690 nM) transporters. Therefore, the most potent dopamine uptake inhibitors in this series were highly selective for the dopamine transporter. Preliminary behavioral studies of several of these analogs (7a-e) suggested that the compounds did not display a cocaine-like behavioral profile, despite their ability to inhibit dopamine uptake. The present data coupled with the observed differences from cocaine
制备了一系列4'-取代和4',4“-二取代的3α-(二苯基甲氧基)托烷类似物作为多巴胺转运蛋白的新型探针。这些化合物在多巴胺,去甲肾上腺素和5-羟色胺转运蛋白的放射性标记结合试验中进行了评估。 。所有这些化合物在大鼠尾状壳状核中单相置换[3H] WIN 35,428的Ki值范围为11.8至2000 nM。该系列中最有效的化合物是4',4“-二氟3α-(二苯基甲氧基)托烷7c Ki = 11.8 nM。所有这些化合物均抑制大鼠尾状壳核蛋白中的多巴胺摄取(IC50 = 24-4456 nM),这与多巴胺转运蛋白的结合亲和力显着相关(r = 0.907; p> 0.0001)。没有一种化合物在去甲肾上腺素上显示出高亲和力结合(Ki> 4800 nM)或血清素(Ki> 690 nM)转运蛋白。因此,该系列中最有效的多巴胺摄取抑制剂对多巴胺转运蛋白具有高度选择性。对其中一些类似物(7a-e)的初步行
