RESUMO
The syntheses of salts [III, IV] and amides [V, V.HCl] of 2-[5-chloro-4-methyl-2-[(5-amino-s-triazol-3-yl)aminosulphonyl+ ++] phenylthio] alkanoic acids, as well as 5-amino-2-[2-(2,4-dimethylpiperidino) ethyl]-3-[4-chloro-2-[2-(2,6-dimethylpiperidino) ethylthio]-5-methylbenzenesulphonylimino]-1-methyl-delta 4-1,2,4-triazoline dihydrochloride [X] and 5-(amino-, 4-chloroanilino- or 3,4,5-trimethoxyanilino)-1,2-di[2-(2,6-dimethylpiperidino) ethyl]-3-(4-chloro-2-[2-(2,6-dimethylpiperidino) ethylthio]-5-methylbenzenesulphonylimino)-delta 4-1,2,4-triazoline trihydrochlorides [XI-XIII] are described. The results of preliminary pharmacological examinations such as acute toxicity and influence on circulatory system of compounds III, IV, V.HCl and X-XIII are presented. The antiarrhythmic effect of the most active [XI] was stronger or comparable to the reference drugs quinidine and procainamide.
