Insect-selective spider toxins targeting voltage-gated sodium channels [PDF]
, 2007 The voltage-gated sodium (Nav) channel is a target for a number of drugs, insecticides and neurotoxins. These bind to at least seven identified neurotoxin binding sites and either block conductance or modulate Nav channel gating.

Brown Spider (Loxosceles genus) Venom Toxins: Tools for Biological Purposes
Toxins, 2011 Venomous animals use their venoms as tools for defense or predation. These venoms are complex mixtures, mainly enriched of proteic toxins or peptides with several, and different, biological activities.

Spider Venoms: Biochemical Aspects [PDF]
American Zoologist, 1969 SYNOPSIS. The venoms of spiders are quite complex and contain an array of biologically active components. The majority of studies on the biochemical aspects of these venoms have utilized four species: Phoneutria fera, Lycosa erythrognatha, Atrax robustus , and Latrodectus mactans .

Spider venom administration impairs glioblastoma growth and modulates immune response in a non-clinical model. [PDF]
, 2020 Molecules from animal venoms are promising candidates for the development of new drugs. Previous in vitro studies have shown that the venom of the spider Phoneutria nigriventer (PnV) is a potential source of antineoplastic components with activity in ...

Are ticks venomous animals? [PDF]
, 2017 [Introduction]: As an ecological adaptation venoms have evolved independently in several species of Metazoa. As haematophagous arthropods ticks are mainly considered as ectoparasites due to directly feeding on the skin of animal hosts. Ticks are of major
