Three deoxy derivatives of α-mannosidase inhibitor mannostatin A have been synthesized and their inhibitory activity for Jack beans α-mannosidase evaluated in order to elucidate roles of each hydroxyl groups of the inhibitor. The 1- and 2-deoxy derivatives have preserved inhibitory potentials although they lowered the activity one-hundred fold compared to the parent, but the 3-deoxy derivative lost activity.
