Description

Sarafotoxin S6b, sourced from the venom of the Atractaspis engaddensis snake family, is one of four (S6a-d) isopeptides of the Sarafotoxins. This product is a synthetically produced toxin, containing disulfide bonds between Cys1-Cys15 and Cys3-Cys11.Due to their structural and functional homology to the endothelin peptides, Sarafotoxins can enhance vasoconstriction through stimulating the class A G-protein-coupled, endothelin ETA and ETB receptors. This in turn leads to left ventricular dysfunction and bronchoconstriction.
As the most potent Sarafotoxin, sarafotoxin S6b binds to both ETA and ETB receptors with a similar affinity to Endothelin-1. This is evident as when given to mice intravenously, sarafotoxin S6b caused cardiac arrest and death in mice almost immediately. Additional characteristics of S6b is its matrix metalloproteinase inhibitory activity due to it exhibiting a fold which is also found in the core region of tissue inhibitors of metalloproteinases (TIMPs).
Sarafotoxin S6b can be used as a pharmacological reagent to study the interactions of Endothelins and their corresponding receptors. This product is available as a 0.1mg vial.
