Scorpions are well known for their dangerous stings that can result in severe consequences for human beings, including death. Neurotoxins present in their venoms are responsible for their toxicity. Due to their medical relevance, toxins have been the driving force in the scorpion natural compounds research field. On the other hand, for thousands of years, scorpions and their venoms have been applied in traditional medicine, mainly in Asia and Africa. With the remarkable growth in the number of characterized scorpion venom components, several drug candidates have been found with the potential to tackle many of the emerging global medical threats. Scorpions have become a valuable source of biologically active molecules, from novel antibiotics to potential anticancer therapeutics. Other venom components have drawn attention as useful scaffolds for the development of drugs. This review summarizes the most promising candidates for drug development that have been isolated from scorpion venoms.

Ex Output:
Scorpion venom components as potential candidates for drug development

A new species of parvovirus, tentatively named human bocavirus 4 (HBoV4), was genetically characterized. Among 641 feces samples obtained from children and adults, the most commonly detected bocavirus species were, in descending order, HBoV2, HBoV3, HBoV4, and HBoV1, with an HBoV2 prevalence of 21% and 26% in Nigerian and Tunisian children, respectively. HBoV3 or HBoV4 species were found in 12 of 192 patients with non-polio acute flaccid paralysis in Tunisia and Nigeria and 0 of 96 healthy Tunisian contacts (P p ). Evidence of extensive recombination at the NP1 and VP1 gene boundary between and within bocavirus .01 species was found. The high degree of genetic diversity seen among the human bocaviruses found in feces specimens, relative to the highly homogeneous HBoV1, suggest that this worldwide-distributed respiratory pathogen may have recently evolved from an enteric bocavirus after acquiring an expanded tropism favoring the respiratory tract. Elucidating the possible role of the newly identified enteric bocaviruses in human diseases, including acute flaccid paralysis and diarrhea, will require further epidemiological studies. Parvoviruses are small, non-lipid-enveloped, environmentally resistant viral particles with single-stranded linear DNA genomes that frequently infect animals through the fecal-oral route [1] . Parvoviruses can cause numerous symptoms in animals, including enteritis, panleukopenia, hepatitis, erythrocyte aplasia, and cerebellar ataxia [1]. Efficacious vaccines against animal parvovirus infections are widely employed [2] [3] [4] . Following the identification of the human parvovirus

of the virus per se and cellular NF-B activity; and (ii) to study the underling mechanisms. We found that tylophorine-based compounds target the TGEV viral RNA and effectively inhibit TGEV replication. NF-B inhibition also leads to anti-TGEV replication. NF-B activation induced by TGEV infection was found to be associated with two convergent pathways, IKK-2_IB/p65 and JAK2 mediated p65 phosphorylation, in swine testicular cells. JAK2 inhibition either by CYT387 (a JAK family inhibitor) or by silencing JAK2-expression revealed a dominant JAK2 mediated p65 phosphorylation pathway for NF-B activation and resulted in NF-B inhibition, which overrode the IB regulation via the IKK-2. Finally, tylophorine-based compounds work cooperatively with CYT387 to impart comprehensive anti-TGEV activities. The combination treatment, wherein a tylophorine compound targets TGEV and a JAK2 inhibitor blocks the alternative dominant NF-B activation mediated by JAK2, is more effective and comprehensive than either one alone and constitutes a feasible approach for the treatment of SARS-CoV or MERS-CoV. Coronaviruses are animal viruses containing an enveloped, positive-sense, single-stranded RNA genome; and include the common cold human coronavirus (CoV)-229E & CoV-OC43, severe acute respiratory syndrome (SARS) CoV, Middle East respiratory syndrome (MERS) CoV, porcine transmissible gastroenteritis virus (TGEV), and murine hepatitis virus (MHV) etc 1-3 . Since the 2003 SARS outbreak (which had a mortality rate of ~10%), novel anti-SARS-CoV treatments have been vigorously pursued. No new cases of SARS have been reported since the 2003 outbreak, but another novel coronavirus (MERS-CoV), this time with a mortality rate of ~35%, came to light in 2012 4 . To date, neither a commercially available vaccine for human coronaviruses nor a specific treatment for SARS-CoV or MERS-CoV is available. Coronaviruses primarily infect the upper respiratory and gastrointestinal tract and induce host inflammation 5 . Nuclear factor B (NF-B) activation by coronaviruses is usually responsible for mediating the production of pro-inflammatory cytokines and chemokines and thus plays an important role in the pathogenesis of disease caused by coronaviruses 6, 7 . Inhibition of NF-B-mediated inflammation induced by coronavirus in mice was reported to increase the survival rate 6 . Thus, NF-B inhibitors constitute a promising class of antivirals in infections caused by pathogenic coronaviruses. However, targeting NF-B is limited by intrinsic pathway complexity, cross talk with other pathways, and drug resistance 8 . In addition, many small chemical molecules targeting either viral entry or the intracellular viral life cycle were reported to impart anti-coronavirus activity 2, 9, 10 . Despite these advances, however, SARS-CoV and MERS-CoV remain untreatable diseases for which novel therapies are sought. Published: xx xx xxxx OPEN www.nature.com/scientificreports/ 2 Scientific RepoRts | 7: 4105 | Tylophorine based compounds, whether isolated from plants, e.g. Asclepiadaceae and Moraceae or chemically synthesized, exert potent anti-coronaviral activities against a variety of coronaviruses including SARS-CoV, MHV, and TGEV 11, 12 , but both the underlying mechanism(s) of this inhibitory effect and the target are unknown. NF-B is significantly activated after infection by coronaviruses, e.g. TGEV, and MHV etc 6, 7, [13] [14] [15] . Otherwise, coronaviral nucleocapsid (N) protein plays a vital role in the regulation of viral genome replication and host gene transcription 16 . Therefore, the combination treatment for the inhibition of coronavirus per se, e.g. viral genome replication, and blocking cellular NF-B activation by coronaviruses, is a promising approach for the development of anti-coronavirals. TGEV infected swine testicular (ST) cells constitute a surrogate system for the search and study of potential anti-coronavirus agents 11, 12, 17 . Herein, we report: (1) tylophorine-based compounds exert potent anti-TGEV replication by directly targeting the viral RNA/ribonucleoprotein (RNP) complex for viral replication/synthesis; (2) NF-B inhibition also leads to anti-TGEV replication; (3) A combination treatment consisting of both a tylophorine compound and an NF-B inhibitor acts additively or synergically to more effectively and comprehensively inhibit TGEV replication than either (1) or (2) alone.
