| Hazard Information | Back Directory | [Description]
NSC663284 (383907-43-5) is a potent, selective and irreversible inhibitor of CDC25 phosphatases, Ki=29, 95 and 89 nM for human CDC25A, B2 and C respectively and >20- and >450-fold selective over VHR and PTP1B.1?Arrests cells at G1 and G2/M and inhibits cdk1 and 2 activation.2 Inhibits the growth of a variety of human tumor cell lines.3 NSC663284 acts via irreversible oxidation of the catalytic cysteine of CDC25.4 | [Uses]
CDC25 Phosphatase Inhibitor II, NSC 663284 is a competitive CDC25 inhibitor and cell cycle arresting compound. | [Definition]
ChEBI: 6-chloro-7-[2-(4-morpholinyl)ethylamino]quinoline-5,8-dione is a quinolone. | [General Description]
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. | [Biological Activity]
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). | [Biochem/physiol Actions]
