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。
Metaraminol hydrochloride, used primarily as a vasoconstrictor in the treatment of HYPOTENSION, is a sympathomimetic agent that acts predominantly at alpha-1 adrenergic receptors.
Endothelin 1 (swine, human), a synthetic peptide mirroring the sequence of both human and swine Endothelin 1, functions as a robust endogenous vasoconstrictor by interacting with two receptor types, ETA and ETB.
PD 109488 is a metabolite of quinapril and is a derivative of Quinapril that acts as an ACE inhibitor. Inhibition of ACE prevents the conversion of signaling peptide angiotensin I into angiotensin II, which acts as a potent vasoconstrictor. Reduced levels of angiotensin II also reduces the amount of aldosterone that is expressed due to RAAS signaling.
