Phospholipase A2 (PLA2) catalyzes the hydrolysis of phospholipids at the sn-2 position leading to the production of lysophospholipids and free fatty acids. Calcium-dependent cytosolic PLA2 (cPLA2α) is a 85 kDa enzyme that plays a key role in the arachidonic cascade and the inflammatory response associated with this metabolic pathway. CAY10502 is a potent inhibitor of calcium-dependent cytosolic PLA2α (cPLA2α) with an IC50 value of 4.3 nM for the purified enzyme from human platelets. It inhibits arachidonic acid mobilization from A23187-stimulated or TPA-stimulated human platelets with IC50 values of 570 and 0.9 nM, respectively.
