  Design, Synthesis, and Evaluation of New Thiadiazole-Based Direct Inhibitors of Enoyl Acyl Carrier Protein Reductase (InhA) for the Treatment of Tuberculosis

  摘要：

  Mycobacterial enoyl acyl carrier protein reductase (InhA) is a clinically validated target for the treatment of tuberculosis infections, a disease that still causes the death of at least a million people annually. A known class of potent, direct, and competitive InhA inhibitors based on a tetracyclic thiadiazole structure has been shown to have in vivo activity in murine models of tuberculosis infection. On the basis of this template, we have here explored the medicinal chemistry of truncated analogues that have only three aromatic rings. In particular, compounds 8b, 8d, 8f, 8l, and 8n show interesting features, including low nanomolar InhA IC50, submicromolar antimycobacterial potency, and improved physicochemical profiles in comparison with the tetracyclic analogues. From this series, 8d is identified as having the best balance of potency and properties, whereby the resolved 8d S-enatiomer shows encouraging in vivo efficacy.

  Herein, we report a novel series of highly potent and selective triazolothiadiazole c-Met inhibitors. Starting with molecule 5, we have applied structure-based drug design principles to identify the triazolothiadiazole ring system. We successfully replaced the metabolically unstable phenolic moiety with a quinoline group. Further optimization around the 5,6 bicyclic moiety led to the identification

  在此，我们报告了一系列新的高效和选择性三唑并噻二唑 c-Met 抑制剂。从分子5开始，我们应用了基于结构的药物设计原则来识别三唑并噻二唑环系统。我们成功地用喹啉基团取代了代谢不稳定的酚类部分。围绕 5,6 双环部分的进一步优化导致了21的鉴定。化合物21存在 PDE3 选择性问题，随后的结构知情设计导致化合物23的发现。化合物23具有精细的激酶选择性、优异的效力、良好的 ADME 谱，并在 SNU-5 胃癌异种移植模型中显示出剂量依赖性的抗肿瘤功效。
