  摘要：

  人17β-羟类固醇脱氢酶10型是一种多功能蛋白，参与线粒体内的许多酶和结构过程。该酶被认为与几种神经系统疾病有关，例如智力低下，帕金森氏病或阿尔茨海默氏病，其中该酶与淀粉样β肽相互作用。我们基于苯并噻唑基支架制备了约60种新化合物，并评估了它们的抑制能力和作用机理。最有效的抑制剂在苯环部分包含3-氯和4-羟基取代基，在苯并噻唑部分的6位上具有小的取代基，并且两个部分通过脲连接基连接（4at，4bb和4bg）。这些化合物的IC50值为1-2μM，对底物乙酰乙酰辅酶A表现出无竞争性的作用机理。这些17β-羟基类固醇脱氢酶的非竞争性苯并噻唑基抑制剂是有希望用于神经退行性疾病潜在药物的化合物，值得进一步研究和开发。

  concentration (MIC) of 0.42 μM. In this study, a series of substituted 2-acylamide-1,3-zole analogues were designed and synthesized, and their anti-Mtb activities were analyzed. In total, 17 compounds were found to be potent anti-Mtb agents, especially against the MDR- and XDR-MTB strains, with MIC values < 10 μM. These analogues can inhibit both drug-sensitive and drug-resistant Mtb. Four representative compounds

  DOI：10.1021/acs.orglett.8b04007

  日期：2019.3.1

  operationally simple oxidation–cyanation method for the synthesis of cyanamides is described. The procedure utilizes inexpensive and commercially available N-chlorosuccinimide and Zn(CN)2 as reagents to avoid direct handling of toxic cyanogen halides. It is demonstrated to be amenable for the cyanation of a variety of primary and secondary amines and aniline derivatives as well as a complex synthetic
