General description

A nonsteroidal anti-inflammatory drug (NSAID) that acts as a reversible and competitive inhibitor of cyclooxygenase 1 (COX-1) (IC50 = 4.85 µM). Inhibits COX-2 at higher concentrations (IC50 = 223 µM). Blocks aspirin inactivation of COX-1 (EC50 antagonism of 200 µM aspirin = 290 nM). Shown to reduce the total Aβ secretion (Amyloid β40 and 42) in human neuronal cells and offers neuroprotection against glutamate-, nitric oxide-, and superoxide-induced damage. Reported to activate peroxisome proliferator-activated receptors (PPAR) α and γ in both CV-1 and C3H10T1/2 cells (~100 µM-500 µM).
A nonsteroidal anti-inflammatory drug (NSAID) that acts as a reversible, competitive, non-selective cyclooxygenase (COX) inhibitor (IC50 = 4.85 µM for purified COX-1 and 223 µM for purified COX-2). Also reported to inhibit COX-1 and COX-2 activity in intact bovine aortic endothelial cells (BAEC) (IC50 = 7 µM for COX-1 and 72.7 µM for COX-2). Potently blocks aspirin inactivation of COX-1 (EC50 antagonism of 200 µM aspirin ~290 nM for ovine COX-1). Decreases the secretion of total Aβ (Amyloid β40&42) by human neuronal cells and offers neuroprotection against glutamate-, nitric oxide- and superoxide-induced damage. Activates peroxisome proliferator activated receptors α and γ in both CV-1 and C3H10T1/2 cells (~100 µM - 500 µM).

Both nonsteroidal anti-inflammatory drugs, such as ibuprofen, and the prototypical selective cyclooxygenase (Cox)-2 inhibitors DuP-697 and NS-398 block the inhibition of Cox-1 by aspirin in vitro. However, clinical studies have shown that the Cox-2 selective drugs (or coxibs) rofecoxib and

Non-steroidal anti-inflammatory drugs (NSAIDs) reduce the risk of Alzheimer's disease, although the underlying mechanisms are unknown. Glutamate excitotoxicity has been implicated in Alzheimer's disease, Parkinson's disease, and others. We examined the effects of aspirin, acetaminophen, and ibuprofen on cultured primary

Since the discovery of a cytokine-inducible isozyme of cyclooxygenase (COX-2), its pharmacologic inhibition has been the subject of recent investigations. These include tests for the selectivity of known nonsteroidal antiinflammatory drugs (NSAIDs) on the constitutive enzyme of cyclooxygenase (COX-1) compared

Recent studies show that a mononuclear phagocyte lineage, including microglia, plays a possible role in the pathogenesis of Alzheimer's disease through nitric oxide (NO)-mediated neurotoxicity. Epidemiological studies show that nonsteroidal anti-inflammatory drugs (NSAIDs) have a protective effect against Alzheimer's disease.
