Objective To observe the protective effect of fasudil hydrochloride against myocardial ischemia/reperfusion injury in patients undergoing mitral valve replacement (MVR). Methods Forty patients who received MVR surgery were randomly divided into two groups: treatment group (T group, 20 cases, fasudil hydrochloride, 1 mg/kg) and control group (C group, 20 cases, normal saline). The concentrations of lactate dehydrogenase (LDH), Creatine kinase isoenzyme MB (CK-MB), and Cardiac troponin I (cTnI) in plasma were recorded and analyzed after induction of anesthesia (T1) and at 5 time points after cardiopulmonary bypass (CPB, T2-T5). Myocardial samples were selected to detect cell apoptosis rate. Results After CPB, LDH (U/L) in T group was significantly lower than in C group at T4 and T5 (486.05±39.52 vs. 528.13±47.65; 551.80±35.43 vs. 593.88±48.89; P<0.01). CK-MB (U/L) in T group was significantly lower than in C group at T3, T4, and T5 (78.39±8.27 vs.88.68±16.18, P<0.05; 62.46±6.10 vs. 72.37±11.85, P<0.01; 47.81±8.19 vs. 54.56±9.21, P<0.05). CTnI (μg/L) in T group was significantly lower than in C group at T3, T4, and T5 (4.40±1.12 vs. 5.80±1.51, 4.93±1.23 vs. 6.49±1.62, 3.99±1.20 vs. 5.80±1.30, P<0.01). The apoptosis rate of cardiomyocytes in T group was significantly lower than in C group [(7.48±2.18)% vs. (12.73±2.74)%, P<0.01]. Conclusion For patients undergoing MVR surgery with CPB, fasudil hydrochloride can decrease the levels of LDH, CK-MB and cTnI in plasma, inhibit apoptosis of cardiomyocytes and relieve myocardial ischemia/reperfusion injury, exerting the protective effects on myocardia. In the experiment, the researchers used many compounds, for example, 5-((1,4-Diazepan-1-yl)sulfonyl)isoquinoline hydrochloride (cas: 105628-07-7Safety of 5-((1,4-Diazepan-1-yl)sulfonyl)isoquinoline hydrochloride).
5-((1,4-Diazepan-1-yl)sulfonyl)isoquinoline hydrochloride (cas: 105628-07-7) belongs to isoquinoline derivatives. Quinoline is a catabolite of tryptophan, the basic structure of some antihypertensive drugs, such as the peripheral vasodilators prazosin and doxazosin. They are also used to make oil-soluble dyes, food colorants, pharmaceuticals, pH indicators and other organic compounds. Safety of 5-((1,4-Diazepan-1-yl)sulfonyl)isoquinoline hydrochloride
