Selective Inhibitors of the Polo-Like Kinase 1 Polo-Box Domain

摘要

Inhibitors that are specific for the PBD domain of the PLK1 protein are described. The inhibitors include fragment ligated inhibitors that include one or more amino acids of a starting peptide upon which the inhibitors are based and also include non-peptidic inhibitors. The inhibitors include a benzoic acid-based derivative that mimics the structure activity relationship of amino acid residues of known peptide inhibitors. The inhibitors exhibit high selectivity for the PLK1 isotype.
