PLK

AAPK-25 is a potent and selective Aurora/PLK dual inhibitor with anti-tumor activity, which can cause mitotic delay and arrest cells in a prometaphase, reflecting by the biomarker histone H3Ser10 phosphorylation and followed by a surge in apoptosis.

TC-S 7005 is a Polo-like kinases (Plks) inhibitor with IC50s of 4 nM, 24 nM and 214 nM for Plk2, Plk3, and Plk1, respectively.

SBE13 is a potent and selective Plk1 inhibitor, with an IC50 of 200 pM; SBE13 poorly inhibits Plk2 (IC50>66?μM) or Plk3 (IC50=875?nM).

TAK-960 hydrochloride is an orally available, selective inhibitor of polo-like kinase 1 (PLK1), with an IC50 of 0.8 nM at 10 μM ATP; TAK-960 hydrochloride also shows inhibitory activities against PLK2 and PLK3, with IC50s of 16.9 and 50.2 nM, respectively.
