Compound Overview
STO-609 acetate is a selective, cell-permeable inhibitor of Ca2+/calmodulin-dependent protein kinase kinase (CaM-KK), with Ki values of 80 ng/mL for recombinant CaM-KKα and 15 ng/mL for CaM-KKβ. It also inhibits AMP-activated protein kinase kinase (AMPKK) activity in HeLa cell lysates, with an IC50 of approximately 0.02 g/mL. It has a molecular formula of C21H14N2O5 and a molecular weight of 374.35 g/mol.

In Vitro
Recombinant CaM-KKα and CaM-KKβ isoforms are inhibited by STO-609 with Ki values of 80 and 15 ng/mL, respectively, and their autophosphorylation activities are inhibited as well. STO-609 is highly selective for CaM-KK, with no significant effect on the downstream CaM kinases (CaM-KI and -IV); its IC50 against CaM-KII is 10 μg/mL. STO-609 inhibits both constitutively active CaM-KKα and the wild-type enzyme. In transfected HeLa cells, STO-609 suppresses Ca2+-induced activation of CaM-KIV in a dose-dependent manner. At 1μg/mL, STO-609 significantly lowers endogenous CaM-KK activity in SH-SY5Y neuroblastoma cells (80% inhibitory rate)[1].
