functionalities were prepared and evaluated in the conditioned avoidance response (CAR) test predictive of clinical antipsychotic activity and in in vitro receptor-binding assays. Certain of the compounds display high affinity for the D2, 5-HT1A, and alpha 1-adrenergic receptors. Structures bearing acyclic amide, lactam, and imide functionalities display good biological activity, with a preference for

Dopamine D2-like receptors, especially D2 and D3 receptor subtypes, are important targets of antipsychotic agents. Many of these antipsychotics share an aliphatic linker element between a protonable amine group and an acyl-like moiety. Here, we have modified this aliphatic linker into phenylmethyl and phenylethyl linkers substituted in different positions. The design, synthesis, and in vitro evaluation
多巴胺D 2样受体,特别是D 2和D 3受体亚型,是抗精神病药物的重要靶点。许多这些抗精神病药在可质子胺基和酰基样部分之间共享脂肪族连接元件。在这里,我们将该脂肪族连接体修改为在不同位置取代的苯甲基和苯乙基连接体。本研究对18种多巴胺D 2和D 3受体配体进行了设计、合成和体外评价。使用放射性配体置换测定,发现所有配体对 D 2 R 和D 3 R 具有适度的纳摩尔亲和力。N -(4-2-[4-(2-甲氧基苯基)哌嗪-1-基]乙基}苯基)乙酰胺 ( 6c ) 表现出最高的 D 3 R 和 D 2 R 亲和力值(p K i值为 7.83 [D 2 R] 和 8.04 [D 3 R]),稍微优先于 D 3 R。该衍生物可以是作为开发新型 D 2 R 和 D 3 R 配体的参考结构。
Discovery of a dopamine D4 selective PET ligand candidate taking advantage of a click chemistry based REM linker
Employing D4 selective azaindoles as lead compounds, a focused library of the carbocyclic arene bioisosteres 1 was synthesized when we took advantage of the click chemistry derived triazolylmethyl acrylate resin 2. Ligand binding assays on monoaminergic GPCRs led to SARs that indicated further lead structure optimizations when the attachment of alkoxy substituents provided both an improvement of the biological properties and the opportunity to introduce F-18 as a radioisotope. Finally, radiosynthesis resulted in formation of the radioligand [F-18]7h that showed optimal logD(7.4) of 2.8 and was determined to be highly stable in human serum. Thus, [F-18]7h represents a promising dopamine D4 selective radioligand for positron emission tomography (PET). (C) 2007 Elsevier Ltd. All rights reserved.
