Abstract:
PROBLEM TO BE SOLVED: To obtain a substituted cinnamoyl guanidide useful as a therapeutic or diagnostic agent for cardiovascular diseases such as arrhythmia, myocardial infarction and stenocardia. SOLUTION: This substituted compound (salt) is expressed by formula I [R(1)-R(5) (X is CR(16), O, S, etc.; R(16) is H, a 1-4C alkyl, etc.; Y is a 1-8C alkylene, etc.; L is O, S, etc.; U is NR(24)R(25), N-contg. heterocycle, etc.; R(24) and R(25) are each H, a 1-4C alkyl, etc.; (a), (b) and (n) are each 0 or 1; R(6) and R(7) are each H, Cl, Br, I, CN, a 1-8C alkyl, etc.]. This compound is obtained by reaction of a compound of formula II (L is a nucleophilically substituent eliminable group) with guanidine. This compound of formula I is e.g. E-3-(4- dimethylaminophenyl)-2-methyl-propenoyl guanidide. This compound can be administered orally or parenterally, that is, intravenously, intrarectally or imhaledly, its dose being 0.1-10mg/kg.
Abstract:
The active substances identified as inhibitors of the cellular Na+/H+ exchanger (NHE) are used to prepare a medicament for normalizing serum lipids. They are used in the preparation of a medicament which reduces lipid levels in the blood and can be administered for treating diseases caused by lipid levels which are too high, and for alleviating the endothelial dysfunctional syndrome and for treating diseases caused thereby.

Abstract:
PROBLEM TO BE SOLVED: To provide an intermediate compound for producing a diacyl- substituted guanidine useful as a Na+/H+ exchange inhibitor. SOLUTION: This intermediate compound is a compound of the formula III [wherein, X(2) is a group as shown in the formula (a)]. As an example of the compound of the formula III, 4-isopropyl-3-methylsulfonylbenzoylguanidine and 4-fluoro-3-trifluoromethylbenzoylguanidine are cited. As the method for producing them, a method of reacting an acid chloride of a corresponding benzoic acid with guanidine hydrochloride in the presence of a base is exemplified. The diacylguanidine used as a medicine is obtained by reacting the compound of the formula III with a prescribed benzoic acid derivative.
Abstract:
Monoacyl - substituted guanidines of the formula III (see formula III) are described where X(2) is (see formula I) as are the pharmaceutically tolerated salts thereof. They are outstandingly suitable for use as antiarrhythmic pharmaceuticals possessing a cardioprotective component for the prophylaxis and treatment of infarction and for the treatment of angina pectoris, in connection with which they also inhibit or strongly reduce, in a preventive manner, the pathophysiological processes associated with the genesis of ischemically induced damage, in particular associated with the elicitation of ischemically induced cardiac arrhythmias. On account of their protective effects against pathological hypoxic and ischemic situations, the compounds of the formula I according to the invention can, as a consequence of inhibiting the cellular Na+/H+ exchange mechanism, be used as pharmaceuticals for treating all acute or chronic damage eliciated by ischemia, or diseases induced primarily or secondarily thereby.
Abstract:
Phenyl-substituted alkenylcarboguanidides carrying perfluoroalkyl groups, of the formula I (see Formula I) in which the substituents have the meanings stated in the description, and their pharmaceutically suitable salts, are described. They are obtained by reacting a compound II (see Formula II) with guanidine, in which R(1) to R(5) and R(A), R(B), R(C) and R(D) have the stated meaning, and L is a leaving group which easily undergoes nucleophilic substitution. Compounds I are excellent cardiovascular therapeutic agents.
Abstract:
Ortho-substituted benzoylguanidines of the formula I in which R(1) to R(5) have the meanings given in the claims, are suitable as antiarrhythmic pharmaceuticals having a cardioprotective component for infarct prophylaxis and for infarct treatment and also for the treatment of angina pectoris. They also inhibit in a preventive manner the pathophysiological processes in the formation of ischemically induced damage, in particular in the illicitation of ischemically induced cardiac arrhythmias.
