Aspartic protease inhibitors designed from computer-generated templates bind as predicted.
[reaction: see text] Novel tripeptide-derived peptidomimetics 1, 7ab, and 8ab, inspired by templates generated by the structure-generating program GrowMol, were synthesized, shown to inhibit Rhizopus chinensis pepsin, and found by X-ray crystallography to bind to the enzyme in the GrowMol-predicted mode. Repetitive evaluation of the computer-generated templates for synthetic feasibility and optimal enzyme interactions led to the designed compounds.
