CDC25 Phosphatase Inhibitor II, NSC 663284 is a competitive CDC25 inhibitor and cell cycle arresting compound.?? ??
A cell-permable, potent, irreversible, and competitive inhibitor of the Cdc25 phosphatase family (Ki = 29 nM, 95 nM, and 89 nM for Cdc25A, Cdc25B2, and Cdc25C, respectively) with anti-proliferative properties. Displays nearly 20- and 450-fold greater selectivity over VHR and PTP1B (IC50 = 4.0 μM and >100 μM, respectively). Reported to arrest cell cycle progression, inhibit Cdk dephosphorylation, and delay tumor growth (mean IC50 = 1.5 μM in NCI-60 tumor cell panel). Also shown to block ERK dephosphorylation caused by ectopic Cdc25A expression.???? ??
Potent, selective inhibitor of Cdc25 dual specificity phosphatases (K i values are 29, 95 and 89 nM for human Cdc25A, Cdc25B 2 and Cdc25C respectively); > 20- and > 450-fold selective over VHR and PTP1B phosphatases respectively. Arrests cells at both G 1 and G 2 /M phase and blocks cdk2 and cdk1 activation. Blocks proliferation of a range of human tumor cell lines (IC 50 = 0.2-35 μ M).NSC 663284 ?? ?? ? ???
