ABSTRACT
The NMR spectroscopy has advantages over other techniques in studying the structure, kinetics and thermodynamics of rapid processes, complex formation and metabolism reactions in the solution. NMR is used for investigating the structure of biologically active substances and drugs, the mechanism of their action as it permits the establishment of chemical shifts of single nuclei in the molecule, the constants of spin-spin interaction, the time of relaxation.

The effects of potassium malate and sodium succinate on the antiarrhythmic activity of novocainamide and acetylnovocainamide during modelling of chlor-calcium-induced arrhythmia as well as in disorders of cardiac rhythm during modelling of pituitrin-isadrine-induced myocardial infarction were studied. The metabolic agents were found to increase the effectiveness of acetylnovocainamide and the toxicity of novocainamide. To interpret the specific features of the mechanism of the anti-arrhythmic action of the compounds there was studied their ability to form complexes with components of biomembranes and ions of biometals.
