  Synthesis of oligosaccharides as potential inhibitors of mycobacterial arabinosyltransferases. Di- and trisaccharides containing C-5 modified arabinofuranosyl residues

  摘要：

  The synthesis of a panel of oligosaccharides containing C-5 arabinofuranosyl residues (9-20) is described. These compounds are of interest as potential inhibitors of the alpha-(I --> 5)-arabinosyltransferase involved in the assembly of mycobacterial cell-wall arabinan. In the series of compounds prepared, the 5-OH group on the nonreducing residue(s) is replaced, independently, with an amino, azido. fluoro, or methoxy functionality. The synthesis of the target compounds involved the preparation of a series of C-5 modified arabinofuranosyl thioglycosides (24-26) and their subsequent coupling to the appropriate acceptor species (21-23). Deprotection of the glycosylation products afforded the azido, fluoro, or methoxy analogs directly. The amino derivatives were obtained in one additional step by reduction of the azido compounds.

  noside disaccharide analogs substituted at the 5-position of the non-reducing end sugar were synthesized and tested in vitro against Mycobacterium tuberculosis (M.tb.), Mycobacterium avium complex (MAC) as well as in a cell free assay system for arabinosyltransferase acceptor/inhibitor activity. A few compounds showed interesting inhibitory activity in the cell free assay as well as against the whole
