Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE Brazilian medicinal species of the Psidium genus are rich in secondary metabolites such as terpenes and phenolic compounds and present biological activities for several human diseases. For the native Psidium species, there are no specific research reports for any member of the genus about ethnobotanical research, hindering the joint analysis of its therapeutic indications together with the scientific evidence already investigated. STUDY OBJECTIVE Analyze the therapeutic indications, the main chemical constituents, and the biological activities of native species of the Psidium to Brazil. MATERIALS AND METHODS Systematic research was carried out in the Scopus, ScienceDirect, PubMed, and Web of Science databases over a period of ten years. Articles in English, Portuguese and Spanish were used. The research was divided into three phases, seeking information on ethnobotany, chemical composition and biological activities. The words were combined to structure the descriptors used in the search. RESULTS A total of 13 native species belonging to the Psidium genus were identified in this analysis, Psidium acutangulum DC., Psidium brownianum Mart. ex DC., Psidium cattleyanum Sabine, Psidium densicomum Mart. ex DC., Psidium grandifolium Mart. ex DC., Psidium guineense Sw., Psidium laruotteanum Cambess., Psidium myrsinites DC, Psidium myrtoides O. Berg, Psidium salutare (Kunth) O. Berg, Psidium schenckianum Kiaersk., Psidium sobralianum Proença & Landrum, Psidium striatulum Mart. ex DC. Of these, six were indicated in folk medicine, digestive system disorders being their main therapeutic indication. Most species presented an investigation of chemical composition and biological activity. They are rich in phenolic compounds, flavonoids, and terpenes and have antimicrobial, antioxidant, antiproliferative, and repellent activities. CONCLUSIONS Native species of the Psidium genus are important sources of active ingredients in combating adversities that affect the human health, especially regarding the digestive system. They have a rich chemical composition, responsible for the biological activities demonstrated for the species.

Abstract
Purpose The current study proposed the simple, eco-friendly and cost-effective synthesis of carboxymethyl cellulose (CMC) structured silver-based nanocomposite (CMC-AgNPs) using Syzygium aromaticum buds extract. Methods The CMC-AgNPs were characterized by ultraviolet (UV) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transmission infra-red (FTIR), energy-dispersive X-ray (EDX), and dynamic light scattering (DLS) techniques. The synthesized nanocomposites were evaluated for their bactericidal kinetics, in-vivo anti-inflammatory, anti-leishmaniasis, antioxidant and cytotoxic activities using different in-vitro and in-vivo models. Results The spherical shape nanocomposite of CMC-AgNPs was synthesized with the mean size range of 20–30 nm, and the average pore diameter is 18.2 nm while the mean zeta potential of −31.6 ± 3.64 mV. The highly significant (P < 0.005) antibacterial activity was found against six bacterial strains with the ZIs of 24.6 to 27.9 mm. More drop counts were observed in Gram-negative strains after 10 min exposure with CMC-AgNPs. Significant damage in bacterial cell membrane was also observed in atomic force microscopy (AFM) after treated with CMC-AgNPs. Nanocomposite showed highly significant anti-inflammatory activity in cotton pellet induced granuloma model (Phase I) in rats with the mean inhibitions of 43.13% and 48.68% at the doses of 0.025 and 0.05 mg/kg, respectively, when compared to control. Reduction in rat paw edema (Phase II) was also highly significant (0.025 mg/kg; 42.39%; 0.05 mg/kg, 47.82%). At dose of 0.05 mg/kg, CMC-AgNPs caused highly significant decrease in leukocyte counts (922 ± 83), levels of CRP (8.4 ± 0.73 mg/mL), IL-1 (177.4 ± 21.3 pg/mL), IL-2 (83.7 ± 11.5 pg/mL), IL-6 (83.7 ± 11.5 pg/mL) and TNF-α (18.3 ± 5.3 pg/mL) as compared to control group. CMC-AgNPs produced highly effective anti-leishmaniasis activity with the viable Leishmania major counts decreased up to 36.7% within 24 h, and the IC50 was found to be 28.41 μg/mL. The potent DPPH radical scavenging potential was also observed for CMC-AgNPs with the IC50 value of 112 μg/mL. Furthermore, the cytotoxicity was assessed using HeLa cell lines with the LC50 of 108.2 μg/mL. Conclusion The current findings demonstrate positive attributes of CMC fabricated AgNPs as a promising antibacterial, anti-inflammatory, anti-leishmaniasis, and antioxidant agent with low cytotoxic potential.

Abstract
Introduction. This study aims to evaluate the antinociceptive activity on inflammatory and non-inflammatory nociception models, as well as the anti-inflammatory action of hesperidin and its inclusion compounds with beta-cyclodextrin and hydroxypropyl-beta-cyclodextrin. Material and method. For these experiments, we employed nociception models using thermal, chemical and pressure stimuli and an inflammation model for the evaluation of inflammatory edema by plethysmometer test. Results and discussions. The obtained results demonstrate that the HES-βCD inclusion compounds exhibited antinociceptive action predominantly on experimental non-inflammatory nociception models, while HES-HP-βCD exhibited anti-inflammatory and antinociceptive activities predominantly in inflammatory nociception models. Conclusions. This research may be the starting point for future studies regarding the improvement of biopharmaceutical qualities of HES by encapsulation in cyclodextrins.

[PMID: 30552992 DOI: 10.1016/j.jep.2018.12.015] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/09/2018] [Revised: 12/05/2018] [Accepted: 12/11/2018] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Emex spinosa (L.) Campd. (E. spinosa) locally known as "hillaioua" has always been used in folk medicine for the treatment of inflammation and pain. It is still being exploited by pharmaceutical companies for its potential remedial effects. AIM OF THE STUDY In this study, the effects of E. spinosa (L.) Campd. against acute inflammation, pain and oxidative damage were evaluated. MATERIALS AND METHODS Total phenols and flavonoids were evaluated. Anti-inflammatory and analgesic activities the E. spinosa ethyl acetate fractions of the aerial (Es EtOAc-AP) and underground (Es EtOAc-R) parts were assessed on carrageenan-induced paw oedema (100 mg/kg BW) and acetic acid-induced writhing response (50, 100 and 150 mg/kg BW), respectively. The E. spinosa fractions effects on oxidative stress markers and inflammatory parameters were determined. Gas chromatography-mass spectrometry (GC-MS) analysis was performed to identify various chemical components. RESULTS The ethyl acetate fractions were shown to be the most active thanks to their phenolic and flavonoid contents richness. Intraperitoneal administration of E. spinosa ethyl acetate fractions at 100 mg/kg BW, one hour before carrageenan injection, significantly inhibited the oedema formation by 89.31% and 97.7% for the aerial and underground parts respectively when compared to the reference drug "dexamethasone" (51.9%). Besides, a significant increase (p ≤ 0.001) of the dermal antioxidant enzymes (the superoxide dismutase (SOD)), catalase (CAT) and glutathione peroxidase (GPx) was observed five hours after carrageenan administration. The best restoration was obtained with Es EtOAc-R (82.04%, 93.55% and 93.55% respectively for SOD, CAT and GPx activities). Moreover, EtOAc-fractions treated mice proved their ability to restore both of CRP and fibrinogen (p < 0.001). In addition, E. spinosa EtOAc-fractions attenuated abdominal contractions (p < 0.05) by 71.69% and 82.41% for the aerial part and roots respectively at 150 mg/kg BW against 100% for dichlofenac sodium used as standard drug. The phytochemical analysis of Es EtOAc-AP and Es EtOAc-R by GC-MS may explain the obtained results. The analysis of the fractions demonstrated the presence of palmitic and linoleic acids known for their anti-inflammatory and analgesic capacities. CONCLUSIONS These findings explain the traditional use of E. spinosa in folk medicine and suggest that E. spinosa fractions could be a promising herbal drug.

Abstract
Chinar (Platanus orientalis L.) is used in folk medicine against tooth and knee pain, wounds, inflammation, and stomach discomfort; however, the effects of P. orientalis leaf (PO-leaf) infusion on the liver and kidney are unknown. The aim of this study was to investigate the phytochemical composition and antioxidant properties of an infusion obtained from dried P. orientalis leaves against ethanol-induced oxidative stress (OS) in rats. After a toxicity test, thirty male Wistar rats were divided into five groups: Control, Ethanol 20%, Ethanol 20% + Silymarin (10 mg/kg), Ethanol 20% + PO-20 mg/mL infusion, and Ethanol 20% + PO-60 mg/mL infusion. The PO-leaf infusion doses were given ad libitum during 28 days to test the biochemical and antioxidant enzyme levels. According to the results, the PO-leaf contained rich compounds such as benzaldehyde, palmitic acid, 2,4-ditert-butylphenol, stearic acid, octadecanoic acid, linoleic acid, linolenic acid, kaempferol, and kaempferol derivatives. In the Ethanol group, AST, ALT, LDH, GGT, UA, and urea in the serum and GST and malondialdehyde (MDA) in the liver and erythrocyte tissues showed a significant increase compared to the Control group. AST, LDH, GGT, UA, and LDL-C levels in the serum and MDA (all tissues) significantly decreased in the Ethanol + PO-60 mg/mL group compared to the Ethanol group. SOD, GPx, and CAT activities in the kidney tissue of the Ethanol group showed a significant decrease compared to the Control group, whereas the GPx activity in kidney tissue in all of the treatment groups increased significantly compared to the Ethanol group. These findings suggest that the administration of the determined PO-leaf infusion doses might have a protective role against ethanol-induced liver and kidney damage in rats.

Abstract
CONTEXT Inflammatory disorders are common in modern life, and medicinal plants provide an interesting source for new compounds bearing anti-inflammatory properties. In this regard, Brazilian medicinal plants are considered to be a promising supply of such compounds due to their great biodiversity. OBJECTIVES To undertake a review on Brazilian medicinal plants with corroborated anti-inflammatory activities by selecting data from the literature reporting the efficacy of plants used in folk medicine as anti-inflammatory, including the mechanisms of action of their extracts and isolated compounds. METHODS A search in the literature was undertaken by using the following Web tools: Web of Science, SciFinder, Pub-Med and Science Direct. The terms 'anti-inflammatory' and 'Brazilian medicinal plants' were used as keywords in search engine. Tropicos and Reflora websites were used to verify the origin of the plants, and only the native plants of Brazil were included in this review. The publications reporting the use of well-accepted scientific protocols to corroborate the anti-inflammatory activities of Brazilian medicinal plants with anti-inflammatory potential were considered. RESULTS We selected 70 Brazilian medicinal plants with anti-inflammatory activity. The plants were grouped according to their anti-inflammatory mechanisms of action. The main mechanisms involved inflammatory mediators, such as interleukins (ILs), nuclear factor kappa B (NF-κB), prostaglandin E2 (PGE2), cyclooxygenase (COX) and reactive oxygen species (ROS). CONCLUSIONS The collected data on Brazilian medicinal plants, in the form of crude extract and/or isolated compounds, showed significant anti-inflammatory activities involving different mechanisms of action, indicating Brazilian plants as an important source of anti-inflammatory compounds.

Abstract
The physiological consequences of COX-2 overexpression in the development of cancer, diabetes and neurodegenerative diseases have made this enzyme a promising therapeutic target. Herein, COX-2 active site was analyzed and new molecules were designed. We identified a highly potent molecule (S)-3a with IC50 value and the selectivity for COX-2 0.6 nM and 1666, respectively. The MTD of (S)-3a was 2000 mg kg-1 and its pharmacokinetic studies in rat showed t1/2 7.5 h. This compound reversed acetic acid induced analgesia and carragennan induced inflammation by 50% and 25% in rat when used at a dose 10 mg kg-1. Mechanistically, it was found that compound (S)-3a inhibits COX-2. Overall, the combination of physico-chemical and biological experiments facilitated the development of a new lead molecule to anti-inflammatory drug.

Abstract
The present study deals with the chemical composition and antinociceptive effects of Plinia edulis fruit peels, analyzed by writhing, formalin, glutamate and capsaicin tests and comparison with two reference analgesic drugs, acetylsalicylic acid and acetaminophen. Phytochemical analyses of the nonpolar fraction (dichloromethane) obtained from the peels of P. edulis fruits revealed the presence of two triterpenes, maslinic acid and ursolic acid. The methanol extract of P. edulis peels showed a pronounced antinociceptive activity in the writhing test, with inhibition of 91.3% at 10 mg/kg, and its dichloromethane and ethyl acetate fractions presented inhibition of 68.3% and 51.5%, respectively. Maslinic acid showed a dose-dependent effect with inhibition of 60.8% at a dose of 10 mg/kg and ID50 value of 3.31 (2.75 to 4.0) mg/kg. The dichloromethane fraction, evaluated in the formalin-induced pain model at a dose of 10 mg/kg, showed a significant effect on both phases of pain. Maslinic acid was evaluated at different doses (1, 3 and 6 mg/kg) and presented a dose-dependent profile in both phases of pain, being more effective than the reference drug (acetaminophen), which was evaluated at 10 mg/kg. The dichloromethane fraction also inhibited the pain induced by glutamate and capsaicin by around 54% and 44%, respectively, whereas maslinic acid was more effective against glutamate, with 62.5% inhibition at 6 mg/kg, and 32% inhibition against capsaicin-induced pain. The results demonstrated that the pronounced antinociceptive effect presented by P. edulis fruits peels is related, at least in part, to the presence of the triterpenes evidenced in this study.

Abstract
Background and Purpose:Polygonum orientale L. (family: Polygonaceae), named Hongcao in China, is a Traditional Chinese Medicinal and has long been used for rheumatic arthralgia and rheumatoid arthritis. However, no pharmacological and mechanism study to confirm these clinic effects have been published. In this investigation, the anti-inflammatory, analgesic effects and representative active ingredient compounds of P. orientale have been studied. Methods: Dried small pieces of the stems and leaves of P. orientale were decocted with water and partitioned successively to obtain ethyl acetate and ethyl ether extract of P. orientale (POEa and POEe). Chemical compositions of them were analyzed by UPLC-Q-Exactive HRMS. Anti-inflammatory and analgesic effects of POEa and POEe were evaluated using xylene induced ear edema, carrageenan induced paw edema, Freunds' complete adjuvant induced arthritis, and formaldehyde induced pain in rat. Their mechanisms of anti-inflammatory and analgesic effects were also studied via assays of TNF-α, IL-1β, IL-6, and PGE2 in serum. Results: UPLC-Q-Exactive HRMS analysis showed that POEa and POEe mainly contained flavonoids including orientin, isoorientin, vitexin, luteolin, and quercetin. Furthermore, anti-inflammatory effects of POEa and POEe were evident in xylene induced ear edema. The paw edema in Freund's complete adjuvant and carrageenan were significantly (P < 0.05, 0.01) inhibited by POEa (5, 7.5 g/kg). POEe (7.5 g/kg) was significantly (P < 0.05, 0.01) inhibited Freunds' complete adjuvant induced paw edema and cotton pellet induced granuloma formation. Similarly, POEe significantly (P < 0.05, 0.01) inhibited the pain sensation in acetic acid induced writhing test. POEa (5, 7.5 g/kg) significantly (P < 0.05, 0.01) inhibited formaldehyde induced pain in both phases. POEa (7.5 g/kg) markedly (P < 0.05) prolonged the latency period of hot plate test after 30 and 60 min. The concentrations of TNF-α, IL-1β, IL-6, and PGE2 were significantly (P < 0.01) decreased by POEa (3.75, 5 g/kg). Conclusion: POEa and POEe have anti-inflammatory and analgesic effects, which was mainly relevant to the presence of flavonoids, including orientin, isoorientin, vitexin, luteolin, and quercetin. The mechanism of anti-inflammatory and analgesic effects of POEa may be to decrease the concentrations of TNF-α, IL-1β, IL-6, and PGE2 in serum.
