INHIBITION OF AMINOPEPTIDASES BY PHOSPHONIC ACID AND PHOSPHINIC ACID ANALOGS OF ASPARTIC AND GLUTAMIC ACIDS

More than 30 phosphonic and phosphinic acid analogues of aspartic and glutamic acids were synthesized in order to probe how the structural d ifferences of these molecules were reflected in their ability to inhib it cytosolic (LAP) and microsomal (APM) aminopeptidases. Although most of the compounds studied were found to exert only a modest inhibitory effect, the studies provide some information on the structural requir ements of the binding subsites and catalytic centers of both enzymes.
