The invention provides novel compounds that may serve as anticancer therapeutics. The compounds of the invention bind to polo-like kinases through the polo-box domain. In certain embodiments, the compounds of the invention are POM-protected peptide derivatives. The use of cationic bis-alkyl his residues in combination with a mono POM-protected pho-phoryl group results in a peptide possessing an overall neutral charge. The peptide derivatives of the invention have achieved both good efficacy and an enhanced bioavailability. The invention also provides methods of use, compositions, and kits thereof. Further, the invention provides a novel method of design and/or synthesis of phosphoryl-derived peptide derivatives useful as therapeutic agents.
该发明提供了可能用作抗癌治疗的新化合物。该发明的化合物通过波洛盒结构结合到波洛样激酶。在某些实施方式中,该发明的化合物是POM保护的肽衍生物。在结合了阳离子双烷基组氨酸残基和单个POM保护的磷酸化基团的情况下,得到的肽具有整体中性电荷。该发明的肽衍生物既具有良好的疗效又具有增强的生物利用度。该发明还提供了使用方法、组合物和相关试剂盒。此外,该发明提供了一种新的设计和/或合成磷酸化肽衍生物的方法,这些衍生物可用作治疗剂。
