  Organocatalytic, Diastereo- and Enantioselective Synthesis of Nonsymmetric cis-Stilbene Diamines: A Platform for the Preparation of Single-Enantiomer cis-Imidazolines for Protein–Protein Inhibition

  摘要：

  The finding by scientists at Hoffmann-La Roche that cis-imidazolines could disrupt the protein-protein interaction between p53 and MDM2, thereby inducing apoptosis in cancer cells, raised considerable interest in this scaffold over the past decade. Initial routes to these small molecules (i.e., Nutlin-3) provided only the racemic form, with enantiomers being enriched by chromatographic separation using high-pressure liquid chromatography (HPLC) and a chiral stationary phase. Reported here is the first application of an enantioselective aza-Henry approach to nonsymmetric cis-stilbene diamines and cis-imidazolines. Two novel mono(amidine) organocatalysts (MAM) were discovered to provide high levels of enantioselection (>95% ee) across a broad range of substrate combinations. Furthermore, the versatility of the aza-Henry strategy for preparing nonsymmetric cis-imidazolines is illustrated by a comparison of the roles of aryl nitromethane and aryl aldimine in the key step, which revealed unique substrate electronic effects providing direction for aza-Henry substrate-catalyst matching. This method was used to prepare highly substituted cis-4,5-diaryl imidazolines that project unique aromatic rings, and these were evaluated for MDM2-p53 inhibition in a fluorescence polarization assay. The diversification of access to cis-stilbene diamine-derived imidazolines provided by this platform should streamline their further development as chemical tools for disrupting protein-protein interactions.

  摘要：

  一种新型的含有基于铅化合物8i的苯甲酸部分的联苯类似物已被鉴定为具有良好口服生物利用度和长血浆半衰期的有效和选择性的人β3肾上腺素能受体（β3-AR）激动剂。在研究了铅化合物8i的末端苯环上的进一步取代基作用后，我们发现R位置的更多亲脂取代提高了效能和选择性。这些研究的结果是，在效力，选择性和药代动力学方面取得了最佳平衡，确定了10a和10e是领先的候选药物。另外，评价化合物10a和10e对于由卡巴胆碱引起的膀胱内压力升高是有效的，例如在麻醉狗中膀胱过度活动模型。

  central part of our first generation biphenyl (FGB) series was modified to improve in vitro and in vivo beta3-AR potency without loss of oral bioavailability. First, in this study, we focused our efforts on replacement of the 3-chlorophenyl moiety in the LHS of FGB analogues with 3-pyridyl ring analogues to adjust the lipophilicity. Second, we investigated the replacement of the central part of this

  我们的第一代联苯（FGB）系列的左侧（LHS）和中部进行了改进，以提高体外和体内beta3-AR的效力，而不会降低口服生物利用度。首先，在这项研究中，我们集中精力用3-吡啶基环类似物代替FGB类似物的LHS中的3-氯苯基部分，以调节亲脂性。其次，我们研究了该系列中部的取代，发现将甲基引入苯乙胺部分的α位极大地增强了药效，保持了良好的口服有效性。最后，用基于乙氧基的连接基代替中心部分的两个碳连接基可提供更高的效价和PK分布。这些研究的结果是，一些类似物（例如9h，9k，9l，10g，10m，10p，10r，11b，和11l）被鉴定出与FGB化合物相比，显示出非常高的人β3-AR效能的极佳平衡，高选择性和良好的药代动力学特征。此外，这几种化合物在膀胱过度活动症（OAB）模型中显示出较高的体内功效。这些发现表明，我们选择的第二代联苯（SGB）系列化合物可能是吸引人的成功成功的OAB治疗候选药物。
