Formamidines with antinociceptive and antiinflammatory activities

Pursuing our investigations on 7-amino-2,3-polymethyleneindole derivatives, a set of 7-(dimethylaminomethylene)-amino-2,3-polymethyleneindoles, together with some other aryl or cycloalkyl substituted formamidines, were prepared and tested for analgesic and antiinflammatory activities. Several compounds resulted endowed with one or both of these activities; the indole derivatives 1 and 2 exhibited a good degree of both of them.
