  Higher-Affinity Agonists of 5-HT_1AR Discovered through Tuning the Binding-Site Flexibility

  摘要：

  Discovery of high-affinity and high-selectivity agonists of 5-HT1AR. has become very attractive due to their potential therapeutic effects on multiple 5-HT1AR-related psychological and neurological problems. On the basis of our previously designed lead compound FW01 (K-i = 51.9 nM, denoted as 9a in the present study), we performed large-scale molecular dynamics simulations and molecular docking operations on 5-HT1AR-9a binding. We found the flip-packing events for the headgroup of 9a, and we also found that its tail group could bind flexibly at the agornst-binding site of 5-HT1AR. By finely tuning the flip-packing phenomenon of the 9a headgroup and tuning the binding flexibility of 9a tail group, we virtually designed a series of new 9a derivatives through molecular docking operations and first-principles calculations and predicted that these newly designed 9a derivatives should be higher-affinity agonists of 5-HT1AR. The computational predictions on the new 9a derivatives have been confirmed by our wet-experimental studies as chemical synthesis, binding affinity assays, and agonistic-function assays. The consistency between our computational design and wet-experimental measurements has led to our discovery of higher-affinity agonists of 5-HT1AR, with,similar to 50-fold increase in receptor-binding affinity and similar to 25-fold improvements in agonistic function. In addition, our newly designed 5-HT1AR agonists showed very high selectivity of 5-HT1AR over subtype 5-HT2AR and also over three subtypes of dopamine receptors (D-1, D-2, and D-3).

  手性N-杂环碳-铱配合物用于不对称还原前手性酮亚胺

  摘要：

  摘要使用一系列手性半三明治铱配合物，研究了亚胺对映体选择性还原为相应的手性仲胺。这些配合物中的手性N-杂环卡宾（NHC）配体是由易于获得的天然氨基酸合成的。廉价的苯基硅烷被用作方便的氢供体。在优化的条件下，Ir-NHC复合物可以降低酮亚胺的收率，尽管对映体过量（ee）适中。与由该系列其他NHC制备的催化剂相比，苯基甘氨酸衍生的手性NHC被证明可提供最佳的Ir催化剂，并且也可提供最大的ee。当使用带有基于缬氨酸的NHC的Ir配合物时，总是获得还原产物的相反对映异构体。

  Ni/θ-Al2O3, which suggests the cooperation of the acid–base site of θ-Al2O3. For a series of Ni/θ-Al2O3 catalysts with different particle size, the turnover frequency (TOF) per surface Ni increases with decreasing Ni mean particle size, indicating that low-coordinated Ni species and/or metal–support interface are active sites. From these results, we propose that the active site for this reaction is metal–support
