NSC 95397

NSC 95397 is a potent, selective Cdc25 dual specificity phosphatase inhibitor (K_i=32 nM (Cdc25A), 96 nM (Cdc25B), 40 nM (Cdc25C); IC₅₀=22.3 nM (human Cdc25A), 56.9 nM (human Cdc25C), 125 nM (Cdc25B))^[1]. NSC 95397 inhibits mitogen-activated protein kinase phosphatase-1 (MKP-1) and suppresses proliferation and induces apoptosis in colon cancer cells through MKP-1 and ERK1/2 pathway^[2]. IC50 & Target: Ki: 32 nM (Cdc25A), 96 nM (Cdc25B), 40 nM (Cdc25C)^[1]
IC50: 22.3 nM (human Cdc25A) , 56.9 nM (human Cdc25C), 125 nM (Cdc25B)^[1] In Vitro: NSC 95397 (0, 10, and 20 µM; 24 hour) decreases the cell viability of three colon cancer cell lines SW480, SW620, and DLD-1 in a concentration-dependent manner^[2].
NSC 95397(10 μM; 24 hour) upregulates p21 while downregulates CDK4 and CDK6 were d in all three colon cancer cell lines SW480, SW620, and DLD-1 cells^[2].
NSC 95397 (10 μM; 24 hour) reduces the phosphorylation of retinoblastoma protein (Rb) on Ser795 and Ser807/811^[2].
NSC 95397 (20 μM; 24 hours) significantly increases cleaved caspase-9, -3, -7 and PARP levels^[2].
NSC 95397 (10 μM; 6 hours) enhances the phosphorylation of its downstream ERK1/2 at Thr202/Tyr 204^[2].
