  Synthesis and antimicrobial activity of novel globomycin analogues

  摘要：

  Globomycin, a signal peptidase II inhibitor, and its derivatives show potent antibacterial activity against Gram-negative bacteria. The synthesis and antimicrobial activity of novel globomycin analogues are reported. One of the analogues showed a more potent activity against Gram-negative bacteria than globomycin and also exhibited antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA).

  A stereoselective total synthesis of an antibiotic, globomycin (1a), and its congener, SF-1902 A5 (1b), was achieved. Two convergent macrocyclization routes via macrolactamization or macrolactonization to form 1a are described. A conformational study by means of NMR spectroscopy was performed in several solvents. The 1H NMR spectrum of 1a indicated that the amide proton of only the l-allo-Thr residue

  Globomycin (1a), a signal peptidase II inhibitor, and its derivatives show potent antibacterial activity against Gram-negative bacteria. The synthesis and antimicrobial activity of novel globomycin analogues are reported. The hydroxyl group in the L-Ser residue was essential for the antimicrobial activity and the length of the alkyl side chain greatly influenced the activity. In addition, derivatives that had a modified cyclic core exhibited weak activity. One of the analogues showed a wider antimicrobial spectrum, effective against not only Gram-negative but also Gram-positive bacteria. (C) 2003 Elsevier Ltd. All rights reserved.
