CL 118326
CL 118326 is a potent, selective, competitive inhibitor of mammalian pancreatic phospholipase A2 (PLA2) and a weak antagonist of platelet-activating factor receptor (PAF receptor). CL 118326 competitively inhibits mammalian pancreatic PLA2 (porcine: IC50 = 1.55 μg/mL), and shows no activity against snake venom or bee venom PLA2. CL 118326 inhibits PAF-induced and thrombin-induced platelet aggregation, as well as the release of leukotriene (LTC4) and histamine from basophil-enriched leukocytes. CL 118326 can be used for research on inflammation and allergic reactions.

Biological Activity
CL 118326 (5 min) inhibits thrombin-induced (IC50 = 7.9 μM) and PAF-induced (IC50 = 5.8 μM) rabbit platelet aggregation, but does not inhibit aggregation induced by arachidonic acid or ADP, and exhibits no PAF agonist activity[1].
CL 118326 (70 min) inhibits histamine and LTC4 release from human basophil-enriched leukocytes stimulated by antigens and ionophores, with IC50 values ranging from 1.36 to 2.34 μg/mL[1].

Result:Reduced porcine pancreatic PLA2-induced skin lesion size by 60.4% (from 83.0 mm2 to 32.8 mm2) and 51.0% (from 36.4 mm2 to 17.0 mm2) in one experiment, and by 84.4% (from 124.0 mm2 to 19.3 mm2) and 87.2% (from 56.2 mm2 to 7.2 mm2) in a second experiment, for 50-unit and 25-unit PLA2 challenges respectively.
Reduced lesion size relative to controls across multiple PLA2 dose levels at 20 μg.
