  Synthesis and enzyme-inhibitory activity of methyl acarviosin analogues having the α- manno configuration

  摘要：

  Two methyl acarviosin analogues 3a and 4a, having the alpha-manno configuration, and their dihydro derivatives 6a and 7a were synthesised by coupling the protected pseudo-sugar epoxides with methyl 4-amino-4-deoxy- and -4,6-dideoxy-alpha-D-mannopyranoside. Similarly, two analogous compounds 5a and 8a composed of the 1,6-anhydro-beta-D-mannopyranose residues were prepared. Compound 7a showed mild inhibitory activity against Jack bean alpha-D-mannosidase, and 3a was a moderate inhibitor of both alpha-D-mannosidase and yeast alpha-D-glucosidase.

  The methyl α-glycosides of 4-amino-4,6-dideoxy-D-mannopyranose (perosamine), N-acylated with either formic, acetic, or (S)-2,4-dihydroxybutanoic acid, have been synthesized. The 1H and 13C n.m.r. spectra of these substances and the parent, non-N-acylated glycoside, demonstrated how the chemical shifts are influenced by the N-acylation. The N-formyl derivative occurred in two conformations, s-cis and
