Angiotensin II human acetate (DRVYIHPF acetate) 是血管收缩剂,是肾素 血管紧张素系统的主要生物活性肽,在调节人类血压中起着核心作用。它刺激交感神经刺激,增加醛固酮生物合成和肾脏活动。它诱导血管平滑肌细胞生长,也诱导细胞凋亡。它通过 LOX-1 依赖的氧化还原敏感途径诱导内皮细胞毛细血管形成。
EC33, a selective aminopeptidase A (APA) inhibitor, blocks the pressor response of exogenous AngII and does not cross the blood-brain barrier, making it a potential candidate for salt-dependent hypertension research [1].
BIBS-222, a nonpeptide angiotensin II (AngII) receptor antagonist, appears to be an effective antihypertensive in the model of the renal hypertensive rat.
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.
Atrial Natriuretic Peptide (ANP) (1-28), rat (TFA), is the primary circulating form of ANP in rats and significantly inhibits AngII-stimulated secretion of endothelin-1.
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 AngII (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.
