Description

General description

STO-609 reduces tumorigenicity of liver cancer cells in vivo. TO-609 reduces the activation of AMP (adenosine monophosphate)-activated protein kinase (AMPK) by ionomycin in a dose dependant manner.

1:1 adduct with acetic acid

Application

STO609 has been used as a calcium/calmodulin-dependent protein kinase kinase (CAMKK) inhibitor in mouse MLL-AF9 acute myeloid leukemia (AML) cells.

Biochem/physiol Actions

Selective Ca²⁺/Calmodulin-dependent protein kinase kinase (CaM-KK) antagonist. Inhibits CamKKa and CaMKKb with K_i = 80 and 15 ng/mL, respectively. Does not inhibit downstream CaM kinases (CaMKI and CaMKIV).
