Biochem/physiol Actions

Rofecoxib is a selective cyclooxygenase-2 (COX-2) inhibitor with >800-fold COX-2 selectivity in CHO cells expressing human COX-1 and COX-2.
Rofecoxib is derived from furanone and has the ability to cross human placenta. Along with anti-inflammatory action, it possesses analgesic and antipyretic properties. Cytosolic hepatic enzymes are responsible for the metabolism of rofecoxib. It is known to cause oligohydramnios and ductus arteriosus constrictions. Rofecoxib inhibits the action of CYP1A2 (cytochrome P450 family 1 subfamily A member 2). It might be associated with aseptic meningitis. Rofecoxib is known to ameliorate the risk of colorectal adenoma, but might contribute to toxicity.

The randomized prospective double-blinded clinical trial (RCT) is accepted as Level I evidence and is highly regarded. However, RCTs that gained FDA approval of drugs such as Vioxx, Fen-Phen, and oral and intravenous bisphosphonates have proven to generate misleading results

While it is now clear that paracetamol is ineffective for spinal pain, there is not consensus on the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) for this condition. We performed a systematic review with meta-analysis to determine the efficacy and safety

There is concern that cyclooxygenase (COX)-2 inhibitors may promote atherothrombosis by inhibiting vascular formation of prostacyclin (PGI2) and an increased thrombotic risk of COX-2 inhibitors has been reported. It is widely accepted that the prothrombotic effects of COX-2 inhibitors can

2,5-Dimethyl-celecoxib (DMC) is a close structural analog of the selective cyclooxygenase-2 (COX-2) inhibitor celecoxib (Celebrex) that lacks COX-2-inhibitory function. However, despite its inability to block COX-2 activity, DMC is able to potently mimic the anti-tumor effects of celecoxib in vitro

A drug design for safer phenylbutazone was been explored by reactivity and docking studies involving single electron transfer mechanism, as well as toxicological predictions. Several approaches about its structural properties were performed through quantum chemistry calculations at the B3LYP level
