Description

Application

Angiotensin Fragment 1-7 acetate salt hydrate has been used:

• to evaluate its effects on a rat model of ventilator-induced diaphragmatic dysfunction (VIDD) with neuromuscular blocking agent infusion[1]
• to unilaterally inject into the lateral preoptic area (LPA) to study its effects on intravesical pressure, arterial pressure, heart rate, and renal conductance in the female rats[2]
• to study its association with influenza A virus (IAV) infection[3]

Biochem/physiol Actions

Angiotensin fragment 1-7 is a biologically active heptapeptide of the renin-angiotensin system (RAS).[3] It is associated with anti-inflammatory and anti-fibrotic effects in many inflammatory diseases such as asthma, dyslipidemia, renal injury, arthritis, and lung fibrosis. Angiotensin fragment 1-7 acts as a pro-resolving mediator and induces resolution of inflammation via Mas receptor (MasR).[3] It is responsible for relaxation in several vascular beds. Angiotensin fragment 1-7 has a dual action of an angiotensin II type 1 (AT1) receptor agonist and antagonist depending on the presence of angiotensin II. It also serves as a substrate for angiotensin-converting enzyme (ACE). Sometimes, angiotensin fragment 1-7 prevents ACE activity leading to decreased angiotensin II generation and improved bradykinin-induced vasodilatation.[4]
