title: Synthesis of phospholipids on a glyceric acid scaffold: design and preparation of phospholipase A2specific substrates.
abstract: Synthesis of a new series of phospholipid analogues to serve as activity-based probes of secretory phospholipase A2enzymes is reported. The synthesis is based upon 1) preparation of long-chain esters and amides of glyceric acid, followed by 2) regioselective derivatization of the diol function of the molecule to achieve phosphorylation at the primary hydroxyl group, and to introduce the incipientsn-2-ester group of the target compounds. The sequence has been shown to allow incorporation of fluorescent, paramagnetic, and redox-active reporter groups, leading to phospholipid analogues applicable to detect and measure enzyme activity, to develop highly specific, real-time spectroscopic assay of phospholipase A2enzymes, as well as to track the metabolic fate of the hydrolysis products. The synthetic method has a great deal of flexibility to open the way to the design and synthesis of activity-probes for other phospholipid metabolizing enzymes as well.
