Natriuretic action of angiotensin(1-7)

Br J Pharmacol. 1994 Jan;111(1):1-3. doi: 10.1111/j.1476-5381.1994.tb14014.x.


Evidence that angiotensin(1-7) (Ang(1-7)) is biologically active and can be synthesized by the kidney prompted us to examine its actions in the rat, isolated kidney. Ang(1-7) had three major effects producing, (1) a substantial natriuresis and diuresis, (2) an increase in urinary sodium concentration associated with a fall in potassium concentration and (3) an increase in glomerular filtration rate without affecting renal vascular resistance. Thus, Ang(1-7) may participate in the renal effects of the renin-angiotensin system.
