Amides and formamidines with antinociceptive activity: note I

Pursuing our investigations on N-aryl or N-cycloalkyl substituted amides and formamidines with antiinflammatory and/or analgesic activity, two set of cycloalkyl substituted amides and formamidines were prepared and tested for analgesic activity against a chemical stimulus. Some compounds, particularly the amides 7, 11, 17 and the formamidine 35 proved to be endowed with this activity.
