  Synthesis of new thienopyrimidobenzothiazoles and thienopyrimidobenzoxazoles with analgesic and antiinflammatory properties

  摘要：

  As an extension of research on analgesic and antiinflammatory compounds, a series of substituted analogues based on the novel 4H-thieno[2',3':4,5]pyrimido[2,1-b]benzothiazole and 4H-thieno[2',3':4,5]pyrimido[2,1-b]benzoxazole ring systems was synthesized. The compounds were obtained by reaction of 2 amino-3-carbethoxy-4,5-disubstituted thiophenes with 2-chlorobenzothiazole and 2-chlorobenzoxazole, respectively. Starting from 2-carbomethoxy-3-aminothiophene, 11H-thieno[3',2':4,5]pyrimido[2,1-b]benzothiazol-11-one and 11H-thieno[3',2':4,5]pyrimido[2,1-b]benzoxazol-11-one were prepared in the same way. Synthesized compounds were evaluated for their potential analgesic activity in phenylquinone-induced writhing test in mice and fdr their potential antiinflammatory activity in carrageenan-induced rat-paw oedema test, in acetic-acid peritonitis assay and in croton oil-induced mouse-ear oedema test. 9,10,11,12-Tetrahydro-12H-benzothieno[2',3':4,5]pyrimido[2,1-b]benzoxazol-12-one 12 was the most active derivative in the series in all performed tests. It showed remarkable analgesic and antiinflammatory activities associated with an excellent gastric tolerance.
