ABSTRACT:
FIELD OF THE INVENTION
The present invention describes novel nitrosated and/or nitrosylated cyclooxygenase 2 (COX-2) inhibitors and novel compositions comprising at least one nitrosated and/or nitrosylated cyclooxygenase 2 (COX-2) inhibitor, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or at least one therapeutic agent. The present invention also provides novel compositions comprising at least one COX-2 inhibitor. The present invention also provides methods for treating inflammation, pain and fever; for treating and/or improving the gastrointestinal properties of COX-2 inhibitors; for facilitating wound healing; for treating and/or preventing renal toxicity; and for treating and/or preventing other disorders resulting from elevated levels of cyclooxygenase-2.
BACKGROUND OF THE INVENTION
Nonsteroidal anti-inflammatory compounds (NSAIDs) are widely used for the treatment of pain, inflammation, and acute and chronic inflammatory disorders such as osteoarthritis and rheumatoid arthritis. These compounds inhibit the activity of the enzyme cyclooxygenase (COX), also known as prostaglandin G/H synthase, which is the enzyme that converts arachidonic acid into prostanoids. The NSAIDs also inhibit the production of other prostaglandins, especially prostaglandin G

, prostaglandin H
2
and prostaglandin E
2
, thereby reducing the prostaglandin-induced pain and swelling associated with the inflammation process. The chronic use of NSAIDs has been associated with adverse effects, such as gastrointestinal ulceration and renal toxicity. The undesirable side effects are also due to the inhibition of prostaglandin in the affected organ.
Recently two isoforms of cyclooxygenase, encoded by two distinct genes (Kujubu et al,
J. Biol. Chem.,
266, 12866-12872 (1991)), have been identified—a constitutive form, cyclooxygenase-1 (COX-1), and an inductive form, cyclooxygenase-2 (COX-2). It is thought that the antiinflammatory effects of NSAIDs are mediated by the inhibition of COX-2, whereas the side effects seem to be caused by the inhibition of COX-1. The NSAIDs currently on the market either inhibit both isoforms of COX with little selectivity for either isoform or are COX-1 selective. Recently compounds that are selective COX-2 inhibitors have been developed and marketed. These selective COX-2 inhibitors have the desired therapeutic profile of an antiinflammatory drug without the adverse effects commonly associated with the inhibition of COX-1. However, these compounds can result in dyspepsia and can cause gastropathy (Mohammed et al,
N. Engl. J. Med.,
340(25) 2005 (1999)).
