| Description | AACOCF3 (Arachidonyl trifluoromethyl ketone) is a cell-permeable trifluoromethyl ketone analog of arachidonic acid. It is a potent and selective slow binding inhibitor of the 85-kDa cytosolic phospholipase A2 (cPLA2). By blocking the production of arachidonate and 12-hydroxyeicosatetraenoic acid in calcium ionophore-challenged platelets, AACOCF3 hinders their synthesis. Moreover, AACOCF3 inhibits glucose-induced insulin secretion from isolated rat islets. Given its diverse applications, AACOCF3 holds promise for cardiovascular disease research. |
| In vitro | AACOCF3 inhibits the release of arachidonic acid from calcium ionophore-challenged U937 cells with IC50 of 8 μM and from platelets with IC50 of 2 μM[1]. AACOCF3 (10 μM) suppresses phosphate-induced calcification and osteogenic/chondrogenic signaling in HAoSMCs. AACOCF3 significantly inhibits both basal and Pi-induced release of arachidonic acid, the product of PLA2 activity[2]. |
| In vivo | AACOCF3 (10 mg/kg; gavage; 5 days a week; ApoE–/– mice (6-week-old males) were fed a high-cholesterol diet) significantly reduces type III collagen plaque expression, but had no significant influence on total collagen accumulation[3]. |
