  Comparative Metabolomics and Structural Characterizations Illuminate Colibactin Pathway-Dependent Small Molecules

  摘要：

  The gene duster responsible for synthesis of the unknown molecule "colibactin" has been identified in mutualistic and pathogenic Escherichia coli. The pathway endows its producer with a long-term persistence phenotype in the human bowel, a probiotic activity used in the treatment of ulcerative colitis, and a carcinogenic activity under host inflammatory conditions. To date, functional small molecules from this pathway have not been reported. Here we implemented a comparative metabolomics and targeted structural network analyses approach to identify a catalog of small molecules dependent on the colibactin pathway from the meningitis isolate E. coli IHE3034 and the probiotic E. coli Nissle 1917. The structures of 10 pathway-dependent small molecules are proposed based on structural characterizations and network relationships. The network will provide a roadmap for the structural and functional elucidation of a variety of other small molecules encoded by the pathway. From the characterized small molecule set, in vitro bacterial growth inhibitory and mammalian CNS receptor antagonist activities are presented.

  performance of highly efficient aliphatic amines racemization, under mild conditions at 30 °C. The reaction proceeds via the reversible generation of prochiral α-aminoalkyl radicals. The latter may result either from a redox process between the thiyl radical and the amine or from direct hydrogen atom abstraction by thiyl radical. As hydrogen atom donor, the thiol plays a crucial role. While the racemization

  在30°C的温和条件下，在硫醇的存在下进行UV辐照可实现高效脂肪族胺的消旋化。该反应通过前手性α-氨基烷基自由基的可逆生成而进行。后者可能是由于噻吩基和胺之间的氧化还原过程或由噻吩基直接提取氢原子引起的。作为氢原子供体，硫醇起着至关重要的作用。虽然伯胺和仲胺的外消旋都是快速的过程，但叔胺的外消旋却很缓慢。暂定原理是基于光刺激的胺催化的硫醇氧化成相应的二硫化物，这使得反应介质中氢原子供体的浓度以取决于胺的性质的速率下降至痕量。
