Synthesis, anti-inflammatory and antinociceptive activity of some novel benzothiazole derivatives

A new series of derivatives bearing benzothiazol-2-one or benzothiazole ring system conjugated to other different heterocycles were prepared using 5,6-dimethoxy-3-benzothiazol-2(3H)-one (1) as a starting material. The structures of the newly synthesized products have been established based on analytical and spectral data. In addition, the anti-inflammatory and antinociceptive activities of some of the products were evaluated. Our data showed that many derivatives have promising activities as anti-inflammatory and antinocicepative agents.
