  硫醇活化的二氧化硫（SO 2）前药作为MRSA抑制剂

  摘要：

  耐药感染在世界范围内变得越来越普遍，并且新的药物开发策略是必需的。在这里，我们报告2，4-二硝基苯磺酰胺的合成和评估，这是一种活性硫物质二氧化硫（SO 2）的供体，作为耐甲氧西林的金黄色葡萄球菌（MRSA）抑制剂。N-（3-甲氧基苯基）-2,4-二硝基-N-（prop-2-yn-1-yl）苯磺酰胺（5e）具有优异的体外MRSA抑制能力。该化合物具有细胞渗透性，并用5e耗尽的细胞内硫醇和增强的氧化物种处理MRSA细胞，两者的结果均与涉及硫醇活化以产生SO 2的机理一致。

• Lewis Acid Mediated Asymmetric [2,3]-Sigmatropic Rearrangement of Allylic Amines. Scope and Mechanistic Investigation
  作者：Jan Blid、Olaf Panknin、Pavel Tuzina、Peter Somfai

  DOI：10.1021/jo062178v

  日期：2007.2.1

  The first asymmetric [2,3]-sigmatropic rearrangement of achiral allylic amines has been realized by quaternization of the amines with an enantiomerically pure diazaborolidine and subsequent treatment with Et3N. The resultant homoallylic amines were obtained in good yields and excellent ee's. The observed diastereo- and enantioselectivities were rationalized by invoking a kinetically controlled process

  通过用对映体纯的二氮杂硼烷胺对胺进行季铵化并随后用Et 3 N处理，已实现了非手性烯丙基胺的第一个不对称[2,3]-σ重排。观察到的非对映体和对映体选择性通过调用动力学控制过程得以合理化，并且通过手性路易斯酸-底物复合物的NMR光谱研究获得了对该模型的支持。通过X射线晶体学分析建立了路易斯酸产物配合物的结构，并支持了所提出的机理。

  amines and 2,4-dinitrobenzenesulfonyl chloride, can be alkylated by the Mitsunobu reaction or by the conventional methods to give N,N-disubstituted sulfonamides in excellent yields. Since 2,4-dinitrobenzenesulfonamides can be removed without deprotecting 2-nitrobenzenesulfonamides, a wide variety of diamines could be prepared by the combined use of these protecting/activating groups.

  可以容易地由伯胺和2，4-二硝基苯磺酰氯制备的2，4-二硝基苯磺酰胺可以通过Mitsunobu反应或通过常规方法进行烷基化，从而以优异的产率得到N，N-二取代的磺酰胺。由于可以在不使2-硝基苯磺酰胺脱保护的情况下除去2，4-二硝基苯磺酰胺，因此可以通过组合使用这些保护/活化基团来制备各种各样的二胺。

• Synthesis and antimycobacterial activity of prodrugs of sulfur dioxide (SO2)
  作者：Satish R. Malwal、Dharmarajan Sriram、Perumal Yogeeswari、Harinath Chakrapani

  Here, we synthesized and studied a library of 2,4-dinitrophenylsulfonamides that closely resembled N-benzyl-2,4-dinitrophenylsulfonamide (1), a thiol-activated prodrug of sulfur dioxide (SO2) which has shown high potency as a Mycobacterium tuberculosis (Mtb) inhibitory agent. The ability of these compounds to generate SO2 in the presence of a thiol was evaluated. A good correlation between pK(aH) of the corresponding amine and reactivity with thiols to generate SO2 was found suggesting that the rate determining step of SO2 generation involved protonation of the amine. Amongst analogues with measurable MICs, we also found a correlation between ability to generate SO2 and Mtb growth inhibitory activity. Together, we report several thiol-mediated prodrugs of SO2 which strongly inhibited Mtb growth (MIC < 1 mu g mL(-1)) with potential for further development as tuberculosis drug candidates.
