Abstract:

The peptidyl prolyl cis/trans isomerase Pin1 has been implicated in the development of cancer, Alzheimer's disease and asthma, but highly specific and potent Pin1 inhibitors remain to be identified. Here, by screening a combinatorial peptide library, we identified a series of nanomolar peptidic inhibitors. Nonproteinogenic amino acids, incorporated into 5-mer to 8-mer oligopeptides containing a d-phosphothreonine as a central template, yielded selective inhibitors that blocked cell cycle progression in HeLa cells in a dose-dependent manner.
