STO-609 acetate is a specific inhibitor of the Ca2+/calmodulin-dependent protein kinase kinase (CaM-KK), withKi values of 80 and 15 ng/ml against CaM-KKα and CaM-KKβ isoforms, respectively [1].
CaM-KKα and CaM-KKβ, highly expressed in the brain with the α isoform also expressed in various peripheral tissues such as thymus and spleen in mammals, belongs to Ca2+/calmodulin-dependent protein kinases, which are involved in many cellular responses mediated by an increase in the concentration of intracellular calcium [1].
STO-609 exhibited high selectivity for CaM-KK without significantly affecting the downstream CaM kinases (CaM-KI and -IV), and the IC50 value of STO-609 against CaM-KII was ~ 10 μg/ml. In transfected HeLa cells, STO-609 (0.01 ~ 10 μg/ml) suppressed the Ca2+-induced activation of CaM-KIV in a dose-dependent manner. In addition, in SH-SY5Y neuroblastoma cells, STO-609 at a concentration of 1 μg/ml significantly reduced the endogenous activity of CaM-KK [1].
In ovariectomized mice,in vivo administration of STO-609 (10 μM, 200 μl per mouse, i.p., thrice a week) resulted in increased osteoblasts and diminished osteoclasts, significantly protect adult mice from ovariectomy-induced osteoporosis [2].
