The description provides novel compounds that may serve as anticancer therapeutics. The compounds of the description bind to polo-like kinases through the polo-box domain. The peptide derivatives of the description have achieved improved efficacy in biochemical assays against Plk1. Exemplary compounds of the description include macrocyclic peptidomimetics with high affinity and selectivity for polo-like kinases, which may provide the basis for a new genre of anticancer therapeutics. Other exemplary compounds of the description include bi-valent compounds with that bind to polo-like kinases through both kinase domain and polo-box domain simultaneously by incorporating additional moieties that target Plk1 kinase domain, which significantly enhances affinitity relative and may provide the basis for a new genre of anticancer therapeutics. The description also provides methods of use, methods of preparation, compositions, and kits thereof. Further, the description provides a novel method of design and/or synthesis of phosphoryl-derived peptide derivatives useful as therapeutic agents.
说明提供了可用作抗癌疗法的新型化合物。所述化合物通过 polo-box 结构域与 polo-like 激酶结合。描述中的肽衍生物在生化试验中对 Plk1 的疗效有所提高。本发明的示例化合物包括对polo-like激酶具有高亲和力和选择性的大环肽拟化物,可为新型抗癌疗法奠定基础。本发明的其他示例化合物包括双价化合物,它们通过加入靶向 Plk1 激酶结构域的附加分子,同时通过激酶结构域和 polo-box 结构域与 polo-like 激酶结合,从而显著增强了亲和性,并可为新型抗癌疗法奠定基础。说明还提供了使用方法、制备方法、组合物及其试剂盒。此外,该描述还提供了一种设计和/或合成可用作治疗剂的磷酸衍生肽衍生物的新方法。
