Abstract
Abstract 3,4,5-Trimethoxybenzamides of pyridylalkylamines such as pyridylmethylamine and of phenylalkylamines such as phenylmethylamine, phenethylamine and Beta hydroxyphenethylamine, as well as derivatives thereof wherein the aromatic nucleus in the amine is substituted by one or more hydroxy, carboxy, halo, aryl, alkyl, nitro, alkoxy, aryloxy or thioalkoxy groups. The compounds are relatively non-toxic and are useful for pharmacological purposes. They exert a specific effect on the central nervous system and a somewhat lesser effect on muscle function. They are useful as relatively mild tranquilizers in the control of anxiety states, excessive aggressiveness and hyperactivity.
