yet inhibition of dopamine uptake potency remained comparably high (IC(50) range = 1.5-2.5 nM). Interestingly, the 4'-Cl analogue (+/-)-6 substituted less in rats trained to discriminate cocaine than the 4'-F analogue (+/-)-5. These studies demonstrate that manipulation of the 2-, N-, and 3-position substituents in the 3alpha-(diphenylmethoxy)tropane class of dopamine uptake inhibitors can result in ligands
通常,基于3α-(二苯甲氧基)托烷(苯并卓平)的多巴胺摄取抑制剂在精神兴奋剂滥用模型中未显示出可卡因样的药理活性,因此已被提议作为治疗可卡因成瘾的潜在药物。然而,发现一些(S)-2-碳烷氧基取代的3α-[双(4-氟苯基)甲氧基]托烷类似物可刺激运动能力并替代受过训练的可卡因识别对象,这表明了2-位取代基的作用。调解这些可卡因样的行为。在这里,我们描述了一系列新型的N和2-取代的3α-[双(4-氟-或4-氯苯基)甲氧基]托烷类似物的合成。这些类似物大多数都表现出与多巴胺转运蛋白的高亲和力结合(DAT; K(i)= 1.8-40 nM),和其他单胺转运蛋白和毒蕈碱M(1)受体的选择性。当(S)-2-羰基烷氧基取代基被(S)-2-乙烯基取代时,所得类似物11在该系列(K(i)= 1.81 nM)中显示出最高的DAT结合亲和力,其DAT选择性优于血清素转运蛋白( SERT; 989倍),去甲肾上腺素转运蛋白(NET;
