title: Preparation and local anaesthetic activity of N-[2-(tert-amino)ethyl]- and N-(lupinyl)-benzotriazol-1/2-ylacetamides.
abstract: Two sets of N-[2-(tert-amino)ethyl]- and N-[(quinolizidin-1 alpha-yl) methyl]-benzotriazol-2-ylacetamides, bearing substituents on position 5 or 5 and 6, were prepared and tested for local anaesthetic activity in comparison with lidocaine. Most of the prepared compounds exhibited a fairly good activity comparable or superior to that of lidocaine. The introduction of substituents on the benzene ring and the replacement of the usual tert-amino alkyl chains with the quinolizidin-1 alpha-ylmethyl (lupinyl) moiety were quite profitable for both the intensity and duration of activity. One selected compound was subjected to a large pharmacological screening and found endowed with a good level of the purported antiarrhythmic activity without any other disturbing activity.
