title: Synthesis and SAR study of imidazo[2,1-b]benzothiazole acids and some related compounds with anti-inflammatory and analgesic activities.
abstract: Some (un)substituted imidazo[2,1-b]benzothiazole carboxylic or acetic acids and some related compounds, i.e. imidazo[2,1-b]naphthol[2,1-d]thiazole, 4H-imidazo[2,1-c][1,4]benzothiazine, 4,5-dihydroimidazo[2,1-d][1,5]benzothiazepine carboxylic and acetic acids were synthesized and tested in vivo in order to study the structure-activity relationships (SAR) of their antiinflammatory and analgesic activities. Pharmacological assays confirmed the interest of this class of compounds as potential antiinflammatory and analgesic drugs with low side effects.
