Inhibition of glycosidases has great potential in the quest for highly, potent and specific drugs to treat diseases such as diabetes, cancer, and, viral infections. One of the most effective ways of designing such, compounds is by mimicking the transition state. Here we describe the, structural, kinetic, and thermodynamic dissection of binding of two, glucoimidazole-derived compounds, which are among the most potent, glycosidase inhibitors reported to date, with two family 1, beta-glycosidases. Provocatively, while inclusion of the phenethyl moiety, improves binding by a factor of 20-80-fold, this does not appear to result, from better noncovalent interactions with the enzyme; instead, improved, affinity may be derived from significantly better entropic contributions, to binding displayed ...

Publication Abstract from PubMed

Inhibition of glycosidases has great potential in the quest for highly potent and specific drugs to treat diseases such as diabetes, cancer, and viral infections. One of the most effective ways of designing such compounds is by mimicking the transition state. Here we describe the structural, kinetic, and thermodynamic dissection of binding of two glucoimidazole-derived compounds, which are among the most potent glycosidase inhibitors reported to date, with two family 1 beta-glycosidases. Provocatively, while inclusion of the phenethyl moiety improves binding by a factor of 20-80-fold, this does not appear to result from better noncovalent interactions with the enzyme; instead, improved affinity may be derived from significantly better entropic contributions to binding displayed by the phenethyl-substituted imidazole compound.
