  • Patent number: 6498166
    Abstract: The invention provides the compounds of formula (I) wherein: R0 and R1 are independently selected from H, halogen, C1-6alkyl, C1-6alkoxy, or C1-6alkoxy substituted by one or more fluorine atoms; R2 is halogen, CN, CONR4R5, CO2H, CO2C1-6alkyl, or NHSO2R4; R3 is C1-6alkyl or NH2; and R4 and R5 are independently selected from H, C1-6alkyl, phenyl, phenyl substituted by one or more atoms or groups (selected from halogen, C1-6alkyl, C1-6alkoxy, or C1-6alkoxy substituted by one or more fluorine atoms), or together with the nitrogen atom to which they are attached form a saturated 4 to 8 membered ring; and pharmaceutically acceptable derivatives thereof. Compounds of formula (I) are potent and selective inhibitors of COX-2 and are of use in the treatment of the pain, fever, inflammation of a variety of conditions and diseases.

  • Patent number: 6177419
    Abstract: Compounds and methods of preparing compounds represented by structural formula (I): wherein X represents any suitable counter-anion; R1 and R2 independently represent hydrogen, C1-6 alkoxy or nitro; R3, R4, R5 and R6 each independently represents hydrogen, hydroxy, halo, C1-6 alkyl, C2-6 alkenyl or C1-6 alkoxy; and R7, R8, R9 and R10 each independently represents hydrogen, hydroxy, halo, C1-6 alkyl, C2-6 alkenyl or C1-6 alkoxy. Compounds represented by structural formula (I) are useful in treating or preventing free radical-associated diseases or conditions in mammals.
