  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。

  Synthesis and antimycobacterial activity of prodrugs of sulfur dioxide (SO2)

  摘要：

  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.
