| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| Description | Quinapril is a prodrug that belongs to the angiotensin-converting enzyme (ACE) inhibitor class of medications.
Target: ACE
Quinapril is an angiotensin-converting enzyme inhibitor (ACE inhibitor) used in the treatment of hypertension and congestive heart failure. Quinapril is rapidly de-esterified after absorption to quinaprilat (the active diacid metabolite), a potent angiotensin converting enzyme (ACE) inhibitor. Quinapril is now firmly established as an effective and well tolerated ACE inhibitor for the treatment of patients with hypertension and congestive heart failure. Quinapril 40 mg/day also significantly reduced the incidence of ischaemic events in patients undergoing CABG in one study [1, 2]. An overview of 32 clinical trials of ACE inhibitors in heart failure showed that no significant heterogeneity in mortality was found among enalapril, ramipril, quinapril, captopril, lisinopril, benazepril, perindopril and cilazapril. Initiation of therapy with captopril, ramipril, and trandolapril at least 3 days after an acute MI resulted in all-cause mortality risk reductions of 18 to 27% [3]. References: | |||||

[Antihypertensive activity of the angiotensin converting enzyme inhibitor quinapril HCl: (S)-2-[(S)-N-[(S)-1-ethoxycarbonyl-3-phenylpropyl) alanyl]-1,2,3,4- tetrahydro-3-isoquinolinecarboxylic acid monohydrochloride in various hypertensive animal models].[Pubmed:8335286]
Nihon Yakurigaku Zasshi. 1993 Jul;102(1):35-45.
The antihypertensive activity of quinapril was examined in normotensive and various hypertensive animal models. In 2-kidney, 1-clip renal hypertensive rats (2K-RHR), quinapril (0.1 to 1.0 mg/kg, p.o.) had a dose-related and sustained antihypertensive action, which was as potent as that of enalapril and approximately 40 times stronger than that of captopril. Heart rate was not changed by these doses of quinapril. In spontaneously hypertensive rats (SHR) and 1-kidney, 1-clip renal hypertensive rats, quinapril as well as enalapril dose-dependently produced a significant fall in blood pressure. The relative potency and duration of the effect of quinapril was the same as that of enalapril in these models. Quinapril at 30 mg/kg, p.o. lowered blood pressure and increased heart rate in normotensive rats. In contrast, quinapril and enalapril failed to reduce blood pressure in DOCA/salt hypertensive rats. In the repeated dose study, no development of tolerance was observed during the administration period in 2K RHR and SHR. The antihypertensive effects in 2K RHR was greater than those in SHR. Quinapril was more potent and long-lasting than enalapril in 2K RHR and SHR. From these results, quinapril is expected to be useful for the clinical treatment of hypertension.
