1-PALMITYLTHIO-2-PALMITOYLAMIDO-1,2-DIDEOXY-SN-GLYCERO-3-PHOSPHOCHOLINE Usage And Synthesis

Description

Thioetheramide-PC is a structurally modified phospholipid that functions as a competitive, reversible inhibitor of secretory phospholipase A₂ (sPLA₂). The IC₅₀ value for thioetheramide-PC is 2 μM at a substrate concentration of 0.5 mM. In addition to binding to the catalytic site of sPLA₂, thioetheramide-PC also binds to the activator site of this enzyme. The binding of thioetheramide-PC to the activator site is tighter than its binding to the catalytic site. The result of this dual interaction is that at low concentrations thioetheramide-PC may activate phospholipase activity rather than inhibiting it.

Uses

Thioetheramide-PC (1-Palmitylthio-2-palmitoylamido-1,2-dideoxy-sn-glycero-3-phosphorylcholine) is a structurally modified phospholipid that acts as a competitive, reversible inhibitor of secretory phospholipase A2 (sPLA2). Thioetheramide-PC has an IC50 value of 2 μM at a substrate concentration of 0.5 mM. In addition to binding to the catalytic site of sPLA2, Thioetheramide-PC also binds to the activation site of the enzyme. Thioetheramide-PC binds more tightly to the activation site than to the catalytic site. As a result of this dual interaction, at low concentrations, Thioetheramide-PC may activate phospholipase activity rather than inhibit it.
