Description: Potent and selective PLK1 inhibitor
Chemical Name: N-[[4-[(6-Chloro-3-pyridinyl)methoxy]-3-methoxyphenyl]methyl]-3,4-dimethoxybenzeneethanamine hydrochloride
Purity: ≥99% (HPLC)

Biological Activity

Selective inhibitor of PLK1 (IC50 values are 200 pM, 875 nM and 66 μM for PLK1, PLK3 and PLK2 respectively). Exhibits no effect on Aurora kinase A activity. Binds and stabilizes the inactive form of PLK1. Delays cell cycle progression, reduces cell proliferation and induces apoptosis in a range of human cancer cell lines. Transiently arrests cells cycle at G0/G1 in primary cells.

Compound Libraries

SBE 13 hydrochloride is also offered as part of the Tocriscreen Plus and Tocriscreen Kinase Inhibitor Toolbox II. Find out more about compound libraries available from Tocris.

Cell Cycle & DNA Damage Repair

Cell Cycle & DNA Damage Repair Poster

In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
