Oleyloxyethyl phosphorylcholine is an inhibitor of PLA₂ with an IC₅₀ value of 6.2 μM for porcine pancreatic PLA₂.

to examine the phospholipids including oleyloxyethyl phosphorylcholine as pla2 inhibitors, the enzyme assay was employed. determinations were performed below critical micelle concentration. porcine pancreatic pla2 and phospholipid inhibitor were preincubated for 2 min at 37°c in buffer at ph 8.5. introduction of [l4c]arachidonate phosphatidylcholine initiated the enzymatic reaction, which is quenched after 5 min at 37°c. in this manner 50% inhibitor concentrations were determined for mepacrine and alkylphosphorylcholines, indicating oleyloxyethyl phosphorylcholine was an inhibitor of pla2 with an ic50 of 6.2 μm for porcine pancreatic pla2 [1].
