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。
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.
