Article Abstract

In spite of significant progress in MAO research culminating in the crystallization of the MAO B, many structure-functional aspects of these enzymes still require better characterization. Computer modelling of the substrate/inhibitory binding region of the active site includes consensus overlay of several series of fully reversible and/or tightly bound inhibitors onto a rigid referent inhibitor(s). The shape of resultant mould obviously reflects spatial characteristic features of the substrate/inhibitor binding region. The comparison of the active site mould of MAO B with its crystal structure revealed correctness of this approach. The resultant moulds may be effectively used for virtual screening of molecular databases for new lead-structures. Using this approach we have found several selective MAO A inhibitors in databases and these compounds have never been tested for MAO inhibitory activity.
