  Diarylthiazole: An Antimycobacterial Scaffold Potentially Targeting PrrB-PrrA Two-Component System

  摘要：

  Diarylthiazole (DAT), a hit from diversity screening, was found to have potent antimycobacterial activity against Mycobacterium tuberculosis (Mtb). In a systematic medicinal chemistry exploration, we demonstrated chemical opportunities to optimize the potency and physicochemical properties. The effort led to more than 10 compounds with submicromolar MICs and desirable physicochemical properties. The potent antimycobacterial activity, in conjunction with low molecular weight, made the series an attractive lead (antibacterial ligand efficiency (ALE)>0.4). The series exhibited excellent bactericidal activity and was active against drug-sensitive and resistant Mtb. Mutational analysis showed that mutations in prrB impart resistance to DAT compounds but not to reference drugs tested. The sensor kinase PrrB belongs to the PrrBA two component system and is potentially the target for DAT. PrrBA is a conserved, essential regulatory mechanism in Mtb and has been shown to have a role in virulence and metabolic adaptation to stress. Hence, DATs provide an opportunity to understand a completely new target system for antimycobacterial drug discovery.

  methodologies exist for amine synthesis, but the direct synthesis of primary amines with a fully substituted α carbon center is an underdeveloped area. We report a method which utilizes photoredox catalysis to couple readily available O-benzoyl oximes with cyanoarenes to synthesize primary amines with fully substituted α-carbons. We also demonstrate that this method enables the synthesis of amines with α-trifluoromethyl

  Accessing hindered amines, particularly primary amines α to a fully substituted carbon center, is synthetically challenging. We report an electrochemical method to access such hindered amines starting from benchtop-stable iminium salts and cyanoheteroarenes. A wide variety of substituted heterocycles (pyridine, pyrimidine, pyrazine, purine, azaindole) can be utilized in the cross-coupling reaction

  将受阻胺，特别是伯胺 α 连接到完全取代的碳中心，在合成上具有挑战性。我们报告了一种电化学方法，以从台式稳定的亚胺盐和氰基杂芳烃开始获取此类受阻胺。多种取代的杂环（吡啶、嘧啶、吡嗪、嘌呤、氮杂吲哚）可用于交叉偶联反应，包括被卤化物、三氟甲基、酯、酰胺或醚基团、杂环或未保护的杂环取代的杂环酒精或炔烃。基于 DFT 数据以及循环伏安法和 NMR 光谱的机理洞察表明，质子耦合电子转移机制作为 α-氨基自由基和源自氰基杂芳烃的自由基的杂双自由基交叉偶联的一部分是可操作的。

  Intermediary radical cations, generated through single-electron oxidation of enol silyl ethers by excited Ir-based photocatalysts, can be exploited as Brønsted acids for the activation of heteroarylcyanides. This strategy enables the direct allylic C−H heteroarylation of enol silyl ethers under visible-light irradiation.
