Replaces Prod. #: ALX-350-281
Cardiotonic steroid specific Na+/K+-ATPase inhibitor. More potent than ouabain (Prod. No. BML-CM109). Induces cell differentiation. Induces apoptosis in U937 and HL-60 cells by activation of AP-1 via a MAPK pathway that involves JNK. Regulates Tiam1 gene. Down regulates expression of 14-3-3 protein.
