Angiotensin II 是一种主要的生物活性血管收缩肽,通过与AT1R和AT2R受体结合,调节血压,刺激交感神经,促进醛固酮合成和肾脏功能。它还能诱导血管平滑肌细胞增生、胶原合成增加,导致血管和心肌增厚及纤维化,同时促进细胞凋亡和内皮细胞毛细血管形成。Angiotensin II常用于诱导高血压和心脏肥大动物模型。
Angiotensin II human acetate 是肾素-血管紧张素系统中的主要血管收缩肽,通过与AT1R和AT2R受体结合调节血压,刺激交感神经,促进醛固酮合成和肾脏功能,诱导血管平滑肌细胞增生和胶原合成,导致血管及心肌增厚和纤维化,同时促进细胞凋亡和内皮毛细血管形成。常用于诱导高血压和心脏肥大模型。
Methyl-2-[(6Z,9Z)-6,9-pentadecadienyl]-4(1H)-quinolone9, a quinolone alkaloid derived from Evodia rutaecarpa, is a potent antagonist of the angiotensin II receptor, displaying an IC50 value of 48.2 μM.
BIBS-222, a nonpeptide angiotensin II (Ang II) receptor antagonist, appears to be an effective antihypertensive in the model of the renal hypertensive rat.
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.
