AB In some instances, peptides can play an important role in the discovery
of lead compounds. This paper describes the peptide design facility of
the de novo drug design package, PRO_LIGAND. The package provides a
unified framework for the design of peptides that are similar or
complementary to a specified target. The approach uses single amino acid
residues, selected from preconstructed libraries of different residues
and conformations, and places them on top of predefined target
interaction sites. This approach is a well-tested methodology for the
design of organics but has not been used for peptides before. Peptides
represent a difficulty because of their great conformational flexibility
and a study of the advantages and disadvantages of this simple approach
is an important step in the development of design tools. After a
description of our general approach, a more detailed discussion of its
adaptation to peptides is given. The method is then applied to the
design of peptide-based inhibitors to HIV-1 protease and the design of
structural mimics of the surface region of lysozyme. The results are
encouraging and point the way towards further development of interaction
site-based approaches for peptide design.
