对多巴胺 D 2受体 (D 2 R) 的部分激动剂活性是第三代抗精神病药——阿立哌唑、brexpiprazole 和卡利拉嗪的主要药理学特征。然而,所有这些药物都有一个共同的苯基哌嗪部分作为主要药效团。在这项研究中,我们设计并合成了一系列基于 2-苯基环丙基甲胺 (PCPMA) 支架的新型化合物,并研究了它们在 D 2 R 的药理活性。一些有效的 D 2通过结合亲和力筛选和 G 蛋白和 β-抑制蛋白测定中的功能活性分析鉴定 R 部分激动剂。结构-功能活性关系结果表明,间隔基团对于微调这些化合物的内在活性至关重要。化合物(+)- 14j和(+)- 14l显示出良好的药代动力学特性和对5-羟色胺2A (5-HT 2A ) 受体的出乎意料的选择性。小鼠超运动模型中的初步抑制作用证明这些 PCPMA 衍生的 D 2 R 部分激动剂作为潜在的新型抗精神病药是有效的。
2‐Aryl‐substituted cyclopropyl aldehydes undergo an unprecedented Au nanoparticle‐catalyzed silaboration leading to rearranged linear b‐ boronate‐bearing silyl enol ethers. Formation of these products is attributed to the ring opening radical clock rearrangement of the intermediate a ‐cyclopropyl radical into a benzyl radical.

Substitution-Dependent Ring-Opening Hydrosilylation or Dehydrogenative Hydrosilylation of Cyclopropyl Aldehydes and Ketones Catalyzed by Au Nanoparticles
The reaction between hydrosilanes and aryl-substituted cyclopropyl aldehydes or ketonescatalyzed by Au nanoparticles supported on TiO2 provides two distinct ring-opening reaction motifs depending on the substituents. 2-Aryl-substituted cyclopropyl carbonyl compounds form linear enol ethers via formal silyl hydride addition on the carbon atom bearing the aryl group. Under the reaction conditions, the
