  Mechanistic Analysis of Muraymycin Analogues: A Guide to the Design of MraY Inhibitors

  摘要：

  The systematic structure activity relationship (SAX) of the muraymycins (MRYs) using an Ugi four-component reaction (U4CR) was investigated. The impact of the lipophilic substituent on antibacterial activity was significant, and the analogues 8 and 9 having a lipophilic side chain exhibited good activity against a range of Gram-positive bacterial pathogens, including MRSA and VRE. Further investigation of compounds 8 and 9 revealed these analogues to be selective inhibitors of the MraY transferase and nontoxic to HepG2 cells. The SAX of the accessory urea peptide moiety indicated that it could be simplified. Our SAX study of the MRYs suggests a probable mechanism for inhibition of the MraY, where the inner moiety of the urea dipeptide motif interacts with the carbohydrate recognition domain in the cytoplasmic loop S. The predicted binding model would provide further direction toward the design of potent MraY inhibitors. This study has set the stage for the generation of novel antibacterial "lead" compounds based on MRYs.

  DOI：10.1002/ejoc.201400140

  日期：2014.3

  Function-oriented synthesis of a class of liponucleoside antibiotics was investigated through rational simplification guided by previous structure–activity relationship studies of caprazamycins and muraymycins to address the issue associated with their molecular complexity. A lactam-fused isoxazolidine scaffold was designed, and a diverse set of lactam-fused isoxazolidines derivatives were constructed

  Reported here is the asymmetric synthesis of N‐Boc‐protected (2S,3S)‐3‐amino‐2‐hydroxyoctadecanoic acid, a component of ralstonin A and ralstoamide A. Key synthetic steps include alkylation of chiral Ni(II) complex of glycine Schiff base, conversion of COOH to keto acid (CO−COOH) and reduction of the carbonyl group to generate α‐hydroxy functionality.
