. MATERIALS AND METHODS The high-speed countercurrent chromatography (HSCCC), using an isocratic and a step gradient elution method, and NMR, HPLC-ESI-QTOF-MS/MS were used to isolate and identify the chemicals of PEE, respectively. Lipopolysaccharide-(LPS)-stimulated THP-1 cells were used to evaluate the anti-inflammatory activities from PEE and the two majority flavonoids isolated by measure TNF-α and NF-κB inhibition assays. RESULTS Fourteen compounds were isolated from the PEE, further identified by NMR and HPLC-ESI-QTOF-MS/MS, twelve of them are new compounds, and two others are already known for the species. The PEE, quercitrin and myricitrin promoted a concentration-dependent inhibition of TNF-α, and PEE promoted an inhibition of NF-κB pathway. CONCLUSIONS PEE from C. lineatifolia leaves demonstrated significant anti-inflammatory activity that may be related to the traditional use to treat gastrointestinal disorders.

Anti-inflammatory effect of leaves of Vernonia zeylanica in lipopolysaccharide-stimulated RAW 264.7 macrophages and carrageenan-induced rat paw-edema model. JOURNAL OF ETHNOPHARMACOLOGY 2021; 274:114030. [PMID: 33741441 DOI: 10.1016/j.jep.2021.114030] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 03/07/2021] [Accepted: 03/12/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Vernonia zeylanica (L.) Less (Family: Compositae) is a medicinal plant used as external applications for boils, bone fractures, eczema and internally for asthma in traditional medicine in Sri Lanka. Anti-nociceptive, anti-bacterial and anti-proliferative activities have been reported previously. AIM OF THE STUDY To investigate the anti-inflammatory activity of methanol/dichloromethane extract (MDE) of leaves of V. zeylanica by assessing in vivo inhibition of rat paw-edema, in vitro inhibition of the production of nitric oxide (NO) and superoxide and inhibitory effect on inducible nitric oxide synthase (iNOS) gene expression. MATERIALS AND METHODS In vivo anti-inflammatory activity of MDE was tested at the dose of 1500 mg/kg using rat paw-edema model. Indomethacin and Gum acacia was used as the positive and vehicle control respectively. In vitro NO inhibitory activity of 7.8-250 μg/ml MDE was tested using lipopolysaccharide (LPS)-stimulated (1 μg/ml) mouse macrophages (RAW264.7 cells) and rat peritoneal cells (RPC) obtained following carrageenan-induction (5 mg/Kg). Griess method was used to quantify the nitrite levels in culture supernatants. In vitro inhibition of superoxide production of Phorbal 12-myristate 13-acetate (PMA)-stimulated RAW cells was determined by quantitative Nitroblue Tetrazolium (NBT) assay. N-monomethyl-L-arginine acetate (NMMA) (1 mM) and Diphenyleneiodonium chloride (DPI) (10 μM) were used as the positive controls for inhibitory activity of NO and superoxide production respectively. Reverse transcriptase polymerase chain reaction (RT-PCR) analysis was carried out to test the inhibitory effect on mRNA expression of iNOS gene. RESULTS Treatment with MDE of V. zeylanica at 1500 mg/kg showed significant inhibition of paw-edema from 1st-5th hour (P < 0.01) compared with the control. The reference drug, indomethacin showed a biphasic pattern and its highest inhibition was (98.3 ± 7.1%) at 4th h (P < 0.01). MDE of V. zeylanica showed similar inhibition of paw-edema with highest inhibition recorded as 94.5 ± 5.28%, at 5th h (P < 0.01). The inhibitory concentration (IC50) of MDE for in vitro NO inhibitory activity was 105 μg/ml for RAW cells and 80 μg/ml for RPCs. Both NO inhibitory activities showed significant dose-dependency (r = 0.998 and r = 0.915 respectively; p < 0.05). MDE concentration of 250 μg/ml showed 55% inhibition of ROS production in RAW cells. NMMA showed 78% and 70.1% inhibition of NO production with RAW cells and RPCs whereas DPI showed 61% superoxide inhibitory activity with RAW cells. NO inhibitory activity of MDE on RAW cells was confirmed by the significant reduction (99.1%) in iNOS gene expression. CONCLUSION These results demonstrated potent anti-inflammatory activity of MDE of V. zeylanica reflected by its significant in vivo inhibition of rat paw-edema, in vitro inhibition of NO and superoxide production, and the reduction of iNOS gene expression. Thus, further purification and isolation of bioactive compounds from V. zeylanica are emphasized.

Catelan TBS, Santos Radai JA, Leitão MM, Branquinho LS, Vasconcelos PCDP, Heredia-Vieira SC, Kassuya CAL, Cardoso CAL. Evaluation of the toxicity and anti-inflammatory activities of the infusion of leaves of Campomanesia guazumifolia (Cambess.) O. Berg. JOURNAL OF ETHNOPHARMACOLOGY 2018; 226:132-142. [PMID: 30114515 DOI: 10.1016/j.jep.2018.08.015] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2018] [Revised: 06/26/2018] [Accepted: 08/12/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Some species of Campomanesia are used in the folk medicine due to anti-inflammatory, anti-diarrheal, anti-diabetes and hypercholesterolemic. However studies with Campomanesia guazumifolia (Cambess.) O. Berg. are scarce. AIM OF THE STUDY This study investigated the anti-inflammatory activity and toxicological profile of infusion obtained from leaves of Campomanesia guazumifolia in mice. MATERIALS AND METHODS Leaves infusion of C. guazumifolia was obtained in the proportion of 20 g/L (leaves/water) at 95-100 °C for 10 min in an enclosed container. The acute toxicity of the leaves infusion of C. guazumifolia lyophilized (ICG) was assessed by oral administration to female mice at doses of 500, 1000, 2000, and 5000 mg/kg, and the general behavior and toxic symptoms were observed for 14 days. In the subacute toxicity model, female mice were treated orally with the ICG (250, 500, and 1000 mg/kg) during 28 days, and biochemical, toxic signs and the estrous cycle were evaluated. The anti-inflammatory activity of the ICG (70, 300 and 700 mg/kg) was analyzed using carrageenan-induced pleurisy and inflammatory paw (mechanical and thermal hyperalgesia). RESULTS Three flavonoids glycosylated and a cyclohexanecarboxylic acid were identified in the ICG: quercetin pentose, quercetin deoxyhexoside, myricetin deoxyhexoside and quinic acid. No clinical signs of acute toxicity were observed, suggesting that the LD50 (Lethal Dose) is above 5000 mg/kg. Subacute exposure of mice to the ICG did not change significantly the hematological and biochemical parameters as well as histology of organs. The ICG increased the duration of estrous cycle in all phases, showing anti-inflammatory potential by decreasing leukocyte migration, extravasation protein in the pleural cavity and antiedematogenic activity. The ICG treatment at a dose of 700 mg/kg decreased the mechanical hyperalgesia, while at doses of 300 mg/kg and 700 mg/kg, decreased the sensitivity to the cold. CONCLUSION The results evidenced the anti-inflammatory potential with low toxicity of infusion of the leaves of C. guazumifolia, supporting the popular use of this species.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Campomanesia velutina leaves and branches infusions are used in Brazilian folk medicine to treat diarrhea and to ameliorate intestinal cramps, respectively. AIM OF THE STUDY Carry out the acute and sub chronic pre-clinical evaluation and thus assess the safety and toxicological potential of the specie. MATERIALS AND METHODS In vivo toxicity was evaluated by acute and sub chronic toxicity assays conducted according to the guidelines of the Brazilian Agency of National Health Surveillance (Agência Nacional de Vigilância Sanitária - ANVISA). For acute toxicity evaluation, a single dose of aqueous extracts from the leaves (AEL) and branches (AEB) of Campomanesia velutina were orally administered to mice at doses of 300, 600 and 1200mg/kg. Then, the animals were observed for 14 days. In the sub chronic study, the extracts were orally administered to mice for 14 days at doses of 300, 600 and 1200mg/kg. To assess the toxicological effects, animals were closely observed on general behavior, clinical signs of toxicity, body weight, food and water intake. At the end of the experiment, it was performed biochemical and hematological evaluations, as well as histopathological analysis from the following organs: brain, heart, lungs, liver, stomach, small intestine (section) and left kidney. Preliminary phytochemical analysis was performed using thin layer chromatography (TLC) and colorimetric pharmacognostic tests. RESULTS In oral acute assay, treatment with AEB at the major dose (1200mg/kg) caused diarrhea, abdominal cramps and tremors in females. These effects were reversed at 4th hour. Normochromic normocytic anemia was observed in males treated with AEL 300mg/kg and AEB 600 and 1200mg/kg as well as in females treated with AEB 300 and 1200mg/kg. The kidney of all treated animals showed moderate inflammation and a few hemorrhagic points. In sub chronic assay, treatment with AEL 600mg/kg, AEL 1200mg/kg and AEB 1200mg/kg caused hyper excitability in females that was not reversed. Treatments also had impact on weight gain and the relative weight of males' brain was increased on group treated with AEL 300mg/kg, AEB 300 and AEB 1200mg/kg. Although changes in hematological parameters were not observed, serum creatinine levels were significantly higher in males treated with AEB 300mg/kg. Besides, the heart of all treated animals showed intense hyperemia. Preliminary phytochemical analysis revealed the presence of flavonoids, tannins and phenolic compounds. CONCLUSIONS Toxicity signs were mainly observed after treatment with AEL and AEB at the two highest tested doses (600 and 1200mg/kg), suggesting that the extracts are relatively safe at its effective dose (300mg/kg). However, alterations on hematological and biochemical parameters and on the kidney and heart of the animals were not closely related with the dose, implying caution on its use.

Abstract
Campomanesia xanthocarpa (Myrtaceae) is used in Brazilian traditional medicine against fever, diabetes, hypercholesteremic, obesity, and urinary diseases. In the present study, the compounds 2',6'-dihydroxy-3'-methyl-4'-metoxychalcone and 2',4'-dihydroxy-3',5'-dimethyl-6'-methoxychalcone were identified for the first time in leaves of the C. xanthocarpa. These compounds and the hydroethanolic extract (HECX) significantly inhibited paw edema and reduced both leukocyte migration and the leakage of protein into the pleural cavity. No toxicity was detected by HECX in an acute toxicity test.

Abstract
OBJECTIVE The objective of this study is to investigate the fate of albumin coupled nanoparticulate system over non-targeted drug carrier in the treatment of hemisectioned spinal cord injury (SCI). SIGNIFICANCE Targeted delivery of methyl prednisolone (MP) and minocycline (MC) portrayed improved therapeutic efficacy as compared with non-targeted nanoparticles (NPS). METHODS Albumin coupled, chitosan stabilized, and cationic NPS (albumin-MP + MC - NPS) of poly-(lactide-co-glycolic acid) were prepared using the emulsion solvent evaporation method. Prepared NPS were characterized for drug entrapment efficiency, particle size, poly-dispersity index (PDI), zeta potential, and morphological characteristics. Their evaluation was done based on the pharmaceutical, toxicological, and pharmacological parameters. RESULTS AND DISCUSSION In vitro release of MP + MC from albumin-MP + MC - NPS and MP + MC - NPS was observed to be very controlled for the period of eight days. Cell viability study portrayed non-toxic nature of the developed NPS. Albumin-MP + MC - NPS showed prominent anti-inflammatory potential as compared with non-targeted NPS (MP + MC - NPS) when studied in LPS-induced inflamed astrocytes. Albumin-MP + MC - NPS reduced lesional volume and improved behavioral outcomes significantly in rats with SCI (hemisectioned injury model) when compared with that of MP + MC - NPS. CONCLUSIONS Albumin-coupled NPS carrier offered an effective method of SCI treatment following safe co-administration of MP and MC. The in vitro and in vivo effectiveness of MP + MC was improved tremendously when compared with the effectiveness showed by MP + MC - NPS. That could be attributed to the site specific, controlled release of MP + MC to the inflammatory site.

Abstract
Health benefits of hop polyphenols are well studied. In the present investigation, we examined the antioxidant activity, anti-nitric oxide (NO) production, and anti-adipocyte differentiation of polyphenols extracted from hops (HPP), harvested at different times for over 4years. Saaz hop variety from the Czech Republic was used in the in vitro assays. Twenty-three polyphenols were quantitatively analyzed using Orbitrap liquid chromatography-mass spectrometry (LC-MS), and their health promoting effects were assayed individually. Strong effects of low concentrations of HPP were observed in the above three assays. A significant increase in anti-adipocyte differentiation activity per unit weight of HPP was obtained in the early harvested samples. A significant difference in anti-NO production activity per unit weight of HPP was observed among the different harvest years. HPP significantly increased in early harvested samples. Our results suggest that some in vitro functional properties of hops vary with harvest time and year and are dependent on different polyphenols.

Abstract
Stryphnodendron species, popularly named "barbatimão," are traditionally used in Brazil as anti-inflammatory agents. This study aimed to investigate the effect of barbatimão and 11 other species on the production of tumor necrosis factor-alpha (TNF-α) in lipopolysaccharide- (LPS-) stimulated THP-1 cells, as well as their anti-arthritis activity. The extracts of Stryphnodendron adstringens, Stryphnodendron obovatum, Campomanesia lineatifolia, and Terminalia glabrescens promoted a concentration-dependent inhibition of TNF-α. Mice injected with LPS in the knee joint were treated per os with fractions from the selected extracts. Both the organic (SAO) and the aqueous (SAA) fractions of S. adstringens promoted a dose-dependent reduction of leukocyte migration and neutrophil accumulation into the joint, but none of them reduced CXCL1 concentration in the periarticular tissue. In contrast, treatment with C. lineatifolia and T. glabrescens fractions did not ameliorate the inflammatory parameters. Analyses of SAO by Ultra Performance Liquid Chromatography (UPLC) coupled to electrospray ionization mass spectrometry (ESI-MS) led to the identification of gallic acid along with 11 prodelphinidins, characterized as monomers and dimers of the B-type. Our findings contribute to some extent to corroborating the traditional use of S. adstringens as an anti-inflammatory agent. This activity is probably related to a decrease of leukocyte migration into the inflammatory site. Polyphenols like gallic acid and prodelphinidins, identified in the active fraction, may contribute to the observed activity.

Campomanesia adamantium (Myrtaceae) is a medicinal plant distributed in Brazilian Cerrado. Different parts of this plant are used in popular medicine for treatment of several diseases like fever, diarrhea, hypercholesterolemia and rheumatism. The aim of this work was to evaluate the inhibition of heat-stable enterotoxin type A (STa) by gallic acid present in the peel of C. adamantium fruit and assays to assess the antidiarrheal activity, anti-inflammatory and cytotoxic properties of peel extract using the T84 cell line model. The possible inhibition exerted by the gallic acid of the peel extract on the STa peptide was inferred by molecular dynamics simulations. The antidiarrheal effects were investigated measuring cGMP accumulation in cells after stimulation by STa toxin and antibacterial activity was assessed. The anti-inflammatory activity was assessed by inhibition of COX-1 and COX-2. MTT and LDH assays were used to evaluate any possible cytotoxic action while the CyQUANT test was used to investigate the effect on cell proliferation. A representation showing how the possible interactions between STa and the gallic acid of the extract might reduce the action of the enterotoxin is presented. C. adamantium peel extract significantly decreased the levels of cGMP in T84 cells. However, no effect on the species of microorganisms was observed. The extract also inhibited COX-1 (IC50 255.70 ± 0.04 ng/mL) and COX-2 (IC50 569.50 ± 0.11 ng/mL) enzymes. Cytotoxicity assay have shown significant changes in cells treated with the extract, which inhibited the cell proliferation until 72 hours of treatment. Direct interactions of phenolic compounds present in the extract with the STa toxin may limit its activity. Curative effect in the diarrhea treatment and its anti-inflammatory action is based on the pharmacological properties, mechanism of action of the C. adamantium peel extract, and no toxic effects of the peel extract presented on this work.
