Description:
FIELD OF THE INVENTION 
     The present invention relates to the organic chemistry and, more specifically, to novel substituted 3-hydrazinopropionates possessing an antiarrhythmic activity and useful in medicine for the treatment of the heart beat disturbances. 
     BACKGROUND OF THE INVENTION 
     Known in the art is rather wide range of a biological effect of close structural analogs of the compounds according to the present invention--hydrazides, semicarbazides, thiosemicarbazides. Thus, among these compounds there are antibacterial preparations known in the treatment of tuberculosis, monoaminooxydase inhibitors, analgetics, diuretics (cf. Mashkovsky M.D., Pharmaceutical Preparations, &#34;Medicina&#34; Publishing House, part 1, II, 1977). However, the literature fails to submit information to the effect that these compounds having such structure possess an antiarrhythmic activity. 
     The closest chemical structure is inherent in 1,1-dimethyl-2-methylcarbamoyl-2-(γ-phenylamyl)hydrazine, but no data on its biological activity are available in the literature (cf. K. Chantrapromma, W. D. Ollis, J. O. Sutherland, The thermal rearrangement of allyl- and pentadienyl-ammonioamidates. Evidence for competing but distinct concerted and radical mechanisms., J.Chem.Soc., Chem.Commun., 1977, (3), (97-99). 
     The antiarrhythmic preparations currently employed in medicine--procaine amide and quinidine feature a high acute toxicity and bring about a number of negative side effects. 
     The present invention is directed to the provision of novel substituted 3-hydrazinopropionates possessing a high antiarrhythmic activity and a low toxicity. 
     The compounds according to the present invention are novel and hitherto unknown from the literature. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide such novel substituted 3-hydrazinopropionates which would feature a high antiarrhythmic activity and a low toxicity. 
     These and other objects of the present invention are accomplished by such substituted 3-hydrazinopropionates which comprise compounds of the general formula: ##STR3## wherein R 1 , R 2  =H, an alkyl, a substituted alkyl, hydroxycarbonyl, an alkoxycarbonyl, an aryl, an aralkyl, an unsaturated alkyl, a substituted aryl, or a substituted aralkyl; ##STR4## wherein R 7 , R 8  =H, an alkyl, an unsaturated alkyl, an aralkyl, an aryl, a substituted alkyl; 
     R 9  is OH, an alkoxy, an aralkoxy, an alkyl, an unsaturated alkyl, an aryl, a substituted aryl, an aralkyl; 
     R 4  =-C≳N, --COR 10 , wherein R 10  =OR 11 , NR 12  R 13 , where R 11  is H, an alkyl, an aralkyl, an alkali metal; R 12 , R 13  are each H, an alkyl, an aralkyl, an aryl; R 5  and R 6  are an alkyl, an aryl, an aralkyl. 
     DETAILED DESCRIPTION OF THE INVENTION 
     Physico-chemical constants of the compounds according to the present invention are shown in Table 1. 
     The structure of substituted 3-hydrazinopropionates is justified by the data of elemental analysis (Table 2) and spectra of proton magnetic resonance (PMR) /Table 3/. 
     It is advisable to use substituted 3-hydrazinopropionates of the general formula: ##STR5## wherein in R 3  = ##STR6## 
     The study of the effect provided by the compounds according to the present invention on the cardio-vascular system was carried out in experiments on white mice. The specific (antiarrhythmic) effect and acute toxicity were studied. For the purpose of comparison known antiarrhythmic preparations--procaine amide and quinidine were used. 
     The antiarrhythmic activity of the compounds according to the present invention was studied on a model of arrhythmia induced by an intravenous administration of calcium chloride. In experiments on white mice of both sexes with a mass of 18-25 g narcotized by urethane (1,200 mg/kg intraperitoneally) ECG in the second standard lead was recorded. A 2% solution of calcium chloride was introduced into the tail vein at a constant rate (0.01 ml for 2 sec). The dose of calcium chloride causing arrhythmia and the dose causing the heart arrest were determined. In the test groups the test compounds were administered intraperitoneally 20-40 minutes before the beginning of the experiment. The results thus obtained are given in Table 4. 
     As it follows from the data of the above Table 4, the compounds according to the present invention possess the antiarrhythmic activity comparable with that of highly effective clinical preparations--quinidine and procaine amide. 
     The acute toxicity of the compounds according to the present invention was determined in experiments on white mice with a mass of 20-25 g. The test compounds were administered intraperitoneally in the form of aqueous solutions or suspensions in Twin-80. Observation over the test animals was effected for 10 days. The results thus obtained are shown in Table 5. It has been found that the compounds according to the present invention are low-toxic. As compared to quinidine they have a substantially lower toxicity which is demonstrated by high figures of the relative toxicity (Table 5). 
     Therefore, it has been found that the compounds according to the present invention possess a considerable antiarrhythmic activity and a substantially lower toxicity which distinguishes them favourably from the known preparations. This enables a suggestion that the compounds according to the present invention will be useful in medicine. 
     The method for the preparation of substituted 3-hydrazino propionates is rather simple. 
     The compounds according to the present invention are produced by a known procedure by reacting substituted 3-(2,2-disubstituted hydrazino)propionates with isocyanates, isothiocyanates or acylation agents. If it is necessary to introduce an amide grouping, the compounds produced by the above-mentioned reactions are subjected to ammonolysis; when required to obtain free acids or salts thereof, these compounds are subjected to hydrolysis.
