CaMK

CaMK inhibitors block calcium- and calmodulin-dependent protein kinases (CaMKs) in calcium signaling. Calcium/calmodulin-dependent protein kinase II (CaMKII), a multisubunit enzyme abundant at synapses, is central to synaptic strengthening and memory formation, as reviewed in 2002. KN-93, first reported in 1991, and the related isoquinolinesulfonamide KN-62 are classical CaMKII inhibitors. The set also lists KN-93 phosphate and (E)-KN-93 phosphate, salt forms of the same inhibitor. A-484954 targets eukaryotic elongation factor 2 kinase (eEF2K), historically called CaMK III, which controls protein synthesis. The category is mixed and contains protein kinase D (PKD) inhibitors such as kb NB 142-70 and CID 755673, which act on related kinases.
