Introduction. Since the discovery of angiotensin (Ang)-converting enzyme 2 (ACE2) in 2000, 1,2 our understanding of the renin-angiotensin system has been greatly expanded, and an important role for the ACE2-Ang (1-7)-Mas receptor axis within the overall renin-angiotensin system is now generally accepted. 3 - 5 This system operates as an antagonist to the system's pressor branch. Angiotensin II (Ang II), the physiologically active component of the renin-angiotensin system, plays an important role in the regulation of the cardiovascular and renal systems. Based on their different pharmacological and biochemical properties, two distinct subtypes of Ang II receptor have been defined and designated as type 1 (AT 1 ) and type 2 (AT 2 ) receptors Angiotensin 2 acts on AT1 receptors found in the endothelium of arterioles throughout the circulation to achieve vasoconstriction. This signalling occurs via a Gq protein, to activate phospholipase C and subsequently increase intracellular calcium Conversion of Aβ43 to Aβ40 by the successive action of angiotensin-converting enzyme 2 and angiotensin-converting enzyme.

Neurohumoral activation, in particular, of the renin-angiotensinaldosterone system (RAAS) and the sympathetic nervous system, plays a major role in the development and progression of HF. 1,2 The RAAS is an essential component in the regulation of cardiovascular homeostasis that exerts its actions through the hormones angiotensin II and aldosterone The only angiotensin receptor blocker (ARB) for first-line treatment of hypertension in cats. Because ARBs feature a unique, targeted mode of action that specifically blocks the harmful vasoconstrictive effects of the renin-angiotensin-aldosterone system (RAAS), SEMINTRA is shown to quickly lower blood pressure within 14 days‡


Mechanism of Action. Angiotensin II causes direct vasoconstriction of precapillary arterioles and postcapillary venules, inhibits the reuptake of norepinephrine, stimulates the release of catecholamines from the adrenal medulla, reduces urinary excretion of sodium and water, stimulates synthesis and release of aldosterone, and stimulates. The renin-angiotensin system or RAS regulates blood pressure and fluid balance in the body. When blood volume or sodium levels in the body are low, or blood potassium is high, cells in the kidney release the enzyme, renin. Renin converts angiotensinogen, which is produced in the liver, to the hormone angiotensin I.. Central Actions of Angiotensin and Related Hormones investigates the centrally mediated actions of angiotensin and related hormones in the central nervous system (CNS). Topics covered include angiotensin I converting enzyme activity in the choroid plexus and in the retina; peptide regulation of neuronal excitability; effects of angiotensin-II.

Angiotensin (AT 1) receptor antagonists are a new class of drugs for the treatment of hypertension. 1 Like ACE inhibitors, they block the renin angiotensin system, but at a different step. Physiology. The renin angiotensin system (RAS) is a bioenzymatic cascade which results in the formation of the vasoactive peptide angiotensin II (Fig. 1) ACE inhibitor and bradykinin. Angiotensin-converting enzyme (ACE) is an enzyme that breaks down and inactivates bradykinin 10). ACE is present in the lungs and the kidneys and also converts angiotensin 1 to angiotensin 2. This conversion is a crucial step in blood pressure control as angiotensin II causes vasoconstriction and increases blood. Angiotensin-I converting enzyme (ACE) is a two-domain dipeptidylcarboxypeptidase involved in regulating blood pressure via the kallikrein-kininand renin-angiotensin-aldosterone complex. Therefore, ACE is a key drug target for the treatment of cardiovascular system diseases. At present many works are focus on searching for new inhibitory peptides of ACE to control the blood pressure Recently available information on the occurrence of angiotensin II type 2 receptors (AT2Rs) within or adjacent to brain cardiovascular control centers is consistent with findings that stimulation of these receptors lowers BP, particularly during hypertension of neurogenic origin The actions of angiotensin II are mediated by receptor AT 1, which triggers detrimental effects, and AT 2, which triggers some beneficial effects
