Product Information

• Name: Sarafotoxin S6c

• Description: Sarafotoxin S6c, 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. Compared to the sarafotoxin isopeptide S6b, S6c is less toxic with a 100 to 10,000-fold reduced affinity for the ETA receptor, therefore acts as a selective agonist to the ETB receptor. One study demonstrated that when sarafotoxin 6c was used to activate ETB receptors in rats there was an increase in arterial pressure, known as S6c-induced hypertension.As the upregulation of Endothelin-1 (ET-1) is related to circulatory-system diseases, the interaction between ET-1 and its receptors is highly important for development of endothelin receptor antagonist treatments. Sarafotoxin S6c can be used as a pharmacological reagent to study these interactions.
