title: 2,6-dialkylpiperazines. VIII (1)-N1-arylalkyl-N4-(2'-pyridyl)-2,6-dimethylpiperazines as adrenolytic and vasodilator agents.
abstract: A series of cis and trans N1-arylalkyl-N4-(2'-pyridyl)-2'6-dimethylpiperazines were synthetized and tested as adrenolytic and vasodilator agents. The N1-substitution with the 3,4-dimethoxyphenethyl group seems the most promising with regard to pharmacological activity, which was found to reside mainly in the trans isomer (3-II b). The adrenolytic activity of (3-II b) is comparable with that of the related 2-methyl derivative (1-III), while it is higher than that of (IV) in which the piperazine nucleus is C-unsubstituted.
