The COX-2 enzyme was discovered in 1988 by Daniel Simmons, a Brigham Young University researcher. [30] The mouse COX-2 gene was cloned by UCLA scientist Harvey Herschman, a finding published in 1991. [31] The basic research leading to the discovery of COX-2 inhibitors has been the subject of at least two lawsuits.
Once the COX-2 enzyme was identified, Dup-697 became the building-block for synthesis of COX-2 inhibitors. Celecoxib and rofecoxib, the first COX-2 inhibitors to reach market, were based on DuP-697. [ 5 ] [ 6 ] It took less than eight years to develop and market the first COX-2 inhibitor, with Celebrex ( celecoxib ) launched in December 1998 ...
The first CINODs were developed in the 1990s, and as yet none have been approved for use by the general public. The importance of developing such drugs was increased when COX-2-specific NSAIDs rofecoxib (Vioxx) and lumiracoxib (Prexige) were removed from major pharmaceutical markets in the mid-2000s due to vascular safety concerns.
Newer NSAID drugs called COX-2 selective inhibitors have been developed that inhibit only COX-2, with the hope for reduction of gastrointestinal side-effects. [8] However, several COX-2 selective inhibitors have subsequently been withdrawn after evidence emerged that COX-2 inhibitors increase the risk of heart attack. [9]
Rofecoxib is a selective COX-2 inhibitor, or "coxib". Though the class of coxibs includes several agents, degrees of COX-2 selectivity vary among them, with celecoxib (Celebrex) being the least COX-2 selective, and rofecoxib (Vioxx), valdecoxib (Bextra), and etoricoxib (Arcoxia), being highly COX-2 selective.
