What is Angiotensin-(1-9)?
A nine-amino-acid angiotensin fragment formed through ACE2 and related peptidases. It is considered part of the protective arm of the renin-angiotensin system and may oppose some effects of angiotensin II.
Key Benefits & Mechanisms
ACE2-pathway modulation
vasoprotective signaling
endothelial support
blood-pressure balance
Research Summary
Angiotensin-(1-9) is part of the counter-regulatory branch of the renin-angiotensin system and has been linked to endothelial nitric oxide signaling and cardioprotection. Experimental work suggests effects on vascular tone, post-injury remodeling, and hypertension-related pathways.

Carperitide
Recombinant human atrial natriuretic peptide (α-hANP)
Recombinant human atrial natriuretic peptide used mainly in acute heart failure and perioperative volume overload. It promotes natriuresis, vasodilation, and suppression of RAAS signaling to lower preload and afterload.
CardiovascularNesiritide
Recombinant human B-type natriuretic peptide (BNP-32)
Synthetic BNP used to counteract fluid overload and elevated cardiac filling pressures. It increases cyclic GMP, causing venous and arterial vasodilation plus natriuresis.
CardiovascularUlaritide
Synthetic human urodilatin
Urodilatin is a renal natriuretic peptide derived from the proANP precursor and studied as an IV heart-failure therapy. It produces strong natriuresis and vasodilation with a relatively rapid onset.
CardiovascularCenderitide
CD-NP chimeric natriuretic peptide
Cenderitide is a designer natriuretic peptide combining features of CNP and dendroaspis natriuretic peptide. It was engineered to provide balanced natriuretic and vasodilatory activity with potential renal-sparing effects.
