  Pyranmycins, a Novel Class of Aminoglycosides with Improved Acid Stability:  The SAR of d-Pyranoses on Ring III of Pyranmycin

  摘要：

  The synthesis of a novel class of aminoglycosides, pyranmycins, is reported along with the structure activity relationship (SAR) of their antibacterial activity against Escherichia coli. Two pyranmycins show prominent activity (9 muM). Pyranmycins also manifest superior stability in acidic media. The SAR information will lead to the future designs of pyranmycin against drug resistant bacteria.
