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.
A cell-permeable 7-substituted quinolinedione compound that displays antiproliferative properties. Acts as a potent, irreversible and mixed competitive inhibitor of the CDC25 phosphatase family (Ki = 29 nM, 95 nM and 89 nM for CDC25A, CDC25B2 and CDC25C, respectively; IC50 = 210 nM for CDC25B2) and displays nearly 20- and 450-fold greater selectivity for the CDC252 phosphatases 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 (IC50 = ~1.5 µM in NCI-60 tumor cell panel). Shown to modify CDC25A catalytic domain and to block cellular ERK dephosphorylation in HeLa-CDC25A cells.
