Spirapril  (Synonyms: SCH 33844)

Spirapril is a potent and cross the blood-brain barrier angiotensin converting enzyme (ACE) inhibitor with antihypertensive activity. Spirapril competitively binds to ACE and prevents the conversion of angiotensin I to angiotensin II. Spirapril is an orally active proagent of Spiraprilat and can be used for the research of hypertension, congestive heart failure^[1][2][3].

Spirapril (feeding needle; 10 mg/kg; 3 weeks) decreases alcohol intake in TGM123 mice and dose not reduce the alcohol consumption in TLM mice^[2].
Spirapril shows a 40.2% reduction in ACE activity in brain membrane from treated-mice^[2].
Spirapril can crosses the blood-brain barrier and suppresses the transgene effect in the experiments^[2].
Spirapril prevents left ventricular hypertrophy, decreases myocardial damage and promotes angiogenesis in spontaneously hypertensive rats^[3].
