The compounds of the above formula and their pharmaceutically acceptable acid addition salts are distinguished by interesting pharmacological properties and possess, in particular, heart rhythm-enhancing activity and high physiological compatibility. So, in small doses have a satisfactory antiarrhythmic effect. In addition, the undesirable negative effect of the contractility of the heart is negligible. Thus, the compounds have a particularly favorable ratio of antiarrhythmic and, respectively, lengthening the refractory phase of the heart, actions to negatively inotropic side effects and have a large therapeutic latitude. The antiarrhythmic effects of the compounds can be proved by standard pharmacological test methods. For example, in the case of a compound, the inhibitory effect is in relation to ventricular fibrillation caused by inhalation of chloroform. The effect of compounds on chloroform-induced inhalation, leading to too rapid respiratory arrest, ventricular fibrillation (flicker) in the case of a smaller one is determined by a known method.
    In this experiment, it is also possible to determine at the same time the minimum toxic dose. The substances are administered to female mice weighing 17-24 g in the form of a 0.9% NaCl solution intraperitoneallyBNO. Animals individually kept in glass cups, where they observe possible toxic symptoms
    Ten minutes after administration of the test substances, the animals are transplanted into closed 300-MP glass beakers, which contain a cotton swab soaked in about 20 ml. Immediately after the onset of cessation of breathing is released
    (open) the heart and visually observe the ventricular rhythm and speed. It is determined what percentage of animals are protected by the administered dose against ventricular fibrillation.
    The compounds in the indicated test at doses in the range of 0-1-100 mg / kg show antiarrhythmic effects. In tab. 2 presents the results obtained by this test method. In addition, the minimum toxic doses for intraperitoneal (i. P.) And oral (p. O.) Administration are indicated.
    Comparative substances, known as good antiarrhythmics, did not show in the range of from about 5% i. R. LDgo significant action and proved to be effective.
