The pharmacological properties of the iodinated derivative of cocaine (E)-N-(3-iodoprop-2-enyl)-2beta-carbomethoxy-3beta-(4'-me thylphenyl)nortropane (PE2I) were evaluated in vitro in the rat. Binding experiments on rat striatal membranes showed that PE2I selectively recognized the dopamine transporter (DAT) according to a single binding site model with high affinity (K(d) = 4 nM, B(max) = 12 pmol/mg protein). In the cortical membranes, the binding of PE2I was also selectively associated with the DAT (IC(50) for GBR 12909 = 6 nM versus more than 1000 nM for paroxetine), with similar affinity to that of the striatum. Autoradiographic experiments on rat brain sections with [(125)I]PE2I were in agreement with the localization of the DAT. In addition, PE2I was shown to be a potent inhibitor of dopamine uptake, with IC(50) values similar to those for GBR 12909 and 2beta-carbomethoxy-3beta-(4'-iodophenyl)-tropane (beta-CIT) (2-6 nM). All of these findings, combined with previously published data, support the use of PE2I as a selective and potent tool to study the DAT both in vivo and in vitro.
