  Targeting Staphylococcus aureus Quorum Sensing with Nonpeptidic Small Molecule Inhibitors

  摘要：

  A series of 3-oxo-C12-HSL, tetramic acid, and tetronic acid analogues were synthesized to gain insights into the structural requirements for quorum sensing inhibition in Staphylococcus aureus. Compounds active against agr were noncompetitive inhibitors of the autoinducing peptide (AIP) activated AgrC receptor, by altering the activation efficacy of the cognate AIP-1. They appeared to act as negative allosteric modulators and are exemplified by 3-tetradecanoyltetronic acid 17, which reduced nasal cell colonization and arthritis in a murine infection model.

  carboxylic acid (R2CO2H), and the amount of DMAP. Acylation of N-acyl tetramic acids with an alkyl carboxylic acid using 1.3 equiv of DMAP (with 1.1 equiv of DCC) unexpectedly gave the 3-acyltetramic acid directly as a result of acyl migration induced by excess amounts of DMAP. On the other hand, N-unsubstituted, N-alkyl, and N-acyl tetramic acids with alkyl and aromatic carboxylic acids gave the O-acyl tetramic

  已经研究了通过酰基四羧酸与羧酸的O-酰化然后酰基转移来合成3-酰基四酸（生物活性天然产物的子结构）的方法。该酰化序列由N，N′-二环己基碳二亚胺（DCC）和4-二甲基氨基吡啶（DMAP）介导，并且对氮取代基（R 1）的性质，羧酸（R 2 CO 2 H ）的性质非常敏感。），以及DMAP的数量。N-酰化由于过量的DMAP引起的酰基迁移，使用1.3当量的DMAP（含1.1当量的DCC）将酰基四酸与烷基羧酸意外地直接生成了3-酰基四酸。另一方面，通过仅使用0.1当量的DMAP（具有1.1当量的DCC），将N-未取代的，N-烷基和N-酰基的四甲酸与烷基和芳族羧酸一起给出O-酰基的四甲酸。这些可以通过用过量的DMAP处理而进一步重排成酰基产物。发现这些3-酰基四酸在溶液中的互变异构平衡在很大程度上取决于氮取代基（R 1）而不是3-酰基。
