Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Eugenia uniflora Linn, popularly known as 'pitanga', is a native plant endemic to Brazil that belongs to the Myrtaceae family. Its traditional use (leaves infusion) has been reported for the treatment of different diseases, including hypertension, inflammation, and as a diuretic agent. Considering the snakebite problem and the rich molecule repertoire of this herbal species, studies that evaluate its antiophidic potential are relevant for a broad social impact. AIM OF THE STUDY This approach aims to evaluate the anti-inflammatory and antiophidic potential in vitro and in vivo of the extract (aqueous) and a fraction (ethyl acetate) of E. uniflora leaves against Bothrops leucurus and Bothrops brazili venoms. MATERIALS AND METHODS Extract and fraction from E. uniflora leaves were obtained by turbo-extraction and partitioning. The cytotoxicity was assayed on normal cell lines (Vero E6 and 3T3) using the 3-methyl-[4-5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide method. The anti-inflammatory activity of the aqueous extract was analyzed in vivo in the zymosan-induced air pouch model, and the leukocytes migration and other molecular inflammatory mediators quantified (myeloperoxidase, total protein, pro-inflammatory cytokine, malondialdehyde, and glutathione). In vitro, the antiophidic effect was evaluated by the ability of the E. uniflora extract and fraction to inhibit the enzymatic action (proteolytic, phospholipase A2, and hyaluronidase) of B. leucurus and B. brazili venoms. In addition, the antiophidic action in vivo was investigated after treatment with E. uniflora extract and fraction (50, 100, and 200 mg/kg) in the B. leucurus venom-induced paw edema with an evaluation of the antiedematogenic effect and quantification of myeloperoxidase (MPO) and pro-inflammatory cytokine levels. RESULTS The E. uniflora leaves extract (7.8-125 mg/mL) revealed no toxicity in cell culture, but reduced MTT by 47% at the highest concentration (250 mg/mL) in Vero E6 cells. In contrast, the E. uniflora fraction (7.8-250 mg/mL) showed no cytotoxicity for both cell lines. In the air pouch model, E. uniflora leaves extract demonstrated anti-inflammatory activity, reducing cell migration, MPO activity, protein, malondialdehyde, and proinflammatory cytokines, and increased glutathione levels. Evaluating the antiophidic action in vitro, E. uniflora extract and fraction inhibited the proteolytic, phospholipase, and hyaluronidase effects of B. leucurus and B. brazili venoms at low concentrations. In addition, the extract and fraction also demonstrated in vivo antiophidic activity by reducing edema in the first 0.5 h after treatment, besides reducing MPO and pro-inflammatory cytokines levels. CONCLUSION E. uniflora leaves extract showed cytotoxicity only at the highest concentration while the fraction revealed no toxic effect in vitro. This approach showed for the first time that the aqueous extract and ethyl acetate fraction of E. uniflora leaves has similar antiophidic action in vitro and in vivo, with antiedematogenic and anti-inflammatory effects and the ability to inhibit the enzymatic action of B. leucurus and B. brazili venoms. Therefore, this study points to the presence of bioactive components in the leaves of E. uniflora useful for the treatment of inflammatory disorders and ophidian accidents, expanding the therapeutic potential of this herbal species.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Brazil, there are species of snakes that become involved in accidents and cause serious health problems to the inhabitants, highlighting the genus Bothrops for being responsible for approximately 90% of accidents reported annually. In the northern region of the country, this genus is responsible for the largest number of accidents, especially among rural dwellers. These populations invest in alternative treatments for with the purpose of improving the symptoms caused by snakebites. The species Mauritia flexuosa L. f., known as buriti, is traditionally used for the treatment of envenomation by snakes. AIM OF THE STUDY This study aimed to evaluate the antiophidic potential of the oil of Mauritia flexuosa L. f. for Bothrops moojeni H. venom, confronting cultural and scientific knowledge. MATERIALS AND METHODS The physicochemical properties were determined, and the components present in the oil, extracted from fruit pulp, were analyzed by Gas Chromatography Coupled with Mass Spectrometry. The in vitro inhibitory capacity of the oil for phospholipase, metalloprotease and serine protease activities was investigated. In the in vivo studies, male Swiss mice were used to evaluate the effect of oil on lethality and toxicity, and hemorrhagic, myotoxic and edematogenic activities were assessed. RESULTS GC‒MS analysis identification of 90.95% of the constituents of the oil, with the main components being 9-eicosenoic acid, (Z)- (34.54%), n-hexadecanoic acid (25.55%) and (E)-9-octadecenoic acid ethyl ester (12.43%). For the substrates, the outcomes indicate that the oil inhibited the activity of the main classes of toxins present in Bothrops moojeni H. venom (VBm) at the highest dose tested (0.5 μL), with inhibition of 84% for the hydrolysis of the selective substrate for serine protease and inhibition of 60% for the hydrolysis of substrates for PLA2 and metalloproteases. The antiophidic activity in vivo was evaluated with two concentrations of the oil: 1.5 mg, the dosage the population, diluted in mineral oil to a volume of 1 tablespoon and 15 mg, administered by gavage 30 min before poisoning and at time zero (concomitant to poisoning), and both concentrations administered by gavage in combination with topical use at time zero. The bleeding time in the group treated with oil at a concentration of 15 mg administered at time zero was significantly lower than that in the control group (p < 0.05). However, a greater inhibition of bleeding time was observed when local application was combined with the gavage treatment at both concentrations tested at time zero (p < 0.05). In the myotoxicity test, oil was efficient in reducing the myotoxic effects induced by the venom at the two concentrations tested, with gavage administration at time zero and gavage plus topical administration at time zero (p < 0.05). CONCLUSIONS The data obtained show that the oil is safe to use at the concentrations studied and contains fatty acids that may collaborate for cellular-level repair of the injuries caused by Bm poisoning. The in vitro and in vivo experiments showed that oil inhibits the main proteolytic enzymes present in the venom and that it has important activities to control the local effects caused by bothropic venom.

Abstract
We investigated the antiophidic properties of isohemigossypolone (ISO), a naphthoquinone isolated from the outer bark of the Pachira aquatic Aubl. The inhibition of phospholipase A2, coagulant, fibrinogenolytic, hemorrhagic and myotoxic activities induced by Bothrops pauloensis venom (Pb) was investigated. For this, we use samples resulting from the incubation of Pb with ISO in different concentrations (1:1, 1:5 and 1:10 w/w), we also evaluated the condition of treatment using ISO after 15 min of venom inoculation. The activities of phospholipase A2, coagulant, fibrinogenolytic, hemorrhagic and myotoxic induced by the B. pauloensis venom were significantly inhibited when the ISO was pre-incubated with the crude venom. For in vivo neutralization tests, the results were observed even when the ISO was applied after 15 min of inoculation of the venom or metalloprotease (BthMP). Also, to identify the inhibition mechanism, we performed in silico assays, across simulations of molecular coupling and molecular dynamics, it was possible to identify the modes of interaction between ISO and bothropic toxins BmooMPα-I, Jararacussin-I and BNSP-7. The present study shows that naphthoquinone isohemigossypolone isolated from the P. aquatica plant inhibited part of the local and systemic damage caused by venom proteins, demonstrating the pharmacological potential of this compound in neutralizing the harmful effects caused by snakebites.

Abstract
Previous studies have demonstrated the potential antiophidic activity of Zanthoxylum monogynum A.St.-Hil. a tree from the Rutaceae family native to South America. In this present contribution, we demonstrate the activity of the metabolite lupeol, a triterpenoid isolated from the stem bark of Z. monogynum against the harmful effects of the Bothrops alternatus venom. We investigated the antiophidic properties of lupeol, for this purpose, and use crude venom (Pb) incubated with lupeol in different concentrations, testing in vitro experiments and inoculated in mice for inhibitory evaluations in vivo. Besides, we tried to elucidate through the molecular dynamics the mechanism of action of lupeol with the bothropic thrombin-like toxin Jararacussin-I; the acidic phospholipase A2 toxin BthA-I from Bothrops jararacussu and the metalloproteinase toxin BmooMP-I from Bothrops moojeni. In our results, we demonstrated the potential inhibitory effect upon coagulant, phospholipasic and myotoxic activities of the bothropic venom, previously incubated with lupeol. We found that lupeol triterpenoid was able to partially inhibit local and systemic damage caused by snake venom toxins. Our in silico results demonstrate that lupeol is capable of interacting and altering the activity of the thrombin-like toxin Jararacussin-I, and capable of interacting with the BthA-I acidic PLA2, both toxins present in Bothrops snakes venom, thus demonstrating the pharmacological potential of this compound for the treatment of bothropic accidents.

Abstract
Snakebite envenomation is a serious public health concern in rural areas of Uganda. Snakebites are poorly documented in Uganda because most occur in rural settings where traditional therapists end up being the first-line defense for treatment. Ethnobotanical surveys in Uganda have reported that some plants are used to antagonize the activity of various snake venoms. This review was sought to identify antivenin plants in Uganda and some pharmacological evidence supporting their use. A literature survey done in multidisciplinary databases revealed that 77 plant species belonging to 65 genera and 42 families are used for the treatment of snakebites in Uganda. The majority of these species belong to family Fabaceae (31%), Euphorbiaceae (14%), Asteraceae (12%), Amaryllidaceae (10%) and Solanaceae (10%). The main growth habit of the species is shrubs (41%), trees (33%) and herbs (18%). Antivenin extracts are usually prepared from roots (54%) and leaves (23%) through decoctions, infusions, powders, and juices, and are administered orally (67%) or applied topically (17%). The most frequently encountered species were Allium cepa, Carica papaya, Securidaca longipedunculata, Harrisonia abyssinica, and Nicotiana tabacum. Species with global reports of tested antivenom activity included Allium cepa, Allium sativum, Basella alba, Capparis tomentosa, Carica papaya, Cassia occidentalis, Jatropa carcus, Vernonia cinereal, Bidens pilosa, Hoslundia opposita, Maytensus senegalensis, Securinega virosa, and Solanum incanum. There is need to identify and evaluate the antivenom compounds in the claimed plants.

Abstract
BACKGROUND Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities. This study aimed to evaluate toxicological activities and potential as antitumor and antiophidic agents contained in total extracts from five cnidarians: Millepora alcicornis, Stichodactyla helianthus, Plexaura homomalla, Bartholomea annulata and Condylactis gigantea (total and body wall). METHODS The cnidarian extracts were evaluated by electrophoresis and for their phospholipase, proteolytic, hemorrhagic, coagulant, fibrinogenolytic, neuromuscular blocking, muscle-damaging, edema-inducing and cytotoxic activities. RESULTS All cnidarian extracts showed indirect hemolytic activity, but only S. helianthus induced direct hemolysis and neurotoxic effect. However, the hydrolysis of NBD-PC, a PLA2 substrate, was presented only by the C. gigantea (body wall) and S. helianthus. The extracts from P. homomalla and S. helianthus induced edema, while only C. gigantea and S. helianthus showed intensified myotoxic activity. The proteolytic activity upon casein and fibrinogen was presented mainly by B. annulata extract and all were unable to induce hemorrhage or fibrinogen coagulation. Cnidarian extracts were able to neutralize clotting induced by Bothrops jararacussu snake venom, except M. alcicornis. All cnidarian extracts were able to inhibit hemorrhagic activity induced by Bothrops moojeni venom. Only the C. gigantea (body wall) inhibited thrombin-induced coagulation. All cnidarian extracts showed antitumor effect against Jurkat cells, of which C. gigantea (body wall) and S. helianthus were the most active; however, only C. gigantea (body wall) and M. alcicornis were active against B16F10 cells. CONCLUSION The cnidarian extracts analyzed showed relevant in vitro inhibitory potential over the activities induced by Bothrops venoms; these results may contribute to elucidate the possible mechanisms of interaction between cnidarian extracts and snake venoms.
