In the case of the paper, this looked at measures for a particular type of snakebite , which included examining the effects of applying firm crepe bandages on monkeys.

Moreover, Phα1β and its recombinant version were able to reduce the inflammatory phase of the formalin-induced nociceptive behavior in rats, to decrease neuropathic pain caused by chronic constriction injury of sciatic nerve in rats, and to reduce the hyperalgesia caused by melanoma cancer model in mice Rigo et al.

nigriventer venom became attractive because of its induced-priapism effect. Interestingly, a minimum dose of 0. PnPP is a promising candidate for erectile dysfunction treatment in patients that do not respond to the usual therapies Silva et al.

Biozeus Biopharmaceutical S. A performed pilot tests with the topical peptide renamed BZ on healthy human beings and has been performing a pilot test with voluntary men with erectile dysfunction associated to hypertension or diabetes.

The regulatory toxicological preclinical tests have already started. org , their therapeutic use are limited due to their susceptibility to proteolysis. Tetrodotoxin TTX , a guanidinium neurotoxin with high affinity for voltage-gated sodium Na v channels, had traditionally been known for many years as the main toxin from Tetraodontidae pufferfish Lago et al.

However, the toxin was present not only in other marine animals such as octopuses, gobies and sea stars, but also in phylogenetically unrelated terrestrial and aquatic organisms, including a dinoflagellate Alexandrium tamarense , red calcareous algae, arthropods, echinoderms, molluscs, worms, newts, frogs, and bacteria Actinomyces , Aeromonas , Alteromonas , Bacillus and Pseudomonas Lago et al.

TTX has been used for the development of analgesic and anesthetic drugs Assuncao et al. The salivary secretion from different animals, such as bats, leeches, lizards, shrews and ticks are considered important sources of biologically active compounds.

Other animals, such as caterpillars, have biologically active compounds in their bristles. Many of these compounds are still underexploited, lacking information on their chemical structure, physiological role and therapeutic application.

Thus, the study of these compounds increases the chances of discovering new compounds with great pharmaceutical potential. The subsections Bats to Ticks will address some potential therapeutic molecules found in the saliva or bristles of these animals. This fibrin-dependent plasminogen activator is composed of amino acids with high fibrin specificity, long half-life, low bleeding tendency, nonactivation by β-amyloid and lack of neurotoxicity Medcalf, ; Shi et al.

A phase III randomized study in participants with acute ischemic stroke was completed in Currently, there is no drug based on desmoteplase available for commercialization. Caterpillars from different South American countries, such as Venezuela, Brazil, French Guyana, Peru, Paraguay, Argentina and Colombia, are responsible for a severe bleeding syndrome in humans who touch their bristles Arocha-Pinango and Guerrero, Lonomia obliqua is the main species of caterpillar found in Southern Brazil and its venom is comprised of molecules with antiviral, procoagulant, fibrinolytic and wound healing activities Veiga et al.

Their toxic compounds are found in the bristle extract, hemolymph, cryosecretion a crude venomous fluid ejected by the whole secretory tegument of caterpillars, stored at °C for 24 h and tegument extract Pinto et al. Some compounds with potential therapeutic applications were identified in Lonomia sp, e.

Lonofibrase , protease inhibitors, serpins, lipocalins, and lectins Veiga et al. Currently, there are three clinical studies on caterpillars recorded at the Clinical Trials website US National Library of Medicine, However, these studies are related to their use as a source of protein in the diet and none of them involves the genus Lonomia.

Two phase II randomized studies involving leech therapy in NCT and 60 participants NCT with knee osteoarthritis were completed in and , respectively. Additional information on FDA-approved hirudin analogues from H.

medicinalis leech saliva and hirudotherapy was reported in section Achievements With Animal Toxin-Based Molecules. Exenatide is the synthetic version of the native peptide exendin-4 isolated from the saliva of Gila monster lizard H.

suspectum Eng et al. According to the Clinical Trials website, there are more than clinical studies about exenatide. So far, there are completed studies, 12 terminated, 25 whose status has not changed for 2 years, 47 recruiting volunteers, 11 that are not yet recruiting, and three enrolled by invitation.

For an extensive review regarding clinical trials involving this drug, please see Odegard and Desantis, ; Bhavsar et al.

Additional information on exenatide was described in section Achievements With Animal Toxin-Based Molecules. SOR-C13 is a synthetic selective peptide inhibitor of Transient Receptor Potential Vanilloid 6 TRPV6 calcium oncochannel Pennington et al.

It is comprised of 13 amino acids derived from the C-terminal region of the paralytic peptide soricidin UniProtKB—P0C2P6 , from the submaxillary and sublingual salivary glands of the Northern Short-tailed shrew Blarina brevicauda Bowen et al.

It inhibits the activation of nuclear factor of activated T-cell NFAT transcription complex, and induces apoptosis in TRPV6-overexpressing cells NIH National Cancer Institute, A phase I of study NCT in 23 advanced cancer patients with TRPV6 channel overexpression was completed in and a phase I study NCT started recruiting patients with advanced refractory solid tumors in There are several studies addressing the importance of tick saliva components.

The use of evasins in the treatment of heart diseases, such as myocarditis Singh et al. However, although tick saliva contains many components with therapeutic and biotechnological potentials, there are neither clinical studies involving the use of substances isolated from tick saliva nor drugs available for therapeutic purposes.

The clinical studies currently registered on the Clinical Trial website in respect to ticks are related to the development of vaccines against ticks or the use of different antibiotics in Lyme disease. Animal poisons and venoms are comprised of a cocktail of bioactive components with a gamut of different activities.

Company pipelines worldwide are expanding the number of peptide-based products currently in development mainly because of the diversity of their application and activity.

However, industrial production of toxin-related drugs from natural sources is quite challenging, laborious and presents restricted yield Boldrini-França et al. To overcome these limitations, the main options are the chemical synthesis of peptides and the production of biopharmaceuticals via heterologous expression using biotechnological tools.

Recent data reinforces the advances in transcriptomics, proteomics and heterologous expression techniques, which allowed the characterization and potential production of low abundant active venom components, presenting low or high molecular mass Boldrini-França et al.

The industry has focused on heterologous expression systems as an interesting alternative for manufacturing biopharmaceuticals of high molecular mass Merlin et al. Recombinant protein production processes require extensive design and regulatory control before therapeutic products become commercially available.

Regarding heterologous expression, the accurate cysteine bond formation and the proper incorporation of post-translational modifications remain a challenge, and new technologies to assess and mitigate immunogenicity risk of engineered proteins are becoming more common.

Therefore, a special attempt should be made to ensure that the recombinant protein presents comparable three-dimensional folding and consistent pharmacological properties when compared to its corresponding native form.

Native chemoselective reaction has been employed in the production of animal toxins with potential therapeutic application, such as mambalgin-2, a amino acid analgesic peptide from three-finger toxins family, from Dendroaspis polylepis polylepis venom Diochot et al. This approach allows the synthesis of large proteins, since it is based in the production of different unprotected linear peptide fragments, which are condensed in solution via chemoselective reactions to originate the entire polypeptide Kent et al.

Studies to improve the protecting groups, resins, linkers, and activation and coupling reagents may enable the manufacture of larger peptides and even small proteins for therapeutic applications.

However, the development of cheaper reagents and methods for the synthesis and purification of peptides are necessary. Concerning the limitations of peptides in terms of their biopharmaceutical properties, designed approaches that will find molecules with intrinsically more favorable properties will need to be devised.

As mentioned earlier in section Achievements With Animal Toxin-Based Molecules , the drug design of captopril made oral administration possible.

Additionally, designed cationicity-enhanced analogues of natural antimicrobial peptides have exhibited higher potency and spectra of antimicrobial activity Luna-Ramirez et al.

Achievements towards successful oral delivery of proteins and peptides by protecting them against degradation and increasing their absorption remain as an active area of research. Regarding toxin-based formulations, intranasal inoculation of hyaluronidase from T.

serrulatus venom induced mononuclear increase in the bronchoalveolar space and became a promising tool for the treatment of pulmonary fibrosis Bitencourt et al. Some approaches to improve biopharmaceuticals delivery, such as alternative delivery routes, PEGylation and conjugation to nano carriers, represent a relevant step towards targeted delivery of toxin-based drugs.

It is sobering to realize how little alternative delivery routes and bioconjugation strategies have been exploited to deliver toxin-based drugs, suggesting that studies on routes of distribution, delivery vehicles, cargo molecules, and targeting strategies are fruitful fields for future research.

Collinein-1, a thrombin-like serine protease from C. collilineatus , was successfully modified by site-specific PEGylation with maleimide-mPEG of 5 kDa and exhibited higher catalytic efficiency and affinity for the substrate than the native form da-Silva-Freitas et al.

The PEGylated peptide HsTX1[R14A] from Heterometrus spinnifer scorpion venom showed higher plasma circulating half-life in rodents compared to the native peptide, which resulted in sustained efficacy in rodent models of multiple sclerosis and rheumatoid arthritis Tanner et al.

In the drug development process, formulation patents using advanced drug release systems extend the market exclusivity of drugs, because of the high technical barrier to be overcome by generic manufacturers after the expiration of patents.

Focusing on competitiveness, pharmaceutical companies have established strategic partnerships with leading academic institutions that have deep scientific expertise in novel concepts in the main areas of biology or chemistry. Some reports have shown the antitumor potential, among other applications, of animal venoms or their toxins conjugated with a wide variety of nanomaterials, such as silica, gold, chitosan, poly D,L-Lactide -based, and supermagnetic iron oxide nanoparticles Badr et al.

Studies on cell penetrating peptides CPPs have open unprecedented possibilities for vector applications in several fields, such as basic research, therapeutics, technology, and medical imaging. serrulatus venom, showed to be a potential intranuclear delivery tool to target cancerous cells de Oliveira-Mendes et al.

WaTx, a cell-penetrating toxin from the Australian black rock scorpion U. Another field in ever-growing demand is the cosmeceutical industry, especially in Asia, where Korea is at the forefront of cosmeceutical development.

Efficacy and safety studies on these products in humans are on high demand Juhász et al. Animal poisons and venoms are rich sources of molecules with a wide range of applications. However, to make the use of these molecules feasible, extensive preclinical trials are necessary, with some applications also requiring clinical trials Figure 2.

Figure 2 Animal poisons and venoms as sources of candidate molecules for wide-ranging applications, after extensive characterization during preclinical and clinical trials.

Although the research in the field of toxinology tends to be quite challenging and time-consuming, the high selectivity of animal toxins for their targets turns them into promising leads for the development of effective therapeutic drugs. Studies on new engineered molecules with reduced side effects can be reached by untangling the interaction of venom peptides with their target.

Therefore, we are still at a beginning phase in comprehending the complexity of animal venoms and poisons. While very few species have been extensively studied, we still have thousands of unexploited organisms, especially marine ones.

Novel methods to produce and deliver biopharmaceuticals are expected to be developed in the near future. With that in mind, we can get a glimpse of how much work on toxinology and drug discovery is yet to come in the next years.

This study aimed defoxification evaluate the clinical therapeutic efficacy of anti-snake venom Snake venom detoxification methods blockade vdnom treating local Snake venom detoxification methods necrosis caused methodx Chinese cobra Naja Liver detoxification methods bites. The experimental setoxification received Snake venom detoxification methods as Snke as anti-snake venom serum blocking treatment, genom regular treatment plus chymotrypsin blocking therapy was given detoxirication the control group. The necrotic volumes around snake wounds in these groups were detected on the first, third and seventh days. On the third day of treatment, some local tissues in the wounds were randomly selected for pathological biopsy, and the necrosis volume of the local tissue was observed. Furthermore, the amount of time required for wound healing was recorded. Moreover, the pathological biopsies taken from the control group showed nuclear pyknosis, fragmentation, sparse nuclear density, and blurred edges, and the degree of necrosis was much higher than that of the experimental group. Anti-snake venom blocking therapy is a new and improved therapy with good clinical effect on local tissue necrosis caused by Chinese cobra bites; moreover, it is superior to conventional chymotrypsin blocking therapy in the treatment of cobra bites.

Snake venom detoxification methods -

When a compound is irradiated in a solution, the indirect effect joins the direct 9. Since water is the most abundant constituent of biological material, it is important to consider the species produced by excitation and ionization of water itself, and the reaction of these species with the target molecules of biological importance.

This indirect effect results from the reactions among the studied molecules and the products of radiation interaction with water or other solvents.

Highly reactive compounds, the so-called free radicals, which are formed undergo many reactions among themselves, with the dissolved gas, and with other molecules in the solution. With water, the excitation is less important than ionization which is followed within picoseconds by the formation of free hydroxyl radicals and hydrated electrons 2,4, With these results, it would be possible to use of ionizing radiation to change those protein molecules in order to improve some of their properties according to the necessity.

On the other hand, it is recognized that venoms in general are poorly immunogenic, yet fairly toxic This causes problems because serotherapy is the treatment of choice in snakebite envenomations, and horse antivenom availability is dependent upon immunogenicity.

KEY WORDS: Detoxification of snake venom, ionizing radiation, gamma rays. To improve antivenom production and extend the useful life of immunized horses effort has been devoted to decrease chronic venom toxicity 5,6,7,8,11,12,17,18, 20, Thus, once snake venoms are rich in proteins, Lauhatirananda et al.

They reported that irradiated venoms presented low toxicity, and that when the samples were in a dry state, the suitable irradiation dose to attenuate toxicity was higher than that used to samples in aqueous form.

In addition, Kankonkar et al. Few years later, Herrera et al. Murata et al. Following these studies Guarnieri 10 , used gamma rays to detoxify Bothrops jararaca venom. As found to Crotalus durissus terrificus venom, 2, Gy was the necessary dose to get the detoxification with maintenance of immunological properties observed through results of immunodiffusion, immunoblotting, immunoprecipitation, immunization of mice and rabbits and neutralization tests.

In addition, it was observed through proteolytic, hemorrhagic, coagulant and edema-forming activities, gel filtration and electrophoresis some conformational and structural alterations, protein aggregate formation and attenuation of tested activities. Furthermore, the animals immunized with irradiated venom presented no cutaneous lesion which is very common when Bothrops jararaca venom is injected.

More recently, Nascimento manuscript submitted to Toxicon has worked with crotoxin, main toxin of Crotalus durissus terrificus venom, in order to study the effects of gamma rays on purified toxin. Irradiation of crotoxin resulted in an aggregation and a generation of lower molecular weight breakdown products.

The high molecular weight aggregates were isolated by gel filtration and its immunological, biological and biochemical properties were analyzed. The aggregates presented no toxicity, no phospholipase activity and no ability to promote creatine kinase CK release into muscle tissue.

On the other hand, these aggregates were highly antigenic and were able to induce antibody formation in mice which cross-reacted with non irradiated crotoxin. In addition, mice immunized with aggregated immunogen survived a challenge of 15 LD50 of non irradiated crotoxin.

When biodistribution experiments were developed in mice, using labeled crotoxin with I, it could be observed that irradiated crotoxin was poorly retained in tested organs liver, muscle, spleen, kidneys, lungs, heart and brain , mainly in kidneys where no retention was observed.

Nascimento suggests that this results indicate ionizing radiation as a good tool in the detoxification process, highlighting out the aggregates as the ideal immunogen to be used during the immunization process to get snake antivenom without damage to the serum-productor animals.

Considering these promising results, other snake venoms have been studied in our laboratory such as Bothrops jararacussu, Lachesis muta venom and some experiments also were made with bee venom with good results of attenuation of toxicity when submitted to the effects of gamma rays.

Snakebites from highly venomous species can be fatal [ 4 4. Alirol E, Sharma SK, Bawaskar HS, Kuch U, Chappuis F. Snake bite in South Asia: a review. Gutierrez JM. Snakebite envenoming from an Ecohealth perspective.

Toxicon X. It is often difficult to find the appropriate antivenom for optimal clinical management, due to the misidentification of the snake species. Previously, there was a lack of careful studies investigating the protein profiles of the serum from snakebite patients.

Thus, we used label-free protein expression profiling to identify potential protein biomarkers in the serum of patients bitten by four different snake species. We found that one candidate compound, hydrogen peroxide, was highly associated with many proteins in the interaction network of proteins and drug compounds.

The label-free method is an effective technique for the simultaneous identification and quantification of thousands of proteins, providing potential biomarkers in a highly focused pool [ 29 Higgs RE, Knierman MD, Gelfanova V, Butler JP, Hale JE. Label-free LC-MS method for the identification of biomarkers.

Due to interpersonal variability, the expression proteins were qualified to satisfy the condition of at least two non-null intensities in replicates of each subgroup.

This resulted in unique proteins that showed high reproducibility between snakebite patients and the healthy control group. The distinct reduction in the number of shared proteins may result from biased estimates in the clinic in identifying similar snakes [ 31 Wuster W, Allum CS, Bjargardottir IB, Bailey KL, Dawson KJ, Guenioui J, et al.

Do aposematism and Batesian mimicry require bright colours? A test, using European viper markings. Proc Biol Sci. However, the wind-fire toxin patients that were bitten by vipers and cobras are distinguished from the fire toxin patients bitten by Agkistrodon acutus and Trimeresurus stejnegeri in TCM.

Based on serum protein expression profiles, we observed a significant distinction in PCA and hierarchical clustering between the wind-fire toxin and fire toxin groups Figure 1B and 1C.

We observed two obvious clusters of significantly upregulated proteins, presented in Figure 1C. Therefore, exploring differences in the serum protein expression profile is effective to distinguish snakebites, as well as for biomarker and antivenom discovery.

Discovering the pathways the identified serum proteins are associated with offers an opportunity for biomarker discovery. DAPs were associated with the hydrogen peroxide catabolic process, carbon-oxygen lyase activity, and heme binding.

Previous studies have demonstrated that venom-induced toxicity elevates reactive oxygen species ROS and hydrogen peroxide levels, implying potential cytotoxicity of venom [ 11 Santhosh MS, Sundaram MS, Sunitha K, Kemparaju K, Girish KS.

Viper venom-induced oxidative stress and activation of inflammatory cytokines: a therapeutic approach for overlooked issues of snakebite management. Inflamm Res. The compound hydrogen peroxide is an important component of ROS, which regulates many cellular functions in limited concentrations, but can also cause damage of cellular organelles, DNA, and proteins when present in excessive concentrations, an effect known as oxidative stress [ 33 Marnett LJ.

Oxyradicals and DNA damage. The interaction network of proteins and drug compounds showed that hydrogen peroxide was highly associated with many DAPs Figure 5. These interacting DAPs were grouped into four clusters, including lipid metabolism and transport, IGF-mediated growth, oxygen transport, and innate immunity.

The venom-induced toxicity activates various oxidases and respiratory burst due to inflammation [ 34 Sampaio SC, Sousa-e-Silva MC, Borelli P, Curi R, Cury Y. Crotalus durissus terrificus snake venom regulates macrophage metabolism and function. J Leukoc Biol. Phospholipases A2 PLA2s are abundant components of venom in many snake species, and have the effect of blocking neuromuscular transmission and inducing acute muscle damage [ 35 Gutierrez JM, Lomonte B.

Phospholipases A2: unveiling the secrets of a functionally versatile group of snake venom toxins. However, the physiological roles of PLA2s remain unknown. We discovered that a large cluster in the protein interaction network is concentrated in the innate ubiquitin-proteasome.

Protein degradation may potentially be the cellular targets of PLA2s. The molecular composition of venom and serum from snakebite patients may be the most direct and credible way to evaluate the molecular mechanisms underlying the venom-induced toxicity process. Comparison of DAPs in snakebites from different snake species identifies potential biomarkers and provides theoretical support for TCM on the molecular level.

A few proteins participating in the networks were upregulated in the serum of the fire toxin group as compared to the wind-fire toxin group, such as TXN Thioredoxin , CETP Cholesteryl ester transfer protein , IGFBP7 Insulin-like growth factor binding protein 7 , MPO Myeloperoxidase , and SLC4A1 Solute carrier family 4.

Two proteins, FABP6 Fatty acid binding protein 6 and B3GNT1 Beta-1,3-N-acetylglucosaminyltransferase 1 , were only upregulated in the D subgroup Agkistrodon acutus , while four proteins, HSPA8 Heat shock 70kDa protein 8 , CKM Creatine kinase , SEMA4 semaphorin 4B , and SAA1 serum amyloid A1 were only unexpressed in the E subgroup Trimeresurus stejnegeri.

These potential protein biomarkers well illustrated in toxin classification of TCM theory, and provided more biomarkers for identification of snakebite by different snake species. Importantly, the combined DAPs from four snake species suggested that they were mainly involved in the interaction network of proteins and hydrogen peroxide.

Envenomation has been shown to induce redox status imbalance in a few snakes [ 36 Sachetto ATA, Rosa JG, Santoro ML. Rutin quercetinrutinoside modulates the hemostatic disturbances and redox imbalance induced by Bothrops jararaca snake venom in mice. Zengin S, Al B, Yarbil P, Taysi S, Bilinc H, Yildirim C, et al.

J Emerg Med. Aquilano K, Baldelli S, Ciriolo MR. Glutathione: new roles in redox signaling for an old antioxidant. Front Pharmacol. Thus, the DAPs associated with oxidative stress and antioxidant action could be regarded as prior consideration for experimental validation in the future.

Five proteins TXN, CETP, IGFBP7, MPO, and SLC4A1 were potential biomarkers to distinguish fire toxin and wind-fire toxin in classification of TCM theory, and a few proteins could identify snakebite of different snake species.

These potential protein biomarkers were connected into the interaction network of proteins and hydrogen peroxide, which indicated that the venom-induced toxicity of snakebites was associated with oxidative stress and antioxidant defense.

In the future, these potential biomarkers will need to be screened in a larger cohort of patients for clinical application. Open menu Brazil.

Methods: Cases of snakebite seen at the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine were grouped as follows: fire toxin - including four cases of bites by Agkistrodon acutus and three bites by Trimeresurus stejnegeri - and wind-fire toxin - four cases of bites by vipers and three bites by cobras.

Results: Principal component analysis and hierarchical clustering of unique proteins exhibited protein expression profiles of wind-fire toxins that are distinct from that of fire toxins.

Conclusions: Our results show that the pathways of snake venom-induced toxicity may form a protein network of antioxidant defense by regulating oxidative stress through interaction with hydrogen peroxide.
