  Novel compounds are provided that bind to polo-like kinases through the polo-box domain. In certain embodiments, the novel compounds are PEGylated peptides. The PEGylated peptides in accordance with the invention demonstrate high PBD-binding affinity. In certain embodiments, the PEGylated peptides have also achieved activities in whole cell systems. The invention also provides compounds that bind polo-like kinases through the polo-box domain and possess reduced anionic charge. Further provided are methods of design and/or synthesis of the PEGylated peptides and methods of use thereof. The invention provides methods of use of the compounds and methods of synthesis of the compounds. The compounds of the invention have potential therapeutic activity in view of their binding and inhibitory activities towards Plk1. They are based on the amino acid sequence PLHSpT (phosphorylated Thr). The PEG moiety, when present, is covalently attached at the N-terminus. The invention also encompasses derivatives having substituents on the Pro and/or the His side chains, substituents on the phosphate group, the replacement of His with Gln, the replacement of Pro with a N-substituted Gly, the replacement of Ser with Ala, as well as HS-pT fragments with N-terminal alkoxycarbonyl group and PLHS fragments with a C-terminal glyco-imino-alkylxyalkylamide group.

  本发明提供了一种通过Polo-box结构域结合到Polo-like激酶的新化合物。在某些实施例中，这些新化合物是聚乙二醇化肽。根据本发明，这些聚乙二醇化肽表现出高的PBD结合亲和力。在某些实施例中，这些聚乙二醇化肽还在整个细胞系统中表现出活性。本发明还提供了通过Polo-box结构域结合到Polo-like激酶并具有降低阴离子电荷的化合物。进一步提供了设计和/或合成这些聚乙二醇化肽的方法以及使用它们的方法。本发明提供了这些化合物的使用方法和合成方法。这些化合物由氨基酸序列PLHSpT（磷酸化苏氨酸）构成。当存在PEG基团时，PEG基团以共价键连接在N-末端。本发明还包括具有Pro和/或His侧链置换基团、磷酸酯基团置换基团、His被Gln置换、Pro被N-取代Gly置换、Ser被Ala置换的衍生物，以及具有N-末端烷氧羰基基团的HS-pT片段和具有C-末端糖基亚氨基烷氧基烷酰胺基团的PLHS片段。
