[Bromoacyl analogues of phosphatidylcholine with intramolecular fluorescence quenching and their use as substrates for continuous monitoring of phospholipase A2 activity].

Two new derivatives of phosphatidylcholine with intramolecular fluorescence quenching were obtained by substituting residues of pyrene butyric and bromine-containing fatty acids for acyl chains. The two compounds can be used for quantitative evaluation of catalytic activity of pancreatic phospholipase A2 in kinetic mode.
