The Venom of Australian Spiders

2015
Australia is home to an estimated 10,000 species of spider, including species from the Latrodectus genera and Atracinae family, two of the four widely recognized medically significant spider groups. It is predicted in excess of 5,000 spider bite cases occurring annually in Australia, predominantly by spiders that have not shown any medical relevance ...

Latarcins: versatile spider venom peptides

Cellular and Molecular Life Sciences, 2015
Arthropod venoms feature the presence of cytolytic peptides believed to act synergetically with neurotoxins to paralyze prey or deter aggressors. Many of them are linear, i.e., lack disulfide bonds. When isolated from the venom, or obtained by other means, these peptides exhibit common properties.

Assay of Spider Venom and Antivenene in Drosophila

Nature, 1956
DURING studies on the toxicity of the venom of the Australian red back spider (L. hasseltii) it was found that the venom injected into Drosophila causes paralysis of the insect. This effect has been utilized for assaying antivenene.

Neurotoxins and Necrotoxins of Spider Venoms

Journal of Toxicology: Toxin Reviews, 1986
Abstractalpha-Latrotoxin, the systemic neurotoxin isolated from the venom of the Mediterranean black widow spider (Latrodectus mactans tredecimeuttatus) remains the most studied of spider venom toxins. Although some variation is reported in the chemical properties of this protein neurotoxin, all workers agree that it causes a variety of nenous tissue ...

Venomous snake bites, scorpions, and spiders

2014
Neurologic dysfunction due to natural neurotoxins is an important, but neglected, public health hazard in many parts of the world, particularly in the tropics. These toxins are produced by or found among a variety of live forms that include venomous snakes, arthropods such as scorpions, spiders, centipedes, stinging insects (Hymenoptera), ticks ...

Collagenolytic activity of snake and spider venoms

Toxicon, 1967
Abstract The venoms of the snakes B. atrox , B. Jararaca , C. durissus , A. piscivorus , and the spiders P. fera , L. erythrognatha possess proteolytic activity which attacks gelatine, casein and azocoll. Denatured (heat, urea) collagen is digested too. However, native collagen is not attacked by the enzymes present in the venoms investigated.

The Acylpolyamines from Spider Venoms

2012
Abstract Acylpolyamines are low molecular mass toxins occurring exclusively in the venoms from solitary wasps and some groups of spiders. Their chemical structures have been elucidated using hyphenated techniques of mass spectrometry, such as LC–MS and MS/MS, or through direct analysis with different types of NMR analyses.

Proteome and peptidome profiling of spider venoms

Expert Review of Proteomics, 2008
Spider venoms are an important source of novel molecules with different pharmacological properties. Recent technological developments of proteomics, especially mass spectrometry, have greatly promoted the systematic analysis of spider venom. The enormous diversity of venom components between spider species and the lack of complete genome sequence, and ...

New linear polyamine derivatives in spider venoms

Toxicon, 2005
Linear free polyamines were characterized in the venom of the spiders Agelenopsis aperta, Hololena curta, and Paracoelotes birulai by RP-HPLC coupled to mass spectrometry. The several linear polyamines found were tetramine, pentamine, and hexamine derivatives. Some of these natural products were identified as N-hydroxylated, guanidylated, or acetylated
