Biological Activity
NSC668394 is a potent ezrin (Thr567) phosphorylation inhibitor, with a Kd of 12.59 μM. NSC668394 inhibit ezrin T567 phosphorylation caused by PKCΙ primarily via their binding to ezrin. NSC668394 can be used to prevent tumor metastasis[1][2][3].
NSC668394 (10 μM; pretreated for 15 min) inhibits ezrin T567 phosphorylation (IC50=8.1 μM) and actin binding in vitro[1].NSC668394 (1-10 μM; 2-6 h) inhibits ezrin-mediated invasion by K7M2 osteosarcoma (OS) cells on the HUVEC monolayer[1].NSC668394 (20 μM) causes significant decrease in growth in JM1 and JM2 rat hepatoma cell lines[2].NSC668394 (10 μM) reduces cell motility phenotypes in zebrafish[1].
NSC668394 (0.226 mg/kg/day; i.p. 5-days a week) inhibits ezrin-dependent in vivo OS metastatic growth in mouse lung[1].
