(±)-Ibuprofen

Cell permeable: no

Primary Target
COX-1

Product competes with ATP.

Reversible: yes

Target IC₅₀: 4.85 µM against COX-1

Toxicity: Harmful (C)

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 β_40&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).
