  Inhibition of 1-Deoxy-d-Xylulose-5-Phosphate Reductoisomerase by Lipophilic Phosphonates: SAR, QSAR, and Crystallographic Studies

  摘要：

  1-Deoxy-D-xylulose-5-phosphate reductoisomerase (DXR) is a novel target for developing new antibacterial (including antituberculosis) and antimalaria drugs. Forty-one lipophilic phosphonates, representing a new class of DXR inhibitors, were synthesized, among which 5-phenylpyridin-2-ylmethylphosphonic acid possesses the most activity against E. coli DXR (EcDXR) with a K-i of 420 nM. Structure-activity relationships (SAR) are discussed, which can be rationalized using our EcDXR:inhibitor structures, and a predictive quantitative SAR (QSAR) model is also developed. Since inhibition studies of DXR from Mycobacterium tuberculosis (MtDXR) have not been performed well, 48 EcDXR inhibitors with a broad chemical diversity were found, however, to generally exhibit considerably reduced activity against MtDXR. The crystal structure of a, MtDXR:inhibitor complex reveals the flexible loop containing the residues 198-208 has no strong interactions with the 3,4-dichlorophenyl group of the inhibitor, representing a structural basis for the reduced activity. Overall, these results provide implications in the future design and development of potent DXR inhibitors.

• Copper(II) Acetate‐Catalyzed Synthesis of Phosphorylated Pyridines <i>via</i> Denitrogenative C−P Coupling between Pyridotriazoles and P(O)H Compounds

  日期：2018.11.5

  A new inexpensive copper‐catalyzed denitrogenative C−P coupling reaction of pyridotriazoles with P(O)H compounds has been developed. The reaction proceeds via a process of copper‐catalyzed P(O)−H insertion into the pyridyl carbene intermediates generated in situ from pyridotriazoles. This reaction provides a new and effective method for the synthesis of a variety of 2‐picolylphosphoryl compounds.

  吡啶三唑与P（O）H化合物的新型廉价铜催化脱氮C-P偶联反应已得到开发。该反应通过铜催化的P（O）-H插入由吡啶三唑原位生成的吡啶基卡宾中间体的过程进行。该反应为合成各种2-picolylphosphoryl化合物提供了一种新的有效方法。

  日期：1991.2

  Cycloadditions of nitrile oxides with unprotected homoallyl alcohols, followed by Swern oxidations, lead to 5-(2-oxoalkyl)-2-isoxazolines. Subsequent Raney Ni reduction of the resulting heterocycles in ethanol in the presence of excess tetrafluoroboric acid affords substituted pyridine derivatives.

  腈氧化物与未保护的高烯丙醇的环加成，然后是 Swern 氧化，产生 5-(2-氧代烷基)-2-异恶唑啉。随后在过量四氟硼酸存在下，在乙醇中对所得杂环进行 Raney Ni 还原，得到取代的吡啶衍生物。
