  Selective Inhibitors of Bacterial Phosphopantothenoylcysteine Synthetase

  摘要：

  Bacterial phosphopantothenotycysteine synthetase (PPCS) catalyzes the formation of phosphopantothenoylcysteine (PPC) from (R)-phosphopantothenate, L-cysteine, and cytidine-5'-triphosphate (CTP) and has been shown to be essential for growth and survival. The reaction proceeds through a phosphopantothenoyl cytidylate, mixed anhydride intermediate. Both structural and kinetic characterization studies on PPCS have shown differences in the nucleobase binding site between the bacterial and human enzyme. We report for the first time the design and synthesis of mimics of the phosphopantothenoyl cytidylate, which proved to be potent inhibitors of PPCS. These compounds were evaluated in vitro against PPCS from human and several species of bacteria and showed marked selectivity (up to 1000-fold) toward the bacterial. enzymes. A phosphodiester intermediate mimic was the most potent of the compounds synthesized and displayed stow-onset, tight-binding kinetics toward E. faecalis PPCS.

  The coenzyme A (CoA) biosynthetic enzymes have been used to produce various CoA analogues, including mechanistic probes of CoA-dependent enzymes such as those involved in fatty acid biosynthesis. These enzymes are also important for the activation of the pantothenamide class of antibacterial agents, and of a recently reported family of antibiotic resistance inhibitors. Herein we report a study on the

  辅酶 A (CoA) 生物合成酶已被用于生产各种 CoA 类似物，包括 CoA 依赖性酶的机械探针，例如参与脂肪酸生物合成的酶。这些酶对于激活泛酰胺类抗菌剂和最近报道的抗生素抗性抑制剂家族也很重要。在此我们报告了泛酸激酶选择性的研究，泛酸激酶是 CoA 生物合成的第一步和限速步骤。开发了一种强大的合成路线，以允许快速访问在 β-丙氨酸部分、羧酸盐或孪生二甲基基团上多样化的泛酸类似物的小型文库。所有衍生物均作为大肠杆菌泛酸激酶 ( Ec潘K）。四种衍生物，全是N-芳香族泛酰胺，被证明与作为Ec PanK底物的基准N-戊基泛酰胺 (N5-pan)等效，而另外两种也具有N-芳香族基团，是为此报道的一些最佳底物酶。这些数据为未来在生产有用的 CoA 类似物时设计 PanK 底物提供了见解。
