  通过在水中形成亚胺自组装具有同手性的纯共价笼

  摘要：

  通过金属-配体配位在水介质中自组装主体分子已得到很好的发展。然而，在水中制备纯共价对应物仍然是一项艰巨的任务。通过在水中缩合三胺和三甲酰基，以[4+4]方式成功地自组装了阴离子四面体笼。尽管每个单独的亚胺键都相当不稳定并且易于在水中水解，但由于多价，四面体非常稳定或惰性。四面体笼及其溶解在有机溶剂中的中性对应物具有同手性，即它们的四个螺旋桨形三甲酰基残基采用相同的旋转构象。笼子能够利用疏水作用来容纳水中的各种客体分子。当手性客人被识别时，笼的一种对映体的形成相对于另一种更有利。因此，笼可以以对映选择性方式生产。在去除手性客体后，四面体能够保持其手性——可能是由于分子内力的协同发生，限制了笼框架中苯基单元的分子内翻转。

  摘要：

  通过自由基介导的 1,5-氢原子转移 (HAT) 机制开发了N-杂环卡宾催化的邻烷基苯甲酰胺的苄基 C-H 酰化和级联环化。与光氧化还原催化不同，这种无光方法能够通过 Breslow 烯醇化物通过单电子转移 (SET) 产生酰胺基自由基。温和的过程可容忍大多数常见的官能团，并以中等到高的收率提供各种二氢异喹啉酮。芳氧基酰胺的电化学特性与基态 SET 假设一致，并提出了一种可能的有机催化转化机制。

  carboxyl-containing DPP-4 inhibitors were highly potent but were poorly bioavailable. Esters of the carboxyl analogs exhibited a significant DPP-4 potency loss albeit with enhanced oral absorption. Herein, we described identification and structure–activity relationship (SAR) exploration of a novel series of benzoic acid and ester derivatives as low single-digit nanomolar DPP-4 inhibitors. Importantly, the

  我们之前报道的含羧基的 DPP-4 抑制剂非常有效，但生物利用度很低。羧基类似物的酯表现出显着的 DPP-4 效力损失，尽管具有增强的口服吸收。在此，我们描述了一系列新型苯甲酸和酯衍生物作为低个位数纳摩尔 DPP-4 抑制剂的鉴定和构效关系 (SAR) 探索。重要的是，酯显示出与酸对应物相当的活性。分子模拟显示酯采用与酸相似的结合方式。此外，所选择的酯和酸表现出高选择性和低细胞毒性，以及良好的代谢稳定性。更重要的是，这些酯类具有出色的口服药代动力学特征。最好的复合酯图19b在体内证明了长时间的 DPP-4 抑制，并在正常和 db/db 小鼠中显着改善了葡萄糖耐量，同时确保了慢性治疗中的降糖效力。我们的结果支持化合物19b可作为治疗 2 型糖尿病的潜在候选药物。
