  摘要：

  据报道2-苯基环丙基甲胺（PCPMA）类似物是选择性5-羟色胺2C激动剂。在相同的支架的基础上，我们设计并合成了一系列多巴胺D3R配体的双位衍生物。这些新化合物中的许多对D3R表现出很高的结合亲和力，并且具有出色的选择性。化合物（1R，2R）-22e及其对映异构体（1S，2S）-22e对D3R表现出相当的结合亲和力，但前者是有效的D3R激动剂，而后者则充当拮抗剂。分子对接研究表明，DPM的正构结合口袋中PCPMA部分的结合姿势不同，这可能解释了对映异构体的不同功能。化合物（1R，2R）-30q对D3R具有高结合亲和力（Ki = 2.2 nM），并且具有良好的选择性，以及良好的生物利用度和小鼠的脑部渗透特性。这些结果表明，PCPMA支架可作为胺能GPCR配体设计的优先支架。

  Cinnamic acid and its derivatives are known for anti-tubercular activity. The present study reports the synthesis of cinnamic acid derivatives via bioisosteric replacement of terminal carboxylic acid with "oxadiazole". A series of cinnamic acid derivatives (styryl oxadiazoles) were designed and synthesized in good yields by reaction of substituted cinnamic acids (2, 15a-15s) with amidoximes. The synthesized
