  摘要：

  结核病（TB）仍然是全球性的重大健康问题，因此迫切需要新的治疗方法。病原体结核分枝杆菌驻留在宿主巨噬细胞内并形成生物膜样群落的能力有助于该疾病的持久性和药物耐受性。可以预防或逆转生物膜样表型的化合物有可能与结核病抗生素一起使用，以克服这种耐受性并缩短治疗时间。我们使用耻垢分枝杆菌作为替代生物，报告了两种抑制和分散分枝杆菌生物膜的新的2-氨基咪唑化合物的鉴定，它们与异烟肼和利福平协同作用，可在体外根除预先形成的耻垢分枝杆菌生物膜，对马勒菌无毒，并展示小鼠血浆中的稳定性。

  Background: Several strategies have been reported for the synthesis of thiazole derivatives. Methods: However, many of these methods suffer from several drawbacks. Several modifications have been made to counter these problems. Here, we have synthesized a new series of 2-(2-((1HImidazol- 4-yl)methylene)hydrazinyl)-4-(4-substitutedphenyl)thiazoles without using the catalyst at room temperature. Results:

  背景：已报道了几种合成噻唑衍生物的策略。 方法：但是，这些方法中有许多都有一些缺点。为了解决这些问题，已经进行了一些修改。在这里，我们合成了一系列新的2-（2-（（（1HI咪唑-4-基）亚甲基）肼基）-4-（4-取代的苯基）噻唑，而在室温下不使用催化剂。 结果：合成的化合物的结构已通过质谱，质谱，IR，1H NMR和13C NMR等光谱分析证实。筛选所有合成的化合物对某些革兰氏阳性和革兰氏阴性细菌的体外抗菌活性。 结论：本文讨论的噻唑衍生物具有药理作用，可能为微生物疾病的治疗提供重要的有价值的治疗方法，尤其是针对细菌和真菌感染。

  An efficient approach for α-bromination of aryl alkyl ketones, utilizing a system consisting of aqueous hydrobromic acid as bromine source, sodium nitrite–KI as catalyst, and air as terminal oxidant, has been developed. The method offers advantages of selective monobromination, mild reaction conditions, broad substrate scope, and good yield. The use of air as the terminal oxidant makes the reaction
