  Synthesis of iminoalditol analogues of galactofuranosides and their activities against glycosidases

  摘要：

  Iminoalditol analogues of galactofuranosides were synthesized from 1-C-(2'-oxo-propyl)-1,4-dideoxy1,4-imino-D-galactosides and different amines by reductive amination. followed by removal of protecting groups. The activity of these compounds against galactosidases and other glycosidases was investigated. The best inhibitor against beta-galactosidase (bovine liver) is a diastereomeric mixture of an iminoalditol (10h), which contains a hydrophobic hexadecyl aglycon (R=C16H33), whereas no significant inhibitory activity was observed with compounds having a hydrophilic aglycon. Surprisingly, activation of alpha-galactosidase (coffee bean) by 10th was also observed. Because these results were obtained from a mixture of iminoalditols, the inhibition and activation of glycosidases could result from different diastereomers.
