title: Glycosidase inhibitors of gem-diamine 1-N-iminosugars. structures in media of enzyme assays.
abstract: The relationships between structures and inhibitory activities of glycosidase inhibitors of gem-diamine 1-N-iminosugars in media of enzyme assays have been investigated. It has been proved that gem-diamine 1-N-iminosugar smoothly undergoes a structural change to a hydrated ketone or its derivative via a hemiaminal in the media (pH 5.0-6.3), and that the products generated in the media as well as the parent gem-diamine 1-N-iminosugars potently inhibit glycosidases.
