angiotensin ii , human tfa

Angiotensin II (3-8), human (TFA), is an angiotensin AT1 receptor agonist with reduced activity.

Angiotensin II is a potent direct vasoconstrictor, causing arteries and veins to constrict, so leading to an increase in blood pressure.

Angiotensin II human TFA is a potent vasoconstrictor in the renin-angiotensin system that regulates blood pressure through interactions with AT1R and AT2R receptors. It activates sympathetic nerve activity, promotes aldosterone synthesis and renal function, induces proliferation of vascular smooth muscle cells, and enhances type I and III collagen production in fibroblasts, leading to vascular and myocardial thickening and fibrosis. It also triggers apoptosis and promotes capillary formation, making it suitable for establishing models of cardiac hypertrophy, hypertension, and abdominal aortic aneurysm.

Angiotensin I-13C6,15N (human, mouse, rat) TFA is a labeled version of Angiotensin I, using isotopes 13C and 15N, specifically targeted for human, mouse, and rat studies. This compound serves as a precursor to angiotensin II, which is formed through the cleavage by angiotensin-converting enzyme (ACE).
