    名称:
    Effect of Structural Modification of Enol−Carboxamide-Type Nonsteroidal Antiinflammatory Drugs on COX-2/COX-1 Selectivity
    摘要:
    Meloxicam (5), an NSAID in the enol-carboxamide class, was developed on the basis of its antiinflammatory activity and relative safety in animal models. In subsequent screening in microsomal assays using human COX-1 and COX-2, we discovered that it possessed a selectivity profile for COX-2 superior to piroxicam and other marketed NSAIDs. We therefore embarked on a study of enol-carboxamide type compounds to determine if COX-2 selectivity and potency could be dramatically improved by structural modification. Substitution at the 6- and 7-positions of the 4-oxo-1,2-benzothiazine-3-carboxamide, alteration of the N-methyl substituent, and amide modification were all examined. In addition we explored several related systems including the isomeric 3-oxo-1,2-benzothiazine-4-carboxamides, thienothiazines, indolothiazines, benzothienothiazines, naphthothiazines, and 1,3- and 1,4-dioxoisoquinolines. While a few examples were found with greater potency in the COX-2 assay, no compound tested had a better COX-2/COX-1 selectivity profile than that of 5.

  • Preparation and reactivity of N-phenyl- and N-methyl-o-diazoacetyl-benzenesulphonamide. A novel synthesis of benzothiazine dioxides

    2-benzothiazin-4-one 1,1-dioxide (X; R = Ph or Me). Toluene-p-sulphonic acid effects a similar cyclisation but the thiazine dioxides are in this case accompanied by benzisothiazole derivatives (XIII; R = Ph or Me). Thermolysis of the diazo-ketones also provides the thiazine dioxides along with their 3-oxo-isomers (XIX) arising by cyclisation of the keten which is the product of Wolff rearrangement. Photolysis
