  Synthesis and Dual D₂ and 5-HT_1A 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.

  A triazole bridged flavonoid dimer compound library was efficiently constructed via the cycloaddition reaction of a series of flavonoid-containing azides (Az 1-15) and alkynes (Ac 1-17). These triazole bridged flavonoid dimers and their precursor alkyne- and azide-containing flavonoids were screened for their ability to modulate multidrug resistance (MDR) in P-gp-overexpressed cell line (LCC6MDR), MRP1-overexpressed cell line (2008/MRP1) and BCRP-overexpressed cell line (HEK293/R2 and MCF7-MX100). Generally, they displayed very promising MDR reversal activity against P-gp-, MRP1- and BCRP-mediated drug resistance. Moreover, they showed different levels of selectivity for various transporters. Overall, they can be divided into mono-selective, dual-selective and multi-selective modulators for the P-gp, MRP1 and BCRP transporters. The EC50 values for reversing paclitaxel resistance (141-340 nM) of LCC6MDR cells, DOX (78-590 nM) and vincristine (82-550 nM) resistance of 2008/MRP1 cells and topotecan resistance (0.9-135 nM) of HEK293/R2 and MCF7-MX100 cells were at nanomolar range. Importantly, a number of compounds displayed EC50 at or below 10 nM in BCRP-overexpressed cell lines, indicating that these bivalent triazoles more selectively inhibit BCRP transporter than the P-gp and MRP1 transporters. Most of the dimers are notably safe MDR chemosensitizers as indicated by their high therapeutic index values.

  通过一系列含有三唑桥联类黄酮二聚物的合成，使用环加成反应，利用一系列含有黄酮基团的叠氮化物（Az1-15）和炔烃（Ac1-17）构建了一个高效的化合物库。这些三唑桥联的类黄酮二聚体及其前体炔基和叠氮基类黄酮被筛选，以评估它们对过表达P-gp的细胞系（LCC6MDR）、MRP1过表达的细胞系（2008/MRP1）和BCRP过表达的细胞系（HEK293/R2和MCF7-MX100）调节多药耐药性（MDR）的能力。总体而言，它们展现了极具前景的P-gp、MRP1和BCRP介导的药物耐药性的MDR逆转活性。此外，它们显示出对各种转运体的不同程度的选择性。总体而言，它们可以分为单选择性、双选择性和多选择性的P-gp、MRP1和BCRP转运体调节剂。对于LCC6MDR细胞的紫杉醇耐药性（141-340 nM）、2008/MRP1细胞的DOX（78-590 nM）和长春新碱（82-550 nM）耐药性以及HEK293/R2和MCF7-MX100细胞的拓扑替康耐药性（0.9-135 nM），它们的EC50值处于纳摩尔范围。重要的是，许多化合物在BCRP过表达的细胞系中显示出EC50值在或低于10 nM，表明这些双价三唑更有选择性地抑制BCRP转运体而不是P-gp和MRP1转运体。大多数二聚体的治疗指数值非常高，表明它们是非常安全的MDR化疗敏感剂。
