Abstract
Polyamines (PAs) are polycationic biogenic amines ubiquitously present in all life forms and are involved in molecular signaling and interaction, determining cell fate (e.g., cell proliferation, dif-ferentiation, and apoptosis). The intricate balance in the PAs' levels in the tissues will determine whether beneficial or detrimental effects will affect homeostasis. It's crucial to note that endoge-nous polyamines, like spermine and spermidine, play a pivotal role in our understanding of neu-rological disorders as they interact with membrane receptors and ion channels, modulating neuro-transmission. In spiders and wasps, monoamines (histamine, dopamine, serotonin, tryptamine) and polyamines (spermine, spermidine, acyl polyamines) comprise, with peptides and other sub-stances, the low molecular weight fraction of the venom. Acylpolyamines are venom components exclusively from spiders and a species of solitary wasp, which cause inhibition chiefly of iono-tropic glutamate receptors (AMPA, NMDA, and KA iGluRs) and nicotinic acetylcholine receptors (nAChRs). The first venom acylpolyamines ever discovered (argiopines, Joro and Nephila toxins, and philanthotoxins) have provided templates for the design and synthesis of numerous analogs. Thus far, analogs with high potency exert their effect at nanomolar concentrations, with high se-lectivity toward their ionotropic and ligand receptors. These potent and selective acylpolyamine analogs can serve biomedical purposes and pest control management. The structural modification of acylpolyamine with photolabile and fluorescent groups converted these venom toxins into use-ful molecular probes to discriminate iGluRs and nAchRs in cell populations. In various cases, the linear polyamines, like spermine and spermidine, constituting venom acyl polyamine backbones, have served as cargoes to deliver active molecules via a polyamine uptake system on diseased cells for targeted therapy. In this review, we examined examples of biogenic amines that play an essential role in neural homeostasis and cell signaling, contributing to human health and disease outcomes, which can be present in the venom of arachnids and hymenopterans. With an empha-sis on the spider and wasp venom acylpolyamines, we focused on the origin, structure, derivatiza-tion, and biomedical and biotechnological application of these pharmacologically attractive, chemically modular venom components.

Abstract
The complex process of pain control commonly involves the use of systemic analgesics; however, in many cases, a more potent and effective polypharmacological approach is needed to promote clinically significant improvement. Additionally, considering side effects caused by current painkillers, drug discovery is once more turning to nature as a source of more efficient therapeutic alternatives. In this context, arthropod venoms contain a vast array of bioactive substances that have evolved to selectively bind to specific pharmacological targets involved in the pain signaling pathway, playing an important role as pain activators or modulators, the latter serving as promising analgesic agents. The current review explores how the pain pathway works and surveys neuroactive compounds obtained from arthropods' toxins, which function as pain modulators through their interaction with specific ion channels and membrane receptors, emerging as promising candidates for drug design and development.

Combining multidimensional liquid chromatography and MALDI-TOF-MS for the fingerprint analysis of secreted peptides from the unexplored sea anemone species Phymanthus crucifer.

Abstract
Sea anemones are sources of biologically active proteins and peptides. However, up to date few peptidomic studies of these organisms are known; therefore most species and their peptide diversity remain unexplored. Contrasting to previous venom peptidomic works on sea anemones and other venomous animals, in the present study we combined pH gradient ion-exchange chromatography with gel filtration and reversed-phase chromatography, allowing the separation of the 1-10 kDa polypeptides from the secretion of the unexplored sea anemone Phymanthus crucifer (Cnidaria/Phymanthidae). This multidimensional chromatographic approach followed by MALDI-TOF-MS detection generated a peptide fingerprint comprising 504 different molecular mass values from acidic and basic peptides, being the largest number estimated for a sea anemone exudate. The peptide population within the 2.0-3.5 kDa mass range showed the highest frequency whereas the main biomarkers comprised acidic and basic peptides with molecular masses within 2.5-6.9 kDa, in contrast to the homogeneous group of 4-5 kDa biomarkers found in sea anemones such as B. granulifera and B. cangicum (Cnidaria/Actiniidae). Our study shows that sea anemone peptide fingerprinting can be greatly improved by including pH gradient ion-exchange chromatography into the multidimensional separation approach, complemented by MALDI-TOF-MS detection. This strategy allowed us to find the most abundant and unprecedented diversity of secreted components from a sea anemone exudate, indicating that the search for novel biologically active peptides from these organisms has much greater potential than previously predicted.

Abstract
Arachnids have a venom apparatus and secrete a complex chemical mixture of low molecular mass organic molecules, enzymes and polypeptide neurotoxins designed to paralyze or kill their prey. Most of these toxins are specific for membrane voltage-gated sodium channels, although some may also target calcium or potassium channels and other membrane receptors. Scorpions and spiders have provided the greatest number of the neurotoxins studied so far, for which, a good number of primary and 3D structures have been obtained. Structural features, comprising a folding that determines a similar spatial distribution of charged and hydrophobic side chains of specific amino acids, are strikingly common among the toxins from spider and scorpion venoms. Such similarities are, in turn, the key feature to target and bind these proteins to ionic channels. The search for new insecticidal compounds, as well as the study of their modes of action, constitutes a current approach to rationally design novel insecticides. This goal tends to be more relevant if the resistance to the conventional chemical products is considered. A promising alternative seems to be the biotechnological approach using toxin-expressing recombinant baculovirus. Spider and scorpion toxins having insecticidal activity are reviewed here considering their structures, toxicities and action mechanisms in sodium channels of excitable membranes.

Abstract
Neurodegeneration induced by excitatory neurotransmitter glutamate is considered to be of particular relevance in several types of acute and chronic neurological impairments ranging from cerebral ischaemia to neuropathological conditions such as motor neuron disease, Alzheimer's, Parkinson's disease and epilepsy. The hyperexcitation of glutamate receptors coupled with calcium overload can be prevented or modulated by using well-established competitive and non-competitive antagonists targeting ion/receptor channels. The exponentially increasing body of pharmacological evidence over the years indicates potential applications of peptide toxins, due to their exquisite subtype selectivity on ion channels and receptors, as lead structures for the development of drugs for the treatment of wide variety of neurological disorders. This review comprehensively highlights the overview of the diversity in the molecular as well as neurobiological mechanisms of different peptide toxins derived from venomous animals with particular reference to neuroprotection. In addition, the potential applications of peptide toxins in the diagnosis and treatment of neurological disorders such as neuromuscular disorders, epilepsy, Alzheimer's and Parkinson's diseases, gliomas and ischaemic stroke and their future prospects in the diagnosis as well as in the therapy are addressed.

Abstract
We designed and synthesized a series of the polyamine derivatives as potent Ca(2+)-permeable AMPA receptor antagonists. In the course of this study, we found that the polyamine derivatives exhibited strong hypotensive activity which was undesirable activity for neuroprotective agents. Therefore, we tried to find non-hypotensive antagonists by structural modification of such compounds. Through this derivatization, we obtained the diamine compounds having desired profiles. Especially, compound 8f, which was non-hypotensive and potent Ca(2+)-permeable AMPA receptor antagonist, showed neuroprotective effects in transient global ischemia models in gerbils.

Abstract
Three insecticidal polypeptide toxins (F5.5, F5.6, F5.7) with molecular masses 4973, 4993 and 5159Da were isolated from the venom of the central Asian spider Segestria florentina. These toxins caused the complete flaccid paralysis of Heliothis virescens (Lepidoptera: Noctuidae) larvae (LD(50) 4-10 microg/g), whereas they were inactive upon intravenous injections into mice. On the basis of N-terminal amino acid sequences a family of eight genes encoding highly homologues polypeptides (SFI1-SFI8) was revealed, some of which encode polypeptides actually demonstrated to be present in S. florentina venom. All deduced polypeptides consist of 46 amino acids residues. Comparison of primary structures of SFI1-SFI8 with other spider toxins suggests that this family might share structural and functional relationships with other small spider neurotoxins, several of which are known to be highly selective agonists/antagonists of different voltage-dependent Ca(2+) channels.

Abstract
Spider venoms contain toxins that specifically immobilize and kill insects. We report the purification and characterization of a new insect-specific toxin named covalitoxin-II (Cvtx-II; mass, 3406. 24+/-0.64), from Coremiocnemis validus (Singapore tarantula) venom. The complete 31 amino acid sequence of Cvtx-II has been determined and it shows less than 40% identity with spider toxins. However, Cvtx-II has conserved cystine motif analogous to other spider and omega-conotoxins. Cvtx-II was chemically synthesized and identified with the native Cvtx-II. Synthetic Cvtx-II induced insect-specific non-lethal excitatory activity when injected into crickets, but not in cockroaches and mice.

Abstract
alpha-latrocrustatoxin (alpha-LCTX), a component of black widow spider venom (BWSV), produced a 50-fold increase in the frequency of spontaneously occurring miniature excitatory postsynaptic potentials (mEPSPs) at crayfish neuromuscular junctions but did not alter their amplitude distribution. During toxin action, periods of high-frequency mEPSP discharge were punctuated by periods in which mEPSP frequency returned toward control levels. EPSPs were increased in amplitude during periods of enhanced mEPSP discharge. alpha-LCTX had no effect when applied in Ca(2+)-free saline, but subsequent addition of Ca(2+) caused an immediate enhancement of mEPSP frequency even when alpha-LCTX was previously washed out of the bath with Ca(2+)-free saline. Furthermore removal of Ca(2+) from the saline after alpha-LCTX had elicited an effect immediately blocked the action on mEPSP frequency. Thus alpha-LCTX binding is insensitive to Ca(2+), but toxin action requires extracellular Ca(2+) ions. Preincubation with wheat germ agglutinin prevented the effect of alpha-LCTX but not its binding. These binding characteristics suggest that the toxin may bind to a crustacean homologue of latrophilin/calcium-independent receptor for latrotoxin, a G-protein-coupled receptor for alpha-latrotoxin (alpha-LTX) found in vertebrates. alpha-LCTX caused "prefacilitation" of EPSP amplitudes, i.e., the first EPSP in a train was enhanced in amplitude to a greater degree than subsequent EPSPs. A similar alteration in the pattern of facilitation was observed after application of the Ca(2+) ionophore, A23187, indicating that influx of Ca(2+) may mediate the action of alpha-LCTX. In nerve terminals filled with the Ca(2+) indicator, calcium green 1, alpha-LCTX caused increases in the fluorescence of the indicator that lasted for several minutes before returning to rest. Neither fluorescence changes nor toxin action on mEPSP frequency were affected by the Ca(2+) channel blockers omega-agatoxin IVA or Cd(2+), demonstrating that Ca(2+) influx does not occur via Ca(2+) channels normally coupled to transmitter release in this preparation. The actions of alpha-LCTX could be reduced dramatically by intracellular application of the Ca(2+) chelator, bis-(o-aminophenoxy)-N,N,N', N'-tetraacetic acid. We conclude that induction of extracellular Ca(2+) influx into nerve terminals is sufficient to explain the action of alpha-LCTX on both spontaneous and evoked transmitter release at crayfish neuromuscular junctions.
