Secondary structures tend to be recognizable because they have repeating structural motifs, but mimicry of these does not have to follow such well-defined patterns. Bioinformatics studies to match side-chain orientations of a novel hydantoin triazole chemotype (1) to protein-protein interfaces revealed it tends to align well across parallel and antiparallel sheets, like rungs on a ladder. One set of these overlays was observed for the protein-protein interaction uPA•uPAR. Consequently, chemotype 1 was made with appropriate side-chains to mimic uPA at this interface. Biophysical assays indicate these compounds did in fact bind uPAR, and elicit cellular responses that affected invasion, migration, and wound healing. Steps towards new peptidomimetics. A bottom up approach was used to design a ladder-rung mimic chemotype overlaying across β-hairpins to perturb protein-protein interactions. The chemotype was evaluated on a databank of over 250,000 PDBs followed by biological assays to probe the inhibition of uPA•uPAR protein interactions.
