Substituted 1-[2-(diphenylmethoxy)ethyl]piperazines were synthesized and tested for inhibitory activity on dopamine uptake by synaptosomal preparations of rat corpus striatum. Especially 4-(3-phenyl-2-propenyl)substitution yielded very potent inhibitors with IC50 values of about 1 to 2 nM, activities that surpass that of benztropine 100 times. Compared with other monoamine uptake processes, the effect on dopamine uptake was highly specific. QSAR-analysis showed that substituents in the diphenylmethoxy group combining a strong inductive effect with a small volume provided optimal potency. In contrast, for those in the solitary phenyl group a combination of strong electron-withdrawing effect and a small volume was required.
