描述 | Angiotensin-converting enzyme (ACE) is responsible for the conversion of angiotensin I (ATI) to angiotensin II (ATII), which regulates blood pressure and is a key component of the renin-angiotensin-aldosterone system (RAAS) [3]. Lisinopril (MK-521) is angiotensin-converting enzyme inhibitor with inhibition constant (Ki) value of 0.39 mM, used in treatment of hypertension, congestive heart failure, and heart attacks[4]. Although lisinopril significantly reduced preload, its effect on left ventricular (LV) contractility was insignificant in experimental mitral regurgitation (MR). Conversely, atenolol, when added to lisinopril, achieved maximum hemodynamic benefit and also restored LV contractility [5]. In spontaneously hypertensive rats (SHR) rats, levels of α-tocopherol were substantially reduced in both plasma and cardiac tissue. Treatment with lisinopril ameliorated reduced levels of plasma α-tocopherol in SHR rats [6]. Paraquat caused a significant increase in hydroxyproline content and lisinopril significantly decreased the amount hydroxyproline (p<0.001) in the lung tissue of the rats. The histological examination also indicated that lisinopril can effectively protect the paraquat-induced lung fibrosis [7]. In isolated guinea pig hearts, lisinopril protects the cell membrane integrity and lessens free radical-induced oxidant stress [8]. |
