Abstract:
The introduction of a hydroxyl group into the 5-position of the diaryl furanone system provides highly selective inhibitors of cyclooxygenase-2. These molecules can be converted into their sodium salts which are water soluble, facilitating intravenous formulation. These salts show excellent potency in rat models of pain, fever and inflammation.
