 Use of Big Endothelin-1 (22-38), human


Big Endothelin-1 (22-38), human is derived from human, is the 22-38 fragment of Big Endothelin-1 (ET-1) (1-38). Big ET-1 (1-38) is a propeptide of ET-1, which has potent and long-lasting vasoconstrictor effects, equips a specific enzymatic cleavage of the 38 amino acid chain to form ET-1 (1-21) and the C-terminal fragment Big ET-1 (22-38)[1].

In Vitro Big Endothelin-1 (22-38), human (0.1 μM; 30 min) induces the release of prostacyclin (PGI2) from rabbit, guinea pig, and rat lungs[2].
In Vivo Big Endothelin-1 (22-38), human (3 nM/kg; intra-arterial injection; single dose) produces a significant rise in left ventricular systolic pressure (LVSP) in anesthetized rabbits, and is enhanced by cyclooxygenase inhibitor Indomethacin (HY-14397) (5 mg/kg i.v.) significantly[3]. Big Endothelin-1 (22-38), human (3 nM/kg; intravascular method; single dose), has no antiaggregatory properties for platelet induced by ADP in rabbits[3].
