  Synthesis of Caprazamycin Analogues and Their Structure−Activity Relationship for Antibacterial Activity

  摘要：

  Synthesis of palmitoyl caprazol 7, which possesses a simple fatty acyl side chain at the 3"'-position of the diazepanone moiety, was carried out and their antibacterial activity was evaluated. The key elements of our approach include the improved synthesis of the key 5'-p-0-aminoribosyl-glycyluridine derivative, installation of the palmitoyl side chain to the cyclization precursor, and the construction of the diazepanone by an intramolecular reductive amination. The second generation synthesis of (+)-caprazol was also established. Palmitoyl caprazol 7 exhibited antibacterial activity against Mycobacterium smegmatis ATCC607 (MIC = 6.25 mu g/mL) with potency similar to that of the caprazamycins (CPZs). Palmitoyl caprazol 7 and N-6'-desmethyl palmitoyl caprazol 28 also exhibited antibacterial activity against drug-resistant bacteria including methyciline-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) strains (MIC = 3.13-12.5 mu g/mL).
