Our structure–activity relationship studies with N6-(2-(4-(1H-indol-5-yl)piperazin-1-yl)ethyl)-N6-propyl-4,5,6,7-tetrahydrobenzo[d]thiazole-2,6-diamine derivatives led to development of a lead compound (−)-21a which exhibited very high affinity (Ki, D2 = 16.4 nM, D3 = 1.15 nM) and full agonist activity (EC50 (GTPγS); D2 = 3.23 and D3 = 1.41 nM) at both D2 and D3 receptors. A partial agonist molecule
我们对N 6 -(2-(4-(1 H -吲哚-5-基)哌嗪-1-基)乙基)- N 6 -丙基-4,5,6,7-四氢苯并的结构-活性关系研究[ d ]噻唑-2,6-二胺衍生物导致了先导化合物 (−)- 21a的开发,该化合物表现出非常高的亲和力(K i,D 2 = 16.4 nM,D 3 = 1.15 nM)和完全激动剂活性(EC 50 (GTPγS);D 2 = 3.23 和 D 3 = 1.41 nM) 在 D 2和 D 3受体上。还鉴定了部分激动剂分子(−)- 34 (EC 50 (GTPγS);D 2 = 21.6 ( E max = 27%) 和D 3 = 10.9 nM)。在帕金森病 (PD) 动物模型中,(−)- 21a在逆转利血平大鼠运动功能减退方面非常有效,且作用持续时间较长,表明其作为抗 PD 药物的潜力。化合物(-)- 34还能够显着提高上述PD动物模型的运动活性,这意
