Metabolite Identification
Common NameTemocapril
DescriptionTemocapril belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Temocapril is a very strong basic compound (based on its pKa). In humans, temocapril is involved in temocapril metabolism pathway. Temocapril can also be used in hemodialysis patients without risk of serious accumulation. When compared with other Angiotensin-converting Enzyme Inhibitors, temocapril's advantages include a rapid onset of action and what research suggests is tighter vascular ACE binding than enalaprilat. ACE inhibitors exert their hemodynamic effect mainly by inhibiting the renin-angiotensin system. Temocaprilat has slightly higher potency than enalaprilat in ACE inhibition isolated from rabbit lung. Temocapril is a prodrug-type angiotensin-I converting enzyme (ACE) inhibitor not approved for use in the United States, but is approved in Japan and South Korea. Temocapril is a prodrug of its active metabolite (and diacid form) temocaprilat which contains a thiazepine ring. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis.
