AACOCF3 is a potent and selective inhibitor of cytosolic phospholipase A2 with IC50 value of 15 μM [1].

Phospholipase A2 is an enzyme that releases fatty acids from glycerol. Cytosolic phospholipase A2 (cPLA2) plays an important role in inflammation by inducing the release of arachidonic acid from membrane phospholipids.

AACOCF3 is a potent and selective inhibitor of the 85-kDa cPLA2. AACOCF3 inhibited macrophage PLA2 with IC50 value of 15 μM in a concentration-dependent way [1]. AACOCF3 inhibited the release of arachidonic acid (AA) with IC50 values of 2 and 8 μM in platelets and calcium ionophore-challenged U 937 cells, respectively. Also, AACOCF3 inhibited the production of thromboxane B and 12-hydroxyeicosatetraenoic acid (12-HETE), the major metabolites of AA in a dose-dependent way. These results suggested that cPLA2 played a critical role in the generation of AA and 12-HETE [2].

In mice, AACOCF3 inhibited chronic inflammatory responses and inhibited phorbol 12-myristate

13-acetate (PMA)-induced chronic ear edema. In ovalbumin-challenged BALB/c mice, AACOCF3 (20mg/kg) inhibited airway hyper-responsiveness and reduced cellular recruitment in the airway inflammation and airway lumen [3].
