  Design, synthesis, and evaluation of novel 4-thiazolylimidazoles as inhibitors of transforming growth factor-β type I receptor kinase

  摘要：

  A novel series of 4-thiazolylimidazoles was synthesized as transforming growth factor-beta (TGF-beta) type I receptor (also known as activin receptor-like kinase 5 or ALK5) inhibitors. These compounds were evaluated for their ALK5 inhibitory activity in an enzyme assay and their TGF-beta-induced Smad2/3 phosphorylation inhibitory activity in a cell-based assay. N-{[5-(1,3-benzothiazol-6-yl)-4-(4-methyl-1, 3-thiazol-2-yl)-1H-imidazol-2-yl]methyl}butanamide 20, a potent and selective ALK5 inhibitor, exhibited good enzyme inhibitory activity (IC50 = 8.2 nM) as well as inhibitory activity against TGF-beta-induced Smad2/3 phosphorylation at a cellular level (IC50 = 32 nM).

  used groups in organic synthesis. Here, a a series of thianthrenium salts have been synthesized that act as reliable alkylation reagents and readily engage in copper-catalyzed Sonogashira reactions to build C(sp3)−C(sp) bonds under mild photochemical conditions. Diverse alkyl thianthrenium salts, including methyl and disubstituted thianthrenium salts, are employed with great functional breadth, since

  烷基是有机合成中应用最广泛的基团之一。在这里，已经合成了一系列的铪盐，它们作为可靠的烷基化试剂，可以很容易地参与铜催化的 Sonogashira 反应，在温和的光化学条件下建立 C(sp 3 )-C(sp) 键。由于敏感的 Cl、Br 和 I 原子在常规方法中耐受性差，因此可以使用多种烷基铪盐，包括甲基和双取代的铪盐，具有很大的功能广度。在铜催化的熊田反应中也证明了所开发的烷基试剂的通用性。

  Small-ring silacycles are important organosilane species in main-group chemistry and have found numerous applications in organic synthesis. 3-Silaazetidine, a unique small silacycle bearing silicon and nitrogen atoms, has not been adequately explored due to the lack of a general synthetic scheme and its sensitivity to air. Here, we describe that 3-silaazetidine can be easily prepared in situ from diverse

  小环硅杂环化合物是主族化学中重要的有机硅烷物质，在有机合成中有着广泛的应用。3-硅氮杂环丁烷是一种独特的小硅环，含有硅和氮原子，由于缺乏通用合成方案及其对空气的敏感性，尚未得到充分探索。在这里，我们描述了 3-硅氮杂环丁烷可以很容易地从各种空气稳定的前体 (RSO 2 NHCH 2 SiR 1 2 CH 2CL）。3-硅氮杂环丁烷在钯催化的与末端炔烃的扩环反应中显示出优异的官能团耐受性，产生 3-硅杂四氢吡啶和多种硅氮杂环衍生物，它们是发现含硅功能分子的有前途的环骨架。
