  • Publication number: 20030212123
    Abstract: Treating or preventing inflammatory processes and diseases in dogs associated with the activity of inducible cyclo-oxygenase-2 (COX-2), while at the same time reducing or eliminating undesirable side effects associated with simultaneous inhibition of the activity of constitutive cyclo-oxygenase-1 (COX-1) by selectively inhibiting COX-2 activity with reference to COX-1 activity, wherein the selectivity ratio or COX-2:COX-1 activity inhibition is at least 3:1 based on ex vivo inhibition levels measured in whole blood; the inhibitor is a member selected from the group of anti-inflammatory compounds consisting essentially of salicylic acid derivatives, p-aminophenol derivatives, indole and indene acetic acids, heteroaryl acetic acids, arylpropionic acids, anthranilic acids, enolic acids, and alkanones; the inhibitor in particular is comprised of (+)(S)-enantiomer of 6-chloro-&agr;-methyl-9H-carbazole-2-acetic acid.

  • Patent number: 6506785
    Abstract: Treating or preventing the early stages of degeneration of articular cartilage or subchondral bone in the affected joint of a mammal is accomplished by administering a chondroprotective compound of Formula (I): where A is hydroxy, (C1-C4)alkoxy, amino, hydroxy-amino, mono-(C1-C2)alkylamino, di-(C1-C2)alkylamino; X and Y are independently H or (C1-C2)alkyl; and n is 1 or 2; R6 is halogen, (C1-C3)alkyl, trifluoromethyl, or nitro; R9 is H; (C1-C2)alkyl; phenyl or phenyl-(C1-C2)alkyl, where phenyl is optionally mono-substituted by fluoro or chloro; —C(═O)—R, where R is (C1-C2)alkyl or phenyl, optionally mono-substituted by fluoro or chloro; or —C(═O)—O—R′, where R1 is (C1-C2)alkyl. This treatment ameliorates, diminishes, actively treats, reverses or prevents any injury, damage or loss of articular cartilage or subchondral bone subsequent to said early stage of said degeneration.
