A substituted guanidine derivative represented by the general formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are independently a hydrogen atom, an unsubstituted alkyl group, a substituted alkyl group, a halogen atom or the like; Y.sub.1, Y.sub.2, Y.sub.3, Y.sub.4, Y.sub.5, Y .sub.6 and Y.sub.7, which may be the same or different, are independently a single bond, --CH.sub.2 --, --O--, --CO--or the like, adjacent members of a group consisting of Y.sub.1 through Y.sub.7 being able to be taken together to represent --CH.dbd.CH--, and at least two of Y.sub.1 through Y.sub.7 being independently a group other than a single bond; Z may be absent, or one or more Zs may be present and are, the same or different, independently a substituent for a hydrogen atom bonded to any of the carbon atoms constituting the ring formed by Y.sub.1 through Y.sub.7, for example, an unsubstituted alkyl group or a substituted alkyl group, or a pharmaceutically acceptable acid addition salt thereof, is useful as a therapeutic or prophylactic agent for diseases caused by the acceleration of the sodium/proton (Na.sup.+ /H.sup.+) exchange transport system, for example, hyperpiesia, arrhythmia, angina pectoris, hypercardia, diabetes, organopathies due to ischemia or ischemia re-perfusion, troubles due to cerebral ischemia, diseases caused by cell overproliferations, and diseases caused by trouble with endothelial cells.
一种代表通式的取代胍衍生物:##STR1## 其中,R1、R2、R3和R4独立地表示氢原子、未取代的烷基、取代的烷基、卤素原子或类似物;Y1、Y2、Y3、Y4、Y5、Y6和Y7可以相同也可以不同,独立地表示单键、--CH2--、--O--、--CO--或类似物,由Y1到Y7组成的群体中相邻的成员可以结合在一起表示--CH=CH--,而至少有两个Y1到Y7独立地表示单键以外的群体;Z可以不存在,或者一个或多个Z可以存在,并且可以相同也可以不同,独立地表示取代任何由Y1到Y7形成的环上碳原子的氢原子的取代基,例如未取代的烷基或取代的烷基,或其药学上可接受的酸加成盐,用作由钠/质子(Na+/H+)交换转运系统加速引起的疾病的治疗或预防剂,例如高血压、心律失常、心绞痛、高心率、糖尿病、缺血或再灌注引起的器官病理、脑缺血引起的问题、细胞过度增殖引起的疾病以及内皮细胞问题引起的疾病。
