STO-609 (acetate) Chemical Properties,Usage,Production

Description

STO-609 (1173022-21-3) is a selective inhibitor of Ca2+-calmodulin-dependent protein kinase kinase (Ki = 80 and 15 ng/ml for inhibition of CaM-KKα and CaM-KKβ respectively).1 Binds to the? ATP-binding site.2 Displays > 80-fold selectivity over CaMK1, CaMK2, CaMK4, MLCK, PKC, PKA and p42 MAPK. Important tool for probing distinct CaMK pathways in LTP.3 Reduces starvation-induced autophagosomal membrane formation.4 Reverses age-associated decline in bone mass.5 Stimulates osteoblast formation, inhibits osteoclast differentiation.6

Uses

STO-609 is a cell-permeable inhibitor of calcium/calmodulin-dependent kinase kinases (CaMKK) isoforms CaMKKα and CaMKKβ. It is used to evaluate the action of CaMKK isoforms both in vitro and in cells.

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.

Biochem/physiol Actions

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

storage

Room temperature (desiccate)
