Sarafotoxin S6b

Catalog No.: A60267
Endothelin Receptor Agonist
Sarafotoxin S6b is a potent vasoconstrictor peptide and a non-selective agonist of endothelin receptors. This compound effectively induces contraction in isolated human coronary arteries, exhibiting Ki values of 0.27 nM, 0.55 nM, and 19.5 nM for the coronary artery, saphenous vein, and coronary artery, respectively. Sarafotoxin S6b is valuable for research applications focused on cardiovascular physiology and the roles of endothelin signaling in vascular constriction.
