NSC 95397 | CtBP inhibitor; Cdc25 phosphatase inhibitor

NSC 95397 (93718-83-3) is a potent and selective inhibitor of Cdc25 phosphatase (Ki  = 32, 96 and 40 nM for Cdc25A, B and C respectively). NSC-95397 inhibits the growth of several human tumor cell lines and blocks G2/M cell cycle transition.1 Induces cell cycle arrest, phosphorylation of EGFR and activation of ERK-1 and -2.2 Inhibits carboxyl-terminal binding protein a transcriptional corepressor that suppresses multiple pro-apoptotic and epithelial genes.3 Induces eryptosis in human erythrocytes.4
