biochemical studies and would be useful as an affinityligand for purification of glycosidase. However, its use for the specific inhibition of glucosidase which is highly specific to a glycoside with voluntary aglycon is seriously restricted because no universal method for the synthesis of N-alkylated glyconoamidine has been reported. Here, we report a concise synthesis of N-alkylated Ganem’s glyconoamidine

The synthesis of an affinity gel aimed at leaf-opening factor beta-glucosidase (LOFG) and affinity purification of LOFG is presented. A gluconamidine-based beta-glucosidase inhibitor was used as the ligand of the affinity gel. beta-Glucosidase exhibiting an activity shift throughout the day was selectively purified from Lespedeza cuneata Don by the affinity gel. The resulting LOFG exhibited high substrate specificity toward the leaf-opening factor. (c) 2008 Elsevier Ltd. All rights reserved.
