Abstract
Aim The use of medicinal plants in the treatment of mental illnesses is a reality that accompanies the history of civilizations, and the Piper genus exhibits many species with pharmacologically proven central effects. Then, this study evaluated the neuropharmacological effects of the hydroalcoholic extract from Piper cernuum (HEPC) leaves to validate its uses in folk medicine. Materials and Methods Primarily Swiss mice (female, 25-30 g) were pretreated with HEPC (50-150 mg/kg, p.o.), vehicle, or the positive control, and submitted to open-field test (OFT), inhibitory avoidance test (IAT), tail suspension test (TST), and forced swim test (FST). Also, mice were exposed to pentylenetetrazol- and strychnine-induced seizure assay, pentobarbital-induced hypnosis test, and elevated plus-maze (EPM). The GABA levels and MAO-A activity were measured in the animal's brain after 15 days of HEPC administration (150 mg/kg, p.o.). Results Mice pretreated with HEPC (100 and 150 mg/kg) and exposed to pentobarbital presented decreased sleep latency and increased sleep duration (HEPC 150 mg/kg). In EPM, the HEPC (150 mg/kg) increased the frequency of entry and the time of exploration of mice in the open arms. The antidepressant-like properties of HEPC were demonstrated by the decrease in the mice's immobility time when tested in FST and TST. The extract did not show anticonvulsant activity, in addition to not improving the memory parameters of animals (IAT) or interfering with their locomotor activity (OFT). Besides, HEPC administration decreased the MAO-A activity and increased the GABA levels in the animal's brain. Conclusion HEPC induces sedative-hypnotic, anxiolytic-, and antidepressant-like effects. These neuropharmacological effects of HEPC could be, at least in part, related to the modulation of the GABAergic system and/or MAO-A activity.

Abstract
AIMS Major depressive disorder (MDD) affects approximately 322 million people worldwide and is a common comorbidity in patients with diabetes mellitus (DM). A possible pathophysiological mechanism correlating both diseases is the increased oxidative stress in brain regions due to hyperglycemia. Myrsine coriacea (Primulaceae) is popularly known as "capororoca" and studies have been shown that this plant exhibits several pharmacological properties attributed to myrsinoic acid A (MAA) and B (MAB). Indeed, previous results have been shown its effects on the central nervous system, leading us to explore possible psychotropic effects. MAIN METHODS The effects of treatment with hydroalcoholic extract of the barks from Myrsine coriacea (HEBMC, 150 mg/kg, o.g.), MAA (5 mg/kg, o.g.), and MAB (3 mg/kg, o.g.) were evaluated in streptozotocin (75 mg/kg, i.p.)-induced diabetic female rats. After 28 days of treatments, rats were submitted to the forced swim test (FST) and open field test (OFT). Also, superoxide dismutase (SOD) and catalase (CAT) activities, reduced glutathione (GSH) and lipid hydroperoxides (LOOH) levels were evaluated in the hippocampus (HIP) and prefrontal cortex (PFC) of these rats. KEY FINDINGS The treatment with MAA or MAB increased the latency of first immobility in diabetic rats, and the HEBMC administration decreased the immobility time, and increase the climbing in FST. However, only MAB treatment reduces the immobility time, increases the climbing, and swimming in FST, and increases the crossing of diabetic animals in the OFT. Besides, this behavioral improvement promoted by MAB administration was accompanied by reducing in oxidative stress in the HIP and PFC, but not reducing hyperglycemia in diabetic rats. SIGNIFICANCE The results suggest that MAB's antioxidant effect in the HIP of diabetic animals may be essential to its antidepressant-like effect.

Abstract
Plumieride (PLU), an iridoid isolated from Allamanda cathartica flowers, has been studied by our research group due to its anti-inflammatory potential, antidepressant-like and anxiolytic-like effects. This research investigated the involvement of GABAergic and monoaminergic systems in the anxiolytic-like effect elicited by PLU. Therefore, mice were pre-treated with GABAergic, serotonergic, adrenergic or dopaminergic receptor antagonists (i.p.), and exposed to Elevated Plus-Maze (EPM) and Open-Field Test (OFT). The preliminary results revealed that PLU (p.o.) possibly interacts with the mentioned systems through the GABAA, GABAB, 5-HT1A, 5-HT3, α1, α2, and D2 receptors.

Abstract
INTRODUCTION Eugenia umbelliflora fruits are an important source of phloroglucinols, as eugenial C and eugenial D, related to antimicrobial activity against Staphylococcus aureus. However, for the establishment of new antimicrobial substances, it is essential to know their stability profile, in view of driving the administration route and the release system development. METHODOLOGY The in silico approaches, based on the Fukui indices and bond dissociation analysis, were performed. Eugenial C and eugenial D, isolated from the green fruits of E. umbelliflora, with purity > 90%, were submitted to stress degradation including: acid (0.5 mM hydrochloric acid) and alkaline (0.5 mM sodium hydroxide) hydrolysis, and oxidation (0.25% hydrogen peroxide), in different periods, monitoring by high-performance liquid chromatography with ultraviolet detector (HPLC-UV). Eugenial C was also submitted to UV-visible radiation (2,400 lux/h) and dry/humid heating (40°C, 75% relative humidity). RESULTS In silico studies indicated that both molecules have regions of high susceptibility to nucleophilic and electrophilic attack as well as sites likely to suffer auto-oxidation. Under in vitro tests, both phloroglucinols proved to be very unstable under hydrolysis (eugenial C and D were degraded 23.8% and 89.0% in acid and 78.4% and 97.8% in alkaline conditions, respectively) and oxidation (eugenial C and D degraded 31.9% and 28.6%, respectively), both during 5 min. Eugenial C degraded 12.6% and 63.8% under dry and humid heat, respectively, without photosensitivity. CONCLUSION The in vitro stress tests monitored by HPLC-UV were in agreement with in silico degradation prediction. Phloroglucinols could be unstable if administered by oral route and also under environmental conditions demanding a protective release system.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tithonia diversifolia (Helms.) A. Gray, popularly known in Brazil as "margaridão" or "mão-de-Deus" has been used in the folk medicine as anti-inflammatory and against other illnesses in several countries. Indeed, many studies show de effect of T. diversifolia in the inflammatory process, however, any of them have demonstrated the mechanism of cell migration. AIM OF THE STUDY The aim of this investigation was to show the in vivo and in vitro effects of T. diversifolia leaves ethanol extract on neutrophil trafficking from the blood to the inflamed tissue and on cell-derived secretion of chemical mediators, as well as, the effects on inflammatory resolution and inflammatory pain. MATERIALS AND METHODS Anti-inflammatory activity was investigated using carrageenan-induced inflammation in the subcutaneous tissue of male Swiss mice orally treated with the T. diversifolia extract (0.1, 1 or 3 mg/kg). The leukocyte influx (optical microscopy) and the secretion of chemical mediators (TNF, IL-6, IL-1β and CXCL1, by enzyme-linked immunosorbent assay) were quantified in the inflamed exudate. Histological analysis of the pouches was performed. N-Formyl-methionine-leucine-phenylalanine-induced chemotaxis, lipopolysaccharide-induced TNF, IL-6, IL-1β, CXCL1 and NO production, and adhesion molecule expression (CD62L and CD18, flow cytometry) were in vitro quantified using oyster glycogen recruited peritoneal neutrophils previous treated with the extract (1, 10, or 100 μg/mL). The resolution of inflammation was accessed by efferocytosis assay, and the antinociceptive activity was investigated using carrageenan-induced mechanical hypersensitivity. RESULTS The oral treatment with T. diversifolia promoted reduction in the neutrophil migration as well as the decrease in total protein, TNF, IL-1β and CXCL1 levels in the inflamed exudate. In vitro treatment with T. diversifolia shedding of β2 integrin expressions, without alter CD62L expression. The extract was able to increase the efferocytosis of apoptotic neutrophils, and the increase of the IL-10 and the decrease of TNF secretion. Additionally, the extract reduced the hypersensitivity induced by carrageenan. CONCLUSIONS Together, the data herein obtained showed that T. diversifolia extract presented anti-inflammatory activity by inhibiting the cytokine and NO production, and also the leukocyte migration. The mechanisms involved in the extract anti-inflammatory effects include the impairment in the leukocyte migration to the inflamed tissue, the pro-resolution activity, and consequently the anti-hypersensitivity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Piper cernuum Vell (Piperaceae) is a native species from Atlantic rain forest, popularly known as pariparoba. Its leaves have been commonly used by rural and urban communities from State of São Paulo, Brazil, to treat pain (orally and topically), and hepatic and renal complications. AIM OF THE STUDY In this study we evaluated the acute and sub-acute toxicity, genotoxicity and mutagenicity of hydroalcoholic extract obtained from P. cernuum leaf using in vivo and in vitro methods. MATERIAL AND METHODS In the acute toxicity study, mice were orally treated with P. cernuum extract (2000 mg/kg, p.o.). General behavior and mortality were observed for up to 14 days. In the sub-acute toxicity study, P. cernuum extract was given orally as a single administration to the rats at doses of 50 or 250 mg/kg/day, for 28 days. General behavior, body weight, biochemical and hematological parameters, organ coefficients and pathological morphology were analyzed. The P. cernuum mutagenicity was evaluated using mammalian cell micronucleus assay. Additionally, in vitro toxicity profile of the extract was assessed through cytotoxicity, hemolytic activity, and genotoxicity assay. RESULTS Data from comet assay demonstrates that high concentrations of P. cernuum extract induce genotoxicity. However, no evidence of hemolytic, cytotoxic or mutagenicity activity was found. In addition, the acute and sub-acute toxicity studies did not show significant changes in body weight, general behavior, hematology and biochemical parameters, organ weight and liver and kidney histopathological analysis. CONCLUSIONS Together, the results herein obtained indicate that P. cernuum leaves extract did not present significant toxicity when administered to male or female rats. Additionally, no significant alteration in hematological, biochemical and morphological parameters were observed. Data obtained in vitro shows that extract did not present cytotoxicity and mutagenicity. However, the extract induces in vitro genotoxicity, but in high concentration. Further studies are necessary to evaluate the safety of long-term exposure to P. cernuum leaves extract added to in vivo genotoxicity.

Abstract
The aim of this study was to develop nanoemulsion containing soft extract of stem bark of Rapanea ferruginea to improve the topical delivery and anti-inflammatory activity. The extract of R. ferruginea stem bark was incorporated into the oily phase of the nanoemulsion by the method of phase inversion at low energy. The developed nanoemulsion had an average droplet size of 47.88±8.20 nm and a polydispersibility index of 0.228. Uniformity of size, spherical shape of droplet, and absence of clusters were confirmed by transmission electronic microscopy. The zeta potential was -34.7±1.15 mV. The nanoemulsion showed a moderate degree of skin irritation in the agarose overlay assay in vitro. The content of the extract markers, myrsinoic acids A and B, was 54.10±0.08 and 53.03 μg/g in the formulation, respectively. The formulation demonstrated pseudoplastic and thixotropic rheological behavior. In vitro release of chemical markers was controlled by diffusion mechanism. An extract-loaded nanoemulsion showed a topical anti-inflammatory activity in a croton oil-induced edema ear model, with a decrease in tumor necrosis factor release and myeloperoxidase activity. The nanoemulsion was 160% more efficient than the conventional cream containing 0.13% of the extract. The nanoemulsion showed suitable properties as a carrier for topical use of R. ferruginea extract and the approach for improving the topical anti-inflammatory activity.

Abstract
Drimys brasiliensis Miers (Winteraceae) is used in folk medicine for the treatment of cancer. Its anti-tumor activity has been demonstrated in vitro models using extracts and isolated compounds. This study investigates the cytotoxic effects of stem bark extracts of D. brasiliensis as well as isolated compounds that may be responsible for the activitys and evaluates them in leukemia cells. The stem bark extract were subjected to column chromatography, and the structures of compounds were elucidated based on spectroscopic methods by using NMR and infrared spectroscopy and GC/MS. The cytotoxicity of the isolated compounds was evaluated in chronic myeloid (K562) and acute B lymphoblastic (Nalm6) leukemia cells using tetrazolium assay (MTT). Two new compounds were isolated 1β-O-p-methoxy-E-cinnamoyl-5α-keto-11α-enol-albicanol (1a) and the isomer 1β-O-p-methoxy-E-cinnamoyl-5α-keto-11β-enol-albicanol (1b) and 1β-O-p-methoxy-E-cinnamoyl-isodrimeninol (2). The known compounds polygonal acid (3a) and the isomer isopolygonal acid (3b), fuegin (4a) and the isomer epifuegin (4b), the mixture drimanial (5) and 1β-O-(p-methoxy-E-cinnamoyl)-6α-hydroxypolygodial (6) were also isolated. The drimanes (1-4) and drimanial (5), 1β-(p-coumaroyloxy)-polygodial (7), 1β-(p-methoxycinnamoyl)-polygodial (8), and polygodial (9) isolated previously were assessed in tumor cells. The IC50 values were between 3.56 and 128.91 μM. 1-β-(p-cumaroiloxi)-polygodial showed the best result with IC50 8.18 and 3.56 μM by K562 and Nalm6, respectively. The chloroform extract of the stem bark of D. brasiliensis is a great source of drimane sesquiterpenes. Our experimental data suggest that drimanes are responsible for cytotoxicity activity demonstrated by this species, especially those with the aldehyde group linked to carbons C-11 and C-12.

Abstract
The present work describes the antinociceptive properties and chemical composition of the aerial parts of Plinia glomerata (Myrtaceae). Both of the extracts evaluated, acetonic and methanolic, showed potent antinociceptive action, when analyzed against acetic acid-induced abdominal constrictions in mice, with calculated ID50 (mg/kg, i. p.) values of 24.8 and 3.3, respectively. Through usual chromatographic techniques with an acetonic extract, the following compounds were obtained: 3,4,3′-trimethoxy flavellagic acid (1), 3,4,3′-trimethoxy flavellagic acid 4′-O-glucoside (3) and quercitrin (4), which were identified based on spectroscopic data. Compounds 1 (ID50 = 3.9 mg/kg, i. p., or 10.8 μmol/kg) and 3 (ID50 = 1.3 mg/kg or 2.5 μmol/kg) were notably more active than some well-known analgesic drugs used here for comparison.

Abstract
This paper evaluates CHCl3 and CH3OH extracts of the stem bark, branches and leaves of Drimys brasiliensis and drimane sesquiterpenes isolated from the stem bark against strains of Leishmania amazonensis and Leishmania braziliensis promastigotes and Plasmodium falciparum trophozoites. All of the extracts and compounds were tested in cell lines in comparison with reference standards and cell viability was determined by the XTT method. The CHCl3 and CH3OH extracts from the stem bark and branches yielded promising results against two strains of Leishmania, with 50% inhibitory concentrations (IC50 ) values ranging from 39-100 µg/mL. The CHCl3 extract of the stem bark returned IC50 values of 39 and 40.6 µg/mL for L. amazonensis and L. braziliensis, respectively. The drimanes were relatively effective: 1-β-(p-coumaroyloxy)-polygodial produced IC50 values of 5.55 and 2.52 µM for L. amazonensis and L. braziliensis, respectively, compared with 1-β-(p-methoxycinnamoyl)-polygodial, which produced respective IC50 values of 15.85 and 17.80 µM. The CHCl3 extract demonstrated activity (IC50 of 3.0 µg/mL) against P. falciparum. The IC50 values of 1-β-(p-cumaroyloxyl)-polygodial and 1-β-(p-methoxycinnamoyl)-polygodial were 1.01 and 4.87 µM, respectively, for the trophozoite strain. Therefore, the results suggest that D. brasiliensis is a promising plant from which to obtain new and effective antiparasitic agents.

Abstract
UNLABELLED ETHNO-PHARMACOLOGICAL RELEVANCE: Chenopodium ambrosioides (Amarantaceae) is an annual or perennial plant popularly known as 'erva de Santa Maria', 'mastruço' and 'erva-do-formigueiro'. This herb is used in folk medicine in the form of teas, poultices and infusions for inflammatory problems, contusions and lung infections, and as an anthelmintic and anti-fungal. AIM OF THE STUDY The aim of the present study was to further the understanding of the anti-nociceptive, anti-inflammatory and wound healing effects of ethanol extract (EE) obtained from the leaves and stems of Chenopodium ambrosioides in animal models of acute pain, inflammation and wound healing, thus supporting its medicinal use for the treatment of pain and inflammatory conditions MATERIALS AND METHODS The anti-nociceptive activity of EE (150-500 mg/kg) was evaluated using the nociception induced by formalin (2.5%), prostaglandin-E(2) (PGE2; 3 nmol/paw), capsaicin (CAP, 1.6 μg/paw) and bradykinin (BK, 10 nmol/paw). The anti-inflammatory activity of EE (150-500 mg/kg) was evaluated in carrageenan- (Cg, 300 μg/paw), PGE(2)- (3 nmol/paw), substance P- (SP, 20 nmol/paw) and BK- (3 nmol/paw) induced paw oedema. The topical anti-inflammatory activity of EE (1%, 3% and 5%) was evaluated in arachidonic acid- (AA, 2mg/ear), oil croton- (1 μg/ear) and CAP- (250 μg/ear) induced ear oedema. The effect of this extract in the inhibition of the influx of neutrophil, myeloperoxidase (MPO) and adenosine-deaminase (ADA) activities and nitric oxide (NO) and TNF-á levels was also determined using the mouse of pleurisy induced by Cg. The excision wound model in rats was used to evaluate the wound healing efficacy of EE (1%, 3% and 5%). To exclude the possible non-specific muscle relaxant or sedative effects of EE, mice motor performance was also evaluated with the rota-rod test. RESULTS EE (5% per ear) was effective in reducing ear oedema induced by croton oil by 78.09%, CAP by 70.85% and AA by 77.02%. EE (500 mg/kg; p.o.) also significantly inhibited paw oedema induced by Cg by 40%, PGE(2) by 51%, SP by 56% and BK by 57%. EE (500 mg/kg; p.o.) inhibited the cell influx of leucocytes by 78% and neutrophils by 53%, MPO activity by 62.22% and ADA activity by 23.07%, as well as NO by 77.77% and TNF-á levels by 50% in the fluid leakage due to the carrageenan-induced pleurisy. EE also inhibited the formalin-induced nociceptive in both phases of pain (neurogenic and inflammatory) at a dose of 500 mg/kg, resulting in inhibitions of 77.39% and 95.60%, respectively. EE (500 mg/kg; p.o.) was also effective in inhibiting the nociception induced by PGE(2) (68%), CAP (53%) and BK (32%). Topical application of EE (5%) on excision wounds caused a significant reduction in wound area when compared with the untreated controls. Finally, treatment with EE (150-500 mg/kg) did not show any significant alterations in motor performance or body temperature compared with the control group. CONCLUSIONS The results, including the inhibition of mediators (BK, NO, SP, PGE(2) and TNF-á) and enzyme (MPO and ADA) activity, validate the use of the plant under study for therapeutic treatment of anti-inflammatory, painful and wound healing processes.

Abstract
Myrsinoic acid B (AMB) is a prenylated-benzoic acid derivative isolated from the Rapanea genus. Recent studies suggest that AMB has antihyperalgesic and antinociceptive properties in different animal models. The present study was designed to investigate the mechanisms involved in antinociception elicited by AMB (60 mg/kg) when administered by intraperitonial route (i.p.) in mice. The antinociceptive response of the compound was characterized by a reduction in contractions of the abdominal muscle, together with stretching of the hind limbs in response to i.p. injection of acetic acid (0.6%, 0.45 ml/mouse). The antinociception caused by AMB in the acetic acid test was significantly attenuated by i.p. treatment of mice with nitric oxide precursor, (L-arginine, 600 mg/kg), alpha2 and alpha1-adrenoceptor antagonists (yohimbine, 0.2 mg/kg/prazosin, 0.2 mg/kg), p-chlorophenylalanine (PCPA) an inhibitor of serotonin synthesis (100 mg/kg), 1-(2-methoxyphenyl)-4-(4-phthalimidobutyl)piperazine (NAN 190), a 5-HT1(A) selective receptor antagonist (0.5 mg/kg) and a non-selective cholinergic antagonist (atropine, 10 mg/kg). Its action was also modulated by the adrenal-gland hormones. In contrast, antinociception was not affected by naloxone (non-selective opioid receptor antagonist, 1.0 mg/kg), phaclofen (2.0 mg/kg) and bicuculline (1.0 mg/kg) GABA(B) and GABA(A) receptor antagonists, respectively, ondansetron (0.3 mg/kg) and ketaserin (1.0 mg/kg), (5-HT3 and 5-HT2 receptors, respectively) and haloperidol (0.2 mg/kg), a non-selective dopaminergic receptor. The antinociceptive effects are not related to muscle-relaxant or sedative action. These results indicate that AMB produces antinociception through mechanisms that involve interaction with L-arginine-nitric oxide, the serotonergic and cholinergic systems, as well as interaction with the alpha-adrenoceptors.

Abstract
A new triterpene 3,15-dioxo-21alpha-hydroxy friedelane has been isolated from methanol extract of Maytenus robusta and its structure elucidated on the basis of spectral analysis. Stigmasterol, friedelin, friedelanol and 3,15-dioxo friedelane were also obtained. 3,15-dioxo-21alpha-hydroxy friedelane was analyzed against the writhing test in mice and exhibited potent dose-dependent effects with an ID50 value of 12.5 +/- 2.1 micromol kg(-1) and a maximal inhibition of 85.90%. It was about 10-fold more active than aspirin and paracetamol, used as reference drugs.

Abstract
This study was designed to assess the participation of transient receptor potential vanilloid 1 (TRPV1) in the biological effects induced by the plant-derived sesquiterpenes polygodial and drimanial. In rat isolated urinary bladder, polygodial and drimanial produced a tachykinin-mediated contraction that was inhibited by combination of NK(1) and NK(2) tachykinin receptor antagonists, SR 140333 and SR 48968. Furthermore, two different TRPV1 antagonists, capsazepine and ruthenium red prevented the contraction induced by both compounds. In addition, capsaicin, polygodial and drimanial displaced in a concentration-dependent manner the specific binding sites of [(3)H]-resiniferatoxin to rat spinal cord membranes, with a IC(50) values of 0.48, 4.2 and 3.2 microM, respectively. Likewise, capsaicin, polygodial and drimanial promoted an increase of [(45)Ca(2+)] uptake in rat spinal cord synaptosomes. In cultured rat trigeminal neurons, polygodial, drimanial and capsaicin were also able to significantly increase the intracellular Ca(2+) levels, effect that was significantly prevented by capsazepine. Together, the present results strongly suggest that the pharmacological actions of plant-derived sesquiterpenes polygodial and drimanial, seem to be partially mediated by activation of TRPV1. Additional investigations are needed to completely define the pharmacodynamic properties of these sesquiterpenes.

Abstract
PURPOSE To investigate the anti-proliferative effect of A. blanchetti and A. schottii extracts. METHODS The anti-proliferative effect of A. blanchetti and A. schottii ethanolic extracts on K562 leukemic cells as well as on BMEC and HUVEC were evaluated. Phytochemical analysis to identify the possible active components was carried out. RESULTS The root extract of A. schottii was the most active of them. At 80 microg/mL, the root extracts showed a cytostatic effect on K562, whereas at 400 microg/mL, there was a strong cytotoxic effect. Similar cytostatic and cytotoxic effects were seen in the endothelial cells, but at lower doses. The effect of A. schottii root extract on endothelial cells was seen at concentrations ten times lower (8 microg/mL) than the effect of the A. blanchetti root extract (80 microg/mL). Phytochemical investigation of different fractions and parts of the plant led to the isolation of several known compounds, some of which are described for the first time in the genus Allamanda, and with previous evidence of anticancer and antitumoral properties. CONCLUSIONS Our results suggest that both plants studied exhibit cytostatic and cytotoxic activity, but the most active compounds are located in the roots.

Abstract
PURPOSE This study describes the antifungal effect of extracts and compounds isolated from Drimys brasiliensis acting against dermatophytes. METHODS The activities were evaluated by using the microbroth dilution method. RESULTS Bioassay-guided fractionation of the most active extract from the bark (CHCl3) led to the isolation of the sesquiterpene drimanes polygodial, 1-beta-(p-methoxycinnamoyl)-polygodial, drimanial and 1-beta-(p-cumaroyloxy)-polygodial, which were selectively active against Epidermophyton floccosum and Tricophyton rubrum. CONCLUSIONS The selective antifungal activity reported in this paper for drimanes isolated from D. brasiliensis opens the possibility that they could be helpful for the developing of new antifungal agents for treating the difficult to eradicate dermatomycoses produced by E. floccosum.

Abstract
Polygodial is a naturally occurring sesquiterpene dialdehyde that exhibits several pharmacologically interesting activities. Among them, its antifungal properties have been more thoroughly studied. The mitochondrial ATPase has been suggested as one of the possible targets for polygodial action. However, its mechanism of action is not well defined yet. The effect of polygodial on the mitochondrial energy metabolism is described in this paper. Polygodial inhibited ATP synthesis coupled to succinate oxidation in beef-heart submitochondrial particles at concentrations (IC(50)=2.4+/-0.1 microM) which marginally affected electron transport and ATPase activity (IC(50)=97+/-4 microM). A transitory stimulation of the electron transport in intact rat liver mitochondria in state 4 was also obtained at low polygodial concentrations (EC(50)=20+/-4 microM). These results suggest that polygodial uncouples ATP synthesis from electron transport at low concentrations. Similar concentrations of polygodial partially abolished the ANS fluorescence enhancement (IC(50)=2.2+/-0.4 microM) induced by succinate oxidation in submitochondrial particles but did not collapse the DeltapH. We postulate that polygodial uncouples mitochondrial ATP synthesis by affecting the electrical properties of the membrane surface and consequently collapsing the membrane potential (Deltapsi) and/or the localized transmembrane pH difference (DeltapH(S)) without affecting the DeltapH between the two bulk aqueous phases (DeltapH(B)). The relevance of these findings for the understanding of the biochemical basis of the antifungal activity of polygodial and the evaluation of its potentiality as a therapeutic agent are discussed.

Abstract
The mixture of the two pentacyclic triterpenes alpha-amyrin and beta-amyrin, isolated from the resin of Protium kleinii and given by intraperitoneal (i.p.) or oral (p.o.) routes, caused dose-related and significant antinociception against the visceral pain in mice produced by i.p. injection of acetic acid. Moreover, i.p., p.o., intracerebroventricular (i.c.v.), or intrathecal (i.t.) administration of alpha,beta-amyrin inhibited both neurogenic and inflammatory phases of the overt nociception caused by intraplantar (i.pl.) injection of formalin. Likewise, alpha,beta-amyrin given by i.p., p.o., i.t., or i.c.v. routes inhibits the neurogenic nociception induced by capsaicin. Moreover, i.p. treatment with alpha,beta-amyrin was able to reduce the nociception produced by 8-bromo-cAMP (8-Br-cAMP) and by 12-O-tetradecanoylphorbol-13-acetate (TPA) or the hyperalgesia caused by glutamate. On the other hand, in contrast to morphine, alpha,beta-amyrin failed to cause analgesia in thermal models of pain. The antinociception caused by the mixture of compounds seems to involve mechanisms independent of opioid, alpha-adrenergic, serotoninergic, and nitrergic system mediation, since it was not affected by naloxone, prazosin, yohimbine, DL-p-chlorophenylalanine methyl ester, or L-arginine. Interestingly, the i.p. administration of alpha,beta-amyrin reduced the mechanical hyperalgesia produced by i.pl. injection of carrageenan, capsaicin, bradykinin, substance P, prostaglandin E2, 8-Br-cAMP, and TPA in rats. However, the mixture of compounds failed to alter the binding sites of [3H]bradykinin, [3H]resiniferatoxin, or [3H]glutamate in vitro. It is concluded that the mixture of triterpene alpha-amyrin and beta-amyrin produced consistent peripheral, spinal, and supraspinal antinociception in rodents, especially when assessed in inflammatory models of pain. The mechanisms involved in their action are not completely understood but seem to involve the inhibition of protein kinase A- and protein kinase C-sensitive pathways.

Abstract
Protium kleinii (Burseraceae), a native Brazilian medicinal plant is claimed to be useful to treat some inflammatory states. Now we reported that topical application of either the ether extract or the main active constituent from P. kleinii the pentacyclic triterpene alpha-amyrin, all caused a dose-related inhibition of both ear oedema (ID50 values are 0.55 and 0.31 mg/ear, respectively) and influx of polymorphonuclear cells (ID50 values are 0.72 and 0.45 mg/ear, respectively) in response to topical application of 12-O-tetradecanoylphorbol-acetate (TPA) in the of mice ear. In terms of the efficacy, the maximal obtained inhibition for both ear oedema and neutrophil influx was very similar to that produced by the topical application of the steroidal antiinflammatory drug dexamethasone (DE; with inhibition of 70+/-5%, 66+/-3%, and 87+/-4% for oedema and 83+/-6%, 73+/-5%, and 91+/-3% for neutrophil influx, for the ether extract, alpha-amyrin, and dexamethasone, respectively). Likewise, both the ether extract and alpha-amyrin given topically dose-dependently prevented the increase of the proinflammatory cytokine interleukin-1beta levels in response to topical application of TPA. The calculated mean ID50 values are 1.81 and 0.53 mg/ear, respectively. Again, the efficacy of the extract and alpha-amyrin was very similar to that produced by dexamethasone (63+/-6%, 61+/-5%, and 74+/-5%, respectively). In marked contrast to phenidone, a lipo and cyclooxygenase inhibitor, neither the ether extract nor the alpha-amyrin inhibited arachidonic acid-mediated ear oedema in mice. Collectively, these results indicate that the active constituents present in the ether extract of P. kleinii including the pentacyclic triterpene alpha-amyrin are good candidates to develop a skin permeable antiinflammatory drug.

Abstract
This study investigated whether or not the neonatal treatment of rats with the sesquiterpenes polygodial or drimanial could cause persistent antinociception similar to that induced by capsaicin. Rats were injected subcutaneously 48 h after birth with capsaicin (50 mg/kg), polygodial (150 mg/kg), drimanial (150 mg/kg) or vehicle (1ml/kg). Six to eight weeks later, rats were tested in models of nociception. Treatment of rats with capsaicin, polygodial or drimanial produced significant inhibition of the first phase and, to a lesser extent, the second phase of formalin-induced nociception. A significant reduction in Complete Freund's Adjuvant and capsaicin-induced hyperalgesia was observed in the animals neonatally treated with capsaicin, polygodial or drimanial compared with vehicle-treated rats. Moreover, both sesquiterpenes caused inhibition of plasma extravasation induced by injection of capsaicin. The neonatal treatment with capsaicin, polygodial or drimanial significantly decreased [3H]-resiniferatoxin binding sites in the rat spinal cord, but only capsaicin neonatal treatment significantly reduced the expression of TRPV1 in dorsal root ganglia (DRG) when assessed by Western blot. These results extend our previous findings demonstrating that the neonatal treatment of rats with polygodial or drimanial, similar to that reported for capsaicin, produced persistent antinociception in adult animals associated with TRPV1 down-regulation in the spinal cord, but not TRPV1 expression in DRG.

Abstract
This study examines the relaxation produced by the sesquiterpene polygodial and compares its action with those caused by acetylcholine (ACh) and sodium nitroprusside (SNP) in the rabbit corpus cavernosum (RbCC) in vitro. RbCC was set up in a 5-ml bath containing Krebs solution at 37 degrees C, at pH 7.2, and under 2 g of tension. Polygodial, ACh, and SNP elicited graded relaxation in RbCC with mean EC50 values of 46.70 microM, 0.38 microM, and 0.30 microM, respectively. The nitric oxide (NO) synthase inhibitor L-NOARG and the guanylate cyclase inhibitors LY 83583 and ODQ markedly inhibited the relaxation induced by polygodial (% of inhibition of 79, 48, and 51, respectively) and those caused by ACh (% of inhibition of 100, 49, and 32, respectively). Tetraethylammonium (TEA) and glibenclamide inhibited the relaxation induced by polygodial (52% and 43%, respectively), but only TEA caused shift to the right on ACh-mediated relaxation. In contrast, apamin, charybdotoxin, and 4-aminopyridine or the protein kinase A inhibitor KT 5720 all failed to affect either polygodial or ACh-mediated relaxation in these preparations. The authors concluded that polygodial produced graded relaxation in the RbCC in vitro via a mechanism that was partially dependent on the release of NO or a NO-derived substance through an activation of guanylate cyclase but was independent of adenylate cyclase mechanism. In addition, the opening of K+ channels sensitive to TEA and glibenclamide, but not those sensitive to apamin, 4-aminopyridine, or charybdotoxin, also contributed to the relaxant action produced by polygodial in the RbCC.

Abstract
Drimanial, a new sesquiterpene isolated from the barks of the plant Drimys winteri (Winteraceae), given systemically, intraplantarly, or by spinal or supraspinal routes, produced pronounced antinociception against both phases of formalin-induced licking. The systemic injection of drimanial also inhibited, in a graded manner, the pain-related behaviours induced by intraplantar or intrathecal (i.t.) administration of glutamate. Moreover, drimanial also caused marked inhibition of the nociception induced by i.t. administration of a metabotropic glutamate agonist (1S,3R)-ACPD, without affecting nociceptive responses induced by ionotropic agonists (NMDA, kainate, AMPA) or by substance P. The antinociception caused by drimanial was not influenced by naloxone, nor did it interfere with the motor coordination of animals in the rota-rod test. Furthermore, drimanial caused graded inhibition of [(3)H]glutamate binding in cerebral cortical membranes from mice, with an IC(50) value of 4.39 micro M. Together, these results provide strong evidence indicating that the sesquiterpene drimanial produces antinociception in mice at peripheral, spinal and supraspinal sites. An interaction with metabotropic glutamate receptors seems to contribute to the mechanisms underlying its antinociceptive action.

Abstract
This study evaluates further the anti-inflammatory and anti-allergic properties of polygodial, a sesquiterpene extracted from the barks plant Drymis winteri (Winteraceae). Polygodial (12.8-128.1 micromol/kg, i.p.) 30 min prior, inhibited significantly the mouse paw oedema induced by prostaglandin E2, bradykinin (BK) substance P (SP), dextran, platelet activating factor (PAF) or carrageenan. Polygodial also inhibited arachidonic acid-, capsaicin- and croton oil-induced ear oedema in mice. Polygodial (42.7 micromol/kg, i.p.), significantly inhibited both exudation and cell influx when assessed in the pleurisy induced by SP and histamine, and to a less extent the inflammatory response caused by carrageenan, PAF, BK and des-Arg9-BK. Finally, polygodial (4.2-42.7 micromol/kg, i.p.) produced dose-related inhibition of paw oedema induced by ovalbumin, protecting in a time-dependent manner the anaphylactic shock induced by endovenous administration of ovalbumin in animals which had been actively sensitised by this antigen. These and our previous results indicate that the major component present in the bark of the plant D. winteri, the sesquiterpene polygodial exerts an interesting anti-inflammatory and anti-allergic properties when assessed in rats and mice.

Abstract
This study investigates the antinociception caused by i.p. and p.o. administration of ether fraction and the triterpene identified as urs-12-ene-3beta-16beta-diol, known as Brein, isolated from Protium kleinii in several models of nociception in mice. The systemic administration of ether fraction (0.3 to 10 mg/kg, i.p. or 3 to 60 mg/kg, p.o.) caused a dose-related antinociception when assessed against acetic acid-induced writhing, with mean ID50 values of 1.2 and 16.4 mg/kg, respectively. The ether fraction (5 to 60 mg/kg, i.p. or 30 to 300 mg/kg, p.o.) also produced dose-related inhibition of both phases of formalin induced licking. The mean ID50s values for the early phase were > 60.0 and 62.1 mg/kg, while for the late phase they were 15.4 and 60.0 mg/kg, respectively, given by i.p. and p.o. routes. The ether fraction (3 to 30 mg/kg, i.p. or 10 to 100 mg/kg, p.o.) produced significant inhibition of the neurogenic nociception caused by topical injection of capsaicin, with mean ID50 values of 6.2 and 16.0 mg/kg, respectively. Given orally (1 to 30 mg/kg) the ether fraction produced graded and pronounced inhibition of glutamate-induced hyperalgesia in mice with a mean ID50 value of 15.2 mg/kg. In contrast, the ether fraction failed to produce antinociception when assessed in the thermal model of pain, the tail flick and hot plate tests. The antinociception caused by the ether fraction, in contrast to that of morphine, was not reversed by naloxone when assessed in the formalin-induced licking. The ether fraction did not affect motor coordination or the core body temperature in mices. The triterpene Brein isolated from P. kleinii, given by i.p. route (10 to 100 mg/kg) produced dose-related inhibition of both phases of formalin induced-licking, with mean ID50s values of 15.3 and 20.6 for the early and the late phases, respectively. These data show that the active principle(s) present in the ether fraction from the resin of P. kleinii elicited pronounced antinociception when assessed by i.p. or p.o routes, against both inflammatory and neurogenic nociception. Such effects seem, at least in part, to be related to the presence of the triterpene Brein in the extract. The mechanisms responsible for the antinociceptive action are at this moment not completely understood, but the involvement of the opioid pathway seems unlikely.

Abstract
Along with three known drimanes, polygodial. 1-beta-(p-methoxycinnamoyl) polygodial and mukaadial, the sesquiterpene drimane named drimanial was isolated from the bark of Drimys winteri (Winteraceae). Its structure was elucidated based on spectroscopic evidence. Drimanial exhibited antinociceptive action against acetic acid induced pain, being about 3-fold less active than polygodial.

Abstract
This study investigated the vasorelaxant action of the sesquiterpene polygodial, isolated from the bark of Drymis winteri, on rat portal vein in vitro, contracted by various agonists. Polygodial (21-342 microM) preincubated 20 min before, produced graded antagonism of the contractile responses caused by bradykinin, endothelin-1, noradrenaline, the stable analogue of thromboxane A2 U46619, substance P, neurokinin B, and senktide (an NK3-selective agonist). Polygodial, at the same concentration, also produced graded inhibition of the contractile response induced by potassium chloride and by phorbol ester. At the median inhibitory concentration (IC50) level, polygodial was approximately 114- to 177-fold more active in inhibiting mediated contractions to senktide and phorbol ester. When assessed in the tonic contraction induced by endothelin-1 (0.5 nM) or by phorbol (3 microM), polygodial (0.1-100 microM) produced concentration-dependent relaxation, with maximal inhibition (E(max)) of 62 +/- 2% and 100%, respectively. Finally, polygodial (0.1-100 microM) inhibited the rhythmic spontaneous contractions of the rat portal vein (E(max) of 75 +/- 2%). Taken together, these results suggest that the vasorelaxant actions caused by polygodial in rat portal vein are, at least in part, associated with inhibition of calcium influx through voltage-sensitive channels and interaction with protein kinase C-dependent mechanisms. In addition, these data confirm and extend our previous suggestion that polygodial preferentially antagonizes tachykinin-mediated contraction, especially the NK3-mediated responses.

Abstract
Polygodial, a sesquiterpene isolated from the bark of Drymis winteri given systemically, intraplantarly, or by spinal or supraspinal sites, produced antinociception when assessed in both phases of the formalin test and against capsaicin-induced pain. Polygodial, even at high doses, had no antinociceptive or antihyperalgesic effect when assessed in hot-plate assay or in glutamate-induced hyperalgesia, nor did it significantly interfere with the motor coordination of animals when tested in the rota-rod test. The polygodial antinociception assessed in the formalin test was not affected by i.p. treatment of animals with cyprodime, yohimbine, phaclofen, bicuculine, or nitric oxide precursor or by intrathecal administration of potassium channel blockers such as apamin, charybdotoxin, glibenclamide, or tetraethylammonium. In contrast, polygodial antinociception was significantly attenuated by i.p. treatment of animals with naloxone, naltrindole, 2-(3, 4-dichlorophenyl)-n-methyl-n-[(1S)-1-(3-isothiocynatophenyl)-2-(1- pry rolidinyl)ethyl]acetamide, p-chlorophenylalanine, prazosin, or by i. c.v. treatment with pertussis toxin. In addition, polygodial antinociception was not cross-tolerant to morphine, nor was its effect affected by the adrenalectomy of animals. Together, these results show that polygodial produces pronounced systemic, spinal, and supraspinal antinociception in mice, mainly preventing the neurogenic pain produced by formalin and capsaicin. The mechanism by which polygodial produces antinociception seems likely to involve an interaction with the opioid system, mainly kappa and delta subtypes, depend on the activation of G(i/o) protein sensitive to pertussis toxin, alpha(1)-adrenoceptors, and the serotoninergic system. Collectively, these results suggest that polygodial itself or its derivatives may have potential therapeutic value for the development of new analgesic drugs.

Abstract
The sesquiterpene polygodial produces graded relaxation in rings of rabbit pulmonary artery or thoracic aorta and guinea-pig pulmonary artery with endothelium. In rings with rubbed endothelium its vasorelaxant action was largely reduced. The N(omega)-nitro-L-arginine (L-NOARG), N(G)-nitro-L-arginine methyl ester (L-NAME), 6-anilino-5,8-quinolinedione (LY 83583) and 1H-[1,2, 4]Oxadiazolo[4,3-a]quinoxalin-1-one (ODQ), inhibited the endothelium-dependent vasorelaxant action of polygodial. In contrast, N(omega)-nitro-D-arginine (D-NOARG), indomethacin, N(2)-[(4R)-4-hydroxy-1-(1methyl-1H-indol-3yl)carbonyl-L-prol yl]-N-met hyl-N-phenylmethyl-3-(2-naphthyl)-L-alaninamide (FK 888), (S)-N-methyl-N[4-(4-acetylamino-4-phenylpiperidino)-2-(3, 4-dichlorophenyl)butyl]benzamide (SR 48968), (8R,9S, 11S)-(-)-9-hydroxy-9-n-hexyloxy-carbonyl-8-methyl-2,3,9, 20-tetrahydro-8,11-epoxy-1H,8H,11H-2,7b,11a-triaqzadibenzo[a, g]cycloocta[c,d,e]-trinden-1-one (KT 5720), calcitocin gene-related peptide receptor antagonist (CGRP-(8-37), apamin, charybdotoxin and 4-aminopyridine had no effect on polygodial action. However, glibenclamide inhibited partially, but significantly, its relaxant responses. These results demonstrate that the vasorelaxation of polygodial is partly dependent on the release of nitric oxide (NO )or an NO-derived substance from the vascular endothelium through an activation of a guanylyl cyclase-dependent mechanism. Finally, results demonstrate that the polygodial vasorelaxant action is not related with the opening of potassium (K(+)) channels, release of prostacyclin, substance P, or with the activation of adenylyl cyclase-dependent mechanisms.

Abstract
In this review we discuss our recently results showing interleukin 5 (IL-5) involvement in eosinophil migration and in the maintenance of eosinophilia in blood, bone marrow, lung and peritoneal cavity, in a visceral larva migrans syndrome model using guinea-pigs infected with Toxocara canis. We also describe the sequential release of TNF-alpha and IL-8 during the course of infection. Finally we propose a biological role for IL-5, at least in our model, as a modulator of IL-8 release and secretion.
