  Pharmacological profile of a novel series of NK1 antagonists. In vitro and in vivo potency of benzimidazolone derivatives

  摘要：

  By low throughput examination of our chemical library, compound 7 was selected as a lead NK, antagonist with a K-i of 7.1 nM. Modifications of its structure led to the finding that the in vitro potency could be markedly enhanced by disubstituting the anilino phenyl ring as in compounds 13 or 22. Human binding data correlated rather well with results obtained with in vitro animal mice; compound 13 was the most active with ED50 of 0.001 and 0.3 mg/kg after iv and po administration respectively. Furthermore, antagonist 71 was found to be a potent inhibitor of SP-induced bronchoconstriction in guinea-pigs with an ED50 between 0.1 and 0.03 mg/kg iv. Furthermore, upon oral administration, 71 was observed to be active in a model of SP-induced bronchial hypersensitivity in mice, with an ID50 of around 3 mg/kg.

  通过基于结构的设计发现构象受限的人谷氨酰胺基环化酶抑制剂作为有效的抗阿尔茨海默氏病药物。

  摘要：

  阿尔茨海默氏病（AD）是一种无法治愈的进行性神经退行性疾病，其发病机理不能由一个单一因素定义，而是由多种因素组成。因此，呼吁寻求替代方法来解决AD的多方面问题。在潜在的替代目标中，我们的目标是集中在谷氨酰胺环化酶（QC）上，该酶可降低AD患者大脑中β-淀粉样蛋白的毒性焦磷酸型。基于原型抑制剂1的假定的活性构象，开发了一系列的N-取代的硫脲，脲和α-取代的酰胺衍生物。结构-活性关系分析表明，与非限制性类似物相比，构象受限的抑制剂在体外表现出大大改善的QC抑制作用，几种选择的化合物在AD小鼠模型中显示出理想的治疗活性。对代表性抑制剂的构象分析表明，该抑制剂似乎在活性位点保持ZE构象，因为它对其有效活性至关重要。

  analyses indicated that conformationally restrained inhibitors demonstrated much improved QC inhibition in vitro compared to nonrestricted analogues, and several selected compounds demonstrated desirable therapeutic activity in an AD mouse model. The conformational analysis of a representative inhibitor indicated that the inhibitor appeared to maintain the Z-E conformation at the active site, as it
