KN-93 hydrochloride is a cell-permeable inhibitor of Ca2+/calmodulin-dependent protein kinase II (CaMK-II) with a Ki of 370 nM. KN-93 HCl inhibits fibroblast CaMK-II activity and cell growth in a dose-dependent manner, reversibly arrests cells in G1 and induces apoptosis. KN-93 also blocks cell growth stimulated by basic fibroblast growth factor, platelet-derived growth factor-BB, and epidermal growth factor in NIH 3T3 fibroblasts. KN-93 (0.5 μM) prevents increased LV developed pressure during action potential prolongation and early afterdepolarizations.
