[Synthesis and pharmacological activity of N-(dialkylaminoethyl)amides and dialkylaminoethyl esters of alpha-(arylamino)phenylacetic acids].

: A series of N-(dialkylaminoethyl) amides and (dialkylaminoethyl) esters of alpha-(arylamino) phenylacetic acids were synthesized. For several amidic derivatives pharmacological screening showed appreciable analgesic antiinflammatory and sedative activity, whereas some esteric derivatives displayed significant antispasmodic activity.
