Description
Curator's Comment: description was created based on several sources, including https://www.drugbank.ca/drugs/DB01348 | https://www.ncbi.nlm.nih.gov/pubmed/18154140 | https://www.ncbi.nlm.nih.gov/pubmed/15490771 | https://www.ncbi.nlm.nih.gov/pubmed/15752941

Spirapril (Renormax) is an ACE inhibitor antihypertensive drug used to treat hypertension. Spiraprilat, the active metabolite of spirapril, competes with angiotensin I for binding at the angiotensin-converting enzyme, blocking the conversion of angiotensin I to angiotensin II. Inhibition of ACE results in decreased plasma angiotensin II. As angiotensin II is a vasoconstrictor and a negative-feedback mediator for renin activity, lower concentrations result in a decrease in blood pressure and stimulation of baroreceptor reflex mechanisms, which leads to decreased vasopressor activity and to decreased aldosterone secretion. Spiraprilat may also act on kininase II, an enzyme identical to ACE that degrades the vasodilator bradykinin.

Sample Use Guides

The daily dose is 6 mg, the frequency of application is 1 time / day. After 4-6 weeks, in the absence of a satisfactory therapeutic effect, the dose can be increased.
Route of Administration: Oral
Pooled human liver microsomes were obtained from Pfizer Global Supply and the tested compounds were acquired from Pfizer Global Material Management. Each incubation contained tested compounds (Spirapril) (1 mkM), microsomes (0.25 lM protein), NADPH regenerating system (1 mM NADP+, 5 mM isocitric acid and 1 unit/ mL isocitric dehydrogenase), MgCl2 (1 mM) and potassium phosphate buffer (100 mM at pH 7.4). This mixture was incubated at 37 _C for 0, 5, 10, 20, 30 and 60 min before quenching with acetonitrile. Control incubations were prepared using the same procedure without adding the catalytic cofactor NADPH. Individual samples were then analyzed in a ‘trap-and-elute’ mode using LC/MS
