angiotensin (1 7)

Angiotensin (1-7) (ASP-ARG-VAL-TYR-ILE-HIS-PRO) 是肾素-血管紧张素系统中的内源性七肽。Angiotensin 1-7在心肌细胞中具有抗炎和抗纤维化活性，因此具有心脏保护作用。它能抑制血管紧张素转换酶和释放一氧化氮，是激肽诱导的血管舒张的局部协同调节剂。它阻断 Ang II 诱导的平滑肌细胞增殖和肥大，并显示对内皮的抗血管生成和生长抑制作用。它显示出抗炎活性。

Angiotensin 1/2 (5-7) acetate 是一种具有 H2N-Ile-His-Pro-OH 序列的肽。血管紧张素是一种寡肽，是一种激素和一种强大的双肽原。它来源于前体分子血管紧张素原，一种在肝脏中产生的血清球蛋白。它在肾素-血管紧张素系统中起重要作用。

Angiotensin (1-7) acetate (Ang-(1-7) acetate) 是存在于血管紧张素中的一段氨基酸序列，具有抗纤维化和心脏保护作用，抑制纯化的犬血管紧张素转换酶 (ACE) 活性。Angiotensin (1-7) acetate 抑制肿瘤细胞的生长并减少几种类型癌症的局部炎症和血管生成，阻断血管紧张素 Ⅱ 诱导的平滑肌细胞增殖和肥大，可用于研究动脉粥样硬化和新型冠状病毒感染。

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.

Aclerastide is an angiotensin receptor agonist. Administration of Aclerastide reduced fibrosis and scarring in the healing wounds. This action was more pronounced with longer administration of the peptide after injury. The action of this peptide was block
