The synthesis of new halogenated series of 4-anilinoquinoline-3-carboxylic acids, N-[3-carboxyquinolyl(4)]anthranilic acids and their corresponding esters is reported. These have been obtained by reacting 4-chloro-3-carbethoxy-quinolines with variously substituted anilines and methyl anthranilate respectively. The synthesized compounds were tested for antiinflammatory and analgesic activities; some of them showed a good analgesic activity, sometimes higher than that of indomethacin, used as reference drug.
