title: Preparation of 3-amino-3-deoxy derivatives of trehalose and sucrose and their activities.
abstract: The 3-keto derivatives of trehalose and sucrose respectively were prepared by a one-step enzymatic route using D-glucoside 3-dehydrogenase from Flavobacterium saccharophilum. Reductive amination of 3-ketotrehalose with ammonium acetate and sodium cyanoborohydride gave three compounds, 3-amino-3-deoxy-alpha-D-allopyranosyl alpha-D-glucopyranoside, 3-amino-3-deoxy-alpha-D-glucopyranosyl alpha-D-glucopyranoside (3-trehalosamine) and 3-amino-3-deoxy-alpha-D-mannopyranosyl alpha-D-glucopyranoside. From the reductive amination of 3-ketosucrose, 3-amino-3-deoxy-alpha-D-allopyranosyl beta-D-fructofuranoside and 3-amino-3-deoxy-alpha-D-glucopyranosyl beta-D-fructofuranoside were obtained. The antibiotic and glycohydrolase inhibitory activities of these 3-amino-3-deoxy derivatives were determined.
