Metaraminol hydrochloride, used primarily as a vasoconstrictor in the treatment of HYPOTENSION, is a sympathomimetic agent that acts predominantly at alpha-1 adrenergic receptors.
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.
Angiotensin I/II (1-7) amide is a peptide analog to angiotensin II that is used as a vasopressor in the treatment of certain types of shock and circulatory collapse. Angiotensin I/II amide is an amide derivative of angiotensin II that is a powerful vasoco
