The present invention is related to benzothiophen-2-carbonylguanidine derivatives, a preparation method thereof, and pharmaceutical compositions containing the same. The derivatives have potent inhibitory effect on the sodium/hydrogen exchanger NHE-I, improve the functional recovery of ischemia/reperfusion-induced heart injury in isolated ischemic heart models, and significantly reduce the myocardiac infarct size in in vivo ischemic animal models, thereby showing excellent cardioprotective effects. Also, the derivatives are protective of both neuronal cells and the brain as proven by their protective effects on neuronal cells from necrosis and apoptosis and by their ability to significantly reduce cerebral infarct sizes in in vivo ischemic brain models. The derivatives can be effectively used for the prevention and treatment of ischemic heart diseases such as myocardiac infarction, arrhythmia, angina pectoris and the like, and cerebrovascular diseases such as cerebral stroke and be used as cardioprotective agents to the patients undergoing reperfusion therapy including chemicals such as thrombolytic agents, or surgery such as coronary artery bypass and percutaneous transluminal coronary angioplasty.
本发明涉及苯并噻吩-2-羧酰基胍衍生物、其制备方法以及含有其的制药组合物。这些衍生物对钠/氢交换NHE-I具有强效的抑制作用,在离体缺血心脏模型中提高了缺血/再灌注所致的心脏损伤的功能恢复,并在体内缺血动物模型中显著减少心肌梗死面积,因此表现出优异的心脏保护作用。此外,这些衍生物通过对神经元细胞的保护作用和在体内缺血脑模型中显著减少脑梗死面积的能力,也能保护神经元和大脑。这些衍生物可有效用于预防和治疗缺血性心脏疾病,如心肌梗死、心律失常、心绞痛等,以及脑血管疾病,如脑卒中,并可用作心脏保护剂,用于接受再灌注治疗的患者,包括使用溶栓剂等化学药物或手术,如冠状动脉旁路移植术和经皮冠状动脉成形术。
