NSC 663284 is a potent, selective inhibitor of Cdc25 dual specificity phosphatases (Ki values are 29, 95 and 89 nM for human Cdc25A, Cdc25B2 and Cdc25C respectively); > 20- and > 450-fold selective over VHR and PTP1B phosphatases respectively. Arrests cells at both G1 and G2/M phase and blocks cdk2 and cdk1 activation. Blocks proliferation of a range of human tumor cell lines (IC50 = 0.2 - 35 μM).
NSC 663284 is also offered as part of the Tocriscreen 2.0 Max and Tocriscreen Epigenetics Library. Find out more about compound libraries available from Tocris.

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.
