Toward bifunctional antibody catalysis
Antibodies that catalyze the deprotonation of unactivated benzisoxazoles to give the corresponding salicylonitriles were prepared using as antigen a 2-aminobenzimidazolium derivative coupled to a carrier protein via its benzene ring. The hapten was designed to induce an antibody binding site with both a base and an acid, in position to initiate proton transfer and stabilize developing negative charge at the phenoxide leaving group, respectively. Consistent with this design, the catalysts exhibit bell-shaped pH-rate profiles, while chemical modification identified several functional groups that could participate in bifunctional catalysis. One of the antibodies, 13G5, is particularly notable in catalyzing the elimination of 6-glutaramidebenzisoxazole with a > 10(5)-fold rate acceleration over background and an effective molarity of > 10(4) M for its catalytic base. These properties compare favorably to the efficiencies achieved by the best previously characterized antibodies with substantially more reactive substrates. (c) 2006 Elsevier Ltd.
