PIA is a synthetic analog of palmitoyl ethanolamide which incorporates isopropyl amide in place of the native ethanolamide. PIA does not bind appreciably to either CB1 or CB2 receptors. PIA inhibits both the transport (re-uptake) of tritiated AEA into intact cells, as well as the subsequent hydrolysis of AEA to arachidonate and ethanolamine, with 50% inhibition of FAAH-mediated hydrolysis at 10 μM.
