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 I/II (1-6) TFA is a chemical compound comprising amino acids 1-6. It is derived from the Angiotensin I/II peptide, which is formed by the cleavage of the precursor angiotensinogen by renin. The resulting Angiotensin I is then hydrolyzed by angiotensin-converting enzyme (ACE) to produce biologically active Angiotensin II. Angiotensin II has been extensively studied for its potential applications in the treatment of Hypertension, Renin Angiotensin System, and Idiopathic Membranous Nephropathy[1][2][3].
[Tyr(P)4] Angiotensin II is a peptide that exerts a multitude of effects on vascular smooth muscle. These effects include the contraction of normal arteries, as well as the induction of hypertrophy or hyperplasia in cultured cells or diseased vessels.
Angiotensin II human TFA 是肾素-血管紧张素系统中的强效血管收缩剂,通过与 AT1R 和 AT2R 受体作用调节血压,可激活交感神经、促进醛固酮合成和肾功能,诱导血管平滑肌细胞增殖及成纤维细胞中 I 型和 III 型胶原合成,导致血管和心肌增厚、纤维化,并诱导凋亡及促进毛细血管生成,可用于构建心脏肥大、高血压和腹主动脉瘤模型。
[Sar1, Ile8]-Angiotensin II (TFA) is a peptide compound that exerts various effects on vascular smooth muscle. These effects include the contraction of normal arteries as well as the hypertrophy or hyperplasia of cultured cells or diseased vessels.
Angiotensin II is a potent direct vasoconstrictor, causing arteries and veins to constrict, so leading to an increase in blood pressure. Angiotensin also potentiates the release of norepinephrine by a direct action on postganglionic sympathetic fibers.
