Biological Activity

[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].
