Enzyme isoselective inhibitors: application to drug design.
Common methodologies of computer-assisted drug design focus on noncovalent enzyme-ligand interactions. We introduced enzyme isoselective inhibition trend analysis as a tool for the expert analysis of covalent reversible inhibitors. The methodology is applied to predict the binding affinities of a series of transition-state analogue inhibitors of medicinally important serine and cysteine hydrolases. These inhibitors are isoselective: they have identical noncovalent recognition fragments (RS) and different reactive chemical fragments (CS). Furthermore, it is possible to predict the binding affinities of a series of isoselective inhibitors toward a prototype enzyme and to extrapolate the data to a target medicinally important enzyme of the same family. Rational design of CS fragments followed by conventional RS optimization could be used as a novel approach to drug design.
