5-Hydroxytryptamine in Scorpion Venom
Nature, 1956IN the course of an investigation of the toxic factors in the venom of Leiurus quinquestriatus (H. and E., 1829), one of the constituents of the venom has been found to be 5-hydroxytryptamine.

Scorpion venoms, kidney and potassium
Toxicon, 2013Scorpion venoms cause renal injury by the interaction of renal ischemia due to intense renal vasoconstriction and inflammatory reactions due to proinflammatory cytokines and mediators. Renal vasoconstriction is not only induced by catecholamine storm but also by angiotensin II and the direct action of venom on vascular ion channels.

Glycaemic responses to scorpion venom
Toxicon, 1972Hyperglycaemia and liver and muscle glycogenolysis were produced in the rat by scorpion venom. These epinephrine-like effects may be mediated by the serotonin present in the venom. Liver slices, excised from venom treated rats, and incubated in Krebs-Ringer solution with bicarbonate and glucose, exhibited an increase of free fatty acid release ...

Scorpion venom phospholipases A2: A minireview
Toxicon, 2020Many venomous species, including snakes, bees and scorpions, contain a variety of secreted phospholipases A2 (sPLA2) that contribute to prey digestion and venom toxicity. Based on their primary structures, the different venom sPLA2 have been classified into four groups I, II, III and IX.

Snapshots of scorpion venomics
Journal of Arid Environments, 2015Scorpions are particularly well adapted to survival in extreme habitats (especially arid and semi-arid environments) and their ability to produce and deliver venoms is an important factor in this success. Scorpion venoms are very complex mixtures of different proteins and peptides.

Physiological Action of Scorpion Venom
The American Journal of Tropical Medicine and Hygiene, 1960Summary Venom of the scorpion, Centruroides sculpturatus Ewing, caused hypertension, respiratory failure, and skeletal muscle stimulation in anesthetized animals. No significant action of the venom was found on isolated skeletal muscle preparations.

Venom of the Scorpion Vejovis spinigerus
Science, 1968The chemical composition of lyophilized venom from Vejovis spinigerus is reported. At least 13 distinct bands were obtained on disc electrophoresis; on Sephadex G-50, four major peaks were found. The lethal activity was associated with the second peak.

Scorpion Venom Peptides without Disulfide Bridges
IUBMB Life (International Union of Biochemistry and Molecular Biology: Life), 2005Several hundred disulfide-bridged neurotoxic peptides have been characterized from scorpion venom; however, only few scorpion venom peptides without disulfide bridges have been identified and characterized. These non-disulfide-bridged peptides (NDBPs) are a novel class of molecules because of their unique antimicrobial, immunological or cellular ...

An Immunological Evaluation of Scorpion Venoms
The American Journal of Tropical Medicine and Hygiene, 1962Summary Studies have been presented on the interrelationships existing between scorpion venoms and antisera prepared against these venoms. Experiments designed to demonstrate reactivity of a number of venom samples representing Families Buthidae and Vejovidae have shown that a large number of antigenic fractions are shared among members of both of ...

Anticoagulants from Scorpion Venoms
2010Venom from at least six distinct families of scorpion: Buthidae, Caraboctonidae, Iuridae, Ischnuridae, Scorpionidae and Vejovidae are known to contain many pharmacologically active peptides and some proteins involved in coagulation. The list of such compounds is increasing with time and newly described cases.
