  Large-Scale, Protection-Free Synthesis of Se-Adenosyl-l-selenomethionine Analogues and Their Application as Cofactor Surrogates of Methyltransferases

  摘要：

  S-Adenosyl-L-methionine (SAM) analogues have previously demonstrated their utility as chemical reporters of methyltransferases. Here we describe the facile, large-scale synthesis of Se-alkyl Se-adenosyl-L-selenomethionine (SeAM) analogues and their precursor, Se-adenosyl-L-selenohomocysteine (SeAH). Comparison of SeAM analogues with their equivalent SAM analogues suggests that sulfonium-to- selenonium substitution can enhance their compatibility with certain protein methyltransferases, favoring otherwise less reactive SAM analogues. Ready access to SeAH therefore enables further application of SeAM analogues as chemical reporters of diverse methyltransferases.

  sensing (QS), plays a central role in infection in numerous bacterial pathogens. Quorum sensing in Pseudomonas aeruginosa employs a series of small molecule receptors including the master QS regulator, LasR. In this study we investigate a non-natural triaryl series of LasR ligands using a combination of structure activity relationship studies and computational modeling. These studies have enabled the identification

  通过称为群体感应（QS）的过程，细菌化学通讯在众多细菌病原体的感染中起着核心作用。铜绿假单胞菌中的群体感应使用一系列小分子受体，包括主要QS调节剂LasR。在这项研究中，我们使用结构活性关系研究和计算模型相结合的方法研究了LasR配体的非天然三芳基系列。这些研究使得能够鉴定配体结合的关键结构要求，并揭示了诱导LasR的治疗相关拮抗作用的新策略。
