  Synthesis, Dopamine Transporter Affinity, Dopamine Uptake Inhibition, and Locomotor Stimulant Activity of 2-Substituted 3β-Phenyltropane Derivatives

  摘要：

  A series of 2 beta-substituted 3 beta-phenyltropanes were synthesized as analogs of cocaine and tested in vitro for their ability to displace bound [H-3]WIN 35,428 (2b) and inhibit; dopamine uptake in rat caudate-putamen tissue. The analogs bound with high affinity (K-i = 11-22 nM) to the dopamine transporter. Increased lipophilicity at the beta-C(2)-position was found to lead to increased binding affinity and increased dopamine uptake potency. However, a direct correlation between clogP values and binding affinity and potency of uptake inhibition was not observed. The unsaturated ester 7 was found to possess weak dopamine uptake inhibition relative to the high binding affinity (IC50/K-i = 10.2). In vivo measurement of stimulated locomotor activity and drug discrimination against cocaine (10 mg/kg, ip) with selected analogs (4, 6, and 7) demonstrated that the behavioral effects of these drugs were approximately equipotent with those of cocaine, The structure-activity relationships of this series of cocaine analogs supports a pharmacophore model in which lipophilic interactions between the B-C(2)position of 3 beta-phenyltropanes and the cocaine binding site on the dopamine transporter lead to enhanced potency while electrostatic interactions have a nonspecific effect.
