[Comparative study of the toxicity and antiarrhythmic activity of some organic derivatives of dimethylacetamide].

A comparative study of the acute toxicity and antiarrhythmic activity of new domestic derivatives of dimethylacetamide showed that the introduction of amino and carboxylic acid residues into the structure of compounds is accompanied by reduction of the toxic properties of new substances on the average 2.73 times (p = 0.002) upon intraperitoneal introduction to animals.
