Sequential randomised and double blind trial of promethazine prophylaxis against early anaphylactic reactions to antivenom for bothrops snake bites. (1/183)

OBJECTIVE: To investigate the efficacy of the H1 antihistamine promethazine against early anaphylactic reactions to antivenom. DESIGN: Sequential randomised, double blind, placebo controlled trial. SETTING: Public hospital in a venom research institute, Sao Paulo, Brazil. PARTICIPANTS: 101 patients requiring antivenom treatment after being bitten by bothrops snakes. INTERVENTION: Intramuscular injection of promethazine (25 mg for adults and 0.5/kg for children) or placebo given 15-20 min before starting intravenous infusion of antivenom. MAIN OUTCOME MEASURES: Incidence and severity of anaphylactic reactions occurring within 24 hours after antivenom. RESULTS: Reactions occurred in 12 of 49 patients treated with promethazine (24%) and in 13 of 52 given placebo (25%); most were mild or moderate. Continuous sequential analysis indicated that the study could be interrupted at the 22nd untied pair, without preference for promethazine or placebo. CONCLUSION: Prophylaxis with promethazine does not prevent early reactions. Patients should be observed carefully during antivenom infusion and the subsequent few hours.  (+info)

Crystallization and preliminary X-ray diffraction analysis of a myotoxic phospholipase A(2) homologue from Bothrops neuwiedi pauloensis venom. (2/183)

"RKKH" peptides from the snake venom metalloproteinase of Bothrops jararaca bind near the metal ion-dependent adhesion site of the human integrin alpha(2) I-domain. (3/183)

Integrin alpha(1)beta(1) and alpha(2)beta(1) are the major cellular receptors for collagen, and collagens bind to these integrins at the inserted I-domain in their alpha subunit. We have previously shown that a cyclic peptide derived from the metalloproteinase domain of the snake venom protein jararhagin blocks the collagen-binding function of the alpha(2) I-domain. Here, we have optimized the structure of the peptide and identified the site where the peptide binds to the alpha(2) I-domain. The peptide sequence Arg-Lys-Lys-His is critical for recognition by the I-domain, and five negatively charged residues surrounding the "metal ion-dependent adhesion site" (MIDAS) of the I-domain, when mutated, show significantly impaired binding of the peptide. Removal of helix alphaC, located along one side of the MIDAS and suggested to be involved in collagen-binding in these I-domains, does not affect peptide binding. This study supports the notion that the metalloproteinase initially binds to the alpha(2) I-domain at a location distant from the active site of the protease, thus blocking collagen binding to the adhesion molecule in the vicinity of the MIDAS, while at the same time leaving the active site free to degrade nearby proteins, the closest being the beta(1) subunit of the alpha(2)beta(1) cell-surface integrin itself.  (+info)

Histologic and functional renal alterations caused by Bothrops moojeni snake venom in rats. (4/183)

Acute renal failure (ARF) is the main cause of death following snake bites by Bothrops species. In this study, we investigated the morphologic and functional renal disturbances caused by Bothrops moojeni venom in rats. Renal function was assessed based on creatinine and lithium clearances and on histologic examination of renal tissue 5 hr after the intravenous administration of 0.2 mg of venom/kg and 5 hr, 16 hr, and 48 hr after 0.4 mg of venom/ kg. A venom dose of 0.4 mg/kg produced renal tubule disturbances, including acute impairment of proximal and post-proximal tubule sodium handling associated with acute tubule necrosis. The glomerular filtration rate (GFR) decreased significantly and was accompanied by severe morphologic disturbances in the renal glomeruli. These functional and morphologic findings were observed in the absence of any change in mean arterial blood pressure. The decrease in GFR was not related to the presence of fibrin deposits in the glomerular capillary loops. These results suggest an early nephrotoxic action of B. moojeni venom involving significant morphologic and functional changes similar to those observed in snakebite-induced ARF in humans.  (+info)

Two phospholipase A2 inhibitors from the plasma of Cerrophidion (Bothrops) godmani which selectively inhibit two different group-II phospholipase A2 myotoxins from its own venom: isolation, molecular cloning and biological properties. (5/183)

Myotoxic phospholipases A(2) (PLA(2)s; group II) account for most of the muscle-tissue damage that results from envenomation by viperid snakes. In the venom of the Godman's viper (Cerrophidion godmani, formerly Bothrops godmani), an enzymically active PLA(2) (myotoxin I) and an inactive, Lys-49 variant (myotoxin II) induce extensive muscle damage and oedema. In this study, two distinct myotoxin inhibitor proteins of C. godmani, CgMIP-I and CgMIP-II, were purified directly from blood plasma by selective binding to affinity columns containing either myotoxin I or myotoxin II, respectively. Both proteins are glycosylated, acidic (pI=4) and composed of 20-25-kDa subunits that form oligomers of 110 kDa (CgMIP-I) or 180 kDa (CgMIP-II). In inhibition studies, CgMIP-I specifically neutralized the PLA(2) and the myotoxic, oedema-forming and cytolytic activities of myotoxins I, whereas CgMIP-II selectively inhibited the toxic properties of myotoxin II. N-terminal amino acid sequence analysis and sequencing of cDNAs encoding the two inhibitors revealed that CgMIP-I is similar to gamma-type inhibitors, which share a pattern of cysteine residues present in the Ly-6 superfamily of proteins, whereas CgMIP-II shares sequence identity with alpha-type inhibitors that contain carbohydrate-recognition-like domains, also found in C-type lectins and mammalian PLA(2) receptors. N-terminal sequencing of myotoxin I revealed a different primary structure from myotoxin II [De Sousa, Morhy, Arni, Ward, Diaz and Gutierrez (1998) Biochim. Biophys. Acta 1384, 204-208], which provides insight into the nature of such pharmacological specificity.  (+info)

Antibody from mice immunized with DNA encoding the carboxyl-disintegrin and cysteine-rich domain (JD9) of the haemorrhagic metalloprotease, Jararhagin, inhibits the main lethal component of viper venom. (6/183)

Envenoming by the Brazilian pit viper, Bothrops jararaca, induces extensive local and systemic haemorrhage in humans. The severe and occasionally lethal outcome of envenoming is prevented only by administration of antivenom which is conventionally prepared by hyperimmunization of large animals with an individual venom or a range of venoms. Since snake venoms typically consist of numerous molecules, only some of which are toxic, antivenoms are antigenically crude preparations whose therapeutic value would theoretically be enhanced by restricting antibody specificity to toxic venom molecules. We report here that high-titre IgG antibody from mice immunized by the GeneGun with DNA encoding the carboxy-terminal JD9 domain of Jararhagin, a haemorrhage-inducing metalloprotease in B. jararaca venom, extensively neutralized the main lethal component of B. jararaca venom. This is to our knowledge the first study to apply DNA-based methods to preparation of antivenom; it represents a novel approach with greater immunological specificity and fewer hazards than conventional systems of antivenom production.  (+info)

Basic residues of human group IIA phospholipase A2 are important for binding to factor Xa and prothrombinase inhibition comparison with other mammalian secreted phospholipases A2. (7/183)

Human secreted group IIA phospholipase A2 (hGIIA) was reported to inhibit prothrombinase activity because of binding to factor Xa. This study further shows that hGIIA and its catalytically inactive H48Q mutant prolong the lag time of thrombin generation in human platelet-rich plasma with similar efficiency, indicating that hGIIA exerts an anticoagulant effect independently of phospholipid hydrolysis under ex vivo conditions. Charge reversal of basic residues on the interfacial binding surface (IBS) of hGIIA leads to decreased ability to inhibit prothrombinase activity, which correlates with a reduced affinity for factor Xa, as determined by surface plasmon resonance. Mutation of other surface-exposed basic residues, hydrophobic residues on the IBS, and His48, does not affect the ability of hGIIA to inhibit prothrombinase activity and bind to factor Xa. Other basic, but not neutral or acidic, mammalian secreted phospholipases A2 (sPLA2s) exert a phospholipid-independent inhibitory effect on prothrombinase activity, suggesting that these basic sPLA2s also bind to factor Xa. In conclusion, this study demonstrates that the anticoagulant effect of hGIIA is independent of phospholipid hydrolysis and is based on its interaction with factor Xa, leading to prothrombinase inhibition, even under ex vivo conditions. This study also shows that such an interaction involves basic residues located on the IBS of hGIIA, and suggests that other basic mammalian sPLA2s may also inhibit blood coagulation by a similar mechanism to that described for hGIIA.  (+info)

Local haemorrhage induced by Bothrops jararaca venom: relationship to neurogenic inflammation. (8/183)

We investigated morphological alterations induced by s.c. injection of 2.5 microg of Bothrops jararaca venom in rats. Intense disorganisation of collagen fibres was observed 1 min after the venom injection, particularly at regions near vessels and nerves. Mast cells were degranulated, and erythrocytes were seen leaving venules throughout the endothelial junctions. At this time, damaged endothelial cells were not observed. In rats envenomed as above, but immediately after cardiorespiratory failure induced by deep ether anaesthesia, alterations in the connective tissue structures, as previously described, were not observed. The mediation of this haemorrhage was investigated by injecting the venom into the foot pad of mice and compared to the mediation of oedema. Local haemorrhage was significantly reduced in mice pre-treated with capsaicin or guanethidine or submitted to a surgical section of sciatic and saphenous nerves. In these animals, oedema was not affected. Groups treated with methysergide or morphine showed both haemorrhage and oedema significantly reduced. Indomethacin or dexamethasone pre-treatments significantly reduced the oedema, but not the haemorrhage. Moreover, in animals treated with promethazine or mepyramine, oedema and haemorrhage were not affected. These data suggest that local haemorrhage induced by Bothrops jararaca venom is partially controlled by serotonin and neurohumoral mediators. Furthermore, results indicate that haemorrhage and oedema are mediated by different pharmacological systems.  (+info)

Rapid purification of serine proteinases from Bothrops alternatus and Bothrops moojeni venomsRapid purification of serine proteinases from Bothrops alternatus and Bothrops moojeni venoms
Envenomation by Bothrops species results, among other symptoms, in hemostatic disturbances. These changes can be ascribed to the presence of enzymes, primarily serine proteinases some of which are structurally similar to thrombin and specifically cleave fibrinogen releasing fibrinopeptides. A rapid, three-step, chromatographic procedure was developed to routinely purify serine proteinases from the venoms of Bothrops alternatus and Bothrops moojeni. The serine proteinase from B. alternatus displays an apparent molecular mass of similar to 32 kDa whereas the two closely related serine proteinases from B. moojeni display apparent molecular masses of similar to 32 kDa and similar to 35 kDa in SDS-PAGE gels. The partial sequences indicated that these enzymes share high identity with serine proteinases from the venoms of other Bothrops species. These proteins coagulate plasma and possess fibrinogenolytic activity but lack fibrinolytic activity. (C) 2013 Elsevier Ltd. All rights reserved.. ...

The ability of pre-existing antibodies to neutralize locally-acting toxins of Bothrops asper snake venom was investigated. Hemorrhage, myonecrosis, and edema were markedly reduced in actively immunized mice, although none of these effects was completely abolished. In mice passively immunized with equine antivenom, hemorrhage was prevented completely, while myonecrosis and edema were partially reduced. Pre-existing antibodies did not modify the early stage ( , 3 hr) of venom-induced edema, but significantly accelerated the normalization of this effect within 24 hr. Passive administration of antivenom either 5 or 120 min before venom injection gave similar results, suggesting that the presence of antibodies in the intravascular compartment may fully neutralize locally acting toxins, in this experimental animal model. Overall, the homologous or heterologous origin of antibodies was not a significant factor influencing their in uit,o neutralizing efficiency against local venom effects. Antibody ...

Acervo Digital: Molecular cloning and biochemical characterization of a myotoxin inhibitor from Bothrops alternatus snake plasmaAcervo Digital: Molecular cloning and biochemical characterization of a myotoxin inhibitor from Bothrops alternatus snake plasma
Phospholipases A(2) (PLA(2)s) are important components of Bothrops snake venoms, that can induce several effects on envenomations such as myotoxicity, inhibition or induction of platelet aggregation and edema. It is known that venomous and non-venomous snakes present PLA(2) inhibitory proteins (PLIs) in their blood plasma. An inhibitory protein that neutralizes the enzymatic and toxic activities of several PLA2s from Bothrops venoms was isolated from Bothrops alternatus snake plasma by affinity chromatography using the immobilized myotoxin BthTX-I on CNBr-activated Sepharose. Biochemical characterization of this inhibitory protein, denominated alpha BaltMIP, showed it to be a glycoprotein with Mr of similar to 24,000 for the monomeric subunit. CD spectra of the PLA(2)/inhibitor complexes are considerably different from those corresponding to the individual proteins and data deconvolution suggests that the complexes had a relative gain of helical structure elements in comparison to the individual ...

Angiogenesis and wound repair are mediated by several growth factors that are strictly released. Alternagin-C (ALT-C), a disintegrin-like protein from the venom of Bothrops alternatus induces in vivo angiogenesis as well as the cyclic peptide derived from its primary structure, with the ECD motif (ALT-C PEP). This study investigated the effects of ALT-C and ALT-C PEP on angiogenesis and expression of growth factors in a model of wounded rat skin. The rats were anaesthetized; one cutaneous excision (4 mm diameter) was made on the back of each animal, close to the cervical area. Animals were then divided into 7 groups (five rats/group): control (treated with vehicle); locally treated with 10, 60 and 100 ng ALT-C or 10, 20 and 100 ng ALT-C PEP ALT-C PEP for 1, 3, 5 or 7 consecutive days.

The local and systemic pathophysiological alterations induced by BjussuSP-I, a thrombin-like serine proteinase from the venom of the snake Bothrops jararacussu, were assessed in mice. BjussuSP-I induced a mild edema but no local myonecrosis or hemorrhage. It did not induce any microvascular alteration in the cremaster muscle. Intramuscular injection of BjussuSP-I promoted an increase in the expression of proMMP-9, but it did not induce the activation of proMMP-2 or proMMP-9 synthesized in muscle tissue injected with a myotoxic phospholipase A2 homolog. BjussuSP-I induced defibrin(ogen)ation upon intravenous and intramuscular injections, with reduction in plasma fibrinogen concentration and increments in the levels of fibrin degradation products and D-dimer. When compared with animals having normal coagulation, mice defibrin(ogen)ated by BjussuSP-I developed a slightly larger hemorrhagic lesion in the skin when injected with metalloproteinase BaP1. Intravenous injection of sublethal doses of ...

Abstract in English:. Bothrops jararacussu venom and its major toxin bothropstoxin-I (BthTX-I) possess myotoxic and neurotoxic properties. The efficacy of a rabbit antivenom raised against B. jararacussu venom in the neutralization of physiological, biochemical, and morphological changes induced by the venom and its major toxin BthTX-I was studied in mouse isolated phrenic nerve-diaphragm (PND) and extensor digitorum longus (EDL) preparations. The times required for 50% neuromuscular blockade in PND and EDL preparations for venom were 70+11.5 (S.E.M., n=5) min and 58+8 (n=16) (50 mu g/mL), and for BthTX-I 31+6 (n=3) min and 30+3 (n=5) min (20 mu g/mL), respectively. After 120 min incubation, creatine kinase (CK) concentrations in solution containing the EDL preparations were 3464+346 U/L after exposure to venom (50 mu g/mL, n=5) and 3422+135 U/L to BthTX-I (20mu g/mL, n=4), respectively.

Isolation of a myotoxin from Bothrops asper venom: Partial characterization and action on skeletal muscleIsolation of a myotoxin from Bothrops asper venom: Partial characterization and action on skeletal muscle
A myotoxic phospholipase has been isolated from Bothrops asper venom by ion-exchange chromatography on CM-Sephadex followed by gel filtration on Sephadex G-75. The toxin is a basic polypeptide with an estimated molecular weight of 10,700. It has both phospholipase A and indirect hemolytic activities, but is devoid of proteolytic, direct hemolytic and hemorrhagic effects. When injected i.m. into mice the toxin induces a rapid increase in plasma creatine kinase levels and a series of degenerative events in skeletal muscle which lead to myonecrosis. The toxin induces an increase in intracellular calcium levels and is able to hydrolyze muscle phospholipids in vivo. Pretreatment with the calcium antagonist verapamil failed to prevent the myotoxic activity. It is proposed that B. asper myotoxin causes cell injury by disrupting the integrity of skeletal muscle plasma membrane and that myotoxicity is at least partially due to the phospholipase A activity of the toxin ...

Envenenamento experimental por Bothrops jararaca em camundongos prenhes: Eficácia do soro antibotrópicoEnvenenamento experimental por Bothrops jararaca em camundongos prenhes: Eficácia do soro antibotrópico
Introdução: Neste estudo foi avaliada a eficácia do soro antibotrópico (SAB) em camundongos prenhes submetidos ao veneno bruto da serpente Bothrops jararaca (Bj). Para tanto, o veneno foi administrado em camundongos no 7,5º dia de prenhez (dp), data importante, onde, de acordo com a literatura, alterações teratogênicas podem ocorrer.

Bothrops asper - WikipediaBothrops asper - Wikipedia
Common names: fer-de-lance, terciopelo, Bothrops asper is a highly venomous pit viper species ranging from southern Mexico to northern South America. Sometimes referred to as the ultimate pit viper, these snakes are found in a wide range of lowland habitats, often near human habitations. Its proximity to human habitations and temperament are likely the reasons why it is considered more dangerous to humans than others. This species is the main cause of snakebite incidents within its range. No subspecies are currently recognized. The generic name, Bothrops, comes from the Greek words bothros and ops, which mean pit and face (or eye), respectively. This is a reference to these snakes highly sensitive heat-detecting pit organs. The specific epithet, asper, which is a Latin word meaning rough or harsh, may allude to the species keeled dorsal scales. Some of the common names applied to this snake are terciopelo, fer-de-lance, Mapepire balsain (Trinidad), barba amarilla (Guatemala, ...

Bothrops jararacussu snake venom produces myonecrosis and nerve degeneration. In this work, we investigated whether nerve lesions or impaired muscle regeneration contributed to the permanent loss of muscle mass, a long-term sequela of envenoming. The right soleus muscle of adult male mice was injected with B. jararacussu venom (80 mug) while the left muscle received only saline (control). The mice were killed after 2 and 3 months and the muscles were removed and processed for examination by transmission electron microscopy and light microscopy. The nerve fibers, Schwann cells and neuromuscular junctions had regenerated in venom-treated muscle. The total number of muscle fibers was significantly lower (p , 0.05) than in the control (617 +/- 48 versus 1235 +/- 97, respectively; mean +/- SEM, n = 10). These results show that the loss of muscle mass was most likely related to a decrease in the ability of the muscle to regenerate rather than to nerve lesions. (C) 2004 Elsevier Ltd.

Quantitation by enzyme-immunoassay of antibodies against Bothrops myotoxins in four commercially-available antivenomsQuantitation by enzyme-immunoassay of antibodies against Bothrops myotoxins in four commercially-available antivenoms
An enzyme-immunoassay (EIA) for the quantitation of antibodies against myotoxins present in the venoms of Bothrops asper (Costa Rica), B. atrox (Colombia) and B. moojeni (Brazil), was developed. This EIA was utilized for the evaluation of four antivenoms produced in Mexico (Laboratorios Myn; MYN), Costa Rica (Instituto Clodomiro Picado; ICP), Colombia (Instituto Nacional de Salud; INS) and Brazil (Instituto Butantan; IB). Antivenoms ICP, IB and INS showed a higher titer of antibodies against the three myotoxins tested, with only slight differences between them, depending on the antigen utilized. In contrast, MYN antivenom had very low levels of antibodies to the three myotoxins. Seventeen batches of ICP antivenom were analyzed by EIA, using B. asper myotoxin II as antigen. Although all batches had high anti-myotoxin titers, these varied significantly. Batches produced after 1988 had, in general, higher titers than older (1986-1987) ones. Antivenom stored for one year at 37 degrees C had a ...

Numerous plants are used as snakebite antidotes in Brazilian folk medicine, including Casearia sylvestris Swartz, popularly known as guaçatonga. In this study, we examined the action of a hydroalcoholic extract from C. sylvestris on the neuromuscular blockade caused by bothropstoxin-I (BthTX-I), a myotoxin from Bothrops jararacussu venom, in mouse isolated phrenic nerve-diaphragm (PND) preparations. Aqueous (8 and 12 mg/ml, n=4 and 5, respectively) and hydroalcoholic (12 mg/ml, n=12) extracts of the leaves of C. sylvestris caused facilitation in PND preparations followed by partial neuromuscular blockade. BthTX-I (20 µg/ml, n=4) caused 50% paralysis after 65±15 min (mean ± S.E.M). Preincubation (30 min at 37° C) of BthTX-I (20 µg/ml, n=4) with a ...

Toxicon 31, 1237-1247, 1993.-The effects of Bothrops insularis venom were examined in vivo in mice and chicks and in vitro using the mouse phrenic nerve diaphragm and chick biventer cervicis muscle preparations. Incubation of the indirectly or directly stimulated mouse preparation with B. insularis venom (20-80 μg/ml) produced an initial increase in twitch tension followed by irreversible blockade. With direct stimulation in the presence of d-tubocurarine, no increase in twitch tension was observed prior to the onset of blockade. A venom-induced effect on presynaptic activity was suggested by the marked increase in the frequency of the mepps recorded in vitro 5-15 min after venom addition. A direct muscular effect was shown by the dose- and time-dependent reduction in the resting membrane potential of the diaphragm. ...

Myotoxic phospholipases A2 (PLA2) are responsible for many clinical manifestations in envenomation by Bothrops snakes. A new myotoxic acidic Asp49 PLA2 (BaCol PLA2) was isolated from Colombian Bothrops asper venom using reverse-phase high performance liquid chromatography (RP-HPLC). BaCol PLA2 had a molecular mass of 14,180.69 Da (by mass spectrometry) and an isoelectric point of 4.4. The complete amino acid sequence was obtained by cDNA cloning (GenBank accession No. MF319968) and revealed a mature product of 124 amino acids with Asp at position 49. BaCol PLA2 showed structural homology with other acidic PLA2 isolated from Bothrops venoms, including a non-myotoxic PLA2 from Costa Rican B. asper. In vitro studies showed cell membrane damage without exposure of phosphatidylserine, an early apoptosis hallmark. BaCol PLA2 had high indirect hemolytic activity and moderate anticoagulant action. In mice, BaCol PLA2 caused marked edema and myotoxicity, the latter seen as an increase in plasma creatine kinase

Loss of venom from the venom gland after biting or manual extraction leads to morphological changes in venom secreting cells and the start of a cycle of production of new venom. We have previously shown that stimulation of both (alpha- and beta-adrenoceptors in the secretory cells of the venom gland is essential for the onset of the venom production cycle in Bothrops jararaca. We investigated the signaling pathway by which the alpha(1)-adrenoceptor initiates the venom production cycle. Our results show that the alpha(1)-adrenoceptor subtype is present in venom gland of the snake. in quiescent cells, stimulation of alpha(1)-adrenoceptor with phenylephrine increased the total inositol phosphate concentration, and this effect was blocked by the phospholipase C inhibitor U73122. Phenylephrine mobilized Ca(2+) from thapsigargin-sensitive stores and increased protein kinase C activity. in addition, alpha(1)-adrenoceptor stimulation increased the activity of ERK 1/2, partially via protein kinase C. ...

We report the detailed molecular characterization of two PLA2s, Lys49 and Asp49 isolated from Bothrops leucurus venom, and examined their effects against Dengue virus (DENV). The Bl-PLA2s, named BlK-PLA2 and BlD-PLA2, are composed of 121 and 122 amino acids determined by automated sequencing of the native proteins and peptides produced by digestion with trypsin. They contain fourteen cysteines with pIs of 9.05 and 8.18 for BlK- and BlD-PLA2s, and show a high degree of sequence similarity to homologous snake venom PLA2s, but may display different biological effects. Molecular masses of 13,689.220 (Lys49) and 13,978.386 (Asp49) were determined by mass spectrometry. DENV causes a prevalent arboviral disease in humans, and no clinically approved antiviral therapy is currently available to treat DENV infections. The maximum non-toxic concentration of the proteins to LLC-MK2 cells determined by MTT assay was 40 µg/mL for Bl-PLA2s (pool) and 20 µg/mL for each isoform. Antiviral effects of Bl-PLA2s were

Angiotensin converting enzyme inhibition: from viper to patient | HeartAngiotensin converting enzyme inhibition: from viper to patient | Heart
The story of angiotensin converting enzyme (ACE) inhibitors started approximately 50 years ago, when it was discovered that human plasma incubated with the venom of the Brazilian viper,Bothrops Jararaca, generated a hypotensive compound. This discovery quickly led to the characterisation of the active principle of the venom by Fereira and Greene as a family of peptides, which were named bradykinin potentiating factors as they selectively improved the biological effects of bradykinin. The observation was then made by Vane that these peptides could also block the conversion of angiotensin I into angiotensin II via the angiotensin converting enzyme. The active peptides were isolated and teprotide became the first ACE inhibitor to be evaluated clinically. The search for an orally active compound that was sufficiently potent to be developed as an antihypertensive drug resulted in the design and development of captopril, which entered first phase clinical studies in 1977.. ACE has a key role in two ...

Sérgio Henrique Ferreira (October 4, 1934 - July 17, 2016) was a Brazilian physician and pharmacologist noted for the discovery of the bradykinin potentiating factor, which led to new and widely used anti-hypertension drugs - the ACE inhibitors. Ferreira received his M.D. from the Faculty of Medicine of Ribeirão Preto of the University of São Paulo (USP) and soon became staff member of the same school, where he is a member of the Department of Pharmacology. His research training in pharmacology initiated in this Department with Prof. Maurício Rocha e Silva, the discoverer of bradykinin. While working on this subject, he discovered a family of peptides present in the venom of a Brazilian snake, Bothrops jararaca, which inhibited kininase activity and strongly potentiated the effects of bradykinin in vivo and in vitro. This factor was named bradykinin potentiating factor, BPF. In 1968, with the collaboration of Dr. Lewis Joel Greene, from the Brookhaven National Laboratory, U.S., he isolated ...

L-amino acid oxidases isolated from snake venoms (SV-LAAOs) are enzymes that have great therapeutic potential and are currently being investigated as tools for developing new strategies to treat various diseases, including cancer and bacterial infections. The main objective of this study was to make a brief evaluation of the enzymatic stability of two Bothrops LAAOs, one isolated from Bothrops jararacussu (BjussuLAAO-II) and the other from Bothrops moojeni (BmooLAAO-I) venoms. The enzymatic activity and stability of both LAAOs were evaluated by microplate colorimetric assays, for which BjussuLAAO-II and BmooLAAO-I were incubated with different L-amino acid substrates, in the presence of different ions, and at different pH ranges and temperatures. BjussuLAAO-II and BmooLAAO-I demonstrated higher affinity for hydrophobic amino acids, such as Phe and Leu. The two enzymes showed high enzymatic activity in a wide temperature range, from 25 to 75 °C, and presented optimum pH around 7.0. Additionally, Zn2+,

Introduction. Bothrops pirajai snake is an endemic species from the South region of Bahia state, Brazil, and it belongs nowadays to a national list of Brazilian fauna species threatened of extinction (Martins & Molina, 2008). Its venom is rich in proteins such as phospholipases A2, desintegrins, metalloproteases, serinoproteases, L-amino acid oxidases and others (Rodrigues et al., 2009). L-amino acid oxidases (LAAO, EC 1.4.3.2) are enantioselective flavoenzymes catalyzing the oxidative deamination of a wide range of L-amino acids (Stábeli et al., 2007). During the reductive half-reaction, the amino acid substrate is oxidized to the imino acid with concomitant reduction of the flavin adenine dinucleotide (FAD) cofactor. The imino acid product of oxidation undergoes a non-enzymatic hydrolysis to give the respective α-keto acid and ammonia. An oxidative half-reaction completes the catalytic cycle re-oxidizing the FAD with molecular oxygen and producing hydrogen peroxide (Moustafa et al., ...

THE COAGULATION OF BLOOD BY SNAKE VENOMS AND ITS PHYSIOLOGIC SIGNIFICANCE | JEMTHE COAGULATION OF BLOOD BY SNAKE VENOMS AND ITS PHYSIOLOGIC SIGNIFICANCE | JEM
Nine of the 17 venoms here tested were found capable of coagulating citrated blood or plasma. As has been believed by most workers in the field, 7 of these 9 coagulant venoms convert fibrinogen to an insoluble modification resembling fibrin (Bothrops atrox, Bothrops jararaca, Bothrops nummifera, Crotalus adamanteus, Crotalus horridus, Crotalus terrificus basiliscus, Crotalus terrificus terrificus). The optimum pH for this coagulation was determined for 3 of these, and was found in each case to be approximately pH 6.5, the same as that for the action of thrombin on fibrinogen. Unlike thrombin, however, the fibrinogen-coagulating activity of the venoms was unaffected by the antithrombin elaborated in the course of anaphylactic shock.. In addition to coagulating fibrinogen directly, 3 of these venoms (Bothrops atrox, Bothrops jararaca, and to a less extent, Crotalus terrificus basiliscus) acted on prothrombin to convert it to thrombin, without the necessary intervention of either calcium or ...

Bothropstoxin-I (BthTx-I) is a Lys49-phospholipase A2 from the venom of Bothrops jararacussu which demonstrates both myotoxic and Ca2+-independent membrane-damaging activities. The structural determinants of these activities are poorly defined, therefore site-directed mutagenesis has been used to substitute all cationic and aromatic residues between positions 115 and 129 in the C-terminal loop region of the protein. Substitution of lysine and arginine residues with alanine in the region 117-122 resulted in a significant reduction of myotoxic activity of the recombinant BthTx-I. With the exception of Lys122, these same substitutions did not significantly alter the Ca2+-independent membrane-damaging activity. In contrast, substitution of the positively-charged residues at positions 115, 116 and 122 resulted in reduced Ca2+-independent membrane-damaging activity but, with the exception of Lys122, had no effect on myotoxicity. These results indicate that the two activities are independent and are ...

Snake venomics of Bothrops punctatus, a semiarboreal pitviper species from Antioquia, Colombia [PeerJ]Snake venomics of Bothrops punctatus, a semiarboreal pitviper species from Antioquia, Colombia [PeerJ]
Bothrops punctatus is an endangered, semi-arboreal pitviper species distributed in Panamá, Colombia, and Ecuador, whose venom is poorly characterized. In the present work, the protein composition of this venom was profiled using the snake venomics analytical strategy. Decomplexation of the crude venom by RP-HPLC and SDS-PAGE, followed by tandem mass spectrometry of tryptic digests, showed that it consists of proteins assigned to at least nine snake toxin families. Metalloproteinases are predominant in this secretion (41.5% of the total proteins), followed by C-type lectin/lectin-like proteins (16.7%), bradykinin-potentiating peptides (10.7%), phospholipases A2 (93%), serine proteinases (5.4%), disintegrins (38%), L-amino acid oxidases (3.1%), vascular endothelial growth factors (17%), and cysteine-rich secretory proteins (1.2%). Altogether, 6.6% of the proteins were not identified. In vitro, the venom exhibited proteolytic, phospholipase A2, and L-amino acid oxidase activities, as well as angiotensin

My laboratory, in collaboration with my colleague Dr. Jon Bjarnason, was one of the first to identify and characterize the metalloproteinases present in numerous snake venoms. These Snake Venom Metalloproteinases; SVMPs are responsible for many of the pathologies associated with snake envenoming. Our research has elucidated the structures of these toxins and identified the biochemical and cellular mechanisms by which the toxins function to give rise to their noted pathologies. Specifically my research interests have been centered on metalloproteinases and extracellular matrix and the processes they regulate in normal and pathological circumstances. Our recent focus has expanded to include the interaction of host and tumor in carcinogenesis and metastasis and the role of stromal microenvironment, inflammation in cancer metastasis and invasion. We are also carrying out research on the discovery and validation of biomarkers associated with normal and chronic wound healing. Our longstanding interest ...
