CAY10502

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 (cPLA2?) is a 85 kDa enzyme that plays a key role in the arachidonic cascade and the inflammatory response associated with this metabolic pathway.{14663} CAY10502 is a potent inhibitor of calcium-dependent cytosolic PLA2? (cPLA2?) with an IC50 value of 4.3 nM for the purified enzyme from human platelets.{14126} It inhibits arachidonic acid mobilization from A23187-stimulated or TPA-stimulated human platelets with IC50 values of 570 and 0.9 nM, respectively.{14126}
