  发现具有构象约束的恶唑烷酮具有改善的安全性和功效，可用于治疗耐多药结核病。

  摘要：

  结核病仍然是严重的公共卫生挑战，抗结核病新药的研发是全球根除结核病战略的重要组成部分。在这项工作中，我们通过重点研究铅的优化发现了一种构象受限的恶唑烷酮19c，具有改进的抗结核病活性和安全性。与利奈唑胺和舒替利特相比，化合物19c在小鼠TB感染模型中显示出优异的体内功效。在包括动物的微粒体稳定性，细胞毒性，细胞色素P450酶抑制作用和药代动力学在内的一系列测定中证明了化合物19c的可药用性。化合物19c在一系列安全性测定中证明了出色的安全性，包括线粒体蛋白合成，hERG K +，hCav1.2和Nav1.5通道，单胺氧化酶和遗传毒性。在对大鼠进行的为期4周的重复剂量毒理学研究中，19c似乎比利奈唑胺具有更少的骨髓抑制作用，这一直是恶唑烷酮类的主要特征。

  摘要：

  GPR120（FFAR4）是脂肪酸敏感的G蛋白偶联受体（GPCR），已被确定为可能治疗2型糖尿病的靶标。体内设计，合成和评估了含有苯并二氢吡喃骨架的GPR120选择性激活剂。这些努力的结果表明，苯丙氨酸丙酸18是用于进一步动物研究的合适工具分子。化合物18在紧密相关的靶标GPR40（FFAR1）上具有选择性，具有干净的脱靶谱，显示合适的药代动力学特性，并已在野生型/基因敲除GPR120小鼠oGTT研究中进行了评估。
