  Synthesis and activity of 5′-Uridinyl dipeptide analogues mimicking the amino terminal peptide chain of nucleoside antibiotic mureidomycin A

  摘要：

  A series of 5'-uridinyl dipeptides were synthesised which mimic the amino terminal chain of nucleoside antibiotic mureido omycin A. Aminoacyl-beta-alanyl- and aminoacyl-N-methyl-beta-alanyl- dipeptides were attached either via an ester linkage to the 5'-hydroxyl of uridine. or via an amide linkage to 5-amino-5-deoxyuridine. The most active inhibitor of Escherichia coli phosphoMurNAc-pentapeptide translocase (MraY) was 5'-O-((L)-Ala-N-methyl-beta-alanyl)-uridine (131), which also showed 97% enzyme inhibition at 2.35mM concentration, and showed antibacterial activity at 100 mug/mL concentration against Pseudomonas putida. Both the central N-methyl amide linkage and a 5' uridine ester linkage were required for highest biological activity. Enzyme inhibition was shown to be competitive with Mg2+. It is proposed that the primary amino terminus of the inhibitor binds in place of the Mg2+. cofactor at the MraY active site, positioned via a cis-N-methyl amide linkage.
