  摘要：

  在含胆固醇培养基中对约 150,000 种抗结核分枝杆菌(Mtb)的不同化合物进行表型全细胞高通量筛选，确定 1,3-二芳基吡唑基-酰基磺酰胺1为中等活性命中。构效关系 (SAR) 研究表明，可以将全细胞效力提高到 MIC 值 <0.5 μM，并且开发了一个合理的药效团模型来描述活性化合物的化学空间。化合物在体外对复制的 Mtb 具有杀菌作用，并保留对多重耐药临床分离株的活性。最初的生物学分类分析表明细胞壁生物合成是该系列的一种合理的作用模式。然而，未检测到与已知细胞壁靶标（例如 MmpL3、DprE1、InhA 和 EthA）的交叉耐药性，这表明存在潜在的新作用或抑制模式。建立了该系列中几种活性化合物的体外和体内药物代谢和药代动力学特征，从而确定了用于体内功效概念验证研究的化合物。

  A general protocol for the hydroacylation of styrenes from aliphatic carboxylic acids is reported. These reactions proceed via β-scission of a phosphoranyl radical that is accessed by photoredox catalysis, followed by addition of the resulting acyl radical to the styrenyl olefin. We show that phosphine tunability is critical for efficient intermolecular coupling due to competitive quenching of the

  Compounds are bactericidal in vitro against replicating Mtb and retained activity against multidrug-resistant clinical isolates. Initial biology triage assays indicated cell wall biosynthesis as a plausible mode-of-action for the series. However, no cross-resistance with known cell wall targets such as MmpL3, DprE1, InhA, and EthA was detected, suggesting a potentially novel mode-of-action or inhibition.
