Cyclooxygenase-2 (COX-2) inhibitors are common anti-inflammatory drugs with pleiotropic, endogenous actions that could be useful in the management of breast cancer. Here, we provide a complete understanding of the biochemistry of COX-2 and discuss the various molecular mechanisms behind its increased expression in breast cancer. We also analyze the possible mechanisms responsible for the antica...

BACKGROUND Evidence on the benefits of combining cyclooxygenase-2 inhibitor (COX-2) in treating non-small cell lung cancer (NSCLC) is still controversial. We investigated the efficacy and safety profile of cyclooxygenase-2 inhibitors in treating NSCLC. METHODS The first meta-analysis of eligible studies was performed to assess the effect of COX-2 inhibitors for patients with NSCLC on the over...

Considerable efforts have been directed towards the discovery of selective cyclooxygenase isoxyme 1 (COX-1) inhibitors due to recent work highlighting involvement COX-1 in pathogenesis pain, neuroinflammation, cancer and cardiovascular disorders. In this context, paper aims describe 2-pyrazolines endowed with inhibitory potency. An efficient microwave-assisted synthetic method was applied for p...

We examined the regulation of matrix metalloproteinase (MMP) production by mitogen-activated protein kinases and cyclooxygenases (COXs) in fibroblast-like synoviocytes (FLSCs). IL-1beta and TNF-alpha stimulated FLSC extracellular signal-regulated kinase (ERK) activation as well as MMP-1 and -13 release. Pharmacologic inhibitors of ERK inhibited MMP-1, but not MMP-13 expression. Whereas millimol...

The issue of the risk-benefit assessment of cyclooxygenase-2 (COX-2) inhibitors, as compared to traditional non-steroidal anti-inflammatory drugs (tNSAIDs), is far from being resolved. These compounds need to be carefully re-evaluated in order to avoid hasty conclusions, as it happened when COX-2 inhibitors were introduced into clinical practice. Several arguments support the concept, that COX-...
