Abstract
Cryptococcosis, caused by Cryptococcus spp., is an invasive fungal infection of the central nervous system, associated with high mortality, affecting mainly immunocompromised patients. Due to the development of resistance to the current therapy, there is an urgent need for less toxic and more effective antifungal agents. In this study, we describe the antifungal activity against Cryptococcus spp. of an aqueous seed extract from Allamanda polyantha (ASEAP) and two iridoids, plumieride and plumieridine, isolated from this extract with an antifungal activity. The capsule formation and the morphological alterations were evaluated using fluorescent microscopy. The cytotoxic activity was also investigated. The minimal inhibitory concentration (MIC) values of ASEAP for Cryptococcus gattii were 70 and 36 µg/ml (for the R265 and R272 strains, respectively) and 563 µg/ml for Cryptococcus neoformans H99. ASEAP inhibited C. neoformans H99 capsule formation, an important virulence factor, and decreased the cell body size for both the C. gattii strains. H99 cells also presented morphological alterations, with defects in bud detachment and nuclear fragmentation. Plumieride and plumieridine presented higher MIC values than ASEAP, indicating that other compounds might contribute to antifungal activity and/or that combination of the compounds results in a higher antifungal activity.

Abstract
Soybean acid hydrolyzed extracts are raw-materials widely used for manufacturing of pharmaceuticals and cosmetics products due to their high content of isoflavone aglycones. In the present study, the main sugar degradation products 5-hydroxymethyl-2-furfural (HMF) and 5-ethoxymethyl-2-furfural (EMF) were quantitatively determined after acid hydrolysis of extracts from different soybean cultivars by a validated liquid chromatography method. The furanic compounds determined in samples cover the range of 0.16-0.21mg/mL and 0.22-0.33mg/mL for HMF and EMF, respectively. Complementarily, due to the scarce literature regarding the EMF toxicology, this study also assessed the EMF mutagenicity by the Salmonella/microsome test and genotoxicity by the comet assay. The results revealed that EMF did not show mutagenicity at the range of 50-5000μg/plate in S. typhimurium strains TA98, TA97a, TA100, TA102 and TA1535, but induced DNA damage in HepG2 cells at non-cytotoxic doses of 0.1-1.3mg/mL, mainly by oxidative stress mechanisms. Based on literature of HMF genotoxicity, and considering the EMF genotoxicity results herein shown, purification procedures to remove these impurities from extracts are recommended during healthcare products development to ensure the security of the products.

Abstract
Imidazoles and benzimidazoles are privileged heterocyclic bioactive compounds used with success in the clinical practice of innumerous diseases. Although there are many advancements in cancer therapy, microtubules remain as one of the few macromolecular targets validated for planning active anti-cancer compounds, and the design of drugs that modulate microtubule dynamics in unknown sites of tubulin is one of the goals of the medicinal chemistry. The discussion of the role of new and commercially available imidazole and benzimidazole derivatives as tubulin modulators is scattered throughout scientific literature, and indicates that these compounds have a tubulin modulation mechanism different from that of tubulin modulators clinically available, such as paclitaxel, docetaxel, vincristine and vinblastine. In fact, recent literature indicates that these derivatives inhibit microtubule formation binding to the colchicine site, present good pharmacokinetic properties and are capable of overcoming multidrug resistance in many cell lines. The understanding of the mechanisms involved in the imidazoles/benzimidazoles modulation of microtubule dynamics is very important to develop new strategies to overcome the resistance to anti-cancer drugs and to discover new biomarkers and targets for cancer chemotherapy.

Abstract
Three dimeric acylphloroglucinols, austrobrasilol A, austrobrasilol B and isoaustrobrasilol B were isolated from the flowers of Hypericum austrobrasiliense (Hypericaceae, section Trigynobrathys). Their structures were elucidated using mass spectrometry and NMR experiments (1D and 2D), and by comparison with previously reported data for other dimeric acylphloroglucinols isolated from Hypericum and Elaphoglossum genera. The three compounds were orally administered in mice at equimolar doses to uliginosin B (15mg/kg, p.o.) displaying antinociceptive activity in the hot-plate test. The compounds did not induce motor impairment in the rotarod apparatus.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Wounds are normally resolved in a few days, but chronic wounds represent a major burden because of economic and social factors. Thereby, the search for new agents is ongoing and natural products become a great target. Also, Brazil as a consumer of herbal medicines with rich social diversity is promising for ethnopharmacological studies. AIMS OF THE STUDY The study aims to find the plants popularly used for wound healing purposes in Rio Grande do Sul state, and test the traditional knowledge through an in vitro screening. MATERIALS AND METHODS Ethnobotanical studies from state of Rio Grande do Sul were analyzed to find the most used plants to treat wounds. The selected species were collected, identified and ethanolic and aqueous extracts were prepared. After, proliferative capacity was accessed by MTT assay in a keratinocyte cell line (HaCaT). RESULTS The survey comprehended almost all state regions and led to 117 plant species from 85 genera, from which 14 were selected for in vitro testing. Aqueous extracts from Achyrocline satureioides DC Lam., Matricaria recutita L., Melia azedarach L. and Mirabilis jalapa L. demonstrated the ability to stimulate keratinocyte growth up to 120% in concentrations of 25 µg/mL and 50 µg/mL. The ethanolic extract of A. satureioides was able to stimulate keratinocyte and fibroblast proliferation on the lower concentration tested, 1 µg/mL, being the most promising species. CONCLUSIONS The traditional knowledge collected from the ethnobotanical studies was accessed by in vitro investigation and extracts from Achyrocline satureioides, Matricaria recutita, Melia azedarach and Mirabilis jalapa can influence positively cell proliferation.

Abstract
There is a growing interest in the pharmaceutical field concerning isoflavones topical delivery systems, especially with regard to their skin care properties and antiherpetic activity. In this context, the present work describes an ultra-fast liquid chromatography method (UFLC) for determining daidzein, glycitein, and genistein in different matrices during the development of topical systems containing isoflavone aglycones (IA) obtained from soybeans. The method showed to be specific, precise, accurate, and linear (0.1 to 5 µg mL(-1)) for IA determination in soybean acid extract, IA-rich fraction obtained after the purification process, IA loaded-nanoemulsions, and topical hydrogel, as well as for permeation/retention assays in porcine skin and porcine esophageal mucosa. The matrix effect was determined for all complex matrices, demonstrating low effect during the analysis. The stability indicating UFLC method was verified by submitting IA to acidic, alkaline, oxidative, and thermal stress conditions, and no interference of degradation products was detected during analysis. Mass spectrometry was performed to show the main compounds produced after acid hydrolysis of soybeans, as well as suggest the main degradation products formed after stress conditions. Besides the IA, hydroxymethylfurfural and ethoxymethylfurfural were produced and identified after acid hydrolysis of the soybean extract and well separated by the UFLC method. The method's robustness was confirmed using the Plackett-Burman experimental design. Therefore, the new method affords fast IA analysis during routine processes, extract purification, products development, and bioanalytical assays.

Abstract
Diene valepotriates obtained from Valeriana glechomifolia present antidepressant-like activity, mediated by dopaminergic and noradrenergic neurotransmissions. Also, previous studies have shown inhibitory activity of diene valepotriates towards Na(+)/K(+)-ATPase from the rat brain in vitro. Nevertheless, in vivo studies regarding the action of diene valepotriates on this enzyme are still lacking. Considering that Na(+)/K(+)-ATPase cerebral activity is involved in depressive disorders, the aim of this study was to investigate the effects of acute (5 mg/kg, p. o.) and repeated (5 mg/kg, p. o., once a day for three days) diene valepotriate administration on Na(+)/K(+)-ATPase activity in the cortex and hippocampus of mice submitted or not submitted to the forced swimming test. In addition, the protein expression of Na(+)/K(+)-ATPase α1, α2, and α3 isoforms in the cortex of mice repeatedly treated with diene valepotriates (and submitted or not submitted to the forced swimming test) was investigated. Diene valepotriates significantly decreased mice immobility time in the forced swimming test when compared to the control group. Only the animals repeatedly treated with diene valepotriates presented increased Na(+)/K(+)-ATPase activity in the cerebral cortex, and the exposure to the forced swimming test counteracted the effects of the diene valepotriates. No alterations in the hippocampal Na(+)/K(+)-ATPase activity were observed. Repeated diene valepotriate administration increased the cortical content of the α2 isoform, but the α3 isoform protein expression was augmented only in mice repeatedly treated with diene valepotriates and forced to swim. Mice treated with the vehicle and submitted to the forced swimming test also presented an increase in the content of the α2 isoform, but no alterations in Na(+)/K(+)-ATPase activity. These results suggest that cortical Na(+)/K(+)-ATPase may represent a molecular target of the diene valepotriates in vivo and long-term regulatory mechanisms are involved in this effect. Also, the forced swimming test per se influences the protein expression of Na(+)/K(+)-ATPase isoforms and counteracts the effects of the diene valepotriates on cortical Na(+)/K(+)-ATPase.

Abstract
Uliginosin B is a natural phloroglucinol derivative, obtained from Hypericum species native to South America. Previous studies have shown that uliginosin B presents antidepressant-like and antinociceptive effects. Although its mechanism of action is still not completely elucidated, it is known that it involves the activation of monoaminergic neurotransmission. The aim of the current study was to further investigate the antinociceptive mechanism of action of uliginosin B by combining it with different drugs used for treating pain in clinical practice. The intraperitoneal administration of uliginosin B, morphine, amitriptyline and clonidine, alone or in mixture, produced a dose-dependent antinociceptive effect in the hot-plate assay in mice. The effect of the mixtures of drugs was studied using an adapted isobologram analysis at the effect level of 50% of the maximal effect observed. The analysis showed that the interactions between uliginosin B and morphine was synergistic, while the interactions between uliginosin B and amitriptyline or clonidine were additive. These findings point to uliginosin B as a potential adjuvant for pain pharmacotherapy, especially for opioid analgesia.

Abstract
The antidepressant-like effect of a supercritical CO2 (SCCO2) Valeriana glechomifolia extract enriched in valepotriates was investigated in a mice tail suspension test (TST) and forced swimming test (FST). The SCCO2 extract decreased mice immobility in the FST (0.5-20 mg/kg p.o.) and elicited a biphasic dose-response relationship in the TST (1-20 mg/kg p.o.) with no alterations in locomotor activity and motor coordination (assessed in the open-field and rota-rod tests, respectively). The anti-immobility effect of the SCCO2 extract (5 mg/kg, p.o.) was prevented by mice pre-treatment with yohimbine (1 mg/kg, i.p., an α2 adrenoceptor antagonist), SCH 23390 (15 μg/kg, s.c., D1 dopamine receptor antagonist) and sulpiride (50 mg/kg, i.p., D2 dopamine receptor antagonist). However, mice pre-treatments with prazosin (1 mg/kg, i.p., α1 adrenoceptor antagonist) and p-chlorophenilalanine methyl ester (4×100 mg/kg/day, i.p., a serotonin synthesis inhibitor) were not able to block the anti-immobility effect of the SCCO2 extract. Administration (p.o.) of the SCCO2 extract (0.25 mg/kg) and imipramine (10 mg/kg), desipramine (5 mg/kg) and bupropion (3 mg/kg) at sub-effective doses significantly reduced mice immobility time in the FST. These data provide the first evidence of the antidepressant-like activity of V. glechomifolia valepotriates, which is due to an interaction with dopaminergic and noradrenergic neurotransmission.

Abstract
In this study we have demonstrated that cyclohexane extract of Hypericum polyanthemum (POL) and its main phloroglucinol derivative uliginosin B (ULI) present antidepressant-like activity in rodent forced swimming test (FST). The involvement of monoaminergic neurotransmission on the antidepressant-like activity of ULI was evaluated in vivo and in vitro. POL 90 mg/kg (p.o.) and ULI 10 mg/kg (p.o.) reduced the immobility time in the mice FST without altering locomotion activity in the open-field test. The combination of sub-effective doses of POL (45 mg/kg, p.o.) and ULI (5 mg/kg, p.o.) with sub-effective doses of imipramine (10 mg/kg, p.o.), bupropion (3 mg/kg, p.o.) and fluoxetine (15 mg/kg, p.o.) induced a significant reduction on immobility time in FST. The pretreatment with SCH 23390 (15 μg/kg, s.c., dopamine D1 receptor antagonist), sulpiride (50 mg/kg, i.p., dopamine D2 receptor antagonist), prazosin (1mg/kg, i.p., α1-adrenoceptor antagonist), yohimbine (1mg/kg, i.p., α2-adrenoceptor antagonist) and pCPA (100 mg/kg/day, i.p., p-chlorophenilalanine methyl ester, inhibitor of serotonin synthesis, for four consecutive days) before ULI administration (10 mg/kg, p.o.) significantly prevented the anti-immobility effect in FST. ULI was able to inhibit synaptosomal uptake of dopamine (IC50 = 90 ± 38 nM), serotonin (IC50 = 252 ± 13 nM) and noradrenaline (280 ± 48 nM), but it did not bind to any of the monoamine transporters. These data firstly demonstrated the antidepressant-like effect of POL and ULI, which depends on the activation of the monoaminergic neurotransmission in a different manner from the most antidepressants.

Abstract
Hesperozygis ringens (Benth.) Epling (Lamiaceae) is a strongly aromatic plant employed popularly for its antiparasitic properties. The leaves afforded 4% of essential oil constituted mainly by pulegone (86%). Laboratory tests were carried out to determine the toxicity of the essential oil species on engorged females and larvae of the cattle tick Riphicephalus (Boophilus) microplus using the adult immersion test (AIT) and the larval immersion test (LIT). It was observed that the essential oil at the concentration of 50 microL/mL and 25 microL/mL inhibited the egg laying significatively in relation to the controls and the eggs from these treated females were affected by the oil; the hatching was inhibited in 95% and 30%, respectively. In the LIT it was verified that the LC(99.9), LC(50) and LC(1) was 0.541 microL/mL, 0.260 microL/mL and 0.015 microL/mL, respectively. Pulegone, isolated from the oil, showed similar effect on the females and on the larvae, indicating that it is responsible for the oil activity.

Abstract
The antiproliferative activity of three benzopyrans isolated from the chloroform extract of the aerial parts of Hypericum polyanthemum was analysed in order to determine their effect on the growth and cell cycle in the U-373 MG glioblastoma cell line. Compound 1 was less cytotoxic than compounds 2 and 3. A synergistic effect was noticed when the three benzopyrans were used simultaneously. The cytotoxicity noted could be related to an arrest in G2/M phase, leading to apoptosis in the U-373 MG glioblastoma cell line.

Abstract
In the present study we used the micronuclei test and the comet assay in mice to investigate the genotoxic and mutagenic effects of three benzopyrans--6-isobutyryl-5,7-dimethoxy-2,2-dimethyl-benzopyran (HP1); 7-hydroxy-6-isobutyryl-5-methoxy-2,2-dimethyl-benzopyran (HP2); and 5-hydroxy-6-isobutyryl-7-methoxy-2,2-dimethyl-benzopyran (HP3)--isolated from Hypericum polyanthemum. No significant difference in polychromatic erythrocyte (PCE) percentage between the vehicle group and groups treated with HP1, HP2, or HP3 was detected, indicating no toxicity to the bone marrow of the animals. Only HP1 increased the frequency of micronucleated cells (MNPCEs) in bone marrow sampled after 24 h in comparison with the vehicle group, suggesting a weak mutagenic effect. The damage index and damage frequency did not show a significant increase after treatment with HP1, HP2, or HP3 in comparison with the vehicle group. The antitumor activity previously reported in vitro for these benzopyrans, the lack of acute toxicity, the MN induction only for HP1, and the relatively low DNA damage make all compounds good candidates for in vivo studies on antitumor action.

Abstract
In this work, previously published and unpublished results on biological activity of Hypericum caprifoliatum, a native species to South Brazil, are presented. Lipophilic extracts obtained from this species showed an antidepressant-like activity in mice and rat forced swimming test. Results from in vivo experiments suggest an effect on the dopaminergic transmission. Besides that, in vitro experiments demonstrated that the extract and its main component (a phloroglucinol derivative) inhibit monoamine uptake in a concentration-dependent manner, more potently to dopamine, but this effect is not related to direct binding at the uptake sites. It was also observed that a 3-day treatment with lipophilic extract prevents stress-induced corticosterone rise in mice frontal cortex but not in plasma. The lipophilic and methanolic H. caprifoliatum extracts also demonstrated antinociceptive effect, which seems to be indirectly mediated by the opioid system. These results indicate that H. caprifoliatum presents a promising antidepressant-like effect in rodents which seems to be related to a mechanism different from that of other classes of antidepressants.

Abstract
In the present study we have investigated the in vitro antitumor effects of three benzopyrans, 6-isobutyryl-5,7-dimethoxy-2,2-dimethylbenzopyran (1), 7-hydroxy-6-isobutyryl-5-methoxy-2,2-dimethylbenzopyran (2) and 5-hydroxy-6-isobutyryl-7-methoxy-2,2-dimethylbenzopyran (3) isolated from Hypericum polyanthemum. The three compounds tested demonstrated potent growth inhibitory activity at 40 microg/ml (<25% control growth) in the NCI-H460, HT-29 and U-373MG human cell lines. Determination of cell cycle distribution demonstrated that the antiproliferative effect of the three benzopyrans could be associated to alterations in the cell cycle phase distribution. Treatment with the IC50 of the three compounds induced an arrested in S phase. Only in cells treated with compound 3 did the percentage of sub-G1 population increase up to 9%, suggesting that this compound induced more cell death than the others. Consistent with sub-G1 analysis, appreciable oligonucleosomal DNA fragmentation was only observed in the NCI-H460 cell line treated with compound 3. From these results it can be suggested that despite no differences among the cytotoxicity of the three compounds, it was observed that the mechanism of their antiproliferative effects appears to be different.

Abstract
Recently the crude methanol extracts of six Hypericum species were analysed against a panel of microorganisms and it was found that H. caprifoliatum Cham. & Schlecht., H. myrianthum Cham. & Schlecht. and H. polyanthemum Klotzsch ex Reichardt were the most active. This paper reports the activity of the hexane, chloroform and methanol fractions of these plants as well as the activity of some isolated compounds against Staphylococcus aureus determined by bioautographic procedures.
