  High-Throughput Catch-and-Release Synthesis of Oxazoline Hydroxamates. Structure−Activity Relationships in Novel Inhibitors of Escherichia coli LpxC:  In Vitro Enzyme Inhibition and Antibacterial Properties

  摘要：

  LpxC is a zinc amidase that catalyses the second step of lipid A biosynthesis in Gram-negative bacteria. Oxazolines incorporating a hydroxamic acid, which is believed to coordinate to the single essential zinc ion, at the 4-position are known inhibitors of this enzyme. Some of these enzyme inhibitors exhibit antibacterial activity through their inhibition of LpxC. We recently developed a method for the synthesis of oxazolines using resin capture and ring-forming release that eliminates traditional purification steps and can be used in high-throughput synthesis. Using our method, oxazoline hydroxamates with diverse 2-substituents were prepared in library form as candidate inhibitors for LpxC. Two conventional methods for oxazoline synthesis were also applied to generate more than 70 compounds. The groups at the 2-position included a wide variety of substituted aromatic rings and a limited selection of alkyl groups. These compounds were screened against wild-type and LpxC inhibitor-sensitive strains of Escherichia coli, as well as wildtype Pseudomonas aeruginosa. Inhibition of the E coli LpxC enzyme was also investigated. A broad correlation between enzyme inhibitory and antibacterial activity was observed, and novel compounds were discovered that exhibit antibacterial activity but fall outside earlier-known structural classes.

  to be a metalloproteinase closely related to matrix metalloproteinases (MMPs). Current inhibitors of TACE such as succinate-based hydroxamic acids exemplified by Marimastat (TACE IC(50): 3.8 nM; blood IC(50): 7 microM) and BB1101 (TACE IC(50): 0.2 nM; blood IC(50): 2.3 microM) suffer from modest potency in blood and poor in vivo properties. The introduction of new bulky alpha-substituents into these

  肿瘤坏死因子α转化酶（TACE）是负责将前TNFα转化为TNFα的酶，据报道是与基质金属蛋白酶（MMP）密切相关的金属蛋白酶。目前的TACE抑制剂，例如基于Marimastat（TACE IC（50）：3.8 nM;血液IC（50）：7 microM）和BB1101（TACE IC（50）：0.2 nM;血液IC（50）的琥珀酸异羟肟酸） ：2.3 microM）在血液中具有中等效力且体内特性较差。研究了将新的大体积α-取代基引入这些基于琥珀酸酯的异羟肟酸中。与Marimastat相比，诸如硫醚，磺酰胺和醚等取代物对TACE的效力有所改善。尽管这种改善并未转化为硫醚或醚取代基的更好的血液效力，与Marimastat相比，磺酰胺系列药物对TACE和血液的功效均得到改善。该磺酰胺系列的优化最终确定了杂环双环磺酰胺，例如3t（TACE IC（50）：0.57 nM；血液IC（50）：0.28 microM）。
