STO-609

Research use only, not for human use.

STO-609 is a selective and cell-permeable inhibitor of CaM-KK.

STO-609 is a selective and cell-permeable inhibitor of CaM-KK; inhibits recombinant CaM-KKα and CaM-KKβ with Ki of 80 and 15 ng/ml; without any significant effect on the downstream CaM kinases (CaM-KI and -IV, IC50 >10 ug); suppresses the Ca(2+)-induced activation of CaM-KIV in a dose-dependent manner in transfected HeLa cells; significantly reduces the endogenous activity of CaM-KK in SH-SY5Y neuroblastoma cells (1 ug/ml, 80% inhibition).

STO-609 inhibits the activities of recombinant CaM-KKα and CaM-KKβ isoforms, with Ki values of 80 and 15 ng/mL, respectively, and also inhibits their autophosphorylation activities. STO-609 is highly selective for CaM-KK without any significant effect on the downstream CaM kinases (CaM-KI and -IV), and the IC50 value of the compound against CaM-KII is 10 μg/mL. STO-609 inhibits constitutively active CaM-KKα as well as the wild-type enzyme. In transfected HeLa cells, STO-609 suppresses the Ca2+-induced activation of CaM-KIV in a dose-dependent manner. STO-609 significantly reduces the endogenous activity of CaM-KK in SH-SY5Y neuroblastoma cells at a concentration of 1μg/mL (80% inhibitory rate).
