STO-609 (acetate)

STO-609 is a calcium/calmodulin-dependent protein kinase kinase (CaMKK) inhibitor (IC50s = 120 and 40 ng/ml for CaMKKalpha and CaMKKbeta, respectively). It is selective for CaMKKs over CaMKI, CaMKII, CaMKIV, MLCK, PKC, PKA, and p42 MAPK (IC50s = > 10,000 ng/ml for all). STO-609 inhibits phosphorylation of CaMKI and AMP-activated protein kinase (AMPK) in chicken sperm in the presence of extracellular calcium, as well as reduces chicken sperm motility, in a concentration-dependent manner. It decreases hypothalamic neuropeptide Y (Npy) and agouti-related protein (Agrp) expression and cumulative food intake in mice when administered intracerebroventricularly as a 20 µM solution at a continuous rate of 0.5 µL/hour. STO-609 (3 µg/animal, i.c.v.) increases cortical, striatal, and total infarct volume in a mouse model of focal transient cerebral ischemia induced by middle cerebral artery occlusion (MCAO).Formal Name: 7-oxo-7H-benzimidazo[2,1-a]benz[de]isoquinoline-3-carboxylic acid, monoacetate.
