Moexipril-d₃ 

Moexipril-d₃ is deuterated labeled Moexipril (HY-117281). Moexipril is an orally active inhibitor of angiotensin-converting enzyme (ACE), and becomes effective by being hydrolyzed to moexiprila hydrochloride. Moexipril exhibits antihypertensive and neuroprotective effects^[1]-[4].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
Moexipril is devoid of anti-inflammatory properties and has no effect on platelet function^[3].
Moexipril hydrolyzes to Moexiprilat, and Moexiprilat inhibits ACE in guinea pig serum as well as on purified ACE from rabbit lung with IC₅₀s of 2.6 nM and 4.9 nM, respectively^[3].
Moexipril (0.01 nM-0.1 mM) exhibits high potency against both ACE in rats plasma and purified ACE from rabbit lung, with IC₅₀s of 1.75 nM and 2.1 nM, respectively^[4].
Moexipril (0-100 μM, 24 h) significantly reduced the percentage of damaged neurons in a dose-dependent manner^[5].
Moexipril (0-100 μM, 24 h) significantly attenuates Fe^2+/3+-induced neurotoxicity^[5].
Moexipril dose not cause significant changes in the percentage of apoptotic neurons^[5].

Moexipril can not cross the blood-brain barrier^[2].
Moexipril (3 mg/kg, 30 mg/kg and 10 mg/kg; p.o.; once daily; 5 days) exhibits a dose-dependent and antihypertensive effects in renal hypertensive rats, spontaneously hypertensive rats and perinephritic hypertensive dogs, respectively^[4].
Moexipril (0.3 mg/kg, i.p.) significantly reduces the infarct area on the mouse brain surface in NMRI mice^[5].
Moexipril (0.1 mg/kg, i.p.) significantly attenuates the cortical infarct volume in Long-Evans rats^[5].
