3MB-PP1 is a cell-permeable, potent, ATP-competitive, and highly selective inhibitor of polo-like kinase.

Human polo-like kinase 1 (PLK1) plays dominant role in mitosis and the maintenance of genomic stability. PLK1 is overexpressed in human tumours and exihibits prognostic potential in cancer, indicating its involvement in carcinogenesis and its potential as a therapeutic target [2].

In vitro: 3MB-PP1 treatment significantly changed the DNA state. In TbPLKas cells, after treatment with 3MB-PP1 for 9 h, cells at all cell cycle stages showed an increase in detached new flagella when compared with vehicle control-treated samples [1]. The IC50 value of 3MB-PP1 against Ptoas kinase activity was 120 nM. 3MB-PP1 was not able to significantly inhibit Pti1 and MPK2. 3MB-PP1 significantly potentiated the interactions of Ptoas with AvrPto and AvrPtoB1–387[3].
