Temocapril 

Temocapril is an orally active angiotensin-converting enzyme (ACE) inhibitor. Temocapril can be used for the research of hypertension, congestive heart failure, acute myocardial infarction, insulin resistance, and renal diseases^[1][2].

Angiotensin-converting Enzyme (ACE)^[1]

Temocapril hydrochloride is a prodrug of the ACE inhibitor, Temocaprilat. Temocapril hydrochloride can be readily uptaken via the small intestine, and then be converted to its active metabolite (temocaprilat) by CES1 (human carboxylesterase 1) in the liver^[1].
Temocapril hydrochloride (500 nM) reduces the inhibitory effects of RS (N-acetyltetradecapeptide renin substrate) and AngI (angiotensin) on neurogenic vasodilation in the spontaneously hypertensive rats (SHR)^[2].
Temocapril hydrochloride (0.1-10 μM; 24 h) shows inductive effects on redox proteins thioredoxin (TRX) while no effect on antioxidant enzymes Cu/ZnSOD and Mn-SOD expressions^[3].

Temocapril (10 mg/kg; p.o.; 21 d) enhances cardiomyocyte thioredoxin expression and ameliorates autoimmune myocarditis^[3].
Temocapril (30 mg/kg; p.o.; daily; for 4 weeks) suppresses Angiotensin I-induced hypertension, plasma and renal ACE activity, but fails to reduce the level of Ang II in the kidney^[4].
