  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.
