Abstract
To evaluate the antibacterial, antibiofilm and antivirulence potential of the main diterpenes from Copaifera spp. oleoresins against multidrug-resistant (MDR) bacteria. Antimicrobial assays included determination of the Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), Minimum Inhibitory Concentration of Biofilm (MICB50), as well as synergistic and antivirulence assays for eight diterpenes against MDR. The tests revealed that two diterpenes (named 1 and 5) showed the best results, with MIC and MBC between 12.5 and 50 μg/mL against most MDR bacteria. These diterpenes exhibited promising MICB50 in concentration between 3.12-25 μg/mL but showed no synergistic antimicrobial activity. In the assessment of antivirulence activity, diterpenes 1 and 5 inhibited only one of the virulence factors evaluated (Dnase) produced by some strains of S. aureus at subinhibitory concentration (6.25 μg/mL). Results obtained indicated that diterpenes isolated from Copaifera oleoresin plays an important part in the search of new antibacterial and antibiofilm agents that can act against MDR bacteria.

Abstract
Gold nanoparticles (AuNPs) are highlighted due to their low toxicity, compatibility with the human body, high surface area to volume ratio, and surfaces that can be easily modified with ligands. Biosynthesis of AuNPs using plant extract is considered a simple, low-cost, and eco-friendly approach. Brazilian Red Propolis (BRP), a product of bees, exhibits anti-inflammatory, anti-tumor, antioxidant, and antimicrobial activities. Here, we described the biosynthesis of AuNPs using BRP extract (AuNPextract) and its fractions (AuNPhexane, AuNPdichloromethane, AuNPethyl acetate) and evaluated their structural properties and their potential against microorganisms and cancer cells. AuNPs showed a surface plasmon resonance (SPR) band at 535 nm. The sizes and morphologies were influenced by the BRP sample used in the reaction. FTIR and TGA revealed the involvement of bioactive compounds from BRP extract or its fractions in the synthesis and stabilization of AuNPs. AuNPdichloromethane and AuNPhexane exhibited antimicrobial activities against all strains tested, showing their efficacy as antimicrobial agents to treat infectious diseases. AuNPs showed dose-dependent cytotoxic activity both in T24 and PC-3 cells. AuNPdichloromethane and AuNPextract exhibited the highest in vitro cytotoxic effect. Also, the cytotoxicity of biogenic nanoparticles was induced by mechanisms associated with apoptosis. The results highlight a potential low-cost green method using Brazilian red propolis to synthesize AuNPs, which demonstrated significant biological properties.

Abstract
Solanum lycocarpum fruits contain two major glycoalkaloids (GAs), solamargine (SM) and solasonine (SS). These compounds are reported as cytotoxic. However, they have poor water solubility and low bioavailability. To overcome these disadvantages and getting an efficient formulation the current study aimed to develop, characterize, and test the effectiveness of a nanotechnology-based strategy using poly(D,L-lactide) (PLA) nanoparticles functionalized with folate as delivery system of glycoalkaloidic extract (AE) for bladder cancer therapy. The strategic of adding folic acid into nanoformulations can increase the selectivity of the compounds to the cancer cells reducing the side effects. Our results revealed the successful preparation of AE-loaded folate-targeted nanoparticles (NP-F-AE) with particle size around 177 nm, negative zeta potential, polydispersity index <0.20, and higher efficiency of encapsulation for both GAs present in the extract (>85 %). To investigate the cellular uptake, the fluorescent dye coumarin-6 was encapsulated into the nanoparticle (NP-F-C6). The cell studies showed high uptake of nanoparticles by breast (MDA-MB-231) and bladder (RT4) cancer cells, but not for normal keratinocytes cells (HaCaT) indicating the target uptake to cancer cells. The cytotoxicity of nanoparticles was evaluated on RT4 2D culture model showing 2.16-fold lower IC50 than the free AE. Furthermore, the IC50 increased on the RT4 spheroids compared to 2D model. The nanoparticles penetrated homogeneously into the urotheliumof porcine bladder. These results showed that folate-conjugated polymeric nanoparticles are potential carriers for targeted glycoalkaloidic extract delivery to bladder cancer cells.

Abstract
Two novel compounds bearing heterocyclic nitrogen, 2-pyridone alkaloid (1) and alloxazine derivative (2), along with the known pretenellin B (3), pyridovericin (4) and lumichrome (5) were isolated from a culture of the entomopathogenic fungal strain Beauveria bassiana. The chemical structures of 2-pyridone alkaloid and alloxazine derivative were established on the basis of the interpretation of spectroscopic data. The isolated compounds were evaluated in a panel of five cancer cell lines and pyridovericin exhibited cytotoxicity (IC50, μM) against cancer cell lines: HL-60 (25.9 ± 0.3), HCT8 (34.6 ± 3.6), MDA-MB435 (34.8 ± 3.8) and SF295 (31.1 ± 0.6). Considering that other pyridone compounds display good cytotoxic activity, it would be suggested to obtain new semi synthetic derivatives of pyridovericin, for the development of new cytotoxic chemical entities.

Abstract
A new aryltetralin lignan derivative, 1, was obtained by reacting dimethyl succinate and piperonal, furnishing the lactone 4-(3',4'-methylenedioxybenzyl)-4,5-dihydro-2(3H)-furanone, which was reacted once again with piperonal and LDA to give the dibenzylbutirolactone 7-hydroxyhinokinin. The cyclization of 7-hydroxyhinokinin into polygamain occurred in the presence of trifluoroacetic acid. The reduction of the furanic ring of polygamain was done by its reaction with DIBAL in THF, furnishing the diol functionalized lignin derivative 1 as single diastereomer. The enantiomeric fractions of 1 were obtained by preparative enantioselective HPLC. The absolute stereochemistry was assigned by electronic circular dichroism (ECD) and nuclear magnetic resonance (NMR) spectroscopy. An all-trans relative configuration was determined by NMR on the bases of ¹H coupling constants and nuclear Overhauser effect (n.O.e.) experiments. The absolute configuration at C1 was assigned on the basis of the ECD sign at 296 nm by comparison to the ECD spectra of structural analogues with defined stereochemistry. The assignment of the absolute configuration was confirmed by applying the exciton chirality method to the well-defined ECD couplets at 285 and 200 nm allied to the two electronic transitions L(b) and B(b) of the aromatic moieties, respectively. Rac-1 and its enantiomeric isomers were evaluated against important bacteria responsible for dental caries. The best results obtained for the (1R,2S,3S) isomer were against Streptococcus mutans (250 μM), Streptococcus salivarius (250 μM), Streptococcus sobrinus (280 μM) and Streptococcus mitis (280 μM). The (1S,2R,3R) isomer was active only against Streptococcus sanguinis (280 μM). The enantiomeric mixture was less active than the (1R,2S,3S) isomer.

Abstract
A possible immunomodulatory/anti-inflammatory effect of Baccharis dracunculifolia (Bd) and its major compound--caffeic acid (Ca)--on cytokines production (IL-1β, IL-6 and IL-10) by murine macrophages was investigated. Cells were incubated with Bd and Ca, and the inhibitory concentrations were tested before or after macrophages challenge with LPS. Bd and Ca stimulated IL-1β and inhibited IL-6 and IL-10 production. In LPS-challenge protocols, Bd prevented LPS action either before or after LPS challenge, whereas Ca prevented LPS effects only after LPS addition. Bd modulatory action on cytokines production may be at least in part mediated by Ca, since it has been shown to inhibit the transcription factor NF-κB. Further studies are still needed to evaluate Bd efficacy in inflammatory diseases, in order to explore its antiinflammatory activity in vivo.

Abstract
From cultures of thermophilic soil fungus Humicola grisea var thermoidea, a δ-lactam derivative (3-(2-(4-hydroxyphenyl)-2-oxoethyl)-5,6-dihydropyridin-2(1H)-one) that displayed anti-allergic activity was isolated, which was predicted by in silico computational chemistry approaches. The in vitro anti-allergic activity was investigated by β-hexosaminidase release assay in rat basophilic leukaemia RBL-2H3 cells. The δ-lactam derivative exhibited similar anti-allergic activity (IC(50) = 18.7 ± 6.7 µM) in comparison with ketotifen fumarate (IC(50) = 15.0 ± 1.3 µM) and stronger anti-allergic activity than azelastine (IC(50) = 32.0 µM). Also, the MTT cytotoxicity assay with RBL-2H3 cells showed that δ-lactam does not display cytotoxicity at concentrations lower than 50 µM. This study suggests that the δ-lactam derivative has the potential to be used as a lead compound in the development of anti-allergic drugs for clinical use in humans.

Abstract
(±)-Licarin A (1) was obtained by oxidative coupling, and its enantiomers, (-)-licarin A (2) and (+)-licarin A (3), were resolved by chiral HPLC. Schistosomicidal and trypanocidal activities of these compounds were evaluated in vitro against Schistosoma mansoni adult worms and trypomastigote forms of Trypanosoma cruzi. The racemic mixture (1) displayed significant schistosomicidal activity with an LC₅₀ value of 53.57 μM and moderate trypanocidal activity with an IC₅₀ value of 127.17 μM. On the other hand, the (-)-enantiomer (2), displaying a LC₅₀ value of 91.71 μM, was more active against S. mansoni than the (+)-enantiomer (3), which did not show activity. For the trypanocidal assay, enantiomer 2 showed more significant activity (IC₅₀ of 23.46 μM) than enantiomer 3, which showed an IC₅₀ value of 87.73 μM. Therefore, these results suggest that (±)-licarin A (1) and (-)-licarin A (2) are promising compounds that could be used for the development of schistosomicidal and trypanocidal agents.

Abstract
Baccharis dracunculifolia is the most important vegetal source of propolis in southeast Brazil, and researchers have been investigating its biological properties. Propolis is a complex resinous hive product collected by bees from several plants, showing a very complex chemical composition. It has been employed since ancient times due to its therapeutic properties, such as antimicrobial, anti-inflammatory, antioxidant, immunomodulatory and antitumour activities, among others. The goal of this work was to compare the cytotoxic action of B. dracunculifolia, propolis and two isolated compounds (caffeic and cinnamic acids) on human laryngeal epidermoid carcinoma (HEp-2) cells in vitro. These cells were incubated with different concentrations of each variable, and cell viability was assessed by the crystal violet method. Lower concentrations of B. dracunculifolia (extract and essential oil), propolis, as well as caffeic and cinnamic acids, showed no cytotoxic activity against HEp-2 cells. On the other hand, elevated concentrations (50 and 100 µg per 100 µL) exerted a cytotoxic action, and propolis showed a more efficient action than its vegetal source and isolated compounds. Further investigation is still needed in order to explore the potential of these variables as antitumour agents and to understand their mechanisms of action.

Abstract
Cymbopogon citratus has been widely recognised for its ethnobotanical and medicinal usefulness. Its insecticidal, antimicrobial and therapeutic properties have been reported, but little is known about its effect on the immune system. This work aimed to investigate the in vivo effect of a water extract of lemongrass on pro-inflammatory cytokine (IL-1beta and IL-6) production by macrophages of BALB/c mice. The action of lemongrass essential oil on cytokine production by macrophages was also analysed in vitro. The chemical composition of the extract and the oil was also investigated. Treatment of mice with water extract of lemongrass inhibited macrophages to produce IL-1beta but induced IL-6 production by these cells. Lemongrass essential oil inhibited the cytokine production in vitro. Linalool oxide and epoxy-linalool oxide were found to be the major components of lemongrass water extract, and neral and geranial were the major compounds of its essential oil. Taken together, these data suggest an anti-inflammatory action of this natural product.

Abstract
Biological properties of clove have been reported, but little is known about its effect on the immune system. This work was aimed to investigate the effect in vivo of a water-soluble part of hydroalcoholic extract of clove on pro-inflammatory cytokines (IL-1beta and IL-6) production by macrophages of BALB/c mice. The action of the essential oil of clove on the production of these cytokines macrophages was also investigated in vitro. The chemical compositions of the extract and of the oil were also investigated. Treatment of mice with water extract of clove was found to inhibit macrophages to produce both IL-1beta and IL-6. The essential oil of clove also inhibited the production of these cytokines in vitro. Eugenol was found to be the major component of the clove extract and essential oil, and probably is the causative agent of cytokine inhibition. Taken together, these data suggest an anti-inflammatory action of this spice.

Abstract
Aims: The aim of this work was to evaluate the antiviral activities of Baccharis dracunculifolia (extract and essential oil), propolis and some isolated compounds (caffeic and cinnamic acids) against poliovirus type 1 (PV1) replication in HEp‐2 cells. Method: Three different protocols (pre‐, simultaneous and post‐treatments) were used to verify the effect of addition time of the variables on PV1 replication by crystal violet method and relative viral RNA quantification by real‐time PCR for analysing in which step of virus replication the variables could interfere. Conclusions: Data revealed that the B. dracunculifolia showed the best antiviral activity percentage in the simultaneous treatment, as well as lower relative viral quantification by real‐time PCR. Variables might block partially the viral entry within cells, affect the steps of viral cycle replication into cells, or lead to RNA degradation before the virus entry into cells or after their release to the supernatant. Significance and Impact of the Study: Baccharis dracunculifolia is the most important botanical source of the south‐eastern Brazilian propolis, and its potential for the development of new phytotherapeutic medicines has been investigated. Propolis is commonly used for its antimicrobial and immunomodulatory activities. Nevertheless, B. dracunculifolia and propolis effects on PV1 have not been investigated yet.

The trypanocidal activity of racemic mixtures of cis- and trans-methylpluviatolides was evaluated in vitro against trypomastigote forms of two strains of Trypanosoma cruzi, and in the enzymatic assay of T. cruzi gGAPDH. The cytotoxicity of the compounds was assessed by the MTT method using LLC-MK2 cells. The effect of the compounds on peroxide and NO production were also investigated. The mixture of the trans stereoisomers displayed trypanocidal activity (IC50 approximately 89.3 microM). Therefore, it was separated by chiral HPLC, furnishing the (+) and (-)-enantiomers. Only the (-)-enantiomer was active against the parasite (IC50 approximately 18.7 microM). Despite being inactive, the (+)-enantiomer acted as an antagonistic competitor. Trans-methylpluviatolide displayed low toxicity for LLC-MK2 cells, with an IC50 of 6.53 mM. Furthermore, methylpluviatolide neither inhibited gGAPDH activity nor hindered peroxide and NO production at the evaluated concentrations.

Abstract
The activities of the crude ethanol extract from Piper cubeba seeds, (-)-cubebin and its semi-synthetic derivatives were evaluated against oral pathogens. The crude ethanol extract was more active against Streptococcus salivarius (MIC value of 80 microg/mL). (-)-Cubebin displayed MIC values ranging from 0.20 mm for Streptococcus mitis to 0.35 mm for Enterococcus faecalis. The natural product (-)-cubebin and its semi-synthetic derivative (-)-hinokinin displayed bacteriostatic activity at all evaluated concentrations, as well as fungicidal activity against Candida albicans at 0.28 mm. The O-benzyl cubebin derivative showed fungistatic and fungicidal effects against C. albicans at 0.28 mm and 0.35 mm, respectively. Also, the other dibenzylbutyrolactone derivatives [(-)-6,6'-dinitrohinokinin and (-)-O-(N,N-dimethylaminoethyl)-cubebin] displayed bacteriostatic and fungistatic effects at the evaluated concentrations. Moreover, the semi-synthetic derivative (-)-6,6'-dinitrohinokinin was the most active compound against all the evaluated microorganisms. Therefore, it may be suggested that the presence of the carbonyl group at C-9 plus the introduction of polar groups in the aromatic rings improve the antimicrobial activity of dibenzylbutyrolactone compounds.

Abstract
The effect of spray drying conditions on the chemical composition of Brazilian green propolis extract was investigated using a factorial design and high performance liquid chromatography. The raw and dried extract contents of caffeic acid, p-coumaric acid, drupanin, isosakuranetin, artepillin C, baccharin and 2,2-dimethyl-6-carboxyethenyl-2H-1-benzopyran were quantified using veratraldehyde (3,4-dimethoxybenzaldehyde) as internal standard. The baccharin content in spray-dried propolis was affected by the drying temperature with a 5% significance level, while the coumaric acid and drupanin contents were dependent on drying temperature at a 15% significance level. The other chemical markers, caffeic acid, isosakuranetin, artepillin C and 2,2-dimethyl-6-carboxyethenyl-2H-1-benzopyran, showed to be independent of drying conditions. However, all the chemical markers showed some loss on drying, which varied from 30 to 50%. The results showed that prenylated compounds are sensitive to drying, but their losses may be considerably reduced under low temperatures, around 40 degrees C. The antioxidant activity of the spray dried propolis was determined by the diphenylpicrylhydrazyl (DPPH) method and showed a quadratic dependency on the temperature; extract feed rate and the interaction between them. However, spray dried propolis extracts presented antioxidant activities similar to the original propolis tincturae.

Abstract
Austroplenckia populnea (Reiss) Lund is a Brazilian plant from "cerrado", which belongs to Celastraceae family, popularity know as "marmelinho-do campo, mangabeira-brava, mangabarana, vime and maria-mole". This plant is used in folk medicine to treat dysenteries and inflammatory disorders, such as rheumatism. Austroplenckia populnea bark hydroalcoholic crude extract, and its hexane, chloroform and ethyl acetate fractions, obtained by partition, as well as the isolated populnoic acid were investigated for their anti-inflammatory (carrageenan, dextran and histamine-induced rat paw oedema, histamine-induced increase in vascular permeability, and granulomatous tissue induction) and analgesic activities (writhing and hot plate tests). The ED(50) (oral) of the crude extract for the inhibition of carragenan-induced rat paw oedema assay was determined to be 200 mg/kg, which was also used in the assays with the extract and its fractions in all other experiments. Populnoic acid was administered in the dose of 50 mg/kg. Crude extract, hexane and chloroform fractions (200 mg/kg), and indomethacin (10 mg/kg) inhibited significantly (p<0.05) the formation of the carrageenan-induced rat paw oedema, measured in third hour of experiment (peak of oedema formation) by 43.2%, 37.3%, 31.1% and 59.3%, respectively. There was a significant reduction (p<0.05) in dextran-induced rat paw oedema in all groups, while in the assay using histamine as the oedematogenic agent, only the groups treated with populnoic acid (50 mg/kg) and cyproheptadine (10 mg/kg) displayed significant reduction (p<0.05). The populnoic acid and cyproheptadine reduced the peak of oedema formation (1st hour) by 41.3% and 34.7%, respectively. Only for the groups treated with populnoic acid (50 mg/kg) and cyproheptadine (10 mg/kg) it was observed a significant (p<0.05) reduction in histamine-induced increase in vascular permeability (44.8% and 80.3%, respectively). Granulomatous tissue formation was significantly inhibited (p<0.05) by both hexane fraction (46.0%) and dexamethasone (66.2%). In the analgesic assays, the crude extract and its hexane and chloroform fractions, as well as indomethacin diminished significantly the number of writhings (p<0.05) by 69.6%, 47.2%, 44.8% and 62.8%, respectively. On the other hand, none assayed sample displayed significant result in the hot plate test. Based on the obtained results it is suggested that extracts of Austroplenckia populnea bark and populnoic acid display anti-inflammatory activity, supporting its folkloric use to treat inflammatory disorders.

Abstract
The anti-inflammatory and antinociceptive effects of the crude hydroalcoholic extract (PE) of Pfaffia glomerata roots was assessed in the carrageenan-induced rat paw edema at the doses of 100, 200 and 300 mg/kg, using different animal models. An anti-inflammatory dose effect response correlation of r=0.997 and Y=11.67x+0.02 was found. At the same doses, the extract-inhibited acetic acid-induced writhing in mice, but no dose response correlation was found. Oral administration of 100 mg/kg of PE and 0.5 mg/kg of dexamethazone inhibited by 29 and 61%, the granulomatous tissue formation (p>0.05), respectively. These results indicate the potential of this plant extract to treat chronic inflammation. At the assayed doses no significant activity was found in the hot plate test, as well as in the cell migration-induced by carrageenan.

Abstract
Three different concentrations (1, 10 and 50 microg/ml) of lyophilized hydroalcoholic crude extract of Pfaffia glomerata roots were assayed in vitro against strains of Trypanosoma cruzi (Y) and Leishmania braziliensis. It was observed that P. glomerata hydroalcoholic extract was relatively active within the tested concentrations for L. (V) braziliensis, but inactive against T. cruzi. Despite the fact that both protozoans belong to the Trypanosomatidae family, we suggest that the difference observed for activity should be related to the biological differences between the two parasite species.

Abstract
The anti-inflammatory and antinociceptive effects of the acetylated (2), methylated (3) and aminated (4) derivatives of cubebin (1), obtained by its reaction with acetic anhydride, methyl iodide and dimethylethylamine chloride, respectively, were investigated, using different animal models. The compound (2) was the most effective anti-inflammatory one in the carrageenin-induced paw edema in rats and was the only one which showed dose-response correlation for this assay with r = 0.993 and Y = 64.58x + 0.22. Besides, compounds (2) and (4) were more effective than cubebin in inhibiting acetic acid-induced writhing in mice, producing dose-response correlation with doses of 10, 20 and 30 mg/kg, respectively. Regarding the hot plate and the cell migration tests in rats, none of the four tested compounds showed activity. Overall, the results showed that the acetylation and amination of cubebin were efficient in enhancing its analgesic activity, as well as its anti-inflammatory activity.

Abstract
The activity of a crude ethanol extract of green propolis and its fractions obtained by partition with hexane, chloroform and n-butanol was assessed on luminol- and lucigenin- enhanced chemiluminescence (CL) produced by rabbit neutrophils (PMNs) stimulated with particles of serum-opsonized zymosan (OZ). The total production of reactive oxygen species (ROS) by PMNs was measured by the luminol-enhanced CL (LumCL) assay and the production of the superoxide anion (O2*-) by the lucigenin-enhanced CL (LucCL) assay. All evaluated propolis samples had inhibitory effect on the LumCL and LucCL, which was concentration dependent. The n-butanol and chloroform fractions displayed the highest inhibitory effect on the LumCL produced by PMNs stimulated with OZ, in comparison with both the ethanol extract and the hexane fraction. Besides, the hexane fraction was the one which presented the highest effect for the LucCL assay. Some isolated compounds from both n-butanol and chloroform fractions were also assessed, including kaempferide, isosakuranetin, aromadendrine-4'-methyl-ether and 3-prenyl-p-coumaric acid. Kaempferide presented the highest inhibitory effect on the LumCL in comparison with the other compounds. Moreover, under the conditions assessed, the studied green propolis samples and isolated compounds were not toxic to the rabbit PMNs.

Abstract
The anti-inflammatory and antinociceptive effects of the benzylated cubebin derivative, obtained by reaction of (-)-cubebin with benzyl bromide, were investigated using different animal models. The (-)-o-benzyl cubebin showed a low anti-inflammatory effect (16.2%) in relation to cubebin (57%) and indomethacin (77%) in the carrageenin-induced paw edema in rats, but on the other hand it was more effective (80%) than (-)-cubebin (41%) in inhibiting acetic acid-induced writhing in mice, producing dose-response correlation with doses of 10, 20 and 40 mg/kg, respectively. Moreover, this derivative compound did not show activity in both the hot plate and the cell migration test in rats. Overall, the results showed that the benzylation of cubebin were efficient in enhancing only its analgesic activity.

Abstract
Cubebin, a dibenzylbutyrolactone lignan isolated from the crude hexane extract of the leaves of Zanthoxyllum naranjillo, showed a significant anti-inflammatory activity by using the paw edema induced by carrageenin in rats, but did not provide a significant reduction in the cell migration for the acute carrageenin-induced inflammatory reaction in the peritoneal cavity of rats. Neither was it effective in reducing the edema induced by dextran nor the edema induced by histamine. It partially reduced the edema induced by serotonin. Moreover, it significantly reduced the edema induced by prostaglandin PGE2 and the number of writhings induced by both acetic acid and PGI2 in mice. Therefore, it may be suggested that the mechanism of action of cubebin is similar to that observed for most of the non-steroidal drugs.

Abstract
Seven lignans isolated from the hexane extract of the leaves of Zanthoxyllum naranjillo (Rutaceae) were tested in both in vitro and in vivo assays against two strains of Trypanosoma cruzi (Bolivia and Y). Of the seven assayed lignans, three were inactive [(+)-sesamin, (+)-piperitol-4'-O-gamma, gamma-dimethylallyl ether and (-)-3,4-dimethoxy-3',4'-demethylenedioxycubebin] and three were partially active in the in vitro assays [(-)-hibalactone, (-)-kaerophylin and (-)-cubebin]. Healthy animals developed the disease after injection of the tested infected blood samples containing these three compounds. One compound [(-)-methylpluviatolide] was highly effective in the in vitro assay and healthy animals injected with the tested samples did not develop the disease. Moreover, only (-)-methylpluviatolide was highly active against the bloodstream forms of both strains of T. cruzi for the in vivo assay. However, it was not active against the tissue forms of the parasite.

Abstract
The vegetal species Pterodon emarginatus Vog. (Leguminosae/Papilonaceae), popularly known in Brazil as 'sucupira branca', is widely used by domestic medicine as an anti-inflammatory. From these observations, the hexanic crude extract (HCE) of the fruits was obtained and submitted for assessment of its anti-inflammatory activity. For this purpose, the following tests were used: (1) Determination of ED50 and LD50; (2) Paw edema induced by carrageenin, dextran, histamine and nystatin; (3) Peritonitis caused by carrageenin and (4) Granuloma test. The ED50 (oral) in the edema induced by carrageenin was 500 mg/kg, and LD50 (oral) was 4.02 g/kg. In the edema caused by nystatin, there was a significant inhibition by 45% (P < 0.05 student's t-test) at the 6th hour following the treatment. In the granuloma test performed in animals treated with HCE, there was an inhibition of the granulomatous tissue formation by 22%. The migration of neutrophils towards the peritoneal cavity was inhibited in HCE treated animals by 43% (P < 0.05). However, in the edema caused by dextran and histamine, there was no significant response in HCE treated animals.

Abstract
The phytochemical study using Virola michelli Heckel (Myristicaceae) leaves allowed the isolation of a flavone named titonine (7,4'-dimethoxy-3'-hydroxyflavone). Titonine was further submitted to methylation and acetylation reactions yielding a 7,3',4'-trimethoxyflavone and a 7,3'-dimethoxy-4'-acetylflavone, respectively. These compounds were evaluated for both anti-inflammatory and analgesic activity. The anti-inflammatory activity was evaluated in rats using the paw edema test with carrageenin, while the analgesic activity was determined in mouse using the writhing test method. The different animal groups were treated with three compounds (10 mg/kg -i.p.) thirty min prior to stimuli application. The inhibition levels obtained for each compound were 22, 41 and 68%, respectively. Using the writhing test, oral doses of 5, 10 and 15 mg/kg of natural flavone reduced the acetic acid-induced contortions in a dose-dependent manner.

Abstract
The lignan podophyllotoxin, occurring in Podophyllum emodi Wall, ex Royale and Podophyllum peltatum. L., is the starting compound for the semi-synthesis of the anticancer drugs etoposide and teniposide. In this study, we evaluate development of an in vitro propagation protocol to rapidly produce high yielding Podophyllum peltatum plants. Rhizome tips were inoculated on MS medium supplied with 4.4 microM N(6)-benzyladenine and 0.025% (w/v) activated charcoal. These explants formed terminal buds, similar to the ones found in nature. These buds were sources of in vitro bud cultures. These bud cultures were classified as: apical, axillary, and adventitious and the effects of various N(6)-benzyladenine concentrations on the three types of bud cultures were evaluated through bud, leaf, and root inductions. Cultures of axillary and adventitious buds were more proliferous for bud induction. Podophyllotoxin contents of in vitro rooted bud and plantlet cultures were similar to the content found in the wild. Plantlets and buds were acclimatized under controlled environment conditions.

Galanthamine, an alkaloid present in the Amaryllidaceae is currently undergoing clinical trials for the treatment of Alzheimer's. Common daffodils, Narcissus spp., contain galanthamine and other alkaloids. Four commercial Narcissus cultivars were evaluated as potential sources of galanthamine. Planting depths, planting densities, bulb size or flower bud removal did not affect galanthamine content.

Abstract
Bulbs of Narcissus were dissected into outer and inner scales, leaves, basal plate, flower, and bulbils to determine the distribution of alkaloids among different tissues. Quantitation of galanthamine as well as the other alkaloids was accomplished by capillary gas chromatography.

Abstract
The anti-inflammatory and antinociceptive effects of trans-dehydrocrotonin, isolated from the bark of Croton cajucara (Euphorbiaceae), were investigated using several animal models. The trans-dehydrocrotonin produced a significant inhibition of carrageenin-induced paw edema and cotton pellet granuloma in rats. It also inhibited the writhings in mice induced by acetic acid, but did not show a significant effect in the hot-plate test in mice. The LD50 of t-DCTN was 555.0 mg/kg (p.o.) for mice.

Abstract
The crude aqueous extract of the fruits of Caesalpinia ferrea Mart. (Leguminosae) has been investigated for possible anti-inflammatory and analgesic properties. The carrageenan induced rat hind paw edema was significantly inhibited (P < 0.05) by oral administration of 300 mg/kg of this extract. A centrally mediated analgesic effect was not observed, however, there was a dose dependent reduction in the number of total writhes induced by acetic acid.
