Thioetheramide-PC is a structurally modified phospholipid that functions as a competitive, reversible inhibitor of secretory phospholipase A2 (sPLA2).{808,2624} The IC50 value for thioetheramide-PC is 2 uM at a substrate concentration of 0.5 mM.{808} 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.{808}
