We determined that the C-2 position of the thiazole can accommodate a range of lipophilic substitutions, while both the C-4 position and the thiazole core are sensitive to change. The series has good activity against M. tuberculosis growth with sub-micromolar minimum

  2-氨基噻唑系列对全球重要病原体结核分枝杆菌具有抗菌活性。我们通过设计和合成大量类似物并测试它们对结核分枝杆菌以及真核细胞的活性来探索其活性的本质。我们确定噻唑的 C-2 位可以容纳一系列亲脂性取代，而 C-4 位和噻唑核心都对变化敏感。该系列对结核分枝杆菌生长具有良好的活性，可达到亚微摩尔的最低抑制浓度。与其他细菌相比，代表性的类似物对分枝杆菌物种具有选择性，并且对复制的结核分枝杆菌具有快速杀菌作用。作用方式似乎不涉及铁螯合。我们的结论是，该系列作为新型抗结核药物具有进一步开发的潜力。

  Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO) are constitutively overexpressed in many types of cancer cells and exert important immunosuppressive functions. In this article, a series of 4,6-substituted-1H-indazole derivatives were synthesized and evaluated the inhibitory activities against IDO1 and TDO, as well as their structure-activity relationships (SARs). Among these
