生物活性

Alamandine, a member of the renin-angiotensin system (RAS), a vasoactive peptide, is an endogenous ligand of the G protein-coupled receptor MrgD. Alamandine targets to protect the kidney and heart through anti-hypertensive actions[1][2].

体外研究
(In Vitro)

Alamandine is generated by catalysis of Ang A via ACE2 or directly from Angiotensin 1-7 (Ang-(1-7)). Derived from angiotensin II (Ang II) by Ang II-converting enzyme 2 (ACE2), it shows vasodilating (thus protective) properties. Ang (1-7) can be decarboxylated to a peptide called Alamandine. Alamandine is also an endogenous peptide identified in human blood[1].
Alamandine elevates cAMP concentration in primary endothelial and mesangial cells, also suggesting Gs coupling[2].
Alamandine decreases secretion, expression, and blood levels of leptin. Alamandine induced expression of iNOS and plasminogen activator inhibitor-1 (PAI-1) in adipose tissue and isolated adipocytes[2].

体内研究
(In Vivo)

Alamandine (0.15  μL/h; administered by mini-osmotic pumps; for 6 weeks) treatment ameliorates hypertension and impaires left ventricle (LV) function in SHRs. Also decreases the mass gains of heart and lung in SHRs, suppresses cardiomyocyte cross-sectional area expansion, and inhibits the mRNA levels of atrial natriuretic peptide and brain natriuretic peptide[3].

Animal Model: Male spontaneously hypertensive rats (SHRs, 50-week-old)[3]
Dosage: 0.15  μL/h (~50 μg/kg/day)
Administration: Administered by mini-osmotic pumps; for 6 weeks
Result: Attenuated hypertension, alleviated cardiac hypertrophy, and improved LV function.
