Discovery and application of iminotriphenylphosphorane as a formal aromatic primary amine protecting group
摘要:
During our efforts to selectively synthesise N-arylated benzotriazole fragments, we developed a new primary aromatic amine protecting group strategy showing significant advantages over recognised protecting groups. (C) 2012 Elsevier Ltd. All rights reserved.

(methoxyethyl)pyrazole moiety maintained PDE10A inhibition but enhanced selectivity against the other PDEs. Systematic examination and analysis of structure–activity and structure–property relationships resulted in the discovery of 2, an in vitro potent and selectiveinhibitor of PDE10A with high striatal occupancy of PDE10A, promising in vivo efficacy in different rodent behavioral models of schizophrenia, and
我们报告发现了一系列的咪唑并[1,2- a ]吡嗪衍生物作为磷酸二酯酶10A(PDE10A)的新型抑制剂。在高通量筛选活动中,我们鉴定了咪唑并吡嗪衍生物1,一种相对于其他磷酸二酯酶(PDE)具有有限选择性的PDE10A抑制剂。随后的研究1和由(甲氧基乙基)吡唑部分取代三甲氧基苯基保持PDE10A抑制,但提高了对其他PDE的选择性。对结构-活动和结构-财产关系的系统检查和分析导致发现2,一种体外有效和选择性的PDE10A抑制剂,具有较高的PDE10A纹状体占有率,有望在不同的精神分裂症啮齿动物行为模型中发挥体内功效,并在大鼠中具有良好的药代动力学特征。
