Angiotensin II human (Ang II) is a biologically active peptide, a vasoconstrictor. Angiotensin II interacts with AT1R and AT2R to regulate blood pressure, stimulate sympathetic nerves, and increase aldosterone biosynthesis and renal activity in humans.

Angiotensin II human acetate (DRVYIHPF acetate) is a vasoconstrictor that mainly acts on the AT1 receptor.

Alamandine can be formed from angiotensin A by action of ACE-2 or directly from angiotensin-(1-7) by decarboxylation of its aspartate residue. The angiotensin A analog produces effects resembling those of Ang II (1-7). However, it acts independently of the two known vasodilators receptors of the RAS (Mas and angiotensin II type 2). To produce its effects, alamandine binds to the Mas-related receptor, MrgD. A novel orally active formulation of alamandine produced a long-term antihypertensive effect in spontaneously hypertensive rats and cardioprotective effects. These novel findings will be helpful for developing a new understanding of the RAS, a key regulator of blood pressure and fluid balance. The heptapeptide could serve as a model peptide, e.g. in the development and evaluation of analytical methods.

TRV120027 TFA is a β-arrestin-1-biased agonist of the angiotensin II receptor type 1 (AT1R) and engages ß-arrestins while blocking G-protein signaling.

Angiotensin III, human, mouse (Angiotensin III, human, mouse(3TFA))(3TFA) is an endogenous angiotensin II receptor (AT2R) agonist(IC50s of 0.648 nM).

Angiotensin 1-7 (Ang-(1-7)) acetate, an endogenous heptapeptide from the renin-angiotensin system (RAS), exhibits cardioprotective effects through its anti-inflammatory and anti-fibrotic activities in cardiac cells. It effectively inhibits purified canine ACE activity (IC 50 =0.65 μM) and serves as a local synergistic modulator of kinin-induced vasodilation by hindering ACE and facilitating nitric oxide release. Additionally, this compound prevents Ang II-induced proliferation and hypertrophy in smooth muscle cells, alongside demonstrating antiangiogenic and growth-inhibitory effects on the endothelium [1] [2] [3].

Angiotensin (1-7) (ASP-ARG-VAL-TYR-ILE-HIS-PRO) is a synthetic heptapeptide identical to endogenous angiotensin-(1-7) , inhibits purified canine ACE activity (IC50=0.65 μM) with vasodilator and antiproliferative activities.

Atrial Natriuretic Peptide (ANP) (1-28),rat (TFA) is the main circulating forms of Atrial Natriuretic Peptide (ANP) in rats, which strongly inhibit the secretion of Ang II - stimulated endothelin-1.
