Quinaprilat hydrate is a non-mercapto Angiotensin Converting Enzyme (ACE) inhibitor, the active metabolite of Quinapril. Quinaprilat hydrate specifically blocks the conversion of angiotensin I to the vasoconstrictor angiotensin II and inhibits the degradation of bradykinin. Quinaprilat hydrate acts as anti-hypertensive agent and vasodilator.

Description

Quinaprilat hydrate is a non-mercapto Angiotensin Converting Enzyme (ACE) inhibitor, the active metabolite of Quinapril. Quinaprilat hydrate specifically blocks the conversion of angiotensin I to the vasoconstrictor angiotensin II and inhibits the degradation of bradykinin. Quinaprilat hydrate acts as anti-hypertensive agent and vasodilator[1][2].

In Vitro

Quinaprilat hydrate (5 μM) mediates the interaction of organic anion transporter 3 (hOAT3) which can promote renal active secretion of quinapril that increases uptake of quinaprilat to 25-fold in HEK293 cells and hOAT3 affinity Km for quinaprilat is 13.4 μM[1].
Quinaprilat hydrate (100 nM, 20 min) can inhibit the activity of protein kinase C (PKC) by activing the B1 receptor resulting in the release of NO in human lung microvascular endothelial (HLMVE) cells[2].

In Vivo

Quinaprilat hydrate (oral gavage, 3 mg/kg, every day, 6 days) has some anti-hypertensive effect by combining with other drugs in male spontaneous hypertensive rats (SHRs)[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male spontaneous hypertensive rats (SHRs) (230-250 g)[1]
Dosage: 3 mg/kg
Administration: Oral gavage; every day; 6 days
Result: Caused a significant drop in blood pressure from day 1 to day 5 by combining quinapril and gemcabene while each alone had no effect. Decreased plasma concentration of quinaprilat on the fifth day.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
