Benzoylguanidines of the formula I ##STR1## are described where R(1) is R(4)--SO.sub.m or R(5)R(6)N--SO.sub.z --, where R(4) and R(5) are alk(en)yl or --C.sub.n H.sub.2n --R(7), and where R(7) is a cycloalkyl or phenyl, where R(5) also has the meaning of H, and R(6) is H or C.sub.1 -C.sub.4 -alkyl, R(2) is hydrogen, halogen, alkyl, O--(CH.sub.2).sub.m C.sub.p F.sub.2p+1, --X--R(10), where X is O, S or NR(11), R(10) is H, (cyclo)alkyl(methyl) or --C.sub.n H.sub.2n --R(12) where R(12) is phenyl, and R(3) is defined, inter alia, as R(1), and their pharmaceutically tolerable salts. The compounds I are obtained by reaction of compounds of the formula II ##STR2## with guanidine, in which L is a leaving group which can be easily nucleophilically substituted. Compounds I are outstandingly suitable as antiarrythmic pharmaceuticals having a cardioprotective component for infarct prophylaxis and infarct treatment and for the treatment of angina pectoris, where they also preventively inhibit or greatly reduce the pathophysiological processes during the formation of ischemically induced damage. They are moreover distinguished by strong inhibitory action on the proliferation of cells. They can therefore be used as antiatherosclerotics, agents against late-onset diabetic complications, cancers, and fibrotic diseases such as pulmonary fibrosis, fibrosis of the liver or fibrosis of the kidneys. They are effective inhibitors of the cellular sodium/proton antiporter (Na.sup.+ /H.sup.+ exchanger).
描述了化学式I的苯甲酰胍,其中R(1)为R(4)--SO.sub.m或R(5)R(6)N--SO.sub.z --,其中R(4)和R(5)为烷基或--C.sub.n H.sub.2n --R(7),R(7)为环烷基或苯基,其中R(5)也表示H,R(6)为H或C.sub.1 -C.sub.4 -烷基,R(2)为氢、卤素、烷基、O--(CH.sub.2).sub.m C.sub.p F.sub.2p+1、--X--R(10),其中X为O、S或NR(11),R(10)为H、(环)烷基(甲基)或--C.sub.n H.sub.2n --R(12),其中R(12)为苯基,R(3)被定义为R(1),以及它们的药物耐受性盐。化合物I是通过化合物II与胍反应得到的,其中L是易于亲核取代的离去基团。化合物I非常适用作为抗心律失常药物,具有心脏保护成分,用于梗死预防和梗死治疗以及心绞痛治疗,它们还可以预防性地抑制或大幅减少缺血性损伤形成期间的病理生理过程。此外,它们还具有强烈的细胞增殖抑制作用。因此,它们可用作抗动脉粥样硬化药物、晚发型糖尿病并发症、癌症以及肺纤维化、肝脏纤维化或肾脏纤维化等纤维化疾病的药物。它们是细胞钠/质子抗转运蛋白(Na.sup.+ /H.sup.+交换体)的有效抑制剂。
