生物活性：Moveltipril calcium (MC-838 calcium)是一种口服活性血管紧张素转化酶（ACE）抑制剂，具有抗高血压活性。Moveltipril calcium通过稳定的硫酯键结合，表现出相对抵抗大鼠肝匀浆的酶解。Moveltipril calcium在浓度依赖 manner下有效抑制从兔肺提取的ACE。Moveltipril calcium能够在游离大鼠主动脉环和豚鼠回肠制备中高度特异性地抑制对血管紧张素-I（A-I）的收缩反应，同时增强对降钙素的收缩反应。

Moveltipril calcium (MC-838 calcium) is an orally active angiotensin converting enzyme (ACE) inhibitor with antihypertensive activity. Moveltipril calcium binds via a stable thioester bond and exhibits relative resistance to enzymatic hydrolysis in rat liver homogenate. Moveltipril calcium effectively inhibits ACE extracted from rabbit lung in a concentration-dependent manner. Moveltipril calcium is able to highly specifically inhibit the contractile response to angiotensin-I (AI) in free rat aortic rings and guinea pig ileum preparations, while enhancing the contractile response to calcitonin^[1].
