Abstract
Diseases such as cancer, neurological pathologies and chronic pain represent currently unmet needs. The existing pharmacotherapeutic options available for treating these conditions are limited by lack of efficiency and/or side effects. Transient receptor potential vanilloid 1 ion channel emerged as an attractive therapeutic target for developing new analgesic, anti-cancer and antiepileptic agents. Furthermore, various natural ingredients were shown to have affinity for this receptor. The aim of this narrative review was to summarize the diverse natural scaffolds of TRPV1 modulators based on their agonistic/antagonistic properties and to analyze the structure-activity relationships between the ligands and molecular targets based on the results of the existing molecular docking, mutagenesis and in vitro studies. We present here an exhaustive collection of TRPV1 modulators grouped by relevant chemical features: vanilloids, guaiacols, phenols, alkylbenzenes, monoterpenes, sesquiterpenoids, alkaloids, etc. The information herein is useful for understanding the key structural elements mediating the interaction with TRPV1 and how their structural variation impacts the interaction between the ligand and receptor. We hope this data will contribute to the design of novel effective and safe TRPV1 modulators, to help overcome the lack of effective therapeutic agents against pathologies with high morbidity and mortality.

Abstract
Drimys winteri J.R.Forst. & G.Forst, a South American evergreen shrub that is used by the Mapuche people for treatment of several painful conditions, contains polygodial, a lipophilic drimane-type sesquiterpene dialdehyde with known activity at transient receptor potential channel family members including TRPA1 and TRPV1. We sought to assess the activity of polygodial at NaV1.7 and NaV1.8, two key isoforms of the voltage-gated sodium channel family involved in nociception. Polygodial was isolated from D. winteri by thin-layer chromatography and analysed structurally by 1 D and 2 D nuclear magnetic resonance (NMR) spectroscopy. Activity at heterologously expressed NaV1.7 and NaV1.8 was assessed using automated whole-cell patch-clamp electrophysiology. Here, we show that polygodial inhibits members of the voltage-gated sodium channel family, specifically NaV1.7 and NaV1.8, without changing the voltage-dependence of activation or inactivation. Activity of polygodial at voltage-gated sodium channels may contribute to the previously reported antinociceptive properties.

Nitric oxide-mediated defensive and antinociceptive responses organised at the anterior hypothalamus of mice are modulated by glutamatergic inputs from area 24b of the cingulate cortex.

Abstract
BACKGROUND Previous studies suggested that Cg1 area of the cingulate cortex of rats controls glutamate-mediated fear-induced defensive behaviour and antinociception organised at the posterior hypothalamus. In turn, microinjection of the nitric oxide donor SIN-1 into the anterior hypothalamus of mice produced defensive behaviours and fear-induced antinociception. However, it remains unknown whether Cg1 also modulates the latter mechanisms in mice. AIMS The present study examined the influence of Cg1 on SIN1-evoked fear-induced defensive behaviour and antinociception organised at the anterior hypothalamus of mice. METHODS The fear-like behavioural and antinociceptive responses to the microinjection of SIN-1 (300 nmol) into the anterior hypothalamus were evaluated after the microinjection of either N-methyl-D-aspartic acid receptor agonist (0.1, 1 and 10 nmol) or physiological saline into the cingulate cortex of C57BL/6 male mice. In addition, neurotracing and immunohistochemistry were used to characterise Cg1-anterior hypothalamus glutamatergic pathways. RESULTS The data showed that activation of Cg1 N-methyl-D-aspartic acid receptors increased escape while reducing freezing and antinociceptive responses to SIN-1 microinjections into the anterior hypothalamus. Anterograde neural tract tracer co-localised with VGLUT2-labelled fibres suggests these responses are mediated by glutamatergic synapses at the anterior hypothalamus. CONCLUSIONS In contrast with previous studies showing that Cg1 facilitates both escape and antinociception to chemical stimulation of the posterior hypothalamus in rats, the present data suggest that Cg1 facilitates escape while inhibiting defensive antinociception produced by the microinjection of SIN-1 in the anterior hypothalamus of mice. Accordingly, Cg1 may have opposite effects on antinociceptive responses organised in the anterior and posterior hypothalamus of mice and rats, respectively.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Hyptis comprehends almost 400 species widespread in tropical and temperate regions of America. The use of Hyptis spicigera Lam. (Lamiaceae) is reported in traditional medicine due to its gastroprotective, anti-inflammatory and analgesic properties. AIM OF THE STUDY The rationale of this study was to investigate the potential use of the essential oil of H. spicigera (EOHs) as analgesic. MATERIAL AND METHODS The antinociceptive effect of EOHs was verified analyzing acute nocifensive behavior of mice induced by chemical noxious stimuli [i.e., formalin and transient receptor potential (TRP) channels agonists]. We also verified the effects of EOHs on locomotor activity and motor performance in mice. Finally, we investigate the involvement of central afferent C-fibers with EOHs analgesic effect. RESULTS EOHs presented antinociceptive effect at 300 and 1000mg/kg on formalin-induced pain behavior model, presenting 50% and 72% of inhibition during the first phase (ED50 =292mg/kg), and 85% and 100% during de second phase (ED50 =205mg/kg), respectively. Temperature of the hind paw was reduced by EOHs treatment in a dose-dependent manner; oedema was diminished only by EOHs 1000mg/kg. EOHs does not impaired locomotor activity or motor performance. For mice injected with capsaicin, a TRPV1 activator, EOHs (1000mg/kg, ED50 =660mg/kg) showed decreased (63%) nociceptive behavior. When injected with cinnamaldehyde (TRPA1 activator), mice treated with EOHs showed 23%, 43% and 66% inhibition on nociceptive behavior (100, 300 and 1000mg/kg, respectively; ED50 402mg/kg). When mice were injected with menthol (TRPM8 activator), EOHs showed 29%, 59% and 98% inhibition of nociceptive behavior (100, 300 and 1000mg/kg, respectively; with ED50 =198mg/kg. Finally, when desensitized mice were injected with menthol, EOHs (300mg/kg) does not show antinociceptive effect. CONCLUSIONS This study demonstrated the efficacy of EOHs on experimental models of nociception. We have found the involvement of TRP channels V1, A1 and M8 with EOHs activity, which was remarkably potent and efficient in inhibiting pain evoked by menthol, a TRPM8 channel activator. TRPM8 channels from TRPV1+ C-fibers, but not TRPM8+ C-fibers nor TRPM8+ Aδ mechanosensory fibers, mediate EOHs analgesic effects.

Unravelling cortico-hypothalamic pathways regulating unconditioned fear-induced antinociception and defensive behaviours. Neuropharmacology 2016; 113:367-385.

Abstract
The medial prefrontal cortex can influence unconditioned fear-induced defensive mechanisms organised by diencephalic neurons that are under tonic GABAergic inhibition. The posterior hypothalamus (PH) is involved with anxiety- and panic attack-like responses. To understand this cortical mediation, our study characterised anterior cingulate cortex (ACC)-PH pathways and investigated the effect of ACC local inactivation with lidocaine. We also investigated the involvement of PH ionotropic glutamate receptors in the defensive behaviours and fear-induced antinociception by microinjecting NBQX (an AMPA/kainate receptor antagonist) and LY235959 (a NMDA receptor antagonist) into the PH. ACC pretreatment with lidocaine decreased the proaversive effect and antinociception evoked by GABAA receptor blockade in the PH, which suggests that there may be descending excitatory pathways from this cortical region to the PH. Microinjections of both NBQX and LY235959 into the PH also attenuated defensive and antinociceptive responses. This suggests that the blockade of AMPA/kainate and NMDA receptors reduces the activity of glutamatergic efferent pathways. Both inputs from the ACC to the PH and glutamatergic hypothalamic short links disinhibited by intra-hypothalamic GABAA receptors blockade are potentially implicated. Microinjection of a bidirectional neurotracer in the PH showed a Cg1-PH pathway and PH neuronal reciprocal connections with the periaqueductal grey matter. Microinjections of an antegrade neurotracer into the Cg1 showed axonal fibres and glutamatergic vesicle-immunoreactive terminal boutons surrounding both mediorostral-lateroposterior thalamic nucleus and PH neuronal perikarya. These data suggest a critical role played by ACC-PH glutamatergic pathways and AMPA/kainate and NMDA receptors in the panic attack-like reactions and antinociception organised by PH neurons.

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
It is well known that adenine-based purines exert multiple effects on pain transmission. Recently, we have demonstrated that guanine-based purines may produce some antinociceptive effects against chemical and thermal pain in mice. The present study was designed to investigate the antinociceptive effects of intrathecal (i.t.) administration of inosine or guanine in mice. Additionally, investigation into the mechanisms of action of these purines, their general toxicity and measurements of CSF purine levels were performed. Animals received an i.t. injection of vehicle (30mN NaOH), inosine or guanine (up to 600nmol) and submitted to several pain models and behavioural paradigms. Guanine and inosine produced dose-dependent antinociceptive effects in the tail-flick, hot-plate, intraplantar (i.pl.) glutamate, i.pl. capsaicin and acetic acid pain models. Additionally, i.t. inosine inhibited the biting behaviour induced by spinal injection of capsaicin and i.t. guanine reduced the biting behaviour induced by spinal injection of glutamate or AMPA. Intrathecal administration of inosine (200nmol) induced an approximately 115-fold increase on CSF inosine levels. This study provides new evidence on the mechanism of action of extracellular guanine and inosine presenting antinociceptive effects following spinal administration. These effects seem to be related, at least partially, to the modulation of A1 adenosine receptors.

Diacerein decreases visceral pain through inhibition of glutamatergic neurotransmission and cytokine signaling in mice. Pharmacol Biochem Behav 2012; 102:549-54.

Abstract
The present study evaluated the antinociceptive effect of the pro-inflammatory cytokines inhibitor diacerein in mice and its possible mechanism of action. The antinociception produced by diacerein was tested at different sites of action, moreover selective antagonists or agonists were used to identify the mechanism that may be involved in its antinociceptive action against acetic acid-induced visceral pain. Diacerein administered systemically (intraperitoneal [i.p.] or intra-gastric [i.g.] routes), supra-spinally (i.c.v.), spinally (i.t.) or peripherally (in association with the irritant agent) inhibited the visceral nociception induced by acetic acid in mice. Interestingly, diacerein treatment (25 mg/kg, i.p. or 50 mg/kg, i.g.) produced long-lasting (for up to 4 h) inhibition of acetic acid-induced nociception. Intraperitoneal treatment of mice with diacerein (25.0 mg/kg) inhibited somatic nociception induced by i.t. injection of glutamate, NMDA, kainate, and trans-ACPD but not that caused by AMPA. Diacerein (5.0-25.0 mg/kg) also produced dose related inhibition of interleukin-1β (IL-1β) and tumor necrosis factor alpha (TNF-α) induced nociception. These results indicate that diacerein produces antinociception by inhibiting glutamatergic transmission through both ionotropic and metabotropic receptors as well as activity of pro-inflammatory cytokines.

Abstract
Although the benefits are sometimes obvious, traditional or herbal medicine is regarded with skepticism, because the mechanism through which plant compounds exert their powers are largely elusive. Recent studies have shown however that many of these plant compounds interact with specific ion channels and thereby modulate the sensing mechanism of the human body. Especially members of the Transient Receptor Potential (TRP) channels have drawn large attention lately as the receptors for plant-derived compounds such as capsaicin and menthol. TRP channels constitute a large and diverse family of channel proteins that can serve as versatile sensors that allow individual cells and entire organisms to detect changes in their environment. For this family, a striking number of empirical views have turned into mechanism-based actions of natural compounds. In this review we will give an overview of herbal compounds and toxins, which modulate TRP channels.

Meotti FC, Coelho IDS, Santos ARS. The nociception induced by glutamate in mice is potentiated by protons released into the solution. THE JOURNAL OF PAIN 2010; 11:570-8.

Abstract
UNLABELLED In this study we compare the effect of a glutamate solution with pH adjusted to 7 (3-30 micromol/paw), a non-pH-adjusted glutamate solution (.3-30 micromol/paw, pH range 2.24-1.14), and an acid solution (2% acetic acid, pH 1.4-7) in terms of causing licking behavior in mice. The sum of licking seconds was recorded in the first 15 minutes following the intraplantar (i.pl.) injection of the solutions. Protons potentiated the nociception induced by glutamate. The ED(50) values were 2.5 (1.5-4.2) and 15.1 (11.5-19.9) micromol/paw for the non-pH-adjusted and pH-adjusted glutamate solutions, respectively. The acid solutions at pH 1.4, 2 and 4 induced a similar nociception. The blocking of the acid-sensitive ion channels (ASICs) by amiloride and the antagonism of the transient receptor potential vanilloid subtype-1 (TRPV1) by capsazepine, injected via i.pl., significantly decreased the nociception mediated by acid and by non-pH-adjusted glutamate solutions, but did not affect the nociception caused by the pH-adjusted glutamate solution. The pretreatment with the NMDA-receptor antagonist (MK-801, i.pl.), with the cyclooxygenase inhibitor (indomethacin, i.pl.) or the disruption of the sensorial C fibers by capsaicin, decreased the nociceptive effect of the 3 algogen tested. In summary, the protons present in aqueous solution of glutamate can cause nociception per se or can potentiate the nociception caused by glutamate. These effects are related to the activation of ASICs, TRPV1 and NMDA receptors, inhibition of the synthesis of prostanoids, and disruption of the C fibers. PERSPECTIVE The nociception induced by glutamate is a useful method for investigation of the mechanisms of nociception and the effects of new analgesic drugs. Our findings showed that the protons released from glutamic acid have to be removed from the solution to avoid misinterpretation of results in the search for new analgesic drugs.

Abstract
BACKGROUND In recent years, cyclic imides have attracted the attention of the scientific community because of their promising therapeutic potential. Studies with the compound N-antipyrine-3,4-dichloromaleimide (NA-3,4-DCM) also demonstrated an antinociceptive effect in formalin or capsaicin models of nociception, and that it reduced acetic acid-induced abdominal writhing in mice. METHODS In this study, we examined the effects of NA-3,4-DCM on mechanical hypernociception in persistent pain-like behavioral models in mice. We also investigated the peripheral, topical, spinal, and supraspinal antinociceptive properties of NA-3,4-DCM and evaluated the involvement of the glutamatergic system on the antinociceptive effects of NA-3,4-DCM in mice. RESULTS NA-3,4-DCM, dosed systemically (intraperitoneally or per os), was capable of interfering with the development of mechanical hypernociception induced by intraplantar injection of carrageenan and complete Freund adjuvant in mice. Interestingly, repeated intraperitoneal or per os treatment with NA-3,4-DCM, administered after the induction of hypernociception, also reversed the mechanical sensitization induced by complete Freund adjuvant injection or partial ligation of the sciatic nerve in mice, with lower doses than gabapentin, a drug used clinically to treat chronic pain. When administered systemically, locally, spinally, or supraspinally, NA-3,4-DCM was able to inhibit the overt nociception of both phases of the formalin test. The systemic administration of NA-3,4-DCM also reduced the nociception induced by intraplantar or intrathecal injection of glutamate in mice. Furthermore, NA-3,4-DCM caused marked inhibition of the nociceptive response induced by intrathecal injection of a group I metabotropic glutamate receptors agonist (1S,3R)-aminocyclopentane-trans-1,3-dicardboxylic acid (ACPD) or N-methyl-d-aspartate (NMDA), without interfering with nociception induced by other non-NMDA receptor agonists (alpha-amino-3-hydroxyl-5-methyl-4-isoxazole-propionic acid and kainate) or by substance P. Notably, in the same range of doses, the antinociception caused by the compound NA-3,4-DCM was not associated with nonspecific effects such as changes in locomotor activity or motor coordination. CONCLUSION These results provide strong evidence that NA-3,4-DCM produces antihypernociception in mice at peripheral, spinal, and supraspinal sites, and that interaction with the group I metabotropic glutamate receptors and NMDA receptors contributes to the mechanisms underlying its effect.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pfaffia glomerata (Spreng) Pedersen (Amaranthaceae) is a medicinal plant known in Brazil as "Paratudo" and "Brazilian ginseng" and is commonly used as tonic, antidiabetic and to treat gastric disorders. AIM OF THE STUDY This study evaluates the possible mechanism by which hydroalcoholic extract (HE) of Pfaffia glomerata exerts its antinociceptive effect. MATERIALS AND METHODS The HE was evaluated in acetic acid and glutamate models of pain or by biting behavior following intrathecal (i.t.) administration of agonists of excitatory aminoacids (EAA) receptors glutamate and pro-inflammatory cytokines, IL-1beta and TNF-alpha in mice. RESULTS Oral administration of HE produced dose-dependent inhibition of acetic acid-induced visceral pain and glutamate-induced pain, with ID(50) of 64.6 (47.7-87.5)mg/kg and ID(50) of 370.8 (253.4-542.7)mg/kg, respectively. The HE (300 mg/kg, p.o.) antinociception, in the acetic acid test, was not affected by i.p. treatment of animals with naloxone. In addition, HE (300 mg/kg, p.o.) inhibited the pain-related behaviors induced by i.t. injection of trans-ACPD and TNF-alpha, but not by NMDA, AMPA, kainate or IL-1beta. CONCLUSIONS Our results suggest that inhibition of glutamatergic metabotropic receptors and TNF-alpha may account for the antinociceptive action reported for the HE in models of chemical pain used in this study.

Abstract
(-)-Linalool is a monoterpene alcohol which is present in the essential oils of several aromatic plants. Recent studies suggest that (-)-linalool has anti-inflammatory, antihyperalgesic and antinociceptive properties in different animal models. The present study investigated the contribution of glutamatergic system in the antinociception elicited by (-)-linalool in mice. Nociceptive response was characterized by the time that the animal spent licking the injected hind paw or biting the target organ following glutamate receptor agonist injections. (-)-Linalool administered by intraperitoneal (i.p., 10-200 mg/kg), oral (p.o., 5-100 mg/kg) or intrathecal (i.t., 0.1-3 microg/site) routes dose-dependently inhibited glutamate-induced nociception (20 micromol/paw, pH 7.4) with ID(50) values of 139.1 mg/kg; 34.6 mg/kg; and 0.9 microg/site, with inhibitions of 70+/-4; 72+/-7 and 74+/-8%, respectively. However, the intraplantar injection of (-)-linalool partially (49+/-9%) inhibited glutamate-induced nociception. Furthermore, (-)-linalool (200 mg/kg) given i.p. also reduced significantly the biting response caused by intrathecal injection of glutamate (30 microg/site), AMPA (25 ng/site), SP (135 ng/site), NMDA (25 ng/site) and kainate (23.5 ng/site), with inhibitions of 89+/-6%, 73+/-11%, 85+/-4%, 98+/-2% and 52+/-15%, respectively. However, (-)-linalool did not inhibit nociception induced by intrathecal injection of trans-ACPD (8.6 microg/site). Taken together, these results provide experimental evidences indicating that (-)-linalool produce marked antinociception against glutamate induced pain in mice, possible due mechanisms operated by ionotropic glutamate receptors, namely AMPA, NMDA and kainate.

Abstract
Ankyrin-repeat transient receptor potential 1 (TRPA1) is a member of the transient receptor potential (TRP) channel family and it is found in sensory neurons. In the present study, we found that TRPA1 receptor activation with allyl isothiocyanate or cinnamaldehyde caused dose-dependent spontaneous nociception when injected into the mouse hind paw. Very similar results were obtained when stimulating transient receptor potential vanilloid 1 (TRPV1) receptors with capsaicin. Pretreatment with the TRP receptor antagonist Ruthenium Red (1 nmol/paw) inhibited capsaicin-(0.1 nmol/paw) and allyl isothiocyanate-(1 nmol/paw) induced nociceptive responses. However, the nonselective TRPV1 receptor antagonist capsazepine (1 nmol/paw) and the selective TRPV1 receptor antagonist SB 366791 (1 nmol/paw) only attenuated capsaicin-induced nociception. In contrast, the intrathecal treatment with TRPA1 antisense oligodeoxynucleotide (2.5 nmol/site) and the degeneration of the subset of primary afferent fibers sensitive to capsaicin significantly reduced allyl isothiocyanate-induced nociception. Consequently to TRPA1 antisense oligodeoxynucleotide treatment there was a marked decrease of the expression of TRPA1 receptor in both sciatic nervous and spinal cord segments. Moreover, capsaicin and allyl isothiocyanate-induced nociception were not significantly changed by chemical sympathectomy produced by guanethidine. The previous degranulation of mast cells by compound 48/80 and treatment with antagonist H(1) receptor antagonist pyrilamine (400 microg/paw) both significantly inhibited the capsaicin- and allyl isothiocyanate-induced nociception. The selective NK(1) receptor antagonist N(2)-[(4R)-4-hydroxy-1-(1-methyl-1H-indol-3-yl) carbony-1-L-prolyl]-N-methyl-N-phenylmethyl-3-2-(2-naphtyl)-L-alaninamide (10 nmol/paw) reduced either capsaicin- or allyl isothiocyanate-induced nociception. Collectively, the present findings demonstrate that the TRPA1 agonist allyl isothiocyanate produces a consistent nociceptive response when injected into the mouse paw, an effect that seems to be mediated via activation of TRPA1 receptor and dependent on the capsaicin-sensitive fibers, release of histamine by mast cells and participation of tachykinins. Thus, the TRPA1 receptor has an apparently relevant role in nociceptive processes and the selective TRPA1 antagonist might possess a potential antinociceptive property.

Abstract
Humirianthera ampla Miers is a member of the Icacinaceae family and presents great amounts of di and triterpenoids. These chemical constituents in roots of Humirianthera ampla sustain not only the ethnopharmacological use against snake venom, but also some anti-inflammatory and analgesic properties of the plant. In this study we investigated the antinociceptive action of the ethanolic extract (EE) from roots of the Humirianthera ampla in chemical and thermal models of pain in mice. The oral treatment with ethanolic extract dose-dependently inhibited glutamate-, capsaicin- and formalin-induced licking. However, it did not prevent the nociception caused by radiant heat on the tail-flick test. The ethanolic extract (30 mg/kg) caused marked inhibition of the nociceptive biting response induced by glutamate, (+/-)-1-aminocyclopentane-trans-1,3-dicarboxylic acid (trans-ACPD), N-methyl-d-aspartate (NMDA) and substance P. The antinociception caused by ethanolic extract was significantly attenuated by naloxone, l-arginine, WAY100635, ondansetron or ketanserin, but not by caffeine or naloxone methiodide. In conclusion, the ethanolic extract from roots of Humirianthera ampla produces antinociception against neurogenic and inflammatory models of nociception. The mechanisms of antinociception involve nitric oxide, opioid, serotonin and glutamate pathways. Therefore, our results support the ethnopharmacological use of the Humirianthera ampla against inflammatory and painful process caused by snake venom.

Abstract
The present study was designed to investigate the mechanisms involved in the antinociception afforded by myricitrin in chemical models of nociception in mice. Myricitrin given by intrathecal (i.t.) or intracerebroventricular (i.c.v.) route produced dose-related antinociception when evaluated against acetic acid-induced visceral pain in mice. In addition, the intraperitoneal administration of myricitrin caused significant inhibition of biting behaviour induced by i.t. injection of glutamate, substance P, capsaicin, interleukin 1 beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha). The antinociception caused by myricitrin in the acetic acid test was fully prevented by i.t. pre-treatment with pertussis toxin, a Gi/o protein inactivator, and by i.c.v. injection of calcium chloride (CaCl(2)). In addition, the i.t. pre-treatment of mice with apamin, a blocker of small (or low)-conductance calcium-gated K(+) channels and tetraethylammonium, a blocker of voltage-gated K(+) channels significantly reversed the antinociception induced by myricitrin. The charybdotoxin, a blocker of large (or fast)-conductance calcium-gated K(+) channels and glibenclamide, a blocker of the ATP-gated K(+) channels had no effect on myricitrin-induced antinociception. Calcium uptake analysis revealed that myricitrin inhibited (45)Ca(2+) influx under a K(+)-induced depolarization condition. However, calcium movement was modified in a non-depolarizing condition only when the highest concentration of myricitrin was used. In summary, our findings indicate that myricitrin produces consistent antinociception in chemical models of nociception in mice. These results clearly demonstrate an involvement of the Gi/o protein dependent mechanism on antinociception caused by myricitrin. The opening of voltage- and small-conductance calcium-gated K(+) channels and the reduction of calcium influx led to the antinociceptive of myricitrin.

Abstract
Natural products, including those derived from plants, have largely contributed to the development of therapeutic drugs. Glutamate is the main excitatory neurotransmitter in the central nervous system and it is also considered a nociceptive neurotransmitter, by acting on peripheral nervous system. For this reason, in this study we investigated the effects of the hydroalcoholic extracts from Drymis winteri (polygodial and drimanial), Phyllanthus (rutin and quercetine), Jathopha elliptica (jatrophone), Hedyosmum brasiliense (13HDS), Ocotea suaveolens (Tormentic acid), Protium kleinii (alphabeta-amyrin), Citrus paradise (naringin), soybean (genistein) and Crataeva nurvala (lupeol), described as having antinociceptive effects, on glutamatergic transmission parameters, such as [(3)H]glutamate binding, [(3)H]glutamate uptake by synaptic vesicles and astrocyte cultures, and synaptosomal [(3)H]glutamate release. All the glutamatergic parameters were affected by one or more of these compounds. Specifically, drimanial and polygodial presented more broad and profound effects, requiring more investigation on their mechanisms. The putative central side effects of these compounds, via the glutamatergic system, are discussed.

Abstract
Drimys angustifolia Miers. (Winteraceae) is a Brazilian medicinal plant used as analgesic, antiulcer and anti-inflammatory without studies to assure its efficacy and safety Leaf and stem bark extracts were evaluated to determine the antiulcer, analgesic, antiinflammatory and antioxidant activities. Preliminary toxic effects and qualitative phytochemical profile were also performed. The antiulcer activity was detected in both extracts. Administration of the leaf extract at 250 mg/kg inhibited total lesion area by 76.50% (p < 0.01 in ethanol/HCl method), while carbenoxolone at 250 mg/kg reduced lesions by 69.48%. Stem bark extract (250 mg/kg) inhibited lesion by 81.42%, while carbenoxolone by 74.10%. Similar effects were observed in the ethanol-induced ulcer method, but no activity was observed in piroxican model. The effects involve nitric oxide in gastric protection, since the L-NAME treatment reversed the protection given by the extracts. Antioxidant effects suggest an involvement against oxidative stress. In the pain (writhing, tail-flick and hot-plate tests) and inflammation (carrageenan-induced paw edema) models, the extracts did not present any effect. The phytochemical studies demonstrated that both extracts contain flavonoids, saponins, glycosilated triterpenoids, fixed acids, cyanogenic glycosides, quinones, tannins, xanthone and steroidal aglycones. Toxicological studies showed that the extracts are safe at the effective antiulcer doses.

Abstract
This study was designed to evaluate the role of spinal glutamatergic receptors in the antinociception elicited by agmatine in mice. Intraperitoneal (i.p.) administration of agmatine (1.0-100.0 mg/kg) dose dependently inhibited the nociceptive response induced by intrathecal (i.t.) injection of glutamate, N-methy-D-aspartate (NMDA) and (+/-)-1-aminocyclopentane-trans-1,3-dicarboxylic acid (trans-ACPD), with mean ID(50) values of 16.7, 6.8 and 27.0 mg/kg, respectively. However, agmatine completely failed to affect the nociception induced by alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) or kainic acid (kainate). Agmatine injected by i.t. route (10-100 microg/site) also produced dose-related inhibition of NMDA- and trans-ACPD-induced biting response with mean ID(50) values of 29.6 and 36.0 mug/site, respectively. The nitric oxide synthase inhibitor N(omega)-nitro-L-arginine (l-NOARG) (75.0 mg/kg, i.p.) also consistently inhibited glutamate-, NMDA- and trans-ACPD-induced nociception (41 +/- 13, 100 and 83 +/- 6%, of inhibition, respectively) but had no effect on the same response caused by AMPA and kainate agonists. The selective NMDA receptor antagonist (5S,10R)-(+)-5-Methyl-10,11-dihydro-5H-dibenzo[a,d] (MK-801) at a low dose (0.05 mg/kg, i.p.) inhibited the nociceptive response caused by both glutamate and NMDA agonists (inhibitions of 35 +/- 1 and 72 +/- 2%, respectively). At a high dose, MK-801 (0.5 mg/kg, i.p.) significantly inhibited the biting response induced by i.t. administration of all the glutamatergic agonists tested: glutamate, AMPA, NMDA, kainate and trans-ACPD, with inhibitions of 49 +/- 8, 84 +/- 16, 84 +/- 3, 76 +/- 8 and 97 +/- 2%, respectively. Together, these results provide experimental evidence indicating that agmatine given systemically and spinally produce marked antinociception at spinal sites in mice. Furthermore, an interaction with glutamate receptors, namely NMDA and trans-ACPD, metabotropic and NMDA-ionotropic origin, by a mechanism similar to that of nitric oxide (NO) inhibitors, seems to account for the agmatine antinociceptive action.

Abstract
Natural products including those derived from plants, have over the years greatly contributed to the development of therapeutic drugs. Polygodial and drimanial are sesquiterpenes isolated from the bark of the plant Drymis Winteri (Winteraceae) that exhibit antinociceptive properties. Since peripheral glutamate presents nociceptive actions, in this study it was investigated the effects of hydroalcooholic extracts from Drymis winteri (polygodial and drimanial) on the glutamatergic system in rat brain. Polygodial and drimanial inhibited glutamate uptake by astrocytes, as well as by cortical, hippocampal and striatal slices, and increased synaptosomal glutamate release. These concurrent effects would predispose to an increase in the extracellular glutamate concentrations, leading to possible neurotoxic effects (excitotoxicity) of these natural compounds, which would suggest the need for some caution in their therapeutic application.

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
The chemical composition of the chromatography 63 subfraction (63SF) from the ethyl acetate soluble fraction of the crude extract of Croton celtidifolius bark presented a high content of total proanthocyanidins (75.0+/-2.3%). HPLC analysis of 63SF revealed a dimeric profile (e.g.catechin-(4alpha-->8)-catechin and gallocatechin-(4alpha-->8)-catechin) and polymeric proanthocyanidins. In pharmacological investigations, 63SF administered intraperitoneally exhibited dose-dependent antinociceptive activity against several chemical stimuli, including the intraperitoneal injection of acetic acid (ID50 (the dose of 63SF which was able to reduce the nociceptive response by 50% relative to the control value)=0.9 (0.5-1.6)) and the intraplantar injection of capsaicin (ID50=13.0 (10.0-17.0)), glutamate (ID50=4.0 (2.0-7.0)) and formalin (ID50 first phase=36.0 (24.0-53.0) and late phase=11.0 (8.0-14.0)). 63SF administered orally exhibited an antinociceptive effect in the formalin test (ID50 first phase=125.0 (89.0-177.0) and late phase=65.0 (33.0-95.0)). In the same test, 63SF was effective when given soon after the first phase, as well as exhibiting therapeutic activity. Furthermore, 63SF was effective in models of thermal nociception including tail-flick and hot-plate tests. When the mice were treated in the neonatal period with capsaicin, the antinociceptive effect of 63SF in the first phase of the formalin test was abolished, but pretreatment with naltrexone did not change the antinociceptive effect of 63SF. Together, these results provide evidence that 63SF exerted a pronounced systemic antinociception against chemical (acetic acid, formalin, glutamate and capsaicin tests) and thermal (hot-plate and tail-flick tests) nociceptive models of pain in mice at a dose that did not interfere with the locomotor activity. The mechanism by which this sub-fraction produced antinociception remains unclear, but it is unlikely to involve the activation of the opioid system. However, unmyelinated C-fibres sensitive to treatment with capsaicin are likely to participate in antinociception caused by 63SF.

Abstract
This study examined the role of glutamatergic system in the ascorbic acid (AA)-induced antinociception in chemical behavioural models of nociception in mice. AA (0.3-10 mg/kg, i.p.) produced significant inhibition of both phases of formalin-induced licking, with mean ID50 values of 4.0 and 3.2 mg/kg and inhibitions of 56+/-4 and 60+/-7% for the early and second phase of the nociception caused by formalin, respectively. AA (1-5 mg/kg, i.p.) also produced significant inhibition of glutamate-induced nociception with mean ID50 value of 2.1 mg/kg and inhibition of 66+/-5%. Furthermore, AA (3 mg/kg, i.p.) caused marked inhibition of nociceptive response induced by intrathecal injection of glutamate, NMDA, AMPA, kainate and substance P, with inhibitions of 49+/-9, 42+/-7, 34+/-8, 38+/-5 and 65+/-8%, respectively. In contrast, AA at the same dose did not affect the biting response induced by the metabotropic agonist trans-ACPD. Taken together, present results indicate that AA, at low systemic doses, produces a rapid onset and consistent antinociception in mice when assessed in several models of chemical nociception, an action that is likely mediated by an interaction with ionotropic, but not metabotropic, glutamate receptors.

Abstract
This study aimed to investigate further the mechanisms involved in the antinociception caused by dipyrone, given by intraperitoneal (i.p.) or intrathecal (i.t.) routes. The intraperitoneal administration of dipyrone to mice 30 min prior resulted in a significant and dose-related inhibition of the biting responses induced by i.t. injection of glutamate, trans-ACPD or substance P (SP). In addition, dipyrone given by i.t. route, 15 min before glutamate, trans-ACPD or SP, also produced a significant reduction in their nociceptive effects. In addition, dipyrone given by i.t. route, 15 min before glutamate, trans-ACPD or SP, also produced a significant reduction in their nociceptive effects. Dipyrone, given either systemically (i.p.) or by i.t. route also caused a dose-dependent inhibition of phorbol myristate acetate (PMA)-induced nociception. Given by systemic route, dipyrone inhibited PMA-induced paw oedema formation. Collectively, these results extend previous data from our group indicating that glutamatergic-mediated pain responses, specifically those mediated by metabotropic receptor subtype, together with inhibition of neurokinin NK(1)-mediated response, account for the antinociceptive action of dipyrone in mice. Furthermore, we have also produced experimental evidence indicating that the activation of the protein kinase C-dependent pathway plays a role in the dipyrone antinociceptive action.

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.
