Syntheses of biotinylated probe molecules of L-glutathione (GSH) equipped with boronic acid moiety and evaluation of their binding affinities against glutathione-S-transferase (GST) were described. It revealed that the presence of boronic acid moiety in an appropriate position enhances binding affinity of GSH probe toward GST probably by forming a reversible cross-link. Among prepared, the boronate-containing probe 8b exhibited the highest recovering ability of GST from Escherichia coli cell lysate. (C) 2010 Elsevier Ltd. All rights reserved.
