1 A high affinity (1-2 nM) radioiodinated, photoaffinity probe for the dopamine transporter, 1-(2-[bis-(4-fluorophenyl)-methoxylethyl)-4-(2-[4-azido-3- [125I]iodophenyl]ethyl)piperazine ([125I]FAPP) has been synthesized. 1-(2-[bis-(4-fluorophenyl)-methoxylethyl)-4-(2-[4-azido-3- [125i]iodophenyl]ethyl)piperazine carboxyl ester lipase Homo sapiens
2 Upon photolysis, [125I]FAPP incorporates into a striatal polypeptide of apparent Mr 62,000 as visualized by autoradiography following sodium dodecyl sulfate-PAGE. Sodium Dodecyl Sulfate carboxyl ester lipase Homo sapiens
3 Photoincorporation of [125I]FAPP into the Mr 62,000 polypeptide was stereoselectively inhibited by various dopamine uptake agents with a potency order typical of the dopamine transporter. Dopamine carboxyl ester lipase Homo sapiens
4 [125I]FAPP should prove to be a useful probe for the molecular characterization of the dopamine uptake site in various tissues and under certain pathophysiological states. Dopamine carboxyl ester lipase Homo sapiens
