title: Synthesis and pharmacological activity of 5-substituted 2-(N,N-dialkylaminoethyl)amino- and 2-N-methylpiperazinyl-1,3,4-thiadiazoles.
abstract: 5-Substituted 2-amino-1,3,4-thiadiazoles were transformed to their corresponding 2-bromo derivatives. The reaction of the 5-substituted 2-bromo-1,3,4-thiadiazoles with N,N-dialkylaminoethylamines or N-methylpiperazine afforded the corresponding amino-1,3,4-thiadiazole derivatives. All prepared compounds displayed antihistaminic, anticholinergic, and norepinephrine-potentiating activities.
