Several analogs of the potent and selective dopaminetransporter (DAT) ligand 4-[2-(diphenylmethoxy)ethyl]-1-benzylpiperidine, 1a, were prepared and biologicallyevaluated at the dopamine and serotonintransporter (SERT) sites. Several substituents were introduced in the aromatic rings to evaluate the influences of electronic and steric interactions in their binding to the DAT. All the novelanalogs showed
制备了有效的和选择性的多巴胺转运蛋白(DAT)配体4- [2-(二苯甲氧基)乙基] -1-苄基哌啶1a的几种类似物,并在多巴胺和5-羟色胺转运蛋白(SERT)部位进行了生物学评估。在芳香环中引入了几个取代基,以评估电子和空间相互作用对DAT结合的影响。与SERT相比,所有新的类似物在DAT均表现出优先相互作用。分子的N-苄基部分的苯环中的不同芳族取代在选择性中起关键作用。通常,具有强吸电子取代基的化合物在DAT处最具活性和选择性。因此,化合物5a(R = F)和11b(R = NO2)是最有效的化合物(IC50 = 17.2和16.4 nM,选择性最高)(分别为SERT / DAT = 112和108),并且选择性远远高于GBR 12909(SERT / DAT = 6)。用噻吩环对二苯基甲氧基部分的一个苯环进行生物等位置换是可以很好地耐受的,并产生了该系列中最有效的化合物13b(IC50
