Cellulase inhibitors were synthesized from cellooligosaccharides and 1-deoxynojirimycin (DNJ) by transglycosylation, using a commercial cellulase. The structures of these cellulase inhibitors were proved to be 4-O-β-cellobiosyl-DNJ, 4-O-β-D-glucopyranosyl-DNJ and 6-O-β-cellobiosyl-DNJ by the results of ^<13>C- and ^1H-NMR analyses. The inhibitory activity of each inhibitor was investigated against several carboxymethylcellulases.
