    Synthesis and Dual D<sub>2</sub> and 5-HT<sub>1A</sub> Receptor Binding Affinities of 7-piperazinyl and 7-piperidinyl-3,4-dihydroquinazolin-2(1H)-ones
    摘要:
    一系列新的7-哌嗪基和7-哌啶基-3,4-二氢喹唑啉-2(1H)-酮已被合成。所述化合物在结构上与阿多拉嗪相关,后者是一种潜在的不典型抗精神病药物,具有强效的D2受体拮抗剂和5-HT1A受体激动剂特性。制备了适当修饰的芳基溴化物,并与叔丁基哌嗪-1-羧酸酯缩合,得到高级中间体哌嗪基-3,4-二氢喹唑啉-2(1H)-酮。同样,Suzuki-Miyaura交叉偶联反应中,环状乙烯基硼酸盐与适当的芳基溴化物反应,得到哌啶基-3,4-二氢喹唑啉-2(1H)-酮。通过哌嗪基和哌啶基-3,4-二氢喹唑啉-2(1H)-酮与适当设计的联芳基醛的还原胺化反应,完成了这些目标化合物的合成。所述化合物被筛选为D2和5-HT1A受体结合亲和力。结构-活性关系研究表明,环戊烯基吡啶和环戊烯基苄基对这些化合物的双重D2和5-HT1A受体结合亲和力有显著贡献。

    The dihydroquinone derivatives of piperidine and piperazine are 7-piperazinyl and 7-piperadinyl-3,4-dihydroquinazolin-2(1H)-ones that exhibit D2 and 5-HT1A receptor binding affinities, making them suitable for use as the active ingredient of pharmaceuticals for the treatment of schizophrenia. The derivatives have the general formula: where X is carbon or nitrogen and R is a group selected from a through f having the formula: or a pharmaceutically acceptable salt thereof. The piperazine compounds are prepared by condensing 4-bromo-2-nitro-benzonitrile with 1-Boc-piperazine (1-tert-butoxycarbonyl-piperazine) to form an intermediate that is converted to a piperazinyl-3,4-dihydroquinazolin-2(1H)-one. Subsequent reductive amination with the biarylaldehydes a through f completes the synthesis of the 7-piperazinyl-3,4-dihydroquinazolin-2(1H)-ones. The piperadinyl compounds are prepared from tert-butyl-4-(2-oxo-1,2,3,4-tetradihydroquinazolin-7-yl)piperidine-1-carboxylate, which is converted to 7-(piperidin-4-yl)-3,4-dihyroquinazolin-2(1H)-one. Subsequent reductive amination with the biarylaldehydes a through f completes the synthesis of the 7-piperidinyl-3,4-dihydroquinazolin-2(1H)-ones.
