title: Synthesis of alpha-L-mannopyranosyl-containing disaccharides and phenols as substrates for the alpha-L-mannosidase activity of commercial naringinase.
abstract: In order to clarify the substrate specificity of the alpha-L-mannosidase activity of naringinase (Sigma), the following disaccharides and phenol glycosides were freshly prepared: methyl 2-O-(alpha-L-mannopyranosyl)-beta-D-glucoside (1), methyl 3-O-(alpha-L-mannopyranosyl)-alpha-D-glucoside (2), methyl 4-O-(alpha-L-mannopyranosyl)-alpha-D-glucoside (3), methyl 5-O-(alpha-L-mannopyranosyl)-beta-D-glucoside (4), methyl 6-O-(alpha-L-mannopyranosyl)-alpha-D-glucoside (5), 6-O-(alpha-L-mannopyranosyl)-D-galactose (6), p-nitrophenyl alpha-L-mannoside (7), and 4-methyl umbelliferone alpha-L-mannoside (8). These compounds, except for 3 and 5 were hydrolyzed with naringinase.
