  Application of the Synthetic Aminosugars for Glycodiversification:  Synthesis and Antimicrobial Studies of Pyranmycin

  摘要：

  A divergent approach was employed for the synthesis of aminosugars, from which a novel library of aminoglycoside antibiotics (pyranmycins) was synthesized. Pyranmycins have comparable antibacterial activity as neomycin, a clinically used aminoglycoside antibiotic, against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Mycobacterium smegmatis. In addition, pyranmycins, like streptomycin, are bacteriocidal while isoniazid (INH) is bacteriostatic. Therefore, pyranmycins may provide new therapeutic options in the treatment against tuberculosis. Several members of pyranmycins also manifest modest anti-Tat and anti-Rev activities, which may aid in the development of new anti-HIV agents. Although the antibacterial activity of pyranmycins against aminoglycoside resistant bacteria is less than expected, the synthetic methodologies of utilizing a library of aminosugars can be a model for future studies of glycodiversification or glycorandomization.

  Treatment of methyl 2,3-di-O-benzyl-alpha-D-glucopyranoside (1), methyl 2,3-di-O-acetyl-alpha-D-glucopyranoside (4), 3-O-benzyl-1,2-O-(1-methylethylidene)-alpha-D-glucofuranose (6), 3-O-acetyl-1,2-O-(1-methylethylidene)-alpha-D-glucofuranose (9), 1,2-O-(1-methylethylidene)-alpha-D-xylofuranose (11) and methyl 2,3-di-O-acetyl-alpha-D-galactopyranoside (15) with diisopropylazodicarboxylate-triphenylphosphine in tetrahydrofuran led to the corresponding dioxaphosphoranes, which were opened by trimethylsilyl azide affording the silylated primary azidodeoxysugars. When the same reaction was performed on methyl 2,3-di-O-benzyl-alpha-D-galactopyranoside (20), an inversion of the regioselectivity of the dioxaphosphorane opening was observed, leading mainly to the 4-azido-4-deoxy-alpha-D-glucopyranoside derivative 27.
