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
  • 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
  • to study its association with influenza A virus (IAV) infection

Biochem/physiol Actions

Angiotensin fragment 1-7 is a biologically active heptapeptide of the renin-angiotensin system (RAS). 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). 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.

Resolution failure of exacerbated inflammation triggered by Influenza A virus (IAV) prevents return of pulmonary homeostasis and survival, especially when associated with secondary pneumococcal infection. Therapeutic strategies based on pro-resolving molecules have great potential against acute inflammatory diseases. Angiotensin-(1-7) [Ang-(1-7)]

Ventilator-induced diaphragmatic dysfunction (VIDD) is a common event during mechanical ventilation (MV) leading to rapid muscular atrophy and contractile dysfunction. Recent data show that renin-angiotensin system is involved in diaphragmatic skeletal muscle atrophy after MV. In particular, angiotensin-II can induce

Regional vascular responses to angiotensin (Ang)-(1-7), a heptapeptide derivative of Ang II were investigated in the feline hindquarters and mesenteric vascular beds under conditions of controlled flow. In the mesenteric vascular bed, injections of Ang-(1-7) in doses of 1, 3

Angiotensin-(1-7) (Ang-(1-7)) modulates the Na+-ATPase, but not the Na+,K+-ATPase activity present in pig kidney proximal tubules. The Na+-ATPase, insensitive to ouabain, but sensitive to furosemide, is stimulated by Ang-(1-7) (68% by 10(-9) M), in a dose-dependent manner. This effect is

Aminopeptidases metabolize angiotensin II to angiotensin-(2-8) (=angiotensin III) and angiotensin-(3-8) (=angiotensin IV), and carboxypeptidases generate angiotensin-(1-7) from angiotensin I and II. Angiotensin-converting enzyme (ACE) inhibitors and/or angiotensin II type 1 (AT1) receptor blockers affect the concentrations of these metabolites, and
